LinkedIn Phishing Scam Methods:

1. Connections with Fake LinkedIn Profiles

On LinkedIn, users are encouraged to build and engage with other users on a professional level and you assume everyone has good intentions. That’s not always the case.  Fake profiles are common on social media platforms; this form of scam works well on LinkedIn because of the professional nature of the platform.

What’s bad about fake LinkedIn members? Phishing hackers have been known to build a rapport with their targets through likes/comments/messages/posts then will request sensitive information from you. With the professional nature of LinkedIn, it’s easier to feel trusting of all profiles.

2. Pretending to be LinkedIn and Requesting Information

If you use LinkedIn, you’ll know that they send a lot of emails. Hackers have used this to their advantage by sending emails pretending to be LinkedIn.

This form of a scam will typically be in the form of a fraudulent email sent from an account masquerading as the administrative team. This email may contain a hyperlink that is requesting more personal information. Once visited, you could be taken to a page that looks like the LinkedIn website. The site will ask you for your email address and password, once entered this will give your credentials to the scammer.

3. LinkedIn Inmail Scam

This SCAM is sent in the form of a message using the built-in messaging system and usually contains a link to a fake or malicious website which the scammer could use to harvest information or to try and get you to download malicious software onto your computer.

How to protect yourself against Phishing Attacks:

  •  Check the email address of any emails appearing to be sent from Linkedin. Avoid any that have a non-LinkedIn domain.
  • Hover over any hyperlinks sent within emails or messages received to check it takes you to an official LinkedIn webpage. If you received the email below, would you click on these links?

  • Verify the validity of the email by logging into your LinkedIn account; the notice should also be in there.
  • Avoid any emails asking you to install the software.
  • Avoid any emails or messages containing poor spelling or grammar.
  • If you do click a link on an email from LinkedIn, check certificate of a site
  • Common sense -unsure? www.linkedin.com and LinkedIn will notify you if there is an issue with your profile security. and e.g. if you’ve not requested a password reset, then ignore any emails which ask you to reset your password!
