Not just LinkedIn profiles: there was a case out here near DC a while ago where a well known company leased out their function space for training meetings. Using a compromised company account, a set of scammers set up some fake recruitment profiles, leased out the meeting space for “software training,” and did some “mass hiring” where 30 individuals had their credentials scanned and duplicated. The effect was someone from the recruiting company was contacting you, you had a face-to-face where you got offered an in-person, you showed up to their offices, and got a “job offer pending a background check,” with a date of hire in official-looking emails. You sent in your SSN, copies of your passport and driver’s licence, and after a few weeks, they tell you to show up for orientation. Only, the day these people showed up, the company was confused and had never heard of you. The people you supposedly spoke to had never heard of you. And your identity was stolen, and huge loans and charges started showing up in your credit report.

Yikes.
