Out of interest I clicked on the link in one of their "phishing" emails and I was redirected to a link where they essentially told me "never click on links in emails, you never know where they lead to". One week later I get an email "please click on this link to complete the second part of your course". Obviously I never completed their course, they told me never to click on links.
What's even worse is that they don't even use their own domain for the courses, but some random looking domain.
I also did this at work, and yeah it was a fake phising mail sent by a security company, and I had to do a quick 20 min online course on email security best practices. Yay. Me and like 3 other dudes, who clearly all also understood it was phising and were just curious about the scam.
Just shows how bad they are at faking it.
"Hi, I'm XYZ from XYZ background checks, I'm conducting your pre-employment check, and I just want to confirm that your full name is V, your DOB is W, your place of birth is X, your address is Y and your full SSN is Z...
... and that this is the correct email address for you. Please confirm."
Holy hell. Thankfully I reached out to the employer about this (and the background check company's attempt to reach out to my partner on Facebook for ... something? This wasn't a security check, just a regular employment background) and they were as horrified as me, apologized, and fired their background check provider.
