From PC World: Facebook said police in Greece made two arrests last week in connection with a little-known spamming botnet called “Lecpetex,” which used hacked computers to mine the Litecoin virtual currency.
As many as 50,000 Facebook accounts were affected, and as many as 250,000 computers worldwide, primarily in Greece, Poland, Norway, India, Portugal and the U.S., according to a blog post on Tuesday from Facebook’s Threat Infrastructure team.
The social networking site described the difficulties in shutting down the botnet, whose creators taunted Facebook through messages left on servers that were part of its network.
Those behind Lecpetex launched at least 20 spam campaigns between December 2013 and last month, affecting Facebook and other online services. Some of the victims received private messages containing a “.zip” attachment containing a Java JAR file or Visual Basic script.
