Researchers have identified a new exploit impacting upcoming processors called “Spectre based on Linear Address Masking” (SLAM). This side-channel-based attack exploits the new security features in Intel (Linear Address Masking (LAM)), AMD (Upper Address Ignore (UAI)), and ARM (Top Byte Ignore (TBI) chips. Specifically, the SLAM attack is a transient execution technique exploiting the new memory improvement features to leak sensitive data like password hashes.

"Variants of CL0p were initially only found on Windows systems, but the gang also developed a Linux variant toward the end of 2022, reflecting the diversity of endpoint operating systems used by modern businesses. In an interesting, flawed technical glitch, security researchers noted that the Linux version’s encryption is easily reversible using a simple decryptor."
