Deep computer turned into Microsoft

Security firm Sophos has warned users of e-mail about a new computer virus that spreads quickly with a sophisticated distribution. It is disguised as an email to the user mailbox with the notice of providing a copy of Internet Explorer 7 from Microsoft for download.

Not only that, it also made the world surprised by the use of graphics like Microsoft used to promote Internet Explorer 7.0 on their website, click on it, instead of downloading that beta, the code According to the scenario of hackers breaking into the software system , "said outsourcing expert Graham Cluley, Sophos.

Once activated, it finds itself and copies a piece of code into winlogon.exe and creates a Registry change. It also modifies HOSTS files, adds some lines to system.dll and tries to stick to other system files.

Advisor Cluley emphasized that this is a long-standing trick by hackers impersonating Microsoft messages. For the first time in 2003, the Gibe-F worm, also known as Swen, disguised Microsoft's emergency fix, and in 2005 hackers controlled computer users to access a fake website.
