The short answer
Some wallet scams persuade users to approve a contract or sign a message that they do not understand. The danger may not be visible as a conventional account login. Preserve the site URL, the request shown, the transaction hash and the wallet or provider involved.
What to check and preserve
The European authorities advise victims to disconnect and revoke suspicious access. Use trusted wallet documentation and official security tools to understand available controls. A disconnection in an application interface and revocation of an on-chain approval may be different actions; do not assume one automatically performs the other.
Limits and important distinctions
Revocation cannot undo a transfer that has already occurred, and poorly chosen tools can themselves be malicious. Do not sign unexplained transactions to 'repair' a wallet. If uncertain, obtain competent technical help and do not grant a helper your secret keys or unrestricted remote access.
Checklist
- Keep the approval or signature details.
- Use independently verified wallet guidance.
- Distinguish application disconnection from contract permissions.
- Never sign an unexplained recovery transaction.
