Summary

Hide ▲

The Winos 4.0 malware operation has expanded its target footprint to Japan and Malaysia through HoldingHands RAT, increasing the reach of a multi-stage phishing delivery chain. The malware can connect to remote servers, receive attacker-issued commands, and capture sensitive information, making the infections more dangerous. The activity continues to rely on phishing PDFs, malicious links, and fake landing pages to seed compromise. The broadened targeting raises the risk of follow-on theft and additional payload delivery.
