Juliano Rizzo posts the line "Introduced in 2014, wallet drain exploit detected in 2026:" over a screenshot of a discussion dated 25 April 2014, addressed to @daviddahl, about JavaScript entropy: it offers a custom generator built on Knuth's linear congruential PRNG, seeded in part from Math.random, and closes by noting the result is still predictable if you control all the parameters. The post names neither the library nor the 2026 drain it has in mind, and the code shown is JavaScript library code rather than COLDCARD firmware. Held because a security researcher is dating a second, separate entropy failure to 2014 and tying it to a 2026 drain, a parallel MAGS draws explicitly a few hours later at crypto_mags-2085586783803453912. The identification and the connection are the poster's own and are not verified here.
This post is registered as evidence and has a locally held capture. The original remains the canonical publication. Last checked .
This post is held twice: here, with this project's own note on why it matters, and again as part of the conversation captured at , which is polled for changes. Both copies are the same post; neither is a separate event.
Snapshot and diff bodies for this chain monitor are held in the local evidence archive but withheld from the public site because they can contain the addresses of people who published nothing themselves. Capture times and reviewed change summaries remain available below.
