Linux, often thought of as a more secure alternative to Microsoft, has not had an easy year. We have seen vulnerabilities that affect the iSCSI subsystem, the Extended Berkeley Packet Filter, the Polkit pkexec component bug and now two Kernel bugs. The latest one, dubbed “dirty pipe” It is a method that could allow a “local” user to overwrite read-only files including SUID flies.

Linux has always had something of a mystique about it. Regardless of the distro (flavor) of Linux there simply certain misconception around Linux that are both entertaining and concerning. One of my all-time favorites was/is that it is a “hacker” OS. This fun little misunderstand was so bad at one point that it was part of a parent’s guide on how to tell if your child is a hacker. Nothing says out of touch like labelling an entire OS line as a “hacker” OS. The other side of the coin is the belief that it is secure out of the box. In simple terms, no OS is secure out of the box, all of them have vulnerabilities including serious ones that allow for complete compromise.

WikiLeaks is at it again with their "Vault 7" releases. This time part of the dump features a nice little took kit for continued exploitation of some Linux systems. The tool kit is called OutlawCountry and is, to be perfectly honest, not much more than a remote management, monitoring and exfiltration tool. It is intended to run in the background on a system after a vulnerability has been exploited to allow the payload to be pushed. It looks very similar to a tool that the NSA used for years and has now become the commercial product Kaseya.

When Microsoft announced Windows 8 there were many consumers and people in the industry that raise their eyebrows. Here was an OS designed to integrate with Microsoft cloud services and gaming products. It seemed like a bad move for Microsoft as it put them in competition with many companies that developed games and software for the PC. Still some held out that even though Windows 8 would be more integrated into the Microsoft Eco system than ever it would not mean they could not use whatever software or application they wanted. Microsoft even seemed to confirm this in a few of their building Windows 8 blog posts.
