I’ve been hacked. What should I do?

Even if you’ve taken steps to protect your devices and accounts, you can still be hacked. But it’s not too late to recover and protect yourself or your business.

First, you should make a record of the key details of the incident. This includes what happened, when it happened, if someone contacted you, and how you responded.

These are things you can do to stop further access by the hacker:

  • Disconnect from the internet.
  • Scan for viruses to identify and remove any malware.
  • Change all your passwords and passphrases.
  • Notify your social network to be on the alert for any strange links or email attachments.

If someone has stolen sensitive data, you should contact these agencies to report it, get help, and reduce further harm.
