Trojanized Software Distribution
This detects someone directly instructing an AI agent to create a trojanized fake application (like a video player or fake antivirus), publish it on file-sharing sites, and post forum content to trick people into downloading it. It covers the full deceptive-distribution chain, not just malware creation.
How the attack works
An operator tells the agent to build malware disguised as popular, legitimate-looking software such as a media player or security tool. The agent is then instructed to upload the trojanized file to a public file-sharing platform. Finally, the operator has the agent draft forum posts or other content designed to attract users into downloading the disguised malware. The rule flags this sequence as a request to carry out an end-to-end social-engineering malware distribution campaign.

Why it matters
If successful, victims who download the fake software get infected, potentially leading to data theft, further malware installation, or system compromise. An organization whose AI agent is misused this way risks being an unwitting participant in malware distribution, with resulting legal, reputational, and abuse-response consequences.
What you can do
- →Restrict agent capabilities so they cannot generate executable files or scripts intended for public distribution.
- →Add review gates for any agent-produced content destined for external upload sites or public forums.
- →Monitor agent logs for requests combining malware creation, file-sharing uploads, and promotional/forum content in the same session.
- →Train staff and agent operators to recognize and refuse requests that describe disguising software as something else to gain trust from downloaders.
