On Thursday April 9th 2015, Europol's Cybercrime Co-ordination Centre (EC3) announced a successful operation to take down the AAEH/Beebone Botnet.
“Operation Source” was a joint effort between international law enforcement agencies, such as the FBI and Europol/EC3, plus multiple private partners, and was co-ordinated by EC3's new Joint Cyber Action Taskforce (J-CAT). J-CAT is located at Europol's headquarters and is a cooperation between EC3, most EU Member States and law enforcement partners around the world.
The polymorphic worm known as W32/Worm-AAEH or Beebone facilitates downloading of other malware (including ZBot banking password stealers, Necurs and ZeroAccess rootkits, Cutwail Spambots, Fake anti-virus and ransomware). It includes worm-like functionality to spread quickly to new machines, and contains a cyclic update routine to replace itself with newer versions to increase likelihood of remaining undetected by anti-virus software. For more detailed information see this report by McAfee or US-CERT's information page.
The Shadowserver Foundation participated in Operation Source by providing operational infrastructure and support, and gathering data on infected clients for the purposes of victim notification and remediation.
The AAEH/Beebone botnet take down occurred on Wednesday April 8th 2015, with 100% of the DGA domains being successfully suspended and sinkholed under US court order. For existing Shadowsever report consumers, the AAEH/Beebone infections will be tagged as "aaeh" in the Drone report.

Operation Source members have worked closely with partners in the anti-virus industry to provide tools to disinfect infected computers. However, the AAEH/Beebone malware can block connections to known anti-virus vendor sites, so your normal desktop tools may not be updating correctly. Shadowserver has provided local copies of the following partner disinfection tools below, in case you are unable to reach your anti-virus vendor's own website:
