Factoring RSA Keys with Many Zeros

A collection of security-relevant items from Schneier’s blog: researchers (badkeys) found many real-world RSA moduli with unusually sparse (many-zero) bit patterns and described new polynomial-based factoring attacks against such keys, exposing a class of weak RSA keys in the wild. A separate high-impact data breach exposed nearly one million passports online, illustrating how high-value credentials can be compromised via weaker ancillary systems. Malware authors are embedding policy-triggering/forbidden text (e.g., nuclear/bioweapons content) inside harmless code comments to cause AI-assisted
