Interesting approach of using a fault-tolerance feature to handle transient HW issues as a way to bypass fingerprint attempt counters. Obviously less practical due to needing invasive physical access and a fingerprint database, but a nice multi-device logic bug class!

Heard about this on @riskybusiness@infosec.exchange and @casey thought it would be a good one to read as a #ThinkstScapes candidate.

A breakthrough if it withstands scrutiny
5 stars
This paper (and the associated code/service: timevault.drand.love/) may be one of the most/only valuable contributions to come from the entire web3 ecosystem. The ability to commit to a future decryption time is a powerful primitive, such as in auctions, coordinated disclosure, and other "dead man's switch" scenarios.
I look forward to this work being critiqued and built-upon for a whole host of interesting offerings.
Jacob T. wants to read An illusion of predictability in scientific results by Sam Zhang
Found this posted by @ct_bergstrom@fediscience.org as the "best paper I've read this year", which is a strong endorsement.
While an interesting modeling exercise, and certainly something to be worried about if you own or rely on a GEO satellite, the hostile takeover of an entire LEO constellation would be incredibly impactful beyond temporary jamming of a GEO bird.
High consequence junk hacking
2 stars
This paper predictably finds a lack of authentication and cryptographic protections in a legacy RF protocol that is designed to work around the world for life-saving signals. While they determine is it possible to spoof a signal in a lab environment, and call for improved authentication, etc. they fail to include the international legal framework surrounding these signals, and the fact that in a safety-critical environment, a signal discarded due to lack of nonce freshness is more risky than allowing bad actors with drones to send illegal signals.

Resurrecting stack-based overflows (yet again)
4 stars
This paper explored the weaknesses and risks associated with modern exception handlers (across all major OS and architectures) in unwinding attacker-controlled state. The most powerful example is a bypass of stack canaries where a function throws an exception after the overflow but before the function return; the exception handler would eventually execute attacker-controlled memory.
There is an attempt to quantify the overall impact of this mitigation bypass by looking at the Debian repos for code that uses exception handlers, but it is quite context sensitive. The paper concludes with three CVEs that would be exploitable with current mitigations (stack canaries, etc.) using the new technique.
