<recipient's address> Authenticator Sessions Timeout (2024-03-08)


Threat actors collecting ZIMBRA login credentials


Threat actors are attempting to collect ZIMBRA login credentials.

The message states that the recipient’s Login Authenticator sessions will expire and prompts them to re-authenticate their login security by scanning the QR code. To increase credibility, the phishing email mentions the recipient’s email address several times.

Upon entering their credentials on the phishing landing page, which closely resembles the legitimate ZIMBRA login page, the information is directly sent to the threat actors.
