La mystérieuse salle 641A… qui vous surveille

https://www.youtube.com/watch?v=RXF5sJch378

Au 611 Folsom Street, à San Francisco, il y a un grand immeuble. Celui d’AT&T, le plus grand Télécom américain. Il n’y a rien de bien particulier là-bas. Juste des centaines d’employés qui bossent, tous les jours, pour assurer les communications du pays.

Mais au 6ème étage, il y a un endroit étonnant. La pièce 641A. Une salle où personne n’a accès

When the New York Times reported in late 2005 that the NSA was engaging in #spying inside the #US, Mark realized that he had witnessed how it was happening. He also realized that the President was not telling Americans the truth about the program. And, though newly retired, he knew that he had to do something.

In Memoriam: Mark Klein, AT&T Whistleblower Who Revealed NSA Mass Spying

[W]hat Mark told us changed everything. Through his work, Mark had learned that the National Security Agency (NSA) had installed a secret, secure room at AT&T’s central office in San Francisco, called Room 641A. Mark was assigned to connect circuits carrying Internet data to optical “splitters” that sat just outside of the secret NSA room but were hardwired into it. Those splitters—as well as similar ones in cities around the U.S.—made a copy of all data going through those circuits and delivered it into the secret room.

Klein provided one of the pre-Snowden disclosures of massive communications surveillance in the United States. I'd included him in an earlier toot from May 2021: https://toot.cat/@dredmorbius/106251396105180975

His story also demonstrates that "surveillance state" and "surveillance capitalism" aren't separate things, but part of the same larger surveillance octopus.

US Domestic Surveillance Disclosures pre-dating Edward Snowden's Revelations

Asking for sources of any current activities met with some resistance at HN. Challenged for any awareness of pre-Snowden programmes, I listed a few I was aware of, off the top of my head:

Regards pre-Snowden, the situation was far more than an "open secret", there were multiple documented projects and methods employed. Among them:

• 2013: Hemisphere, an AT&T call records database dating to the 1980s accessible by the US DEA. (This was publicised near-simultaneously with Snowden's own 2013 disclosures.) https://www.eff.org/cases/hemisphere

• 2006: Mark Klein and the Room 641A revelations concerning AT&T's beam splitters: https://en.wikipedia.org/wiki/Room_641A

• 2005, William Binney and J. Kirk Wiebe, NSA whistleblower, warrantless surveillance. https://en.wikipedia.org/wiki/William_Binney_(intelligence_official)

• 2004, Russell Tice, NSA surveillance including of congressional members. https://slate.com/news-and-politics/2006/01/why-nsa-whistle-blower-russ-tice-may-be-right.html

There were very strong suspicions around the TIA (total information awareness) and USA PATRIOT ACT (2003, 2001). I recall much chatter about this at the time, and the related FISA court, though little by way of specific details of technological measures and methods involved.

Carnivore, a WinNT workstation-based tool, disclosed ~2000. https://en.wikipedia.org/wiki/Carnivore_(software)

There are telephnic data retention programmes, including MAINWAY (revealed in 2006), containing an estimated over 1.9 trillion call-detail records, and

https://en.wikipedia.org/wiki/MAINWAY

Project ECHELON, with disclosures of varying aspects from 1972 -- 2000. https://en.wikipedia.org/wiki/ECHELON

There are earlier periods, notably addressed by the FBI's own COINTELPRO archives (https://vault.fbi.gov/cointel-pro), though for my purposes I'm considering "modern" projects to be circa 1990 onwards. (COINTELPRO and the Church Committee hearings resulted in substantial changes, at least publically, to US domestic surveillance).

And I've compiled a long list of pre-1990 references of concerns regarding significant technologists who'd warned of the risks of information technology as a tool of surveillance and control, largely as no such list seemed extant: https://toot.cat/@dredmorbius/105074933053020193

I'm well aware that documentation of clandestine and national security issues is difficult to come by, see the TK case for one reason why that is.

But that's also why specific documentation is so valuable and why I'd requested that.
