Alphabay owner used email address for both Alphabay and LinkedIn profile.

BarbaraHudson writes: The Register is reporting that Alexandre Cazes, the 25-year-old Canadian running the dark web site Alphabay, was using a hotmail address easily connected to him via his Linkdin profile to administer the site

... he used his real email address, albeit a Hotmail address – [e-mail] – as the administrator password for the marketplace software. As a result, every new user received a welcome email from that address when they signed up to the site, and everyone using its password recovery tool also received an email from that address.

However, rather than carefully set up and then abandon that email address, it turns out that Alexandre Cazes — Pimp Alex — had been using that address for years.

Cazes had also used his Pimp Alex Hotmail address as well as an email address from his own business – EBX Technologies — to set up online bank accounts and crypto-currency accounts. How did law enforcement know that Cazes was behind EBX Technologies? It was on his LinkedIn profile.

His laptop wasn't encrypted, so expect more arrest as Alphabay users are tracked down.
