The .Net CLR manages two different heaps, the small object heap (SOH) and the large object heap (LOH).
This article will focus on how the runtime manages the large object heap, and why the large object heap is prone to memory fragmentation that can impact the performance of your application.
It will also discuss the best practices you can use to keep LOH memory fragmentation to a minimum.The garbage collector is quite adept at cleaning up resources that are no longer being used by your application. However, the small object heap and the large object heap work differently. Letrsquo;s start with the small object heap.To read this article in full or to leave a comment, please click here
This second paper is about the methods and techniques that were used by the attackers in the second stage of their attacks against financial organizations – basically enabling remote administration of ATMs.
I try my best to review the latest security suite and antivirus releases from all the security companies, but occasionally I miss one. The 2016 product line from TrustPort slipped past me. I hoped that with two years of innovation rather than the usual one, I would see remarkable improvements in TrustPort Internet Security Sphere, which fared poorly in my last review. Sadly, it didn't score any better than when I last reviewed it in 2015.
At $37.95 per year for three licenses (or $29.95 for a single license), TrustPort is significantly less expensive than most competing products. Bitdefender, Kaspersky, and Norton all cost just a little more than twice as much. On the other hand, those three are much more effective than TrustPort. For the same price, McAfee Internet Security lets you install protection on every Windows, Mac, Android, and iOS device in your household.
The main window for Trustport's antivirus features a single row of five square buttons, while the full suite has two rows of five, to accommodate its additional features. The six green buttons turn components like the real-time scanner and parental control on and off. Blue buttons invoke actions such as running a scan or checking for updates. It's a different arrangement of square buttons from the version I reviewed previously, and a different color scheme, but not a lot else has changed, appearance-wise.
Shared Antivirus Features
This suite's antivirus protection includes everything found in TrustPort Antivirus Sphere, plus an additional Web scanner component. Please read that review for full details of features common to both. I'll summarize here and focus on the suite's additional antivirus abilities.
Several high ratings from the independent testing labs marks a highly effective antivirus. Alas, only one of the labs that I follow includes TrustPort. In its RAP (Reactive And Proactive) test, Virus Bulletin scored TrustPort at 85.34 percent, a little above the average score. But that's not enough data for me to come up with an aggregate lab rating. On a scale of 10 possible points, Kaspersky Internet Security earned an impressive aggregate score of 9.8, while Norton managed 9.7 points.
In my own hands-on malware-blocking test, TrustPort detected 87 percent of the samples and earned 8.5 of 10 possible points. That's one of the lower scores among products I've tested with this sample set. Webroot SecureAnywhere Internet Security Plus, Comodo, G Data, and a few others detected every single sample. Webroot, Comodo, and PC Matic earned a perfect 10 points in this test.
My malicious URL blocking test uses very new malware-hosting URLs. Products get equal credit for blocking all access to the URL and for eliminating the malicious executable during download. Handicapped by lack of any Web-based protection, TrustPort's antivirus managed to wipe out 70 percent of the samples during download. When I tested the suite, its Web scanner blocked access to 21 percent of the URLs, and the real-time antivirus took care of another 55 percent. The total protection rate of 76 percent is still pretty low. Tested in the same way, Symantec Norton Security Deluxe blocked 98 percent of the samples.
Other Shared Features
The antivirus includes a feature called Anti-Exploit, but it's not about blocking attacks that exploit unpatched vulnerabilities, as you might expect. Rather, it looks for suspicious activity, things like programs attempting to manipulate other programs. In its default silent state, it doesn't do anything at all. When I took it out of silent mode and tested it with some valid programs, it found 40 percent of them to be suspicious. To get those programs working, I had to add them to the trusted list.
Next I switched from Anti-Exploit to an alternate tool called Application Inspector and tested again with a collection of valid programs. The Application Inspector flagged 30 percent of them for a different set of suspicious behaviors than Anti-Exploit did. You're better off just leaving this feature in its silent, do-nothing mode.
