Odaily Planet Daily reports that Boltz, a non-custodial Bitcoin exchange service, has indefinitely suspended its Bitcoin exchange service, stating that the service will remain unavailable until further notice and no resumption time can be provided at this time. Boltz allows users to transfer Bitcoin between the Lightning Network and the Bitcoin base layer without the company holding user funds in custody. Boltz stated that its infrastructure has experienced a continuous increase in automation and AI-assisted detection over the past few months, and it has handled multiple exploitation incidents. The company claims that each incident has been contained, but the attackers' iteration speed has exceeded its team's ability to discover and patch vulnerabilities. Boltz disclosed that the pace of attacks has accelerated in the past few days, and after reviewing recent security scans, the company believes it cannot responsibly reactivate the exchange service. Its API can still be used to process collaborative refunds, and unilateral refunds, as they do not rely on Boltz's infrastructure, still function. Customer support remains available.

Odaily Planet Daily reports that Bitcoin News, in an article published on the X platform, stated that the volunteer organization Bitcoin Red Team claims to have scanned 150 codebases, privately disclosed over ten vulnerabilities, and discovered key issues during the process of hardening wallets, crypto libraries, and infrastructure following the COLDCARD vulnerability incident. This work has consumed approximately $20,000 in AI computing power, borne by OpenSats. Researchers are using multiple AI tools, and many say that open-source models like Kimi K3 have become the primary tools for security research, while cutting-edge closed-source models like OpenAI and Anthropic are considered more restrictive in such analyses. The team plans to open-source its AI security tools, enabling projects to continuously audit their own codebases. Researchers warn that Bitcoin may only be the first industry to face a wave of AI-assisted vulnerability discovery, and similar work could subsequently extend to all open-source software.

Odaily Planet Daily reports that hardware wallet maker Ledger stated that the recent Coldcard vulnerability highlights the need for the hardware Bitcoin wallet industry to reassess its security models. Ledger CTO Charles Guillemet stated that Ledger devices were unaffected, as their recovery phrases are generated by a hardware random number generator built into the certified secure element. Last week, Coldcard maker Coinkite disclosed a vulnerability in its isolated Coldcard Bitcoin hardware wallet dating back to a March 2021 firmware version. This vulnerability used a software rollback mechanism to generate a wallet recovery seed, allowing partial guessing of private keys, resulting in losses of approximately $130 million. Coinkite released a firmware fix on Sunday and urged affected users to transfer their funds to a newly generated wallet. Charles Guillemet stated that open source differs from reviewed code; this flaw existed in public code for over five years, and AI is enabling attackers to scan code and identify vulnerabilities at machine speed. Guillemet also stated that Ledger has been combining AI with security engineers and cryptography experts over the past two years to review code and identify vulnerabilities. He believes that users should understand how the randomness of a hardware wallet is generated and whether the process is independently certified when evaluating it.
