The Deceptive Face of “Unsubscribe”
It’s no longer a surprise that the cyber threat landscape is continuously evolving, and cybercriminals are relentlessly innovating ways to infiltrate and exploit unsuspecting users. The most recent deceptive method brought to our attention is the “Non-Subscribe” attack by our partner mSOC. This ploy deceives users by providing an “Unsubscribe” button in spam emails, drawing them into a trap under the facade of halting unwanted communications.
Understanding the “Non-Subscribe” Attack
The Deceptive Email: Users receive a spam email, often with a subject line that’s attention-grabbing or concerning. While the topic of the email might seem irrelevant, the purpose isn’t the content itself, but the “Unsubscribe” button embedded within.
The Trap: Clicking on “Unsubscribe” redirects users to a web page. This page may be eerily identical or closely resemble a legitimate-looking platform, as seen in the shared screenshot. Unsuspecting users, believing they are on a genuine page, enter their email address to unsubscribe.

The Motive: Contrary to what one might think, these users never subscribed to the emails in the first place. By entering their email address, they inadvertently validate their email address for cybercriminals. Moreover, the “Unsubscribe” button isn’t just for email harvesting – it has been leveraged for other mischievous activities as well.
In the case of this attack, an examination from mSOC of the Proofpoint log entry marked “SPAM” affirms the malicious nature of such emails. The payload URL embedded within these emails further underscores the need for caution.
