When the recipient requested a summary, the payload attempted to make the assistant append a fabricated security warning.<\/p>\n<p>The consequence described is social engineering: a user might trust the assistant\u2019s summary more than the untrusted message that influenced it. An instruction rendered invisibly in the email can still be available to the model.<\/p>\n<p>Treat unexpected account warnings in generated summaries as unverified. Check security notifications through the service\u2019s known interface rather than a phone number or link supplied by the summary.
