Phishing Email Spoofs Microsoft Alert

Cyberattack uses fake Microsoft alert to steal login credentials

Threat actors are sending phishing emails disguised as fake Microsoft Office account security alerts. The notification prompts the user to click on a link to review suspicious activity. If the target follows the instructions, their Microsoft Office account is compromised.

The Microsoft phishing email is crafted to look like a security notification. The subject line informs the reader that there has been a new sign in to their account. To make this attack more believable, the threat actor has spoofed the email domain of the target’s workplace and impersonated Microsoft.

The target is informed that there has been a new login to their Microsoft account. The messaging in the body of the phishing email looks like a typical new login alert – it lists an IP address of the new login and states that a Windows computer was used. The sender’s email address spoofs the victim’s corporate email, says a report by researchers at Abnormal Security. The messaging in the email attempts to scare the user and get them to act quickly to review this suspicious activity. They are instructed to click on a link to review their account.

If the victim clicks on the link in the alert, they are taken to a credential phishing page which uses Microsoft branding and design – which it is not. The victim’s email address is already filled in – making it even easier and faster for the victim to make a mistake. The credential phishing page instructs the user to enter in the Microsoft password. If they do so, their credentials are sent to the hackers and their work account is compromised.

Employees who use Microsoft Office for their work email are frequent targets of cyberattacks. The hackers are looking to gain access to personal data and valuable corporate emails. Once an email account is compromised, the threat actors can then scan emails looking for sensitive work documents, to gain access to financial accounts, or access other private information.
