With several tricks up their sleeves, Wizard Spider—the gang behind the TrickBot trojan—is bouncing back for the second innings. The group has been linked with a new ransomware strain dubbed Diavol that uses Asynchronous Procedure Calls (APCs) and asymmetric algorithms to encrypt files.

Not only TrickBot, but the operators of Mirai have also launched a new botnet named Mirai_ptea that targets a new vulnerability in the KGUARD DVR devices. According to researchers’ telemetry, the botnet is mainly distributed across the U.S., Korea, and Brazil.

Buer Loader and Smoker Loader notoriety also drew researchers’ attention, raising concerns about the rising threat of malware downloaders.
