Help Net Security writes: On April 8, a global operation targeted the Beebone (also known as AAEH) botnet, a polymorphic downloader bot which installs various forms of malware on victims’ computers.

Initial figures show that over 12,000 computers have been infected, however it is likely there are many more. The botnet does not seem the most widespread, however the malware is a very sophisticated one, allowing multiple forms of malware to compromise the security of the victims’ computers.

In the operation, led by the Dutch National High Tech Crime Unit, the J-CAT’s Cyber Liaison Officers worked together with Europol officials and representatives from Intel Security, Kaspersky and Shadowserver.

The botnet was sinkholed by registering, suspending or seizing all domain names with which the malware could communicate and traffic was then redirected. Data will be distributed to the ISPs and CERTs around the world, in order to inform the victims.