Clicking the Extra Applications button doesn't actually get you any extra applications, at least not in the standalone antivirus. Rather, it offers access to two different but equally complicated techniques for creating a bootable antivirus. You can use a bootable antivirus to clear up malware infestations that resist normal disinfection. However, the options offered by TrustPort are just too complex for the average user. The full security suite does offer extra applications, which I'll describe below.
Poor Phishing Protection
Phishing is the practice of creating fake versions of sensitive websites and hoping some poor chump takes the bait. Victim who log in to a fake PayPal site, for example, have just given away their credentials to their real PayPal account. These fraudulent sites get blacklisted and taken down quickly, but the fraudsters just reopen with a new fake site.
To test phishing protection, I use the newest phishing URLs I can find, preferably ones that have been reported as fraudulent but not yet analyzed and blacklisted. I try to visit each in a browser protected by the product under test, and in another browser protected by Norton, which has a long history of effective phishing detection. I also launch each URL in Chrome, Firefox, and Internet Explorer, relying on each browser's built-in fraud detection.
The first time TrustPort blocked anything, it popped up the standard notification it uses when it detects malware in a file. I resolved to track such events separately from times when the Web scanner denied all access the fraudulent site. But I didn't need to do that. Not once did I see a page replaced by the Web scanner's warning window. In addition, I found that even when TrustPort reported that it found phishing, the fraudulent page was completely accessible, and I had no trouble entering my (fake) credentials.
Very few products can match Norton's detection rate in this test. Of all recent products, ZoneAlarm tied Norton, while Webroot, Kaspersky, and Bitdefender Internet Security 2017 did a little better. Every other product lagged Norton's detection rate, some by a little, some by a lot.
TrustPort falls in the "by a lot" category. Its detection rate came in 66 percentage points behind Norton's. Chrome and Internet Explorer also beat TrustPort by a wide margin. This is a poor showing.
TrustPort's firewall handled the basic task of fending off outside attack just as well as Windows Firewall. It put the system's ports in stealth mode, making them invisible from the outside, and fended off my port scans and other Web-based attacks. In a recent test, G Data Internet Security 2017 went even further, presenting a notification that it blocked a port scan attack.
Of course, merely doing as well as Windows Firewall isn't a huge accomplishment. Most personal firewalls, TrustPort included, also take control of how programs connect to the Internet and network. Early personal firewalls foisted decision-making on the poor, uninformed user. Should I allow netwhatever.exe to connect with the computer at IP address 220.127.116.11 over port 80? Who knows! Some products, ZoneAlarm among them, cut down on these popups by maintaining a huge database of known good programs and automatically configuring permissions for those.
Norton takes this concept to the next level. If a process isn't in the database, Norton doesn't ask the user what to do. Rather, it monitors that process extra-closely for any suspicious network activity. That's much better than relying on the untrained user for important security decisions.
TrustPort offers four levels of firewall protection, but if you read the text associated with each, it doesn't actually recommend any of them. The default level is called Use Firewall Rules, but the text states this is only recommended for experienced users. The description of the less-strict Enable Outgoing Connections level includes a warning that it can't defend against Trojans and spyware. And there's no point in the options that block or allow all network traffic. For testing, I stuck with the default, Use Firewall Rules.
In this mode, TrustPort is totally old-school. It did correctly pop up a query about my hand-coded browser's use of the network, and it managed to detect a couple leak test programs trying to evade its view. But it also popped up queries for numerous internal Windows components. A user who accepted the default action, blocking that process from Internet access now and forever, would wind up disabling parts of Windows.
Fixing a program blocked in error is also tough with this suite. You click Advanced Configuration, find the Firewall section, and open the Filter Definitions page. Scrolling past dozens and dozens of confusing default rules, you'll eventually find application-specific rules. You could jump in and edit the rule that's blocking the program, but you're better off just deleting the entry and choosing to allow access next time the firewall asks.
Protection against exploit attacks is often a firewall feature. I tested TrustPort's protection by hitting the test system with several dozen exploits generated by the CORE Impact penetration tool. Its Web protection component jumped in to block 30 percent of them, identifying all but one of the exploit attacks by name. Tested in the same way, G Data blocked 50 percent of the exploits. Norton has the best score in this test. It blocked 63 percent of them, all at the network level, before any portion of the exploit reached the test system.
