Sophos warns of fake anti-virus masquerading as Microsoft Update

Security company Sophos has issued a warning about a fake anti-virus attack that masquerades as Microsoft Update.

Sophos says criminals are increasingly looking at ways to lure consumers to download fake antivirus and copying Microsoft's security seems to be their latest strategy.

"We are seeing the criminals behind fake antivirus continuing to customise their social engineering attacks to be more believable to users and presumably more successful," Chester Wisniewski wrote on the Sophos blog post.

"This week they've started to imitate Microsoft Update." According to Sophos, the drive-by page is an exact replica of the real Microsoft Update page, but only appears on Firefox.

"It only comes up when surfing from Firefox on Windows," said Wisniewski. "The real Microsoft Update requires Internet Explorer."

Sophos says the attacks are increasing in complexity and are more accurately targeted and it was time users started looking at communications from software providers with the same level of suspicion previously reserved for fake bank emails.

"They use high quality graphics and are using information from UserAgent strings that are sent by the browser to customise your malware experience," Wisniewski said.

"Just like visiting your bank, you should only trust security alerts in your browser if you initiated a check with Microsoft, Adobe, Sophos or any other vendor for updates to their software."
