In 2014, the high-profile hacks of Sony, the U.S. Postal Service, JP Morgan Chase and iCloud (for celebrity nude photos) dominated the IT security news. Sadly, 2015 wasn’t any better for cyber-security. The volume of hacking attacks that took place this year is becoming more worrisome, and the damage caused by the hack attacks continues to be shocking. Most of the hackers remain at large, which means there is a good chance that they will strike again—or show others how to strike. And what about the thousands of hacks about which the public doesn’t hear? Here’s a scary metric: The average time it takes for an unprotected PC to get hacked after connecting to the Internet is 60 to 90 seconds. Enterprises must think laterally about security in 2016. As hackers exploit weak or stolen passwords in more than 90 percent of security breaches and simply log in as normal users to avoid detection, having multifactor authentication in place is a good way to take security to the next level. In this eWEEK slide show, using industry information from security specialist SMS Passcode, we present the company’s annual Top 10 Global Hack Attacks list, which recalls some of the most high-profile hacks of this past year.
