July 2026: COLDCARD firmware generated weak seeds

A firmware build setting introduced in 2021 made COLDCARD devices generate seeds with a software random number generator instead of the hardware one. According to Coinkite, seeds created on the Mk4, Mk5 and Q carry about 72 bits of entropy rather than 128, and older Mk2/Mk3 firmware fared worse. Attackers began guessing and sweeping affected wallets on 30 July 2026; Galaxy Research confirmed more than 1,778 BTC stolen. Coinkite states the devices themselves were not hacked or remotely accessed.

Affected: seeds generated on Mk4/Mk5 firmware before 5.6.0, Q firmware before 1.5.0Q, Edge firmware before 6.6.0X / 6.6.0QX, and Mk2/Mk3 firmware 4.0.1–4.1.9. Seeds built from 50 or more private dice rolls are not at risk from this bug.

What Coinkite advises:

  • Install the fixed firmware before generating a new seed.
  • Move funds to a newly generated seed, even if you use a strong passphrase — updating firmware does not repair an existing seed.
  • Verify the new backup and a receive address on the device, send a small test transaction, then move the rest.

Current firmware is fixed; the risk remains for funds still held on seeds made with the affected versions.
