2Hackers are laundering the stolen funds through mixing services after exploiting a firmware vulnerability.

Amid escalating concerns over digital asset security, technical reports have revealed a significant increase in funds stolen due to a vulnerability in Coldcard hardware wallets. According to reports, total losses stemming from the firmware exploit have surpassed $130 million in Bitcoin. Hackers are currently laundering these funds through cryptocurrency mixing services, complicating efforts to track and recover the stolen assets in what marks one of the largest theft incidents of 2026.

Analytical data indicates that the vulnerability allowed attackers to compromise wallet security without requiring physical access to the devices, impacting thousands of individual users. Per market analysis, this breach stands as the third-largest crypto theft this year, with stolen funds being traced to privacy-focused platforms such as Tornado Cash and Wasabi to obscure the attackers' identities.

Investors should watch for official firmware patches from Coldcard and monitor broader economic catalysts, such as the recent inflation data from the EU and US, which continue to influence general risk appetite across the digital asset sector.
