The Warlock ransomware campaign is using SharePoint vulnerabilities to break into a water utility, telecom provider, regional government body, and university across Europe, Africa, and Latin America. The group emerged in June 2025 and has been active over the past two months, with ToolShell zero-days helping open the door. In a July 22 intrusion, attackers disabled protection on at least 40 hosts and then launched ransomware on at least 33 hosts. Continued exploitation of SharePoint keeps exposed on-premises deployments at risk of follow-on intrusion and extortion.

Warlock ransomware was launched on at least 33 hosts after protection was disabled, compressing the final stage of the intrusion into a rapid network-wide rollout. The deployment followed an AV/EDR-killing tool that turned off defenses on compromised machines. The payload was staged in SYSVOL, enabling broad execution across the environment.

Antino is being deployed as a Windows backdoor that gives operators host reconnaissance, command execution, file transfer, and persistence while routing C2 through Microsoft 365 dead drops, increasing stealth against defenders.

A UAT-11587 spear-phishing campaign is expanding across Asia and Syria, delivering the Antino backdoor to government and policy organizations and increasing the risk of espionage and persistent access. The operation first surfaced in September 2025 and later broadened to targets in Taiwan, India, the Philippines, Cambodia, Pakistan, Thailand, Myanmar, and Syria. It uses tailored lures, spoofed trusted senders, and a fake Gmail attachment preview to push victims into a multi-stage infection chain. Antino then abuses Microsoft 365, especially Outlook and OneDrive, for command-and-control and file transfer.
