Emotet Malware Destroys Itself From All Infected Computers Emotet, the notorious email-based Windows malware behind several botnet-driven spam campaigns and ransomware attacks, was automatically wiped from infected computers en masse following a European law enforcement operation. The development comes three months after a coordinated disruption of Emotet as part of Operation Ladybird to seize control of servers used to run and maintain the malware network. The orchestrated effort saw at least 700 servers associated with the botnet s infrastructure neutered from the inside, thus preventing further exploitation. Law enforcement authorities from the Netherlands, Germany, the U.S., U.K., France, Lithuania, Canada, and Ukraine were involved in the international action. ....
3.2 Billion Leaked Passwords Contain 1.5 Million Records with Government Emails A staggering number of 3.28 billion passwords linked to 2.18 billion unique email addresses were exposed in what s one of the largest data dumps of breached usernames and passwords.
