Watch out for your email inbox because one of the biggest ransomware botnets is back

The Russian-speaking ransomware group taken down by Microsoft and the Pentagon last year is back up and running and ready to infect a whole new tranche of machines. So yeah, time to be really careful about what links and attachments you click on in unsolicited emails. 

The group, known by the moniker of its Trickbot malware, was targeted by the Pentagon’s Cyber Command because of fears that it might decide to interfere with the presidential election. A series of coordinated attacks were launched against infected systems in September 2024, pointing them at a local address rather than a Trickbot control server, and it looked like the debilitating efforts had succeeded.
