Description

Linkedin is releasing a software product named "Linkedin Intro" that promises to integrate iOS mail clients with the Linkedin service, promising to provide information on how people are connected and other information to users. This is performed by piping/proxying mail accessed through Linkedin's servers to process the incoming mail regardless on who hosts the mail server. Digibase classifies this software as trojan spyware as it provides a promise of positivity but bait and switches it with scanning information not privy to them.

Mitigation/Solution

All users affected are advised not to utilize the "Linkedin Intro" software and to remove it if it exists already on devices. It is further advised to treat this software as malware.
