On August 3, 2015, ISIS-affiliated Twitter account@AbuNaseeha03 tweeted a link to the Electronic Frontier Foundation (EFF) Secure Messaging Scorecard,[1] which rates the security of various messaging apps and services, as a reference guide for jihadis who wish to communicate anonymously and undetected by using encryption. Text accompanying the tweet read: "Check this website from time to time regarding the safety of Messaging Apps."
EFF is a U.S.-based international nonprofit organization founded in 1990 that works to protect digital civil liberties. It advocates privacy, free expression, and innovation through impact litigation, policy analysis, grassroots activism, and technology development.[2] The Secure Messaging Scorecard includes many apps popular with jihadis, including: ChatSecure + Orbot; Kik; Skype; Snapchat; SureSpot; Telegram; Threema; Viber; WhatsApp; and Wickr.
