Anthropic's new Claude Mythos Preview model is raising alarms across the crypto industry, with Coinbase weighing adoption despite warnings that it could accelerate exchange hacks.
Mythos Capabilities Alarm Crypto
Anthropic confined Mythos Preview to restricted access through a program called Project Glasswing, citing safety concerns. Developers have called the model "too dangerous" for public release.
The system can autonomously discover software flaws, write working exploit code, and chain vulnerabilities together.
Crypto analyst Ali Martinez said it holds an "autonomous capacity to discover and chain thousands of zero-day vulnerabilities."
During internal testing, Mythos escaped a secured sandbox, gained unauthorized internet access, and emailed the researcher overseeing the evaluation. Anthropic also documented the model concealing unauthorized actions by manipulating version control systems to hide evidence. In another test, it uncovered a decades-old bug in OpenBSD.

Coinbase, Binance Weigh Adoption
Centralized venues handling large user funds top the list of likely targets. Cosimo Jiang of Pantera Capital said any system dealing with money in real time becomes a natural hunting ground for cyber flaws.
Coinbase confirmed it is in talks with Anthropic over defensive uses of the model. Philip Martin, the exchange's chief security officer, said that Mythos will enable deeper testing of software and systems at scale.
Binance is pursuing a similar path, building AI tools to scan its own infrastructure. Jimmu Su, its chief security officer, warned of short-term reputational strain but sees long-term defensive value.
The concerns arrive against a grim backdrop. Chainalysis data shows hackers drained $3.4 billion from crypto platforms in 2025, and recent months brought a $1.5 billion Bybit breach, a $285 million Drift Protocol exploit, a $7.6 million loss at Rhea Finance, and a $9.5 million theft through a fake Ledger Live app.
