A large-scale malware campaign has been found leveraging a vulnerable Windows driver associated with Adlice's product suite to sidestep detection efforts and deliver the Gh0st RAT malware . "To further evade detection, the attackers deliberately generated multiple variants (with different hashes) of the 2.0.2 driver by modifying specific PE parts while keeping the signature valid," Check Point said in a new report published Monday. The cybersecurity company said the malicious activity involved thousands of first-stage malicious samples that are used to deploy a program capable of terminating endpoint detection and response (EDR) software by means of what's called a bring your own vulnerable driver ( BYOVD ) attack.
