Thanks - you're right. I was mixing PRISM with MUSCULAR. Wasn't PRISM still limited to data around high-interest individuals? (i.e. not a blank check to all data) Was BULLRUN what ATT room 641a was involved with?

Uncertain; that was my initial understanding as well, but the Wikipedia article on PRISM indicates that certain search terms are fair game as well. Also uncertain about the relationship between BULLRUN and AT&T room 641A. My understanding is that BULLRUN is different, focusing on influencing encryption standards so that the government could break them, but I'm not sure.

  BULLRUN appears to be an umbrella term for all efforts to crack encryption directly, not just efforts to influence standards. For instance their VPN cracking systems probably fall under BULLRUN. I think it was never entirely clear what PRISM is: the only slides that covered it were vague and were directly contradicted by the testimony of the relevant CEOs.

    It's pretty clear from a couple of the slides: https://nsa.gov1.info/dni/prism-slides/PRISM-tasking%20process.jpg https://nsa.gov1.info/dni/prism-slides/PRISM-tasking%20proce... https://nsa.gov1.info/dni/prism-slides/prism-conclusion.jpg https://nsa.gov1.info/dni/prism-slides/prism-conclusion.jpg Note the presence of FAA Adjudicators and FISA Oversight & Processing in the collection pipeline in the first slide, and the direct reference to "FAA 702 collection = PRISM program providers" in the last. The director of national intelligence also confirmed it in response to the leaks: https://www.dni.gov/index.php/newsroom/press-releases/191-press-releases-2013/869-dni-statement-on-activities-authorized-under-section-702-of-fisa https://www.dni.gov/index.php/newsroom/press-releases/191-pr...
