Guarding the CBOM: The Most Sensitive Document Your Security Program Produces
Cryptographic discovery finds weaknesses that matter today, not only after a quantum computer. The resulting inventory ranks them, stays useful to attackers for years, and almost nobody has said to guard it.

When Two Cryptographers Independently Confirm a Break, Ask Which Model They Used
Two proofs of the same result landed three hours apart from the same model, and Simon's DCP claim is now being taken apart by humans and models working together. Separate names no longer establish separate failure modes.

Two QFT Records in Four Months. Neither Gets You Closer to Breaking RSA.
Two compilation teams claimed the largest quantum Fourier transform ever run, four months apart, on the same IBM chip. Their circuits and metrics are not comparable, and the gate counts explain why.

AI Hacking Theater and the Crypto-Agility Wake-Up Call
OpenAI and Anthropic spent two weeks one-upping each other's AI hacking disclosures. Buried beneath the competitive theater are three developments CISOs can no longer ignore, and the defense for all three is the same.

AI Can Hack Everything? Do the Math First
Everyone is selling protection from AI hackers. Almost nobody is asking whether AI attacks can actually scale, or whether the answer was sitting in their security budget the whole time.
