"…Altogether it’s been an exceptionally busy week for new computer viruses. As well as the attack described by CA, numerous new versions of the MyTob worm have also been produced. These variants typically pose as warnings from sys admins about the misuse of a potential victim's email account with Subject lines such as "*DETECTED* Online User Violation, Your Email Account is Suspended For Security Reasons and Account Alert." When an infected attachment is launched, MyTob-CM (the most common of this week's variants) attempts to turn off security applications. It also attempts to open a backdoor on infected Windows PC, allowing hackers to exploit compromised systems. Anti-virus firm Sophos reckons the creators of MyTob appear to be a group of virus writers called Hellbot. Carole Theriault, security consultant at Sophos, said similarities in code point to possible links between the authors of MyTob and the long running MyDoom series of worms.
What makes MyTob stand out as a trend is less the number of recorded infections, which are relatively low, than how rapidly it is propagating, according to Trend Micro. The Japanese ant-virus firm has identified 125 new variants spotted in less than three months. "MyTob appears to have been made even easier to implement and vary. This has been a honey pot for lesser skilled programmers - script kiddies - to make their own variants, contributing to the rapid growth rate of MyTob variants in the wild," it said.
One variant, MyTob-AR, seen earlier this week added spyware and adware to infected computers. This malware can be used to track usage including keystrokes and could be used to steal valuable personal information such as passwords, a worrying development in the evolution of the malware family…"
