Coldcard Hackers Prioritize High-Value Wallets in Rapid $30M Heist

Woofun AI reports that a sophisticated breach of Coldcard wallets resulted in the rapid exfiltration of $30 million, with attackers strategically prioritizing high-value accounts to maximize immediate gains. This targeted approach underscores a shift toward precision-based theft rather than broad, indiscriminate draining.

The operation unfolded with alarming speed, as automated tools identified and siphoned $30 million within the first 10 minutes, continuing the extraction process for an additional 25 minutes.

Woofun AI data shows the exploit likely stemmed from a vulnerability in Coldcard firmware or a supply chain compromise, enabling remote access to devices previously considered secure against such threats. The efficiency of the attack highlights the reliance on automated scripts to bypass security protocols before defensive measures could be activated.

Post-exfiltration, the perpetrators employed complex laundering techniques, routing stolen funds through mixing services and cross-chain bridges to obscure transaction trails and hinder recovery efforts. This tactic challenges the traditional assumption that hardware wallet users are immune to remote theft, revealing significant gaps in current security paradigms. The incident emphasizes the critical need for multi-signature setups and diversified cold storage solutions to protect large holdings from single-point failures.

Coldcard has issued a critical patch, urging affected users to update their devices immediately and transfer assets to new wallets if compromise is suspected. This event marks a significant escalation in data-driven heists, requiring enhanced law enforcement coordination and robust regulatory responses to combat evolving cybercrime tactics. The breach serves as a stark reminder that no single security measure is foolproof in the face of increasingly sophisticated attacks.
