G7 urges organizations to prepare for quantum cyber threats
G7 Cyber Security Working Group and CISA jointly urge organizations to begin migrating to post-quantum cryptography now, citing harvest-now-decrypt-later risk.
In a joint advisory, the G7 Cyber Security Working Group and CISA recommend starting post-quantum cryptography migration immediately rather than waiting for quantum computers to break current encryption. They warn attackers can already harvest encrypted data for later decryption, threatening long-lived secrets such as government records and trade secrets. Organizations are told to inventory sensitive systems, prioritize them, and fold quantum-resistant upgrades into routine refresh cycles. The advisory follows a UK 2035 PQC roadmap and recent US executive orders on quantum preparedness.

NIST and CISA finalize playbook to stop token theft and forgery
NIST and CISA finalized NIST IR 8587, a playbook helping federal agencies and cloud providers defend identity tokens against theft and forgery.
The finalized NIST IR 8587 guidance covers protecting token signing keys, verifying tokens, lifetimes, revocation, session management, and dividing security responsibilities between cloud providers and customers. It cites an incident in which foreign actors forged tokens with a stolen commercial signing key to steal more than 60,000 emails from one government agency. It also recommends extending token protections to AI agents and preparing identity systems for a future post-quantum cryptography transition.

CISA and NIST Release Technical Checklist for Safeguarding Identity Tokens From Theft and Misuse
CISA and NIST published NIST IR 8587, final guidance for protecting identity tokens from forgery, theft, replay, and signing-key compromise.
NIST Interagency Report 8587 (September 15, 2026) expands the IA-13 'Identity Providers and Authorization Servers' control from NIST SP 800-53 R5.1.1, guiding federal agencies and cloud providers on SSO, identity federation, and machine-to-machine authentication. It requires hardware-backed signing-key storage for moderate-impact systems, 90-day key rotation for high-impact systems, token lifetimes under one hour, and sender-constrained mechanisms such as mutual TLS and DPoP. The report cites incidents including forged SAML assertions that exposed over 60,000 emails from a federal agency. It also extends guidance to agentic AI systems using signed tokens and urges post-quantum cryptography migration planning.
