Key Details of the Scam
The "Sign-in Attempt Was Blocked" phishing email often uses subject lines like "Critical security alert." The email falsely claims that a blocked sign-in attempt was made using the recipient’s password. It then urges the recipient to "Check Activity," directing them to a phishing site disguised as an email login page (using Zoho Office Suite branding in some cases). Any credentials entered on this page are stolen by cybercriminals, enabling them to hijack email accounts.
Consequences of Falling for the Scam
- Identity Theft: Stolen credentials can lead to identity theft and fraudulent activities.
- Financial Loss: Compromised finance-related accounts can result in unauthorized transactions.
- Spread of Malware: Hijacked email accounts can be used to distribute malware or other phishing scams.
- Reputation Damage: Scammers may impersonate the victim to deceive their contacts.
