LinkedIn Smart Links abused in evasive email phishing attacks

Phishing actors are abusing LinkedIn’s Smart Link feature to bypass email security products and successfully redirect targeted users to phishing pages that steal payment information.

Smart Link is a feature reserved for LinkedIn Sales Navigator and Enterprise users, allowing them to send a pack of up to 15 documents using a single trackable link.

Phishing actors aren’t just using Smart Link for bypassing email security protections but can also gain insight into the effectiveness of their campaigns, allowing them to optimize their lures.

The new trend of Smart Link abuse for phishing was spotted by threat analysts at Cofense, who have observed campaigns targeting Slovakian users with bogus postal service lures.

The embedded “Confirm” button contains a LinkedIn Smart Link URL, with added alphanumeric variables at its end to redirect the victim to a phishing page.

While this still-ongoing campaign targets Slovakians, the abuse of LinkedIn Smart Link by phishing actors with a broader scope may be just a matter of time.
