Researchers at Avanan have observed a phishing campaign that’s impersonating the WeTransfer file-sharing app in an attempt to steal users’ credentials. The email’s subject line states, “You received some important files via WeTransfer!” The body of the email informs recipients that they’ve received three files through the service, with a link to “Get your files.”
The text of the email was worded awkwardly, however, which could tip some users off:
“Dear Sir/Madam,
Attached is our order catalogue and PO-209-2021 And Terms & Condition, please check if you can provide us with those, and quote.
Look forward to have a cooperation with you ,thanks.”
The email also states “Will be deleted by April 5, 2021” to instill a sense of urgency and motivate users to click the link. The link leads to a convincingly spoofed version of WeTransfer’s website, with a popup presenting a button for the user to download their new files. The names of the files are “List of Items.pdf,” “Drawings and Specifications.zip,” and “Company Profile.mp4.”
If the user clicks the button, they’ll be taken to a login page to verify their WeTransfer credentials. When they try to log in, their credentials will be sent to the attacker. The victim will be told that a technical error occurred, and the site will request that they re-enter their password.
“Hackers will do anything to get in your inbox,” Avanan concludes. “Posing as a trusted file-sharing source, with an email you may often get, tends to be a good way to do that.”
While this phishing attack isn’t highly sophisticated, some people will still probably fall for it. Avanan notes that the phishing site’s URL clearly didn’t resemble WeTransfer’s legitimate URL, so observant users could have recognized the scam. New-school security awareness training can teach your employees how to spot the signs of phishing attacks.
