Written by

in

Methodology walkthrough. Client details are withheld and no recovery outcome is implied.

The situation

A user signed a malicious approval that let an attacker move specific tokens out of the wallet over time.

Our approach

  • Identified the malicious approval and the spender address.
  • Traced the drained tokens to their destination wallets.
  • Advised on revoking outstanding approvals to stop further loss.

What we can honestly describe

Stopping ongoing loss by revoking approvals is often the first priority; tracing the already-moved assets follows. We provide rigorous investigation and honest counsel, not guarantees. Request an assessment.
