Emotet malware nukes itself today from all infected computers worldwide

We’ve had the FBI patching Exchange servers and, as reported here, law enforcement groups uninstalling malware. Maybe we should outsource security management to law enforcement? (joke)…:

[…] After the takedown operation, law enforcement pushed a new configuration to active Emotet infections so that the malware would begin to use command and control servers controlled by the Bundeskriminalamt, Germany’s federal police agency.

Law enforcement then distributed a new Emotet module in the form of a 32-bit EmotetLoader.dll to all infected systems that will automatically uninstall the malware on April 25th, 2021.

Malwarebytes security researchers Jérôme Segura and Hasherezade took a closer look at the uninstaller module delivered by law enforcement-controlled to Emotet servers.

After changing the system clock on a test machine to trigger the module, they found that it only deletes associated Windows services, autorun Registry keys, and then exits the process, leaving everything else on the compromised devices untouched.

“For this type of approach to be successful over time, it will be important to have as many eyes as possible on these updates and, if possible, the law enforcement agencies involved should release these updates to the open internet so analysts can make sure nothing unwanted is being slipped in,” Marcin Kleczynski, CEO of Malwarebytes, told BleepingComputer.

“That all said, we view this specific instance as a unique situation and encourage our industry partners to view this as an isolated event that required a special solution and not as an opportunity to set policy moving forward.”
