"They will use the latest tools to figure out where they might have a vulnerability and where there isn't a patch that is already available," Krishna said. IBM shares climbed following the announcement.

Krishna noted that large language models generally are "remarkably adept at finding vulnerabilities" and exploiting issues in proprietary and open-source code. Despite multiple meetings to discuss a path forward, leaders have yet to announce a cohesive strategy on how to respond to the cyber threats posed by Anthropic's latest model. As part of its open-source push, IBM and Red Hat are dedicating 20,000 software engineers to help partners secure software. …
