Those who know me are aware of my low opinion about tracking links in general and URL shorteners specifically.

By default, I despise them because they are used to violate the privacy of the email recipient by collecting personal (using the GDPR definition here) information from any recipient who clicks on the link. Companies using them argue there is a legitimate interest to collect that data, namely to verify the effectiveness of their marketing campaign. Well, GDPR will say that marketing is never a legitimate reason to collect personal data.

Now, knowing whether your phishing email was effective is something the more sophisticated phisher would be interested on. After all, the best commercial rent-a-phish tools do produce reports telling how many emails were opened and, of those, how many had their links clicked.

But wait! There is more! Tracking links also make it that easier for phishers to hide their intention: they do not need to go to a “phishers-only” service: any commercial tracking link/ URL shortene service will gladly take their money. Case in point is the next phishing email:

From: "Bank of America" <accounting@mysecureprotection.com>
To: Clueless Phish <cluelessphish@example.com>
Subject: You Have A New Message
Date: 14 Nov 2024 02:40:56 +0100

Right you are, and we can see other telltale signs of a phish at large:

  • Interesting grammar
  • If you do not have a Bank of America account, receiving such email is a dead giveaway.
  • I was going to make fun of the subject of this email, “You Have A New Message”, but banks and credit card companies are notorious for having suspicious Subjects. While they claim that is done to “make it harder for malicious attackers to immitate them,” the reality is as if they are trying to copy thge phishers. While I appreciate them having something to strive for, that is not what they should be aiming for.
  • Same goes for the return email address. I am sorry but it sure looks suspicious: why would Bank of America not use bankofamerica.com for its return address? I would love to say “Aha! That is another dead giveaway!” but I could name 3 other banks who have cutesy addresses for who knowa why. Still, it is suspicious in my book, so I would not click on the link.

But this phish has a twist. Behind the “[Login Here to view the Message Center]” is a short link. Specifically, a t.co links which indicate it was created using Twitter/X’s link service. I expand the link, and it goes to https://cameoutair.com/bl2/jsde5/SOME-PAGE.htl (I do not want you to accidentally click on their site). Do you remember when I talked about suspicious sites ealier on? I do not think (or hope) that cameoutair.com is a domain owned by Bank of America. But, the only way to figure out that the link was even more suspicious was to expand the shortened link.

Bottom line is phishers are getting better as they are making use of sleazy commercial products like link shorteners.

What should I do then?

  1. Just say no to link shorteners and tracking links!
  2. If you receive such email and do have a Bank of America (or whatever bank you use) account, do not click on the link! Login into the official bank’s website and see if there is a message. If not, contact their support. Yes, I know that can be frustrating but it is the only way to be sure.