I always investigate methods that a nefarious coder might use to disable firewall protection. TrustPort doesn't seem to store anything in the Registry, so there's no way I could flip the Off switch. I tried to kill its six processes using Task Manager, with no result beyond six Access Denied messages.
However, like G Data, F-Secure Internet Security, and a few others, TrustPort doesn't protect its essential Windows services. I set the Startup Type for all six to disabled and rebooted the system. On reboot, TrustPort didn't run at all. Comodo also didn't protect its services, but on reboot it reported the problem and offered to fix it automatically.
This firewall handles the same tasks that the built-in Windows Firewall does, which is no great feat. Its program control component pops up queries about Windows components; a hapless user who chooses the default block action may disable part of Windows. And the firewall isn't properly hardened against attack. It's not an impressive showing.
See How We Test Security Software
Clicking the big Extra applications button on the main window lets you launch Portunes (rhymes with fortunes) and Skytale (rhymes with Italy). Portunes offers static storage for your passwords and other important data. Skytale encrypts messages. And neither is very useful.
Portunes stores passwords, credit cards, contacts, addresses, and more. You define what it calls a PIN to protect the collection. Last time I reviewed this product, it required a four-digit PIN; now you can enter a respectable master password. That's an improvement, albeit a minor one.
However, Portunes doesn't have any password management features other than including passwords among the things it stores. You can, if you wish, sync your data between multiple installations. To do so, you give Portunes access to your Dropbox account.
As for Skytale, it's easy enough to use. Type or paste in some text, click Encrypt, enter a password, and email or otherwise transmit the resulting gibberish to the recipient, sending the password separately. The catch is, the recipient must also be a TrustPort users. Quite a few encryption utilities don't have that kind of limitation. Some let you create a self-decrypting EXE file, while others offer a free decryption-only tool. Without any similar feature, Skytale isn't terribly useful.
Optimalize Your PC
"Optimalize" may not be precisely English, but it's what the button says. Clicking it launches TrustPort Optima, a simple tune-up utility that deletes temporary files, wipes out useless and erroneous Registry entries, and defragments your disk drives.
You start by clicking Analyze. On my test system, this step went quite quickly for the temporary files and Registry data, but it took quite a while to finish analyzing disk fragmentation. In a similar fashion, the actual cleanup of temp files and Registry went quickly, while defragmentation took quite a bit longer. You can click for a retro view that shows the defrag process as it happens.
If you rely on Web-based mail for your personal email account, you probably don't see much spam, as the major webmail providers filter it out. Likewise, your business email account probably gets filtered at the email server. Given that few people need a spam filter these days, and that my antispam testing was the most lengthy and laborious of all my tests, I dropped that hands-on test last year.
That's a good thing for TrustPort. The last time I reviewed this suite's spam filter, I found it to be quite dismal. It noticeably slowed the process of downloading email, and certain messages caused it to hang, cured only by quickly turning spam filtering off and on again. And its accuracy was terrible. We can hope that the designers have tuned this component since that time.
The spam filter supports Outlook, Outlook Express, Windows Mail, Thunderbird, and The Bat!, but not Windows Live Mail (the replacement for Outlook Express and Windows Mail). Even with these supported email clients, you still must define a message rule to put the spam in its own folder.
You can manually add email addresses or domains to the whitelist or blacklist. However, there's no option to automatically whitelist addresses to which you send mail, or import the address book to the whitelist, the way you can with ESET, Trend Micro Internet Security, and others.
Spam filtering in Check Point ZoneAlarm Extreme Security 2017 is extremely comprehensive and boasts pages and pages of configuration choices. I'm happier with a reduced set of choices, things users can actually understand. TrustPort's advanced spam filter settings are decidedly reduced—there are just four of them—but the average user will get no benefit from meddling with these.
Not everyone has kids, and not every parent wants a parental control utility. For those who do want it, having parental control integrated with the security suite can be convenient. That is, if the parental control component does its job.
