The Google Critical Security Alert scam tricks potential victims into exposing their account credentials or lured into downloading malicious programs. Potential victims receive an email in their Gmail inbox which warns about unauthorized sign-in and encourages them to take precautionary measures to prevent unauthorized activity. But, if the potential victims follow the instructions in the fake notification by clicking the link in it, they will be taken to a phishing website that steals account credentials or a malicious website that tricks them into downloading malware.
