Hackers have been exploiting a previously legitimate EnCase kernel driver, which had been revoked, to create a tool that targets endpoint detection and response (EDR) solutions. This EDR killer can identify and disable 59 different security products, putting organizations at significant risk. The use of a signed driver adds a layer of legitimacy to the attack, making it harder for security systems to detect the malicious activity. This incident raises concerns for companies relying on these security tools, as attackers can effectively bypass defenses and compromise systems. It's crucial for organizations to be aware of this tactic and take steps to reinforce their security measures against such threats.
