As ransomware threats evolve, attackers have begun utilizing advanced malware known as "EDR killers" to effectively disable endpoint detection and response (EDR) tools. According to Cisco Talos, these tactics prove successful 48% of the time and are employed early during attacks, making it harder for organizations to recover. Ransomware crews leverage programs such as EDRSilencer and EDRKillShifter, which exploit vulnerabilities in legitimate drivers to execute their attacks. This rising trend significantly hampers detection and remediation efforts for compromised systems.
We're seeing this category of malware, EDR killers, and it's really evolving. And we're seeing... several different types of those tools in the same operation.
When ransomware actors attempted to do that, they were successful 48 percent of the time.
Especially in the ransomware space, system recovery is such an important part of the remediation process.
The goal is typically the same: kill EDR protections, allow the criminals to remain undetected for longer in the compromised networks.
