"Bluebox Labs purchased over a dozen of these Black Friday 'bargain' Android tablets from big name retailers like Best Buy, Walmart, Target, Kmart, Kohl's and Staples, and reviewed each of them for security," the company wrote on its blog. "What we found was shocking: most of the devices ship with vulnerabilities and security misconfigurations; a few even include security backdoors.

Unfortunately, unsuspecting consumers who purchase and use these devices will be putting their mobile data and passwords at risk."
