If you use virtual machines, there's reason to feel less-than-Zen about AMD's CPUs. Computer scientists affiliated with the CISPA Helmholtz Center for Information Security in Germany have found a ...

A new software-based fault injection attack, CacheWarp, can let threat actors hack into AMD SEV-protected virtual machines by targeting memory writes to escalate privileges and gain remote code ...

CISPA researchers have published technical details on “StackWarp,” a vulnerability that undermines integrity guarantees for Confidential Virtual Machines built on AMD SEV-SNP. The affected scope ...

Researchers have developed an exploit for AMD CPUs that allows attackers to undermine memory protections, and thereby escalate privileges or perform remote code execution (RCE) in cloud environments.

One of the oldest maxims in hacking is that once an attacker has physical access to a device, it’s game over for its security. The basis is sound. It doesn’t matter how locked down a phone, computer, ...

CISPA researcher Ruiyi Zhang and colleagues have discovered a new security flaw that can threaten the integrity of Confidential Virtual Machines (CVMs) running on AMD CPUs from the Zen-1 through Zen-5 ...
