Teams that deploy AI agents to read email and pass messages to finance staff could be exposed to this kind of hidden instruction. Those teams should check how their agents handle instructions embedded in message content. The finding shows that a message can look harmless to people while carrying commands aimed at automated readers.

Security-conscious readers may want to review the source and watch for practical exposure or mitigation details.
