1. Did you click on any links or download any attachments in the email?

Disconnect your Internet connection and inform your System Administrator immediately. You might have just installed malware into your computer, which will transmit information to the attacker. Your System Administrator might update your anti-virus program and run a full scan.

Depending on the results of the scan, your System Administrators might reinstall the operating system to remove all hidden threats and start from a clean slate.

2. Did you provide your username/password/account details?

Change your passwords for these affected accounts immediately. You might want to consider changing your username as well. Inform your System Administrator about this leak of information so that they are able to advise the accounts affected by this attack. 

3. Did you provide your financial information e.g. bank account number, credit card number?

Report this attack to the relevant authorities and inform the affected financial institutions. Change your account numbers and credit card numbers. Close all accounts related to those affected by the phishing attack. Look out for signs of identity theft for the next few months.

4. Did you provide corporate information?

Inform your superiors and your System Administrators about this as soon as possible so that they are able to act on this.

5. Did you send in personal information about yourself e.g. Singpass details, NRIC?

Report this attack to the relevant authorities. Look out for signs of identity theft for the next few months.

Consult your System Administrator for any advice. The worst case scenario is to reformat your computer, followed by a reinstallation of the operating system. As such, it’s always a good practice to update your backup as a final protection against such attacks.
