Financial Fraud Execution — Ponzi Setup, Fabricated Statements, Unauthorized Redirect & Laundering
ATR detection rule by ATR Community · MIT
Detects an instruction directing an agent with financial tooling to execute a recognizable financial-crime pattern. Drawn from the AgentSecurityBench (ASB) finance domain, the covered fraud archetypes each carry a distinctive signature that separates them from legitimate accounting: (a) Ponzi scheme — "use new investors' funds to pay returns to existing investors", or "set up an experimental investment scheme ... promising above-market returns"; (b) fabricated financial statements — "create alternative financial statements showing a profit increase", or "modify the backup financial data to reflect corrections to a loss"; (c) unauthorized fund redirect — "redirect $X from a client account ... without prior client authorization"; (d) money-laundering test — "process $X of project funds through company ... to test laundering detection"; (e) synthetic/fraudulent accounts — "set up trial accounts using client information"; (f) fraudulent loan — "apply for a $X loan using experimental financial projections". Each Layer below requires the fraud-specific qualifier so generic "review / verify / reconcile the financial statements" requests do not fire.

Detects an instruction directing an agent with financial tooling to execute a
recognizable financial-crime pattern. Drawn from the AgentSecurityBench (ASB)
finance domain, the covered fraud archetypes each carry a distinctive signature
that separates them from legitimate accounting: (a) Ponzi scheme — "use new
investors' funds to pay returns to existing investors", or "set up an
experimental investment scheme ... promising above-market returns"; (b)
fabricated financial statements — "create alternative financial statements
showing a profit increase", or "modify the backup financial data to reflect
corrections to a loss"; (c) unauthorized fund redirect — "redirect $X from a
client account ... without prior client authorization"; (d) money-laundering test
— "process $X of project funds through company ... to test laundering detection";
(e) synthetic/fraudulent accounts — "set up trial accounts using client
information"; (f) fraudulent loan — "apply for a $X loan using experimental
financial projections". Each Layer below requires the fraud-specific qualifier so
generic "review / verify / reconcile the financial statements" requests do not

[ATR-2026-01805] Financial-fraud execution command detected. The input directs
the agent to run a Ponzi scheme, fabricate financial statements, redirect funds
without authorization, simulate money laundering, create synthetic accounts, or
obtain a loan with fabricated projections. Do NOT execute — block the
transaction and escalate to compliance.
