How Mark Klein told the EFF about Room 641A [book excerpt]
- mannanj 6mo agoSo, this is an uncomfortable read and comes from my personal experience. I'm posting this here as I haven't yet found great outlets and support for what I experienced, and this thread seems like a good spot. Open to outreach and support and ideas from people. In 2021-2022 I was vocal about the CIA being a terrorist organization (I bet many people adjacently believe similar things and are silent) and this got me attention from them. I posted several things I learned from documentaries and on the web, and from my personal background I think it was enough to trigger something in their system. From that time onwards, people I could best describe as Agents w/behavior that matches what professional interrogators would do kept showing up at public events I was a part of and in the most terrifying scenario also infiltrated my public commune. There's an odd history with the FBI and possibly CIA and communes such as Osho the Bagawan (see, Netflix documentary) and I witnessed firsthand how deceptive, harmful and insidious this was. In some cases I believe substances were put in my food and drink, and in the cases matching that my body would later have adverse reactions with the agent's closely observing my behavior and consistently trying to elicit Black Web conversations. I had to flee and colocate to the familiarity of family and friends since, and only recently 3-years later have I been socializing my experience and writing to my congress and house representatives. That said, that was a month ago and they have yet to provide any substantive relief or support - I asked for assistance and guidance with investigating the intelligence community for misconduct as when they're doing this to Americans without any accountability, it undermines the integrity of our Country and I believe our national security. It brings into question who they are really serving. I'm no terrorist, even if I call you one and my skin color is brown and matches what the media-funded-by-the-CIA tells you to believe. I want this story documented and heard, believe what you will, though I leave you with the story that "We know our intelligence community does unethical things, its part of what we've given them the responsibility to do so we ourselves don't have to, and now when that unethical thing has happened to you or someone you know what do you do? What do you do when everyone you turn to for help gaslights you and tells you that surely did not happen? Find proof that the organization whose job it is to go undetected, did indeed do that thing to you." I ask for some empathy and understanding, please.
- mannanj 6mo ago2nd post here. When I share posts matching particular phrases and labels, on HN, I've noticed them get downvoted as though by an algorithm. Would anyone be surprised if the agencies are themselves running bots, algorithms and accounts to affect visibility of discourse on threads like these?
- rkomorn 6mo ago> as though by an algorithm How can you tell the difference between an algorithm and topics genuinely being consistently unpopular, though? > Would anyone be surprised if the agencies are themselves running bots, algorithms and accounts to affect visibility of discourse on threads like these? On HN specifically? Yeah. On actually popular platforms? No.
- direwolf20 6mo agoI run a HN voting algorithm and opinion manipulation system across a few hundred accounts - only a few on any individual post. I use residential proxies to prevent correlation. The account I'm using right now to confess this to you is one that's already been burned. Downvoting this comment is funny, because it's a burned account anyway, so not hurting me, and you want less people to know this fact about HN?
- rkomorn 6mo agoNot sure what your point is?
- alwa 6mo agoDo you represent an agency?
- Karrot_Kream 6mo agoTry it, it's really not that hard. I feel bad saying this and I don't do anything like this anymore but I did make a few accounts behind residential IPs that posted HN popular sentiments on topics that were actually factually incorrect and got a lot of upvotes pretty quickly. I stopped because I felt icky with how corrosive the whole thing could end up being. This was a while ago so not sure if new user sign up has become more difficult. It turns out that open web forums are mostly emotional places and often the most inflammatory or in group opinions rise to the top. With that knowledge, manipulation isn't that tough.
- throwworhtthrow 6mo agoBeware, this is a book excerpt rather than a standalone blog post, so it ends on a cliffhanger. Still a fun read.
- onei 6mo agoThere's more info about the outcome in [1]. Long story short, the US government passed a law (whilst this case was being litigated) that let AT&T off the hook. [1]: https://en.wikipedia.org/wiki/Hepting_v._AT%26T https://en.wikipedia.org/wiki/Hepting_v._AT%26T
