Attack Type: Credential Phishing

Credential phishing attacks are designed to steal your login information by tricking you into entering it on fake login pages. These emails impersonate trusted services like Microsoft 365, Google Workspace, or banking sites, using urgent phrases like “verify your account,” “prevent suspension,” or “view shared document” to push you into clicking.
Once you click the link, it leads to a fake login page that looks convincing. If you enter your credentials, the attacker captures them immediately. Common examples include phishing emails pretending to be DocuSign requests, Dropbox links, or HR file shares—things that feel routine but create a false sense of urgency.
Attackers often use real platforms like Microsoft Forms, Google Forms, or compromised websites to host these fake login pages, making the links appear legitimate and harder for security tools to catch. The damage doesn’t stop at just stealing your login. Once attackers gain access, they can move through your organization, steal sensitive data, send internal phishing emails, or even launch a ransomware attack.
