Secure your business with CyberHoot Today!!!

Hackers have found a new way to trick unsuspecting users into clicking on phishing links. Attackers use a marketing feature on a business networking website that lets them create a link that bounces your browser to other websites, such as phishing pages that mimic top online brands. This malicious strategy is called “Slinking”. 

LinkedIn Slinking Attacks

LinkedIn has a redirect feature available to businesses that choose to market through The LinkedIn redirect links allow customers to track the performance of ad campaigns while promoting off-site Secondary website links. These links or “Slinks” all have a standard format: “” followed by a short alphanumeric variable. The first Slink created,, redirects to the homepage for LinkedIn Marketing Solutions.

It seems like a good idea for companies that are trying to grow their business, but hackers have infiltrated this tool. The problem is there is little to stop criminals from leveraging newly registered or hacked LinkedIn business accounts to create their own ad campaigns using Slinks., a free service that provides detailed reports on any scanned URLs, also gives a historical look at suspicious links submitted by other users. This search via Urlscan reveals dozens of recent phishing attacks that have leveraged the Slink’s feature.

Below is an example from a January 2022 attack, where hackers used links to redirect users to a site that spoofs Adobe and prompts users to log in to their Microsoft email account (giving your credentials to the hackers) to view a shared document: 

Adobe isn’t the only Slink Phishing Attack, URLscan has found more attacks that spoof Amazon, PayPal, and even the Internal Revenue Service (IRS). It’s expected that attackers won’t stop at those domains, especially if the attacks keep on working by fooling unsuspecting users. 

One of the security challenges with these attacks is that phishing emails leveraging LinkedIn’s Slinks are unlikely to be blocked by anti-spam and anti-malware filters,. This is because LinkedIn is widely considered a trusted domain, and the redirect obscures the link’s ultimate destination.
