Apple Encryption Key Out in the Open Due to a New Vulnerability

The Apple M-series faces an exploitable vulnerability that could reveal keys used during cryptographic operations. According to reports, the vulnerability tagged GoFetch is associated with a microarchitectural side-channel attack leveraging data memory-dependent prefetcher (DMP) to target constant-time cryptographic implementations and capture sensitive data from the CPU cache. Further information about DMP by a team comprising of the University of Illinois Urbana-Champaign, University of Texas, Georgia Institute of Technology, University of California, Berkeley, University of Washington, and Carnegie Mellon University revealed that “DMP activates (and attempts to dereference) data loaded from memory that ‘looks like’ a pointer. This explicitly violates a requirement of the constant-time programming paradigm, which forbids mixing data and memory access patterns.”

MuddyWater has Deployed Atera Surveillance in Phishing Attacks.

An intelligence report from Proofpoint has linked MuddyWater, an Iran-affiliated threat actor also known as Mango Sandstorm or TA450, to a new phishing campaign targeting Israeli entities in sectors including manufacturing, technology, and information security to deliver Atera, which is a Remote Monitoring and Management (RMM) solution. A report by the company about the situation states

“TA450 sent emails with PDF attachments that contained malicious links. While this method is not foreign to TA450, the threat actor has more recently relied on including malicious links directly in email message bodies instead of adding this extra step.” Reports revealed the latest attack trend involves MuddyWater embedding links to files hosted on file-sharing sites such as Egnyte, Onehub, Sync, and TeraBox.
