Open Bitcoin Privacy Project Tool TorBan Helps Bitcoin-Over-Tor Stay Anonymous
Kristov Atlas has developed a quick tool called TorBan which can warn of a Bitcoin-over-Tor de-anonymization attack, called the "Luxembourg Attack." The "Luxembourg Attack," first described by University of Luxembourg researchers Ivan Pustogarov and Alex Biryukov earlier this year, involves the use of thousands of Bitcoin nodes and a handful of controlled Tor exit nodes to "de-anonymize" users using Bitcoin over Tor. The Luxembourg research paper, titled "Bitcoin over Tor isn't a good idea" detailed the potential attack. The Bitcoin network has built-in denial-of-service (DoS) attack....

Days after researchers described an attack that could reveal the identities of individuals who used bitcoin over the Tor anonymity network, a privacy advocate has developed a tool to monitor the occurrence of that attack. The tool, TorBan, is a website that gives information about the Tor exit nodes currently connected to the bitcoin network. If all the connections are fresh, users should be wary of a privacy-invading attack like the one described by the Luxembourg researchers, TorBan's creator Kristov Atlas said, adding: "If you see a bunch of new nodes never seen before, and all of the....
The big question is whether or not this software can do the things it claims to do. There has been a lot of talk about Bitcoin and whether or not it is anonymous. Cryptocurrency experts will gladly point out Bitcoin is not anonymous, but rather pseudonymous. For those people interest in de-anonymizing cryptocurrency, however, BitCluster is a solution looking into. This tool has now been open sourced, and users can download the kit, as well as the database, from the website right now. Explaining what BitCluster does it not overly difficult, as this open-source tool is designed to analyze....
Bitcoin has won a Linux award at CeBIT 2014 - Europe's premier tech trade show. The award was handed out at the Linux New Media Awards 2014, where bitcoin was named the 'most innovative open-source project'. The open-minded, open-source community behind Linux has a soft spot for innovation, encryption and apparently privacy. In addition to bitcoin, the audience also decided to hand out further awards to email encryptor GnuPG and the Tor project, along with developers' tool Git. Most innovative of them all. Thousands of Linux enthusiasts and readers of leading Linux publications took part....
Bitcoin is often advertised as an anonymous digital currency that offers a high level of user privacy. People can hide their identities behind a wallet address, and generate additional addresses if needed. But is Bitcoin as anonymous and privacy-centric as uneducated people assume? The answers might surprise you. Right now, there is a decent level of customer privacy in business. But it only exists on a conditional basis. In the current financial infrastructure, any bank can and will disclose any personal information if the government requests it. While this may not be of great concern for....
May Day, May Day, it’s about to get dark. Dark Wallet (Alpha), the bitcoin wallet software that uses the power of encryption and technology of CoinJoin, has been released. The legality of coin mixing services is still unclear, and the fact that some coin mixing services go by names like ‘The Bitcoin Laundry’ and ‘BitLaundry’ does not bode well in the regulatory spotlight. Although, one can argue the right to financial privacy because bitcoin is only pseudo-anonymous. I took my questions to computer security expert, Kristov Atlas, author of Anonymous Bitcoin, to see what he thought. “You’ve....
