## Polkadot Foundation Warns
Polkadot Community Foundation warns Fearless Wallet browser extensions 3.0.1-3.0.5 may have exposed private keys since February 2025.
## Exposed Keys Risk
The extension code sent private keys to attacker-controlled servers from February 2025 through October 10, 2026, risking 17,286 DOT in unauthorized transactions.
## User Action Required
Users must create new key pairs in another wallet and transfer assets; changing passwords or reinstalling extensions won't secure exposed keys.
## Key takeaway

Polkadot Community Foundation says Fearless Wallet extensions 3.0.1-3.0.5 exposed private keys since February 2025, risking 17,286 DOT in unauthorized transactions.
