Quote from: QualityMeds on April 29, 2013, 04:09 amI still fail to see how a Ddos attack on a specific .onion site is even possible without knowing the specific server's location. Does this mean that someone has figured out where SR's servers are located? Bandwidth is limited for the Tor server volunteers, correct? Wouldn't an overload of data just make you lose connectivity with the Tor servers you are connected to? Am I wrong? If I'm right, what other possible method could someone have to slow down SR's servers to a crawl? Wow a lot of questions there, hope someone can answer some or all of them...So as I often point out as a disclaimer before I go shooting my mouth off about this, I don't do cracking. All this hacking and DoS rubbish just isn't my thing, but it's kind of related and kind of interesting, so I know a little bit about it. Still: take my words with a grain of salt. I'm no expert in this.There are a ton of ways to perform a denial of service attack. Some cripple a machine by hitting it with too many requests at once that the actual operating system isn't able to handle, some don't try to paralyze the operating system at all but instead try to overload the web server software so that *it* gets crippled, some try to exploit specific vulnerabilities in a database connection so that even if the server software is functioning properly the site is still crippled because the database storing all the information is crippled... It goes on and on. Lots of ways nobody even knows yet, I'm sure. All of these systems are all interacting with each other using dozens of different standards and protocols. It's almost a miracle it works as well as it does to begin with.There are two basic network connection protocols, TCP and UDP. TCP is what you usually think of an internet connection (like to a web page), and it's the connection type that Tor supports. UDP is often used for denial of service attacks, but Tor doesn't even support that protocol. You can't send information using UDP over Tor. Well... I hate to speak in absolutes, but basically it's just not possible.So that's why everyone goes around saying you can't do distributed denial of service attacks via Tor. Because classically speaking, you can't. But a denial of service denies access to a given service. I don't know about you guys, but I'm sure as Hell being denied access to SR's forums. It also doesn't seem to have anything at all to do with the Tor network. The servers themselves are being (almost) crippled by a means other than what people usually are talking about when they say DDoS.If you're really curious what may be going on, you can check out http://mixedbit.org/blog/2013/04/11/dos_attack_on_cdn_users.html -- I don't know that it has anything to do with anything here, but it may give you a better idea how a DoS can be done even with Tor. Or it may just confuse you more, I dunno... either way, there ya go.By the way, I've been on the main Silk Road sight all night. Frankly I don't know what you guys are talking about, SR has been working just fine for me. The forums on the other hand......
