On Friday, security firm Symantec discovered a Trojan called Backdoor.Makadocs, which in typical backdoor Trojan fashion accesses a compromised system and attempts to swipe data from it. The interesting bit is that it uses Google Docs as a proxy server to get around firewalls and connect to a C&C server, instead of attempting to connect directly.

Using social engineering tactics to engage a user’s interest in the file, the Trojan arrives as a Rich Text Format (RTF) or Microsoft Word document; when a user opens it, the payload is delivered.

Essentially all versions of Windows are affected, from Windows 95 to Windows 7 (and Windows Server 2003 and 2008), and now Symantec says that the malware has been updated to add Windows 8 and Windows Server 2012 to the list, too.


Fortunately for most users, Backdoor.Makadocs appears to be aimed primarily at folks in Brazil. Still, be aware of any suspicious-looking documents, and if you’re a Symantec user, this particular malware will show up as “Trojan.Dropper”.

There's no doubt that this isn't the last piece of malware aimed at Windows 8; every time a new operating system hits the market, it brings with it a fresh batch of nasty software trying to find and exploit vulnerabilities. Fortunately, Windows 8 is handling security fairly well thus far

"Fortunately for most users, Backdoor.Makadocs appears to be aimed primarily at folks in Brazil."

Brazil is the 5th largest country in the world, so the 'fortunately' thing is far from apt.

"Using social engineering tactics to engage a user’s interest in the file,"

In other words, like most Trojans, this one appeals to greed and hormones to get users to do something that is obviously stupid.

I don't think that statement was any slight against Brazil but more that it was localized versus a wide spread attack.

If you know what you're doing, you shouldn't have to worry about this. Unfortunately most users don't have a clue.
