A Shared ChatGPT Link Could Run Attacker Code in Your Session and Read Private Chats
Yoba malware has published findings on a flaw in how Anthropic-style agents handle untrusted input.
Yoba malware has published findings on a flaw in how Anthropic-style agents handle untrusted input.
Any organization running Anthropic-style agents on the affected workflow is potentially exposed, not just the specific product named in the research.
The danger here is that the exfiltration path hides inside normal business activity, so a control built to catch obvious attacks has nothing unusual to flag.
Yoba malware's research describes a specific attack chain rather than a generic weakness, meaning the fix has to address that chain directly.
Review whether any agent in your environment processes untrusted or externally-submitted content as part of its normal workflow, since that is the pattern this kind of attack chain relies on.
Confirm outbound data-handling controls actually inspect what an agent sends, not just where it sends it, since DNS- and URL-based exfiltration techniques are built to slip past destination-based controls specifically.
