The brainchild of researchers at the University of Illinois at Chicago, Cloudsweeper’s account theft audit tool scans your inbox and presents a breakdown of how many accounts connected to that address an attacker could seize if he gained access to your Gmail. Cloudsweeper then tries to put an aggregate price tag on your inbox, a figure that’s computed by totaling the resale value of other account credentials that crooks can steal if they hijack your email.
