Skype Malware Stealing Victims' Processing Power to Mine Bitcoins

Bitcoin may still be a virtual unknown quantity for most people, but the digital currency has not escaped the notice of attackers, many of whom are turning their attention to finding ways to use the system for their own gains. The attacks against Bitcoin exchange Mt. Gox and hack of Instawallet this week are the latest evidence, but now there is a piece of malware in circulation that is using Skype as a spreading mechanism and then using infected machines' processing power to mine Bitcoins.

The new malware is sending links to Skype users with a message encouraging them to click to see a photo of themselves online. The campaign began yesterday and is still ongoing, with thousands of victims clicking on the malicious link every hour, according to an analysis by Dmitry Bestuzhev of Kaspersky Lab.

The old "See a Photo of you online ..." message should be well enough known by now, of course, with the proliferation of users who have grown up with Facebook and it's ilk, the number of users who are naive enough to fall for this is enough to keep these infections going.

Simple rule

If you get and unexpected Look at Me/ You / Us messages, think before you click

We taught our kids not to talk to, or accept things off strangers, looks like that reasonable advice is no longer valid

Skype runs on my Pentium 4 secondary desktop machine and I run a very tight ship on all my computers with daily trips into Process Explorer (among other things) to see if something strange is going on, so thankfully any "interesting" CPU usage would be readily noticable.