- autoexec 6mo agoWhile I was upset to hear how that ended, it's also unfair to expect a company to refuse when the government shows up with guns, takes over a part of your offices, and tells you to stay out of their way and never tell anyone what they are doing or else you'll be killed or sent to a secret torture prison for the rest of your life. That's not a situation that's supposed to happen in a free country, but here we are. If you're handed a gag order by the federal government and can't even tell your lawyers about what happened what options does a company have? How many CEOs and low level employees should we expect to volunteer to have their lives destroyed by refusing to cooperate with the government's illegal surveillance schemes? At&t may not have been coerced quite that aggressively, but these kinds of problems need to be addressed by people other than the private companies who are themselves victims of government oppression. Having said that, not every company is a totally unwilling participant either. There are companies who are happy to make a lot of money by selling our private data to the government. ISPs and phone companies even bill police departments for things like wiretaps and access to online portals where they can collect customer's data. State surveillance (legal or otherwise) shouldn't be allowed to become a revenue stream for private corporations. In fact it should be costly. Considering the massively disproportionate amount of influence corporations have over our government (mostly as a result of their own bribes) it's tempting to want to make compliance so costly to companies that they're compelled to try to use some of that influence to stop or limit domestic surveillance by the state, but honestly I doubt that even they have enough power to stop it. Snowden showed us that even congress doesn't have the power to regulate these agencies. The head of the NSA, under oath, lied right to their faces by denying that their illegal wiretapping scheme even existed. You can't regulate something you aren't allowed to know exists. He also faced zero consequences for those lies which tells us that he's basically untouchable. Obama was elected on campaign promises that he would end the NSA's domestic surveillance programs. Obama was an expert on constitutional law and taught courses on it at the University of Chicago. He spoke out passionately about how unconstitutional and dangerous such programs were. After he was elected his stance quickly changed. He not only started publicly praising the NSA, he actually expanded their surveillance powers. Maybe the NSA showed him a bunch of top secret evidence that scared him enough to make him willing to accept the dangers of their surveillance despite knowing the risks and unconstitutionality. Maybe the NSA strong-armed him. Either way, not even the US president had the power to stop the NSA. It's pretty unreasonable to expect that AT&T would.
- tedd4u 6mo agoThis is literally old news - contemporaneous with Snowden, Prism, etc. in early 2000s. Go read about the current Section 702 / FISA authorization renewal battle about which Senator Wyden recently said: “I strongly believe that this matter can and should be declassified and that Congress needs to debate it openly before Section 702 is reauthorized,” Wyden said in a Senate floor speech last month. “In fact, when it is eventually declassified, the American people will be stunned that it took so long and that Congress has been debating this authority with insufficient information.” Some articles: https://time.com/article/2026/04/27/fisa-fbi-spying-surveillance-fisa-court-congress-wyden/ https://time.com/article/2026/04/27/fisa-fbi-spying-surveill... https://www.motherjones.com/politics/2026/04/trump-congress-fisa-spy-court-fbi-bill/ https://www.motherjones.com/politics/2026/04/trump-congress-...
- Calebp 6mo agoWell, this report to EFF happened in Jan 2006, and the Snowden/Prism leak happened in 2013, so at the time, it was in fact not "old news". I don't think Prism was even in operation until 2007. https://en.wikipedia.org/wiki/PRISM https://en.wikipedia.org/wiki/PRISM https://en.wikipedia.org/wiki/Snowden_disclosures https://en.wikipedia.org/wiki/Snowden_disclosures
- dylan604 6mo agoECHELON pre-dates Prism by several decades
- Barbing 6mo agoThank you for the links! It’s good to understand the new. Also of course good to understand where we came from, imagine a number of users are hearing about PRISM for the first time with this post.
- flordiaman2026 6mo agoSame stuff different day. The United State's laws do not allow for direct domestic spying or something to that effect so they use Five Eyes anglosphere intelligence alliance marketplace as a loop hole. Since Reed Elsevier plc aka "RELX" has purchased LexisNexis who had purchased Seisint, Inc and the technology for Flordia's Multistate Anti-Terrorism Information Exchange Program "MATRIX", which was shut down due to privacy concerns by congress, it is only logical that the data aggregation technology is being used in full force now. There seems to be no other way but to allow 100% technology and communication introspection by the government to stop terrorism.

