The Black Friday and Cyber Monday festivities have inundated the market with low-priced tablets aimed at budget-conscious shoppers. While these inexpensive tablets may seem like a great deal, a study from mobile security firm Bluebox says several models contain security breaches exploitable by hackers.

Bluebox tested 13 Android tablets from various retailers priced under $100 with their free software, Trustable. Tablets were assessed for backdoors, and malware vulnerabilities as well as security misconfigurations such as having administrator or root privileges enabled by default. The test devices were then ranked based on their threat level.
