Threats by #AI:
“We show that large language models can be used to perform
at-scale #deanonymization. With full Internet access, our agent
can re-identify Hacker News users and Anthropic Interviewer
participants at high precision, given #pseudonymous online
profiles and conversations alone, matching what would take
hours for a dedicated human investigator.”

“Deanonymization is a two-step process at heart, involving
profiling an anonymous person from their posts, and then
matching them to a known identity. It’s well-known that large
language models can infer personal attributes from
text on online forums. Given this, it makes sense to
ask: how good are LLMs at full end-to-end deanonymization,
and is this a practical threat to pseudonymous accounts?”

[en] Paper: LLMs can be used to perform at-scale #deanonymization

"With full Internet access, our #agent can re-identify Hacker News users and Anthropic Interviewer participants at high precision, given #pseudonymous online profiles and conversations alone, matching what would take hours for a dedicated human investigator."

"Our results show that the practical #obscurity protecting pseudonymous users online no longer holds and that #threat models for online #privacy need to be reconsidered."

"We demonstrate that LLMs fundamentally change the picture, enabling fully automated deanonymization attacks that operate on #unstructured text at scale."

Note: also check paragraphs "Potential harms" and "Potential benefits".

Large-scale online deanonymization with LLMs

#LLMs can unmask #pseudonymous users at scale with surprising accuracy - https://arstechnica.com/security/2026/03/llms-can-unmask-pseudonymous-users-at-scale-with-surprising-accuracy/ " Pseudonymity has never been perfect for preserving #privacy. Soon it may be pointless." no surprise, alas
LLMs can unmask pseudonymous users at scale with surprising accuracy

Pseudonymity has never been perfect for preserving privacy. Soon it may be pointless.

@nasamuffin precisely that

Thanks for this image (I hope it's yours and permissively licensed!) because it's a good illustration for #Bitcoin and other #Shitcoins in regards to #Privacy, as they are at best just #Pseudonymous and every interaction are deanonymizing.

@adisonverlice even if an #MVNO isn't demanding any #KYC whatsoever (i.e. #prepaid are offered OTC in most juristictions) it's NOT "#Anonymous" but merely #pseudonymous as it's trivial for governments to utilize existing and mandtory "#LawfulInterception" appliances to create that #PII chain.

#PhoneNumber <=> #ICCID (#SIMcard) <=> #IMSI (SIM profile) <=> #IMEI (Phone/...).

So if #Anonymity is important, NONE of these details have to be linked somehow even circumstantial.

  • Bought/paid for the phone/SIM/ a single top-up with ec/CC/PayPal/SEPA/… = busted due to circumstantial connection.

  • Use the SIM in any device? Consider them circumstantially connected forever: #ICCID <=> #IMEI.

  • Same applies to #eSIM|s: #EID <=> #ICCID <=> #IMEI.

Add to the fact that most places have #CCTV, and assume that they'll keep recordings for the maximum permissible duration if not longer and oftentimes even use questionable cloud services and you get the picture.

  • I.e. in Germany the maximum permissible storage duration is 72 hours (if nothing hapoens that warrants a longer storage i.e. burglary/theft/robbery/arson/...) so anonymous top-ups would necessitate paying cash at a place one's not been known at (i.e. some kiosk) and waiting at least >72 hours (and checking on the purchase location) before redeeming the top-up code (i.e. dialing *104*1234567890123456# )...

So any #privacy-based service should never ever & under no circumstances demand a Phone Number!

  • Instead any privacy-focussed service should use #OnionServices, host their own #OnionService or at least #DontBlockTor and allow users to use it via @torproject / #Tor to use and signup. (But don't forget circumstantial connections there either!)

  • Also the less details they want or store and the least traffic they generate the harder it is to correlate traffic & users.

@X00001 yes and I refuse to use any service that demands #PII like a #PhoneNumber, which never was #anonymous but merely #pseudonymous even when it was legal to acquire anonymous (e)SIMs in #Germany...

"Bitcoin is #HARAM." - #UmarVadillo
He questioned the need for #crypto if #dinar & #dirham/ #gold & #silver #coins, deposited somewhere, can be exchanged in a #blockchain, with the crypto only representing the #physical #assets. The problem with that that #Bitcoin tries to solve is that physical assets can be legally #confiscated & the physical transfer can be halted. Bitcoin avoids that by being purely #digital, #decentralized, #pseudonymous and #permissionless.
