Over $100M US in Bitcoin Stolen in Coldcard Hack

LinkCBC NewsNews

According to a CBC News report citing blockchain intelligence firm Galaxy Research, hackers have drained over $100 million US worth of bitcoin from Coldcard hardware wallets.

Key points

  1. Hackers stole more than $100 million US worth of bitcoin from Coldcard wallets.
  2. The theft was reported by blockchain intelligence firm Galaxy Research.
  3. Coldcard is produced by Toronto-based Coinkite as an offline cold-storage solution.
  4. The device was widely regarded by users and security specialists as one of the safest ways to store bitcoin.
  5. The perpetrators behind the attack remain unknown.

Why it matters

Cold-storage hardware wallets represent the industry standard for keeping crypto keys completely offline. A breach of this scale involving a widely trusted vendor challenges common assumptions about hardware wallet security.

Analysis

The source does not detail the technical exploit mechanism—such as whether the drain resulted from firmware vulnerabilities, supply-chain tampering, or compromised seed generation. Because Coldcard is designed explicitly for air-gapped operations, the incident underscores that even reputable offline storage setups require ongoing scrutiny.

    Quantum Vulnerabilities in Cryptocurrencies: Resource Estimates and Mitigations

    A research team including Ryan Babbush, Justin Drake, and Dan Boneh presents updated resource estimates for breaking 256-bit elliptic curve cryptography on quantum hardware. Shor's algorithm can solve the 256-bit Elliptic Curve Discrete Logarithm Problem using <1200 logical qubits and <90 million Toffoli gates, or <1450 logical qubits and <70 million Toffoli gates. On superconducting architectures, this could execute in minutes using fewer than 500,000 physical qubits.
