A recent strain of malware called Cryptolocker (technical description from BleepingComputer
) has been infecting computers across the Internet. It's of the Ransomware (wiki)
genre of attack, and searches a computer's drive for critical files by browsing their extensions (for example, focusing on word processing documents, images and music) and encrypts them with its own key that you can then buy back from the hacker for a fee of $100 to $300 dollars payable in Bitcoins. More information about the virus and how to avoid it is available at Krebs On Security
, and the Malwarebytes Blog
, with more recent developments on Naked Security

In 1984 computer pioneer Ken Thompson wrote one of the seminal works of computer security, Reflections on Trusting Trust [PDF]
. In it he postulated putting a trojan horse inside a compiler as a means of infecting software compiled by it. 25 years later somebody has finally done just that. Researchers at anti-virus house Sophos have discovered a virus
that places a backdoor into applications compiled with the Delphi language. They've identified at least 3000 separate Delphi applications that have had this backdoor compiled into them so far, including banking programs and programs used for cellphone programming.

Microsoft's newest version of Windows....
billed as the most secure ever, contains several serious flaws that allow hackers to steal or destroy a victim's data files across the Internet or implant rogue computer software. The company released a free fix Thursday.
A Microsoft official acknowledged that the risk to consumers was unprecedented because the glitches allow hackers to seize control of all Windows XP operating system software without requiring a computer user to do anything except connect to the Internet.

The Winux virus
is reported to affect both Windows and Linux boxes/applications. The article says it's "written in a primitive computer language called 'assembly language'." On a side note, who do they get to write these articles? Certainly they are uncomfortable with technology...

Up to 20% of the internet vulnerable
to a virus. There is a new Linux worm virus. Apparently, it steals passwords, installs and hides other hacking tools on infected systems, and then uses those systems to seek other servers to attack. Sys admins are advised to run a check on their servers and upgrade their BIND version.
