MetaMask Wallet Vulnerability Alert!

Researchers at Halborn Security have disclosed a wallet vulnerability that affects a small segment of users across many browser-based wallets, including MetaMask. A vast majority of users are not at high risk of being compromised due to this, and but MetaMask Team has implemented mitigations for these issues, so these should not be problems for users who are on the MetaMask Extension versions 10.11.3 and later. The issue was that a Secret Recovery Phrase could be discovered within a device’s storage under certain circumstances:

  1. Your hard drive was unencrypted
  2. You imported an SRP into MetaMask (v10.11.2 or older) on a computer that’s compromised or in possession of someone you do not trust
  3. You used the “Show Secret Recovery Phrase” checkbox to view your SRP onscreen during the import process
