594.48 BTC transferred in a consolidated move, Coinkite warns Coldcard Mk3 users to migrate funds

Odaily News: Canadian Bitcoin hardware manufacturer Coinkite has warned users of Coldcard Mk3 signing devices to migrate funds from wallets whose seed phrases were generated by affected firmware. Coinkite stated that seed phrases generated by Mk3 firmware version 4.0.1 and later, released in March 2021, may put funds at risk, with the impact extending to version 5.0.3, the final version supporting the Mk3. Coinkite said that Mk4, Q, and Mk5 models are not affected; affected users should generate new seed phrases on unaffected devices, verify backups and receiving addresses, send a small test transaction first, and then migrate the remaining funds. The company said its investigation is still ongoing and that a formal technical review will be published. Bitcoin security experts are examining a centralized transfer of unclear origin involving 594.48 BTC in single-signature addresses, valued at approximately $38.3 million. Rob Hamilton, CEO and co-founder of AnchorWatch, stated that 1,324 unspent transaction outputs were moved via 500 transactions within a three-block window, with 562 BTC subsequently consolidated into another address. Kevin Loaec, CEO of Wizardsardine, said the current hypothesis is that a low-entropy random number generator has caused insufficient randomness in some wallets' seed phrases, with the relevant flaw potentially stemming from a software library, secure element, specific device batch, or firmware version. He added that this hypothesis has not yet been confirmed, and wallets from which only partial funds were transferred may still face the risk of subsequent theft.
