Top Tech Expert Joins Anthropic to Boost AI Security

Sam Blackshear, co-founder and chief technology officer of Mysten Labs, is leaving to join Anthropic and focus on defensive security research, citing the shift in power between attackers and defenders due to AI. As AI increasingly identifies software vulnerabilities and automates attacks on blockchain infrastructure, Blackshear’s move highlights the growing importance of AI security. This change comes as the balance of power between attackers and defenders is shifting, making it a critical time for experts like Blackshear to work on security. With his expertise, Anthropic aims to strengthen its AI security capabilities.

Blackshear co-founded Mysten Labs, the creator of the Sui blockchain, in 2021 with four former Meta executives. He will be succeeded by Mysten Labs co-founder and CEO Evan Cheng, who will set the technical vision for the company going forward. Blackshear’s departure does not mark the end of his involvement with Mysten, as he will remain a close advisor and stay involved in the Move Foundation. His move to Anthropic demonstrates the increasing need for experts in AI security to protect against growing threats.
