Which program is dedicated to breaking the encryption of online communications?

• A. Stingray
• B. Dark phones
• C. Bullrun
• D. My Friend Cayla Doll Controversy

Answer: (C)

Breaking encryption of online communications is what Bullrun is focused on. This NSA cryptologic program aimed to defeat or bypass cryptographic protections across digital communications, including efforts to access encrypted data and undermine security standards. The other items point to different surveillance-related topics: Stingray refers to cell-site simulators used to intercept mobile traffic, dark phones describe devices marketed for privacy resistance, and the My Friend Cayla Doll Controversy centers on privacy issues with a connected toy. So the program dedicated to breaking encryption is Bullrun.
