CPU microcode hack could infect processors with ransomware directly

A researcher created a working PoC for a ransomware strain that bypasses all antivirus programs.

Ransomware can now run directly on the CPU, researcher warns

A security researcher designed a way to "weaponize" microcode updates to install ransomware directly onto the CPU. Rapid7 analyst Christiaan Beek drew inspiration from a critical flaw in AMD's Zen processors, discovered by Google researchers earlier this year. The flaw could allow attackers to modify the RDRAND instruction and inject...Read Entire Article

Now ransomware starts infecting Central Processing Units aka CPUs - Cybersecurity Insiders

AI is evolving at a rapid pace, and the uptake of Generative AI (GenAI) is revolutionising the way humans interact and leverage this technology. GenAI is

Researchers have demonstrated a proof-of-concept ransomware that can run at the CPU level, injecting malicious microcode to change processor behavior by exploiting AMD chip vulnerabilities. This attack can bypass existing security measures. Although the risk is currently low, we need to be vigilant about possible threats in the future. Experts point out that the foundation of cybersecurity still needs to be strengthened.
