Bitcoin self-custody<\/strong>, long considered the ultimate shield against exchange hacks, is now firmly in the crosshairs of attackers. A major incident involving Coldcard<\/strong> wallets is sending shockwaves through the crypto community.<\/p>\n\n\n\n

Potential losses are now approaching $114 million<\/strong> \u2014 and artificial intelligence<\/strong> is believed to be at the core of the attack mechanism. This is a warning signal that is impossible to ignore.<\/p>\n\n\n\n

Here is a full breakdown of a threat that is redefining security standards for Bitcoin<\/a><\/strong> self-custody holders.<\/p>\n\n\n\n

Coldcard Under Fire: How Did the Attack Work?<\/h2>\n\n\n\n

Coldcard<\/strong> is one of the most respected hardware wallets<\/strong> in the Bitcoin ecosystem, favored by advanced users for its robustness and air-gapped architecture. Yet the ongoing incident demonstrates that no device is entirely immune to sophisticated attacks.<\/p>\n\n\n\n

Based on the information available so far, the attack does not directly target the wallet’s firmware. Instead, it exploits peripheral vectors \u2014 potentially linked to supply chain<\/strong> attacks, compromised seed phrases<\/strong>, or third-party management interfaces. The involvement of AI<\/strong> in this attack vector marks a clear turning point: generative tools now make it possible to craft hyper-personalized phishing<\/strong> campaigns, simulate legitimate interfaces with unsettling precision, and automate large-scale attacks against specific targets.<\/p>\n\n\n\n

Exposed funds are estimated at close to $114 million in Bitcoin<\/a><\/strong>, according to data aggregated by on-chain security researchers. This figure places the incident among the most significant non-custodial wallet<\/strong> compromises of 2025.<\/p>\n\n\n\n

AI \u2014 The New Offensive Weapon Against Crypto: What It Really Changes<\/h2>\n\n\n\n

The use of artificial intelligence<\/strong> in crypto cyberattacks is no longer a theoretical scenario. Recent reports from firms such as Chainalysis<\/strong> and CertiK<\/strong> document a sharp rise in AI-powered tools within hackers’ arsenals: fake exchange websites, audio and video deepfakes<\/strong> impersonating legitimate projects, and now precise targeting of hardware wallet holders.<\/p>\n\n\n\n

In the Coldcard<\/strong> case, AI is believed to have industrialized social engineering<\/strong> \u2014 automatically identifying high-net-worth crypto profiles across social media, specialized forums, and leaked databases, then delivering perfectly calibrated fraudulent communications to those targets. This level of personalization was previously reserved for state-sponsored APT (Advanced Persistent Threat)<\/strong> attacks.<\/p>\n\n\n\n

For Bitcoin<\/strong> self-custody holders, the implications are immediate and direct:<\/p>\n\n\n\n