SAS proved to be too great of a temptation for Mitnick, who desperately wanted to wield the power that the testing system could afford him. Then of course other people started finding similar black boxes at other telecoms and data centers. Ghosts in the wire (his book) mainly focuses on the FBI using the system for wiretaps. And if they can, I'm sure the NSA could just as easily.
- esafak 6mo agoThanks. SAS = Switched Access Services
- razakel 6mo agoEven an office PBX has listen, whisper and barge. Why wouldn't a telco-grade switch have it?

- Spooky23 6mo agoIronically from the perspective of 2026, the actual "conservative" conservatives were the key opponents. The "total information awareness" and national ID efforts were really killed by the conservatives in congress. The "neocons" and moderate/conservative democrats were mostly fine with both.
- bigyabai 6mo ago> The problem is that modern Americans politicize everything. Everything is political. Electric cars, crude oil, rocket launches, rare earth metals, cargo transportation, public transportation, housing, taxation, data, compute... which of those aren't political? The problem is Americans believing obvious lies like "Privacy is a human right" and "Don't be evil" and then blaming the government instead of themselves.

- HocusLocus 6mo agoI think Perfect Forward Secrecy has a great deal to do with how things have turned out. In the days of Room 641A, copying and diverting fiber traffic to somewhere like Utah even before it could be read, would have conferred an advantage if it was encrypted (and important enough for other attacks like black bag jobs on servers). PFS has turned ephemeral encryption into the garbage it deserves to be.
- zuzululu 6mo agoInstances like this is a powerful statement that truly free and democratic governance is not sustainable in the long run with technological advancements. We are basically trading marginal comforts from new technology in the short run for political freedom in the long run and the latency is decreasing. The difference is overt governance of this nature is vilified and amplified in the media and the covert governance is insulated and critics marginalized.
- blurbleblurble 6mo agoThey're sustainable but require major cultural revolution to keep up.
- moron4hire 6mo agoThat's what Jefferson meant by "blood of Patriots."
- bsimpson 6mo agoSo much of surveillance should be blatantly illegal/unconstitutional, but I really don't understand how there can be such a thing as documents that are illegal to possess.
- dylan604 6mo agoTo think a group of people are not going to expend effort in learning about their adversaries is just naive at best. At some point, those adversaries are going to infiltrate your people. The only way to attempt to monitor them would mean you now have the means to monitor your own people. I'm not saying I'm for this, but just acknowledging that it is only inevitable. You can hope for moral people, but that's farcical.
- wawaWiWa2 6mo agoIf the documents are classified. And you dont know the levels of it. I would never hand them over. As i dont know who is cleared. And wait for the court to decide what should i do with them. Or meet the president and hand them personally. By the good semeriton, should protect the lawyes, as they did their best to hold the secret. I am no lawyer .
- anonymousiam 6mo ago"One big change impacting surveillance was clear: Prior to September 11, the U.S. had what could reasonably be called a “wall” separating foreign surveillance for national security purposes done by the NSA from domestic surveillance for law enforcement purposes done by the FBI." It turns out that the above statement is not entirely correct. I was aware of this rule at the time (early 90's), and was very surprised to find that it had been routinely violated for at least a decade. Unlike Snowden, I kept this to myself because I had signed (many) NDAs with the US Government.
- dylan604 6mo ago> Unlike Snowden, I kept this to myself because I had signed (many) NDAs with the US Government. You say this like you are proud of it. Admittedly, I cannot say what I would do in that situation as I've never been in that situation, but I'd hope I'd have the fortitude to speak up on it. Having employees/contractors doing tasks that are illegal just because they came from the higher ups is no different than soldiers refusing illegal orders. Quitting would be the least of the moral options. Speaking up would be higher up the complicated options.
- anonymousiam 6mo agoI'm not proud of it at all. The revelation was startling to me, and I was pretty unhappy about it. It was done in the name of "stopping bad people from doing bad things", but it was still illegal (at least in the white world). Snowden had the same dilemma. He was asking the NSA lawyers about the legality of their programs, and he never got an honest answer. Quitting would not have stopped the activity, and disclosing it would have subjected me to the same treatment that Snowden got. (Years later, I heard an NSA program manager boasting that they would keep asking different government lawyers for an opinion on the legality of proposed programs until they got the answer they wanted. This was after Snowden's revelations.) Pretty much everyone in CIA has a "ends justify the means" philosophy. It's easy to fall into that trap when you learn about all the devious things our enemies are doing. Apparently EOs have been used to circumvent the constitution for quite a while.

