Cyberthreat Intelligence Report: May 2026

What's Inside

Critical Cyber News

A roundup of the month's most consequential incidents, including TeamPCP's gamified supply-chain bounty program and the 3,800-repository GitHub breach to the Foxconn ransomware attack and Sandworm's pivot into critical OT systems.

Vulnerability Spotlight

A deep dive into the most severe Linux local privilege-escalation flaw in years. “Copy Fail” corrupts page-cache-backed memory to reach root while leaving the on-disk file untouched — stealthier than Dirty COW and already in CISA's KEV catalog. Includes the full exploitation chain and mitigation guidance.

Malware Deep Dives

Static, dynamic, and MITRE ATT&CK analysis of three emerging threats: the Go-based M3RX ransomware, the heavily evasive Evelyn infostealer, and the multi-platform Aur0ra ransomware — plus how Cynet's unified platform detects and prevents each one.

This report is produced by Cynet's CyOps Threat Intelligence Team, combining decades of combined expertise and continuous threat research, real-world telemetry, and hands-on incident response experience to deliver intelligence that is timely, relevant, and designed for action.
