This Credential Phish Masks the Scam Page URL to Thwart Vigilant Users
By Milo Salvia, Cofense Phishing Defense CenterTM
The Cofense Phishing Defense Center (PDC) has observed a phishing campaign that aims to harvest credentials from Stripe, the online payment facilitator handling billions of dollars annually, making it an attractive target for threat actors seeking to use compromised accounts to gain access to payment card information and defraud consumers. The phish prevents email recipients from seeing the destination of an embedded link when they try to hover over the URL. Instead, what they see is a bogus account message. Here’s how the campaign works.
The email pretends to be a notification from “Stripe Support,” informing the account administrator that “Details associated with account are invalid.” The administrator needs to take immediate action, otherwise the account will be placed on hold. This is cause for panic among businesses that rely solely on online transactions and payments. Fear and urgency are the most common emotions threat actors play on, spurring otherwise rational people to make irrational decisions.
Figure 1: Email Body
The email body contains a button with an embedded hyperlink, as seen above: “Review your details.” When clicked, the recipient is redirected to a phishing page. Usually one can check the destination of the hyperlink by hovering over it with the mouse curser. The true destination of this hyperlink is obscured by adding a simple title to HTML’s <a> tag, which shows the recipient the title “Review your details” when the recipient hovers over the button instead of the URL. Potentially this is a tactic to mask the true destination from a vigilant recipient.

The phishing page is an imitation of the Stripe customer login page. In fact, it consists of three separate pages. The first one aims to harvest the admin’s email address and password, while the second page asks for the bank account number and phone number associated with the account. Lastly, the recipient is redirected back to the account login page which displays an error massager, “Wrong Password, Enter Again.” This leads the recipient to believe an incorrect password has been entered and redirects back to the legitimate site, so the recipient doesn’t suspect foul play.