- nickburns 6mo agoarpwatch running on an edge router of mine tells me that there's a host with a DoD-registered IP address connected to my (major US) ISP network segment, which I know for a fact contains both business and residential subscribers. I port scanned it when I first discovered it just to say 'hello', and I have little doubt that a dragnet surveillance apparatus lives on the other side of that firewall. Governments have utilized clandestine wiretaps for as long as there have been wires. Bad guys and the children and all that. Not to mention, what an advantage that people think you're kooky when you talk openly about this stuff!
- colechristensen 6mo agoThe DoD also just does an incredible amount of stuff. It is entirely possible that there's just a satellite office for this or that nearby.
- nickburns 6mo agoLong tentacles indeed.
- ZephyrP 6mo agoA long-forgotten machine on a DoD network sounds like the kind of host that could serve for idle scanning or any other technique using a forged source address and a predictable dummy host; I imagine that arpwatch takes a view of network security focused on classifying frames and less on connection behavior.
- bigfatkitten 6mo agoThis post makes no sense whatsoever, for a whole lot of reasons. 1. If this were some covertly installed device, would it have a government attributable IP address? 2. If it were being used for surveillance, why would it be visible at all, instead of being on the other side of a passive optical tap? 3. If it’s really on the same broadcast domain as you, and on some other IP subnet, how can you talk to it? 4. You can configure a device on a network to use any IP address. Why do you think that means it belongs to the government?

- hungryhobbit 6mo agoIsn't AI both the problem ... AND the solution here? True, you can't publish a book anonymously anymore: that ship seems to have sailed. But if you want to publish a political piece or anything else potentially "substantive", can't you just ask AI to rewrite it for you? Instant anonymization!
- trinsic2 6mo agoWhat about the chat conversation from you asking it to write it?
- hungryhobbit 6mo agoLocal LLM.
- autoexec 6mo agoAI doesn't seem like it'd be much help at all. Unless the AI is 100% offline and locally hosted there's a record there. Also generating text isn't really the hard part of being anonymous. You also have publish it somewhere, and somewhere it will be seen, and that also means a trail back to you. Most of the time the information you have to share, especially anything verifiable, will be traceable back to you. That's the problem with knowing something very few people have the access to know. Anyone who does know will be one of a very small number of people. If what you're telling the public isn't at least somewhat verifiable you're just another anonymous/random person spewing unconfirmable conspiracies and you should expect to be treated that way. No respectable publisher is going to print crazy unsourced manuscripts filled with unverifiable claims. The internet is already filled with people doing that who rightly get ignored making that a very crowded space. The ability for AI to push out massive amounts of unconfirmable conspiracies at rates that were previously difficult to achieve is only going to make the problem worse.

- badlibrarian 6mo agoI suppose this is as good a place as any to dump this. In 2002, I was hosting a 1U server in downtown Los Angeles. No cages, minimal security, pretty sure I just walked in. Crash carts sat unattended, usually a screen filled with porn and a cable running on the floor to the nearest tap. I got the feeling that many of the techs were hosting porn sites as a side gig. On my second visit, in plain sight, was new construction. A corner of the room with what looked like four inch fiber bundles going in and out. One dusty, one fresh. Taped dry-wall, unpainted. If the door wasn't so fancy you'd never look twice. Is that...? Dude grimaced and nodded.

- ProllyInfamous 6mo ago>fiber bundles going in and out I worked data centers for my IBEW apprenticeships — during Snowden revelations — and it was definitely "confusing" knowing that all the technology they said didn't exist existed. "Black, LLC" didn't officially exist/make connections among our clientele. Unless you were actively vandalizing our public infrastructure, I never questioned anybody's presence/activities on our datafloors. Probably security is tons better now, but the social entries are still most-commonable.

But here’s the broader, less talked about thing that privacy is for—one that has animated my work for thirty years: privacy is a check on power. Privacy limits the power of individuals over each other. It limits the power of governments over us. It also limits the power of corporations over us.
