Clicked a scam link? Do this first
Start with what actually happened: did you only open the page, enter information or run a file? That determines the next step.
Stop the interaction and note what you clicked or disclosed. Contact IT immediately if a work account is involved.
If you only opened the page
Close the suspicious page. Do not sign in, enter codes or install anything. Keep the message and the time for reporting. For work-related phishing, follow your organisation's reporting process. Also check whether anything downloaded or the browser displayed a security warning.
If you disclosed a password or approved a sign-in
- Contact IT immediately for a work or school account. For a personal account, open the service's genuine app or website yourself and secure the account. [1]
- Change the affected password from a safe device and replace reused passwords on other services. Sessions and recovery methods may also need review. [1]
- Also report whether you entered a device code or approved MFA. Traficom describes attacks where a code entered in a genuine Microsoft service can give an attacker access; a familiar sign-in page is therefore not enough reassurance. [2]
If you ran a file and suspect malware
On a work computer, contact IT immediately. A device with a suspected active infection should be isolated from the network to limit damage. Do not routinely shut down or clean the computer before IT assesses evidence and recovery needs. CISA describes isolation and the risk of losing volatile evidence when shutting down. [3]
If you disclosed bank or card details
Contact the bank or card issuer through a known official channel and explain what happened. Do not wait for another message from the sender. Report fraud to the police. [1]
