Researchers have identified a new attack wave propagating MooBot, a version of Mirai botnet. Palo Alto Networks reported that the malware has altered its targeting scope in this campaign. In other news, Cisco Talos stumbled across a new threat, dubbed MagicRAT, by the Lazarus APT group. The infection relies on the successful exploitation of vulnerabilities in VMWare Horizon platforms. The C2 infrastructure for the RAT also spreads new strains of TigerRAT.

Zyxel has released a warning to patch NAS devices after it was made aware of a critical vulnerability in them. With a CVSS v3 severity score of 9.8, the RCE flaw opens the gate to several threats such as elevation of privilege, data theft, and ransomware deployment.

Critical RCE bug in Zyxel NAS devices
Networking equipment vendor Zyxel has addressed a high-severity flaw that impacts its Network-Attached Storage (NAS) devices. Tracked as CVE-2022-34747, the flaw is a format string vulnerability in Zyxel NAS326 firmware versions prior to V5.21(AAZF.12)C0. A hacker can exploit it to pull off RCE-based attacks via a specially crafted UDP packet.
