De multiples vulnérabilités ont été découvertes dans les produits Juniper Networks. Certaines d'entre elles permettent à un attaquant de provoquer une exécution de code arbitraire, une élévation de privilèges et un déni de service à distance.

Posted by David Adrian, David Benjamin, Bob Beck & Devon O'Brien, Chrome Team We previously posted about experimenting with a hybrid post-quantum key exchange, and enabling it for 100% of Chrome Desktop clients. The hybrid key exchange used both the pre-quantum X25519 algorithm, and the new post-quantum algorithm Kyber. At the time, the NIST standardization process for Kyber had not yet finished. Since then, the Kyber algorithm has been standardized with minor technical changes and renamed to the Module Lattice Key Encapsulation Mechanism (ML-KEM). We have implemented ML-KEM in Google’s cryptography library, BoringSSL, which allows for it to be deployed and utilized by services that depend on this library. The changes to the final version of ML-KEM make it incompatible with the previously deployed version of Kyber. As a result,…

A cyberattack that shut down two of the top casinos in Las Vegas last year quickly became one of the most riveting security stories of 2023. It was the first known case of native English-speaking hackers in the United States and Britain teaming up with ransomware gangs based in Russia. But that made-for-Hollywood narrative has eclipsed a far more hideous trend: Many of these young, Western cybercriminals are also members of fast-growing online groups that exist solely to bully, stalk, harass and extort vulnerable teens into physically harming themselves and others.

In September 2023, a Russian ransomware group known as ALPHV/Black Cat claimed credit for an intrusion at the MGM Resorts hotel chain that quickly brought MGM’s casinos in Las Vegas to a standstill. While MGM was still…
