LinkedIn Phishing Scam: Motives Unclear, but Still a Threat

We seem to write about a new phishing or spear phishing scam every day.

This latest LinkedIn scam has all of the classic signs of phishing. It comes from a suspicious sender, has bad grammar, and even uses an urgent call to action to scare victims into clicking the link. A link that appears to go to a blank page hosted by Linkedin. The motives for this attack remain unclear, and it could signal a larger threat in the future.

This scam has all the signs of a standard phishing attack…

Suspicious Sender

The latest LinkedIn phishing scam entices victims with an urgent subject line stating, “Important User Alert”. Although this subject line seems legitimate, anyone with phishing training who is paying attention would notice that it comes from a suspicious email address, “linkedin.customerservice.us1@fsr.net”. Even if, “linkedin.customerservice.us1,” is convincing enough for users to open the email, the “fsr.net” should be a red flag that something is not right.

Generalized Introductions

The email begins with, “Dear valid LinkedIn user,” which doesn’t seem that strange. However, LinkedIn knows it’s users’ names and has the tools to address their users by name in any email they send. These types of generalized introductions are often utilized in “spray and pray” phishing attacks because hackers can send one email to thousands in the hopes that someone will fall for the attack.

Urgent Action and Terrible Grammar

The content of the email threatens that users could lose privileges and access to their LinkedIn accounts unless they click on an enclosed link. One portion of the email reads:

The email continues in the same fashion with rampant grammatical errors and strange capitalization, another indication that the email isn’t really from LinkedIn. LinkedIn is a well-established brand owned by Microsoft; they hire better copywriters than that.

…but the link doesn’t lead anywhere.

The strangest thing about this particular phishing scam is that the link leads to a blank LinkedIn page. This could be for a number of reasons, including:

  • The fraudulent login page could be unfinished
  • The hackers could have sent out an incorrect
  • A page might originally have been malicious but was shut down by LinkedIn.
  • The hackers are simply testing out their technique to see if they can set themselves up for a larger malicious campaign.

It’s this last item that should be most concerning to system admins and security professionals. This phishing attack, despite its apparent clumsiness, easily sailed past the vast majority of email security filters. Had this been a real attack, it could have leveraged a myriad of social and technical vulnerabilities to do great damage. Maybe next time they will.

Although this attack is seemingly harmless, it is important to understand what kind of data breaches could have taken place.
