If you suspect that your crypto wallet has been compromised, it is important to take action quickly to prevent any further damage or loss. Here are some steps you should take:

1. Immediately move your assets to a secure, new wallet that you know has not been compromised. This will help to protect your assets and prevent the attacker from accessing them.
2. Change your passwords and security credentials for your wallet and any related accounts (such as email or exchange accounts) as soon as possible. Use strong, unique passwords and enable two-factor authentication wherever possible.
3. Check your transaction history to see if any unauthorised transactions have occurred. If you notice any suspicious activity, contact your wallet provider or exchange immediately to report the issue.
4. Scan your computer or mobile device for any malware or viruses that may have caused the compromise. Use reputable antivirus software and keep it up-to-date to prevent future attacks.
5. Report the incident to the relevant authorities, such as the police or your country's financial regulator, if you believe you have been a victim of a crime. Keep any evidence or documentation related to the incident for their investigation.

Remember, the best way to prevent wallet compromise is to practise good security habits, such as keeping your software and devices up-to-date, using strong passwords, and not sharing your private keys or recovery phrases with anyone. Stay vigilant and take action quickly if you suspect your wallet has been compromised.