TrustPort's Parental Lock is a content filter, nothing more. If you turn it on by clicking its button on the main window, it immediately starts filtering access to websites in five categories: Violence, Porn, Warez, Hacking, and Spyware. You can tweak the configuration to also filter out seven more categories, among them Chat, Shopping, and Drugs.
By default, the filter applies to all users. It's possible to configure it one way for your teen and another way for your toddler, but it's far from easy. Doing so requires using the arcane Windows Select Users dialog. Guys, couldn't you just give Mom and Dad a simple list of user accounts?
In testing, I found that quite a few seriously raunchy sites got past the filter. It doesn't handle secure sites, so any HTTPS porn sites slipped right through. Logging in through a secure anonymizing proxy lifted any limitations by the content filter.
This so-called parental control system is worse than useless. If you want a suite that includes a full-functioning parental control system, look to Norton, Kaspersky, or ZoneAlarm.
More Drag Than Most
The days of resource-hogging security suites that bogged down performance are gone. Users wouldn't accept it, and security companies changed their ways. Few modern suites put a noticeable drag on performance. Even so, there's still a range, and in my hands-on testing TrustPort's performance drag came in on the high side.
Getting all the protective components of a security suite loaded can have an impact on the time it takes to boot up your PC. My boot time test waits for 10 seconds in a row with less than five percent CPU usage, defining that as the time the system is ready for use. Subtracting the start of the boot process, as reported by Windows, yields the boot time. I ran this test 20 times before installing TrustPort and 20 more times afterward, then compared the averages.
The result was so high that I tried again, this time watching the process closely. I found that at each reboot, the firewall was popping up queries about system processes. I manually rebooted the system over and over, responding to all the popups until they stopped coming. When I re-ran the test it still showed a 54 percent increase in boot time. That's one of the biggest impacts among current products. Fortunately, most of us don't reboot any more than we're forced to.
I also measure the suite's impact on simple file manipulation. One test times a script that moves and copies a mixed collection of files between drives. Averaging multiple runs with and without the suite, I found the script took 28 percent longer with TrustPort present. That's a little more than the current average of 23 percent. On the plus side, it didn't exhibit any measurable drag on another script that repeatedly zips and unzips those files.
The average of TrustPort's three performance scores is 27 percent, one of the largest among current products, but I didn't actively notice the test systems seeming slow. At the other end of the spectrum, Webroot had no measurable effect on any of the three tests. Norton averaged just five percent drag, which is quite good.
Typically I'd conclude by summarizing the good and bad points of TrustPort Internet Security Sphere, but there's just not much I can say on the plus side. The independent labs don't rate it, and it fared poorly in our hands-on tests. Its firewall pops up warnings even for Windows internal processes, and it isn't defended against hacking. And the parental control system is worse than useless.
Forget about this suite. Look instead to one of our Editors' Choice security suite products. For a basic security suite, those are Bitdefender Internet Security and Kaspersky Internet Security.

When you can get a seriously full-featured, security-conscious password manager for free, what would entice you to pay? How about even more features, and no limits on existing features? LogMeOnce Password Management Suite Ultimate 5.2 pulls out all the stops, removing limits on the number of shares and beneficiaries, and adding advanced features that include anti-theft and an unusual selfie-based two-factor authentication system. A few quirks in its mobile editions are still being ironed out, but overall, it's a feature-packed password powerhouse.
At $39 per year, LogMeOnce Ultimate costs the same as Dashlane 4.0. Sticky Password goes for $29.99 per year, and LastPass for just $12. But this big, sprawling utility has a ton of features, including some I haven't seen in any competing product.
The free edition doesn't impose any limits on the number of saved passwords, or of synced devices. If you're interested in the product but not sure if you want to pay for it, go ahead and install the free edition, and familiarize yourself with its impressive capabilities. You can upgrade to Ultimate any time the free edition's limits begin to chafe.
The free LogMeOnce Password Management Suite Premium 5.2 is loaded with features, enough that it outperforms many competing products that aren't free. I'll summarize its capabilities here, or you can read my full review of the free edition for more details.
