AI is also emerging as a growing threat to crypto companies, giving attackers tools to find vulnerabilities faster, automate attacks and make phishing and social-engineering campaigns more convincing. That raises the stakes for an industry already a frequent target for hackers, while fueling a race to deploy the same technology on the defensive side.
Claude Mythos 5 is Anthropic’s most advanced model for defensive cybersecurity, designed to analyze code at scale, identify vulnerabilities and help developers fix them. Access has initially been limited to organizations that operate or defend critical infrastructure, as Anthropic works on safeguards for a broader rollout.
Payward argued that crypto platforms face security challenges similar to other critical financial infrastructure. Exchanges, custody systems and settlement rails operate around the clock and can present lucrative targets for attackers.
“Security has always been an unfair game. An attacker needs to find one flaw. A defender has to find all of them, first, every single day,” Payward co-CEO Arjun Sethi said in the release. “Frontier AI is the first thing that flips that asymmetry.”
Anthropic has said it plans to expand access to Mythos-class cybersecurity capabilities as it develops safeguards for wider use.
