A critical code-execution vulnerability in Microsoft Windows was patched in September. It seems that researchers just realized how serious it was (and is): Like EternalBlue, CVE-2022-37958, as the latest vulnerability is tracked, allows attackers to execute malicious code with no authentication required. Also, like EternalBlue, it’s wormable, meaning that a single exploit can trigger a … Read More “Critical Microsoft Code-Execution Vulnerability” »

The attack requires physical access to the computer, but it’s pretty devastating: On Thunderbolt-enabled Windows or Linux PCs manufactured before 2019, his technique can bypass the login screen of a sleeping or locked computer — and even its hard disk encryption — to gain full access to the computer’s data. And while his attack in … Read More “Attack Against PC Thunderbolt Port” »
Yesterday’s Microsoft Windows patches included a fix for a critical vulnerability in the system’s crypto library. A spoofing vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates. An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was … Read More “Critical Windows Vulnerability Discovered by NSA” »
China is being blamed for a massive surveillance operation that targeted Uyghur Muslims. This story broke in waves, the first wave being about the iPhone.
