Cryptojacking Campaign Targets Misconfigured Docker APIs

A new malware campaign has emerged, targeting misconfigured Docker API instances to create a cryptocurrency mining botnet focused on mining Dero currency. The threat actor exploits insecurely published Docker APIs to gain access to running containerized infrastructures, propagating the malware through a worm-like mechanism to infect other exposed Docker instances. The attack utilizes two main components: a propagation malware named 'nginx' that scans for vulnerable Docker APIs, and a 'cloud' Dero cryptocurrency miner. This campaign has been linked to previous cryptojacking operations and poses a significant risk to any network with insecure Docker APIs.

New Malware Campaign Targets Chinese-Speaking Users with Winos 4.0

Cybersecurity researchers have uncovered a malware campaign that employs fake software installers disguised as popular applications like LetsVPN and QQ Browser to deliver the Winos 4.0 framework. First identified by Rapid7 in February 2025, the campaign utilizes a sophisticated multi-stage loader called Catena, which operates entirely in memory to evade traditional antivirus detection. The malware, attributed to a threat actor known as Silver Fox, specifically targets Chinese-speaking environments and has been active throughout 2025, adapting its tactics to maintain persistence and avoid detection. The campaign leverages trojanized NSIS installers and is characterized by its careful planning and execution.
