In April 2026, a financially motivated campaign distributed the Vidar stealer and XMRig cryptocurrency miner via malvertising, targeting users searching for cracked software. The attackers used password-protected archives with fake code signing certificates to evade detection and deliver payloads. The malware employed file inflation, DLL sideloading, and AMSI bypass techniques to avoid sandbox analysis and security controls. Victims were primarily located in the U.S. and EU, with data exfiltrated to C2 servers and Monero mining initiated through a configured pool.
