Facebook and Apple have become the latest companies to reveal they had been the target of a “sophisticated cyber-attack” by hackers last month. Although security was breached both companies confirmed that they had found no evidence any user data had been compromised.
In a blog post on its website Facebook explained what it knew of the cyber-attack:
A botnet that was believed to have illegally infected somewhere between 300,000 and 8 million machines and was raking in an estimated $1 million a year has been shut down by security experts. The Bamital botnet was shut down when teams working with Microsoft and Symantec anti-virus specialists raided several data centres in the US. Microsoft and Symantec claim that the computers infected by the Bamital botnet were being used illegally for identity theft. Thousands of affected users have been offered free tools to help to clean up infected machines.