LogMeOnce runs strictly as a browser extension, so it's not limited to a specific platform. If your browser supports extensions, you can use it on Windows, macOS, or even Linux. There are also apps for Android and iOS.
Just about every password manager starts off by asking you to define a strong master password, something that you can remember but that nobody could guess. LogMeOnce now offers password-less authentication as its default. To set this up, you pair your smartphone or mobile device with your LogMeOnce account. Now when you log in on your desktop, you verify when prompted on the mobile device, using a PIN, a fingerprint, or what the company calls PhotoLogin.
Those who've upgraded to Ultimate get more information along with the request for PIN, fingerprint, or PhotoLogin. Swipe left to see the requester's email address, GPS location, IP address, and more, or swipe right to view the location on a map. If you get an unexpected login request, this data may help you figure out who's trolling you.
For PhotoLogin, LogMeOnce snaps a photo with the webcam and sends it to the device. You simply verify that the photo is what you expected. If the computer has no webcam, you can compare a visual one-time password that's sent along with the photo. It's also possible to use PhotoLogin on the mobile device itself, but this isn't quite as secure. It involves you verifying that you are seeing the photo you just snapped; it's a bit self-referential. When I mentioned this to the developers, they quickly modified on-device PhotoLogin to also require entering a PIN.
The free edition captures logins (which it calls applications) as you enter them, and offers to play back your saved credentials when you revisit the site. It also includes a catalog of almost 4,500 known websites. Choose one of these and you can be sure that LogMeOnce will handle it, even if it uses a non-standard login page. However, if you somehow manage to find an oddball login that's not in the catalog, you can't just capture all form fields the way you do with LastPass or Sticky Password Premium. Clicking the browser toolbar button displays all your saved websites. Clicking one of them navigates to the site and logs in.
The password generator defaults to creating 15-character passwords, using all character sets, which yields a very tough password. It also rates any password you type, estimating how long it would take to crack. By default, you must change your master password every three months, without re-using previous passwords. Those using Ultimate can change the password expiry time, in a range from one month to one year.
You can use Google Authenticator, or a workalike such as Duo Mobile or Twilio Authy, for two-factor authentication. Other options in the free edition include receiving a one-time passcode via email, SMS, or voice call. In an unusual move, LogMeOnce charges two credits for each SMS authentication and four credits for each voice call. Those using Ultimate get an allowance of 50 credits per month, with the option to purchase more, $10 for 1,000 credits. I'll cover the Ultimate edition's additional two-factor options below.
An interesting feature called Mugshot gives you a look at anyone who tries to log in on a lost or stolen phone. On any failed login attempt, it snaps photos with the front and rear cameras and sends them to your online dashboard, along with the device's GPS location and IP address. Using this information, you may be able to locate and recover the device. Upgrading to Ultimate gets you a more complete anti-theft system.
LogMeOnce stores personal, address, phone, and company data, for use in filling Web forms. You can save multiple instances of each data type. New since my last review, it also saves and fills credit card data. Like Dashlane, it helpfully displays the saved cards as images, using the color and bank name you specified. It doesn't have the flexibility of form-filling whiz RoboForm Everywhere 7, but it does the job.
Like LastPass and Dashlane, LogMeOnce can display a list of all your passwords, with a strength rating for each, and a flag for any duplicates. In addition, its report page offers several other views on your security, some of which aren't functional in the free edition. If you find you've got weak or duplicate passwords, just click the link next to each one to go change it. For many popular websites, LogMeOnce can even automate the password change process, something few competing products manage.
LogMeOnce includes the ability to securely share passwords with other users. You can choose whether the recipient gets to see the shared password, or just to use it for logging in. There's also an option to define a beneficiary who will receive either your whole account or a specific password in the event of your death. The free edition allows one whole-account beneficiary, five password beneficiaries, and five shared passwords. In the Ultimate edition, there are no such limits.
A productivity dock along the bottom of the screen displays a baker's dozen of live icons that expand when you mouse over them. You can use these icons to quickly reach important features like mugshot or security scorecard. That is, you can if you've paid for the product. Those using the free edition just get a reminder that the productivity dock is only for paid users.
