# 'Silent Swap' clipper hides in a fake Google Notes browser extension to swap wallet addresses

- Severity: Medium · Status: Still active (past)

- Who/what: Chromium browser users infected via unsigned installers (fake 'Google Notes' extension)

McAfee researchers found unsigned .NET and Go installers, linked to the CountLoader malware loader, that force-install a fake 'Google Notes' extension into Chromium browsers. The extension reads the clipboard and replaces copied Bitcoin, Ethereum, Bitcoin Cash, XRP, Dash and Solana addresses with attacker addresses; it finds its control server through a smart contract. Anyone who finds an unknown 'Google Notes' extension should remove it and treat anything copied while it was installed as exposed. No loss total was published.

## Am I affected?
Check your browser's extensions page. If you see a 'Google Notes' extension you did not install from the official store, or it has clipboard and all-sites access, you are affected, especially if you recently ran cracked or unsigned software.

## What to do now
Remove the extension and scan the PC; the installer may have changed browser settings, so a clean reinstall is safest. Compare recent outgoing transfers with the addresses you meant to use. Move funds if you copied any seed phrase or key while infected.

## How to avoid this
Do not run unsigned or cracked installers. Install extensions only from official stores and review their permissions. Confirm the full receiving address on a second screen or hardware wallet before sending.

Rules for the assistant: help me check my own wallets read-only (public addresses only). Never ask for or handle a seed phrase or private key. Point me to official revoke tools and the wallet's own support.
