The threat resides in the chips' data memory-dependent prefetcher, a hardware optimization that predicts the memory addresses of data that running code is likely to access in the near future. The breakthrough of the new research is that it exposes a previously overlooked behavior of DMPs in Apple silicon: Sometimes they confuse memory content, such as key material, with the pointer value that is used to load other data.

Attackers are leveraging a vulnerability in Anyscale's Ray AI software to compromise enterprise servers and saddle them with cryptominers and reverse shells."We observed hundreds of compromised clusters in the past three weeks alone. Each cluster uses a public IP address, and most clusters contain hundreds to thousands of servers. There are hundreds of servers that are still vulnerable and exposed."
The technique is a collection of security vulnerabilities that would allow a hacker to almost instantly open several models of Saflok-brand RFID-based keycard locks sold by the Swiss lock maker Dormakaba. By exploiting weaknesses in both Dormakaba's encryption and the underlying RFID system Dormakaba uses, known as MIFARE Classic, Carroll and Wouters have demonstrated just how easily they can open a Saflok keycard lock.
Cybersecurity researchers are warning that threat actors are actively exploiting a "disputed" and unpatched vulnerability in an open-source artificial intelligence (AI) platform called Anyscale...
The newly exposed GoFetch vulnerability affecting Apple's M1, M2 and M3 chips lets an attacker exfiltrate secret keys from cryptographic applications on a targeted system. DMPs - in contrast to classical prefetchers that only store the memory access pattern - "Also take into account the contents of data memory directly to determine what to prefetch," as written in the publication from Boru Chen, Yingchen Wang, Pradyumna Shome, Christopher W. Fletcher, David Kohlbrenner, Riccardo Paccagnella and Daniel Genkin that reveals all of the details about the GoFetch vulnerability.
A new security shortcoming discovered in Apple M-series chips could be exploited to extract secret keys used during cryptographic operations. Dubbed GoFetch, the vulnerability relates to a...

NIST's NVD has encountered a problemWhether the cause is insurmountable technical debt, lack of funds, a third reason or all of them, NIST's National Vulnerability Database is struggling, and it's affecting vulnerability management efforts.
Apple is having its own Meltdown/Spectre moment with a new side-channel vulnerability found in the architecture of Apple Silicon processors that gives malicious apps the ability to extract cryptographic keys. "We reverse-engineered DMPs on Apple m-series CPUs and found that the DMP activates data loaded from memory that 'looks like' a pointer," the team say in the paper.