Selfie Two-Factor Authentication
Upgrading to Ultimate unlocks several additional options for two-factor authentication, the most unusual of which is Selfie-2FA. It works like this. You log in to the browser extension, either with the default password-less authentication or a master password. LogMeOnce snaps a webcam photo and sends it to the mobile device you've specified for Selfie-2FA. If the received photo matches what you expected, you simply tap to authorize. MasterCard is exploring a similar type of selfie-based authentication.
What if you're using a desktop device with no webcam? In this case, LogMeOnce sends a generic image with a visual one-time password at the bottom. If the OTP on your mobile device matches the one on your browser, you simply tap to authorize. It's less tech-sexy than using a selfie, but it totally works.
My LogMeOnce contact pointed out that you can make it even harder for an attacker to beat this system by being unpredictable. Just keep changing which of your devices is the one authorized to respond to Selfie-2FA.
Those who've paid for the program can prepare a USB flash drive for use as a physical second authentication factor. There's also an option to add an X.509 Certificate as an authentication factor, but this is more logical in a business setting.
You can enable as many of the two-factor options as you wish, and log in using whichever is logical at the time. For example, if you logging in on a mobile device with no socket for your USB authentication key, you could opt to receive a code via SMS or email, or get a code from Google Authenticator. True Key by Intel Security also offers multiple authentication options, but goes further by letting you require more than just two of them for authentication.
Device Management and Anti-Theft
The free edition receives the GPS location of any failed login attempt, but the paid edition lets you check device location whenever you like. The Device Map page in the Security section displays the location of all your registered devices. Clicking on a device gets you more information, along with a button that remotely logs out of any active LogMeOnce session on the device.
The separate Device Management page lists all the devices you've configured for use with LogMeOnce. If you've lost or replaced a device, you can remove it from the list, thereby disconnecting it from your account. You can flip a switch to define whether each mobile device can accept password-less login requests.
When you select a device from the list, other actions become available. You can send a request to locate a mobile device. A Details tab displays a huge amount of information for iOS devices, quite a bit less for Android devices. However, for Android devices only, you can view a list of installed apps.
The Commands tab appears for both Android and iOS devices, but the available commands differ. You can remotely cause an Android smartphone to ring at top volume, handy in case you've simply misplaced it, and you can lock it remotely using the system lockscreen. You can even change the lockscreen password remotely before locking it down.
On both Android and iOS, you can send a message, perhaps something like, "I've seen your mugshot, phone thief, and I'm coming for you!" But don't get too excited about this feature. Unless you've enabled viewing notifications on the device's lockscreen, the only way a phone thief could read the message would be by logging in to LogMeOnce, which shouldn't be possible.
That brings me to the final command, available on iOS and Android, the Kill-Pill. This dramatically named feature simply wipes all personal LogMeOnce data. I sent the Kill-Pill command to my Apple iPad Air and watched as LogMeOnce reverted to the initial setup screen, with no sign of my email address or any other configuration data. Oddly, sending the same command to my Nexus 9 never worked; it timed out repeatedly in my testing. My company contact confirmed that while the feature works on most Android devices, it doesn't yet work on a Nexus 9. Gotta love Android fragmentation!
Using a trusted mobile device as part of the authentication process is becoming more and more common. Like LogMeOnce in password-less mode, oneID skips the master password in favor of device-based authentication. You can configure True Key to use other forms of authentication, including a trusted device, in place of a master password. But LogMeOnce is the only product I've seen that adds anti-theft features to protect the security of that trusted device. It's a smart move.
Even the free edition of LogMeOnce lists all your passwords ordered by strength, rates your total security status, and displays what it calls a hybrid identity score. If you've paid, you also get an overall password strength rating, with a breakdown of statistics such as the number of passwords of at least 15 characters, and the number that contain at least one of each character type.
