EDR-Killers Increasingly Used to Bypass Security in Ransomware Operations

Ransomware groups are increasingly adopting specialized "EDR-killer" tools and techniques—including exploitation of vulnerable Windows drivers, rootkits, universal unhooking, and the misuse of legitimate monitoring software (e.g., HRSword)—to disable or evade endpoint detection and response (EDR) systems, enabling undetected data theft, lateral movement (NetSupport RAT, Smbexec), and more effective ransomware deployments; the report cites incidents involving RansomHub, GlobeImposter, and Phobos and stresses the critical need for early detection and blocking of these tools.
