Incident Overview
On December 26, 2025, Trust Wallet Browser Extension version 2.68 was compromised, resulting in approximately $6-7 million drained from users' wallets after a malicious update pushed to the Chrome Web Store.
The breach was first flagged on December 25 by on-chain detective ZachXBT who noticed multiple Trust Wallet users reporting funds being drained within hours of the Chrome extension pushing a new update to version 2.68. The compromised extension gained access to users' private keys, allowing malicious actors to authorize unauthorized transfers of cryptocurrency to attacker-controlled addresses. The exploit exclusively affected Browser Extension version 2.68, with mobile-only users and all other browser extension versions remaining unimpacted.
Trust Wallet quickly identified the security incident and released version 2.69 as a secure replacement, urging users to disable version 2.68 immediately and upgrade through the official Chrome Web Store. The rapid movement of stolen funds to multiple centralized exchanges suggests a coordinated laundering operation, though the involvement of regulated exchanges may facilitate potential fund recovery efforts.

What Auditors Should Check
If you're auditing a protocol with similar architecture to Trust Wallet, these are the critical security checks that could have prevented this incident (December 2025).
- Verify all logic paths related to Private Key Compromised (Supply Chain Attack) / Access Control are guarded by proper access controls and input validation - see the Access Control Attacks attack class for patterns
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