The Live PasswordTracker chart is another paid-only feature. It takes two weeks to get a baseline for reporting, so I didn't see its full capabilities. For starters, it charts a solid line that's your overall password strength each day. If you're using the product correctly, that line should only go up. It also charts what the company calls a heartbeat line. Solid line segments represent days that you used LogMeOnce, dotted segments days that you did not. The line's height above the axis is based on the strength of the passwords you used on that day. The purpose of the chart is to encourage you in proper password hygiene, replacing weak passwords with strong ones and always relying on the password manager to keep track.
A Few Oddities
In testing the free edition, I glossed over the few little quirks I ran into, given the fantastic features that you get for free. Running into those same quirks—and a few new ones—in the paid edition, I'm slightly less forgiving.
LogMeOnce is a work in progress, in a good way. While working on this review, I confused the PhotoLogin feature with what was then called Photo-2FA. Overnight, the developers renamed it to Selfie-2FA, to avoid confusion. Because I mused about the possibility of an unauthorized person picking up a phone that was left unlocked, they changed the local-only PhotoLogin to also require PIN entry. This is an agile team, indeed.
On the other hand, I also ran into some oddities that aren't yet fixed. I couldn't make the Kill-Pill personal data erasure work on my Android device. To use Selfie-2FA from my all-in-one desktop PC, I had to crank the webcam brightness to the max, so high that Skype images appeared washed out. On an iPad, the iOS edition runs in the dated 2x mode, just a blown-up version of the iPhone edition. And even though a paid account should be ad-free, the "Go ad-free" link still appears, and I saw ads on some mobile screens. Pending updates for the Android and iOS apps should fix at least some of these oddities. Overall, though, this utility's breadth of features and its inclusion of innovative, security-focused features overshadows these few quirks.
LogMeOnce Password Management Suite Ultimate takes the vast feature set of the free LogMeOnce password manager and kicks it up to the next level. I haven't seen another product offering selfie-based two-factor authentication, or a built in anti-theft system. It lacks the ability to manage password for applications, but it checks just about every other box. On the flip side, you get almost all of these features in the free edition, and for some the vast array of features may prove off-putting.
LastPass Premium comes the closest to matching LogMeOnce's breadth of functionality, though with the latest edition LogMeOnce has taken a significant lead. For those who are more into simplicity and ease than a prodigious number of features, Dashlane 4 does everything you could want, with flair. LogMeOnce joins these two as an Editors' Choice for commercial password managers.
That argument is stronger for open source than it is for closed source." Perry also worried aloud about targeted backdoors delivered to specific users. "The iOS App Store is at a significant disadvantage there even compared to Google Play," he told us. "Each iOS app is re-encrypted specifically for the user with Apple's DRM, making it technically impossible to verify that the package you installed matches the official one." He said that Apple has "created the perfect platform for delivering targeted backdoors to specific users.
I don't like banking on iOS for those reasons." Google hostile to freedom In order to solve the Android security mess, Google is taking steps that hurt user freedom, and make Android vulnerable to compelled backdoors, Perry argued. The fragmentation of the Android ecosystem into multiple OEMs, who distribute their own versions of the operating system, has resulted in rampant insecurity. Without financial incentives to push security updates to users' phones, OEMs by and large abandon users to their fate. Under pressure from many quarters to solve this problem, Google is working to improve Android security, but Perry criticised Google's release and development process as increasingly opaque. Android platform is effectively moving to a 'Look but don't touch' Shared Source model that Microsoft tried in the early 2000s," Perry wrote in his blog post. "However, instead of being explicit about this, Google appears to be doing it surreptitiously. "It is a very deeply disturbing trend." Copperhead to the rescue Copperhead OS was the obvious choice for the prototype's base system, Perry told Ars. "Copperhead is also the only Android ROM that supports verified boot, which prevents exploits from modifying the boot, system, recovery, and vendor device partitions," said Perry in his blog post. "Copperhead has also extended this protection by preventing system applications from being overridden by Google Play Store apps, or from writing bytecode to writable partitions (where it could be modified and infected)." He added: "This makes Copperhead an excellent choice for our base system." Daniel Micay, Copperhead's lead developer, welcomed Perry's prototype. "It will be nice to have somewhere to direct technical users that cannot live without Google Play," he told Ars in an e-mail. By default, Copperhead eschews Google Play, and Micay himself refuses to use any Google Apps. Enlarge / A general outline of Copperhead's main features. "Mike Perry is interested in doing things properly which is why [the prototype] goes through the effort of not breaking verified boot or depending on leaving an insecure recovery image," Micay said. "The rough edges can be smoothed out over time." Mission Improbable, but useable today The prototype, nicknamed "Mission Improbable," is now ready to download and install. Perry said he uses the prototype himself for his personal communications: "E-mail, Signal, XMPP+OTR, Mumble, offline maps and directions in OSMAnd, taking pictures, and reading news and books." He suggests leaving the prototype in airplane mode and connecting to the Internet through a second, less-trusted phone, or a cheap Wi-Fi cell router. The prototype is the second of its kind.
