Chypothermia: Clock Freezing for Static Side-channel Attacks

Chypothermia attack uses cryogenic cooling to disable clock and voltage sensors, evading detection and blocking key zeroization on OpenTitan root of trust.

Chypothermia is a static side-channel attack that exposes chips to cryogenic temperatures, disrupting on-chip mixed-signal components to disable the clock sensor, clock generation circuit, and voltage sensors without electrical tampering. Combined with Chypnosis (IEEE S&P 2026), it halts the clock while evading temperature-based anomaly detection. It was implemented on multiple FPGA/SoC platforms and applied to the OpenTitan root of trust's alert handler, evading detection and preventing key zeroization. The authors also propose an FPGA-compatible self-heating sensor as a countermeasure.

Doctor Doom Thanked Seattle for All the Surveillance Cameras

Activist dressed as Doctor Doom urged Seattle's council to curb Axon and Flock surveillance after a committee voted to redirect $250,000 from CCTV expansion.

Clifford Cawthon, a policy advisor at the Washington State Department of Commerce, appeared at a Seattle Public Safety Committee meeting in costume as Doctor Doom to protest the city's expanding mass surveillance. He criticized Seattle PD's access to 62 cameras feeding an Axon real-time crime center that ingests CCTV, body camera, geolocation, ALPR, and dispatch data from vendors like Axon and Flock. His group Community Not Cameras submitted a petition with five demands, and a committee already voted to move $250,000 away from CCTV expansion pending full council approval.

Stop Telling People Not To Click Links

Tailscale CEO argues link-clicking is not the problem; deploying phishing-resistant authentication like passkeys and WebAuthn eliminates entire attack classes.

Tailscale CEO Avery Pennarun argues in an opinion piece that clicking links is a symptom, not the disease, and that weak authentication is the real failure behind phishing damage. He advocates phishing-resistant FIDO/WebAuthn, passkeys, and device-bound tokens, plus continuous identity-anchored network access so unexpected login prompts become suspicious signals. He argues this approach makes security less burdensome for users while neutralizing credential replay and fake login pages.
