Denial of Service Attack Against Bitcoin Network Taking Place
A distributed denial of service (DDOS) is taking place against the bitcoin network and disrupting a number of exchange operations, Blockchain.info chief security officer Andreas Antonopoulos has revealed on Twitter. The attack is taking advantage of the transaction malleability issue we've been hearing a lot about since Mt. Gox mentioned it extensively in an update on withdrawal issues Monday. Antonopoulos says user funds across the network are safe, and Blockchain.info's implementation of a bitcoin wallet is not affected, though the same can't be said for other bitcoin properties, in that....

Georgia-based CampBX has been having issues with their service since at least Thursday of last week, according to tweets transmitted by the crypto-currency exchange. Beginning on the 3rd of July, the company took to social media to report that their service was dealing with a DDOS attack. For those unfamiliar, a DDOS is a distributed denial of service attack. An attack of this nature overwhelms a target server/s with requests, making the service slow or even unreachable by legitimate users. A D-DoS attack is in progress. We are working to mitigate it. - CampBX - Bitcoin (@CampBX) July 3,....
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....
Having issues with BTC-e today? You're not the only one. A number of users in the bitcoin community have reported issues with the exchange, raising fears about the service and whether or not it was operating as-should or not. The root of those issues are a distributed denial of service attack (DDOS), confirms the exchange on their official Twitter account. This isn't the first time this has taken place (nor the last time, we reckon), and it certainly does highlight the community's sensitivity when it comes to service disruptions. You can't blame them, either. After the Mt. Gox debacle,....
