Denial of service attacks can be reduced by replying to DNS requests with a huge range of nothing, and remembering it.
Group known for claiming responsibility for hacking Mark Zuckerberg's Twitter account and the WikiLeaks' DNS attack says it's behind the Vevo breach.
FarSight CEO and DNS master Paul Vixie explains how enterprises, not just telecoms and infrastructure providers, can use DNS to improve cybersecurity.
In one of our previous articles, we analyzed the NeutrinoPOS banker as an example of a constantly evolving malware family.

A week after publication, this Neutrino modification delivered up a new malicious program classified by Kaspersky Lab as Trojan-Banker.Win32.Jimmy.
In July 2017, during an investigation, suspicious DNS requests were identified in a partnerrsquo;s network.

The source of the queries was a software package produced by NetSarang. Our analysis showed that recent versions of the software had been surreptitiously modified to include an encrypted payload that could be remotely activated by a knowledgeable attacker.

Times have changed a lot since then.

The universityrsquo;s web server now runs in the cloud, rather than on my personal workstation, and Python hasnbsp;surpassednbsp;Perl  as the scripting language du jour. Network automation now has a major focus with Python as an extremely important tool.Today Irsquo;m going to show you how to use Python scripts hosted on the box and integrated into IOS.
