June 19th, 2009

Just thought I’d warn everyone

Yesterday afternoon our spam traps caught a piece of malware disguised as a false security alert from Microsoft:

It does look plausible, the spelling and grammar are surprisingly correct,*for malware authors, but, as ever, one should always be cautious concerning e-mail attachments. Even those that purport to come from Microsoft and especially those that contain executables.

Sophos suggests that you go to the official Microsoft website to obtain your fixes since anyone who*succumbed to this scam, far from enjoying*”the highest levels of stability and security“, will now be running*a nasty little*Trojan. *

Sophos detects this threat*as Troj/Spy-CU.
