๐Ÿ‘พ#Crypto Hackers have stolen 594 BTC from Coldcard Mk3 hardware wallets. On July 30, around 594.5 BTC (roughly $38 million) was drained from about 500 wallets. Every affected address was single-sig โ€” no multisig or Taproot wallets were involved. Seed phrases generated on Mk3 devices running firmware 4.0.1โ€“5.0.3 (released since March 2021) may be compromised due to weak entropy (around 72 bits instead of 128+). In some cases, the random number generator skipped the hardware TRNG and relied on predictable inputs, including button presses during setup. This allowed attackers to reconstruct private keys offline.