Back in April, 2014, Perry proposed his first Android device optimised for privacy and security—then nicknamed Mission Impossible.
The earlier prototype consisted of a 2013 Google Nexus tablet running Cyanogenmod. Perry emphasised that the Tor Project has no plans to get into the hardware business, but hopes the prototype will provoke discussion and innovation. He pointed to the Neo900, which bills itself as "The truly open smartphone that cares about your privacy"—a project, he said, that came about in part due to the "Mission Impossible" blog post two years ago. "What I’ve found is that posts like this one energise the Android hobbyist/free software ecosystem, and make us aware of each other and common purpose," Perry told Ars. "It also shows Google and others what gaps there are in Android for Tor support, and raises awareness about the dangers the ecosystem faces."

That doesn’t bode well for users of the internet starting next week. “Thanksgiving, Christmas, and the holiday season in general have long been characterized by a rise in the threat of DDoS attacks,” the report says. “Malicious actors have new tools—IoT botnets—that will almost certainly be used in the coming quarter.” That includes the infamous Mirai botnet whose code has been made public and that is responsible for some of the largest DDoS attacks ever – perhaps more than 1Tbps—including two that were mitigated by Akamai. In past years these attacks have been used to take down gamer sites at Christmas, just in time to frustrate people who have just received new gaming platforms.
Famously, both Xbox Live and Sony Playstation were disrupted by DDoS attacks in 2014. Mirai has kept a low profile since it knocked DNS service provider Dyn for a loop last month, but that doesn’t mean it won’t be back, Akamai says. The type of person who likely launched that attack is the type likely to use MIrai for a follow-up to the 2014 attacks.
The Dyn IoT DDoS flood was pinned on gamers who wanted to take down a gaming site, likely Playstation Network. According to Lance James, the chief scientist at Flashpoint, the attack was, “teenagers losing their emotions over videogames,” who “took down more than even the attackers hoped to take down.” DDoS attacks in general have been on the rise, the Akamai report says, up 71% over Q3 last year. The good news is that some forms of DDoS seem to be on the wane, network time protocol (NTP) attacks in particular. That’s because the open NTP servers used to reflect and amplify attack traffic are getting cleaned up, so there are few of them off of which to bounce traffic.
The number of attacks has grown over time but the amount of traffic generated by each has gotten less.
The average size of an NTP attack in June 2014 was greater than 40Gbps.
This June it was 700Mbps. When these attacks were on the rise, the vulnerable servers being used to carry them out became apparent, leading their owners or third party observers to take note and secure them. “It appears that June was the critical inflection point, when not only did available NTP reflection bandwidth shrink, but botnet owners pivoted to other protocols for their traffic,” Akamai says. Meanwhile, UDP fragmentation attacks accounted for nearly a quarter (24.56%) of all DDoS attacks observed by Akamai in the third quarter.
These attacks send fraudulent fragmented packets to the target server, but they are designed so they cannot be reassembled.
That chews up processor time on the server, eventually leading to it becoming overwhelmed. But Akamai says the recent success of IoT botnets means they will be used more until defenders find a way to defeat them. “It is very likely that malicious actors are now working diligently to understand how they can capture their own huge botnet of IoT devices to create the next largest DDoS ever,” Akamai says.
