Some custom malware, some legit software tools At least a dozen ransomware gangs have incorporated kernel-level EDR killers into their malware arsenal, allowing them to bypass almost every major endpoint security tool on the market, escalate privileges, and ultimately steal and encrypt data before extorting victims into paying a ransom.…

Until recently, the cyber attacker methodology behind the biggest breaches of the last decade or so has been pretty consistent: Compromise an endpoint via software exploit, or social engineering a user to run malware on their device;  Find ways to move laterally inside the network and compromise privileged identities; Repeat as needed until you can execute your desired attack — usually

Secure enterprise browsers deliver multi-layered security, including web security, protection against malware on the endpoint, and defense against malicious extensions.

A threat actor known as Hazy Hawk has been observed hijacking abandoned cloud resources of high-profile organizations, including Amazon S3 buckets and Microsoft Azure endpoints, by leveraging misconfigurations in the Domain Name System (DNS) records

Google dumped io_uring after $1M in bug bounties A proof-of-concept program has been released to demonstrate a so-called monitoring "blind spot" in how some Linux antivirus and other endpoint protection tools use the kernel's io_uring interface.…
