Silk Road's trial just closed and I ran into this old (?) journal of Ross Ulbricht that contains quite a bunch of interesting passages. I think this will turn into a movie.
server was ddosed, meaning someone knew the real IP. I assumed they obtained it by becoming a guard node. So, I migrated to a new server and set up private guard nodes. There was significant downtime and someone has mentioned that they discovered the IP via a leak from lighttpd.
being blackmailed with user info. talking with large distributor (hell's angels).
commissioned hit on blackmailer with angels
got word that blackmailer was excuted
created file upload script
started to fix problem with bond refunds over 3 months old
got death threat from someone (DeathFromAbove)
withdrawals all caught up
made a sign error when fixing the bond refund bug, so several vendors had very negative accounts.
switched to direct connect for bitcoin instead of over ssh portforward
received visual confirmation of blackmailers execution
gave angels go ahead to find tony7
sent payment to angels for hit on tony76 and his 3 associates

market and forums under sever DoS attack. Gave 10k btc ransom but attack continued.
attacker agreed to stop if I give him the first $100k of revenue and $50k per week thereafter. He stopped, but there
appears to be another DoS attack still persisting
paid $100k to attacker
paid the attacker $50k
rewrote orders page
paid attacker $50k weekly ransom
$2M was stolen from my mtgox account by DEA

red got in a jam and needed $500k to get out. ultimately he convinced me to give it to him, but I got his ID first and
had cimon send harry, his new soldier of fortune, to vancouver to get $800k in cash to cover it. red has been mainly
out of communication, but i haven't lost hope. Atlantis shut down. I was messaged by one of their team who said they
shut down because of an FBI doc leaked to them detailing vulnerabilities in Tor.
Had revelation about the need to eat well, get good sleep, and meditate so I can stay positive and productive.
All of this sounds so surreal. He is making a huge amount of money for sure. A million dollars doesn't seem much for him. He is constantly buying servers and he seems to be coding a lot. He also seem like a normal dude.
And here's a funny thread on who's Variety Jones
I was looking for a way to know what are the real differences between magma, sage and pari. I only worked with sage and pari (and by the way, pari was invented at my university!) but heard of magma from sage contributors.
From the sage website: The Sage-Pari-Magma ecosystem
The biggest difference between Sage and Magma is that Magma is closed source, not free, and difficult for users to extend. This means that most of Magma cannot be changed except by the core Magma developers, since Magma itself is well over two million lines of compiled C code, combined with about a half million lines of interpreted Magma code (that anybody can read and modify). In designing Sage, we carried over some of the excellent design ideas from Magma, such as the parent, element, category hierarchy.
Any mathematician who is serious about doing extensive computational work in algebraic number theory and arithmetic geometry is strongly urged to become familiar with all three systems, since they all have their pros and cons. Pari is sleek and small, Magma has much unique functionality for computations in arithmetic geometry, and Sage has a wide range of functionality in most areas of mathematics, a large developer community, and much unique new code.
I also noticed that Sage provides an interface to Shoup's NTL through
ntl. functions. Good to know!
here's an entertaining piece about NSA backdoors through history: http://ethanheilman.tumblr.com/post/70646748808/a-brief-history-of-nsa-backdoors
1997 Lotus Notes: The NSA requested that Lotus weaken its cryptography so that the NSA could break documents and emails secured by Lotus notes. This Software was used by citizens, companies and governments worldwide.
I talked about this one here.
You can get the .xpi on the github repo.
Just open it with Firefox and no restart is needed! (
Ctrl+O in firefox)
For now it's very basic. You will see this icon next to the close button:
Yes I know I should create a custom icon :D but I was too busy coding.
You will then see some basic statistics of the day.
I'm now working on making this page nice with pretty graphics and more statistics (week, month, tracking of the most visited website of the week...).
So if you want to try my plugin, know that it works (so far)! And that you should pay this blog a visit because I'm planning on updating it.
A step by step tutorial showing you how to get admin credentials on a windows machine: http://imgur.com/gallery/H8obU
- reboot in start-up repair mode
- read privacy statement of one menu should open notepad
- thanks to notepad replace
sethc 1 with
- so now when you press 5 times on
shift it will call
cmd instead of
- you know have a shell, use command
net localgroup Administrators to get a list of the admins
net user <ACCOUNT NAME HERE> * to change one account's password.
If you're looking for a "fix", microsoft advise you to turn off sticky keys all completely
And here's another exploit for windows 98
Note that as soon as you can access the hard drive, you don't need to use the first trick and can switch around programs in system32 as you wish (except if windows is encrypted with bitlocker). For example you can do this with an ubuntu live cd and swap
cmd with the
magnifier tool and you will be able to do the same thing.
I always thought I could reduce the amount of time slacking if I could track my time on facebook, reddit, hackernews... like I track my calories intake to reduce my weight. I couldn't find a good firefox plugin for that so I decided to make one.
I'm opensourcing the code right here: https://github.com/mimoo/FirefoxTimeTracker
I'm pretty surprised with Firefox SDK and it's actually easier than what I thought to build a browser plugin. It might also help that everything Mozilla documents is clear and pretty.
At the moment the code successfully logs the time passed on different websites across sessions. It just lacks nice graphs. If you want to try it just wait a couple days until I ship.
A kleptographic attack is an attack which uses asymmetric encryption to implement a cryptographic backdoor. For example, one such attack could be to subtly modify how the public and private key pairs are generated by the cryptosystem so that the private key could be derived from the public key. In a well-designed attack, the outputs of the infected cryptosystem would be computationally indistinguishable from the outputs of the corresponding uninfected cryptosystem. If the infected cryptosystem is a black-box implementation such as a hardware security module, a smartcard, or a Trusted Platform Module, a successful attack could go completely unnoticed.
I've seen implementations of this in the wild, here on reddit (python) and here on lobsters (C#)
Here's a funny topic on CS Theory StackExchange: https://cstheory.stackexchange.com/questions/4491/powerful-algorithms-too-complex-to-implement?newreg=dbe44b3dd8ca41019f6a4a23b9fea6d3
What are some algorithms of legitimate utility that are simply too complex to implement?
