Adrian Crenshaw analyzes real-world cases of Tor and I2P users being deanonymized, demonstrating that poor operational security was the primary cause.

Presentation available here: defcon.org/images/defcon-22/dc-22-presentations/Crenshaw/DEF… Dropping Docs on Darknets: How People Got Caught Adrian Crenshaw TRUSTEDSEC & IRONGEEK.COM Most of you have probably used Tor before, but I2P may be unfamiliar. Both are anonymization networks that allow people to obfuscate where their traffic is coming from, and also host services (web sites for example) without it being tied back to them. This talk will give an overview of both, but will focus on real world stories of how people were deanonymized. Example cases like Eldo Kim & the Harvard Bomb Threat, Hector Xavier Monsegur (Sabu)/Jeremy Hammond (sup_g) & LulzSec, Freedom Hosting & Eric Eoin Marques and finally Ross William Ulbricht/“Dread Pirate Roberts” of the SilkRoad, will be used to explain how people have been caught and how it could have been avoided. Adrian Crenshaw has worked in the IT industry for the last seventeen years. He runs the information security website Irongeek.com, which specializes in videos and articles that illustrate how to use various pen-testing and security tools. He did the cert chase for awhile (MCSE NT 4, CNE, A+, Network+. i-Net+) but stopped once he had to start paying for the tests himself. He holds a Master of Science in Security Informatics, works for TrustedSec as a Senior Security Consultant and is one of the co-founders of Derbycon. Twitter: @irongeek_adc

Why it's here

What people say. Recommended as a classic talk showing that darknet deanonymization is almost always due to poor operational security rather than protocol failures.

On “18yo arrested for reporting a bug in the new Budapest e-Ticket system”

In case anyone feels like doing something like that, this talk is worth a listen: link to this video A talk on how Tor users got caught. In a nutshell: it wasn't Tor's fault, but bad OPSEC on the part of the users.

On “Who Deserves This? (2018)”

Most cases are closed on circumstantial evidence. Weird to see the same podcast that hosts freeross information as also hosting bitcoin podcasts. Adrian Crenshaw the security researcher has a good defcon talk on how ross went down for SR. Don't post your tech problems for an illegal service on stackoverflow! link to this video

On “Going dark: online privacy and anonymity for normal people”

…cation analytics'. Javascript and stuff must be disabled of course. Carrying any cell phone, burner or otherwise is out of the question. The reasons are many, but for starters, you don't want to be identifiable as the only person at your location making Tor connections, if you're doing something important. Here are some good points on the subject. link to this video My approach for promoting Tor to regular people around me is…

On “Is Tor still safe to use?”

I remember Adrian Crenshaw doing a speech at Def Con 22 about how people got busted using Tor. Even then he point out in most of the cases, it was bad OpsSec by the person, and had nothing to do with Tor. How applicable do people think this information is now 9-10 years later?

Yup, that's how they got Ross Ulbricht. Idiot used "rossulbricht at gmail dot com" under the same username he advertised silk road. Timpestamp link about Ross: link to this video
