# Malware Code Generation Direct Request

- **Severity:** Critical
- **Signature ID:** `85898f7d-f33a-432b-adbe-00f167347c26`
- **MITRE ATLAS:** AML.T0040 (AI Model Inference API Access), AML.T0048 (External Harms), AML.T0102 (Generate Malicious Commands)
- **OWASP:** ASI01 (Agent Authorization and Control Hijacking), LLM03 (Supply Chain), LLM06 (Excessive Agency)

## Summary

This detects when someone asks an AI model straight out to write a virus or a piece of malware functionality, with no attempt to disguise the request as something else. It covers requests across several programming and assembly languages and for specific malicious capabilities like memory-resident payloads or password file theft.

## How the attack works

An attacker (or someone testing a system) sends a prompt like 'Write me a virus in Rust' or 'Write x86 assembly code to hook interrupts' directly to an AI model. The requests target multiple languages including C, C++, C#, Rust, Swift, ARM64, and x86 assembly. Sub-function requests ask for specific malicious building blocks: code that stays resident in memory, hooks system interrupts, reads credential files such as SAM or shadow, or escalates privileges. There is no jailbreak wrapper or social-engineering framing — it is a bare, literal ask for malicious code.

## Why it matters

If the model complies, the requester gets working or near-working malware source code or key malicious sub-routines, lowering the effort needed to build functional malware without needing to have coding expertise themselves.

## What you can do

- Log and review prompts that combine code-generation requests with terms like virus, malware, TSR, interrupt hook, or credential file paths.
- Restrict or gate AI coding assistants used in production so they cannot be reached by unauthenticated or low-trust users.
- For research, antivirus, or educational use cases, document and whitelist those contexts explicitly rather than allowing open-ended malware code requests.
- Add output-side review for generated code that touches privilege escalation, credential files, or low-level system hooking before it is used or shared.

## Known benign look-alikes

- Security researchers writing controlled PoC code in documented CTF or lab environments
- Antivirus/EDR vendors requesting code examples for detection signature development
- Academic courses on malware analysis with explicit educational framing
