11:14 Revealed the biggest secret skype | |
The link is the source obfuscated cipher RC4, which is used in Skype for encrypting traffic. Upd with enrupt.com: Posted algorithm is ALL what you need to decrypt the traffic between clients and supernodami. Key no. Altogether. Because this level of obfuscation designed to ensure that others could not make their clients for the record Skype. Therefore, this algorithm has been protected as much as possible. Monopoly Skype, which is no more. Do not worry if the Skype protocol transition, we need just a few days to get it. We will immediately release an update. Our publication does not affect the privacy of phone calls, messages or file transfers. They are protected using AES-256, a key agreement is done by 1024bitnogo RSA. So do not panic) Next month we may be lined with files of that decodes UDP packets Skype and verifies CRC:) Over 10 years of Skype offered us protection, which we nothing do not know. The so-called security through obscurity. Obscurity in this case was very good, because for all this time, almost no one has figured out how it all works, despite the abundance of skaypovskih binaries. And those who were able, for obvious reasons did not publish their achievements. One of Western companies dealing with cryptography, a couple of months ago, flowed findings Skype, which abruptly began to be used by hackers and spammers, Skype launched their abyuzit and as a result, the company has posted them in the universal access. This is not a complete solution. To learn how to listen skaypovsky traffic using this feature, they will tell in Berlin The 27th Chaos Communication Congress (27C3) PS Not all encryption in Skype is a prime and baMost of it is implemented by all the rules. The Skype 7 encryption types talk: Server uses AES-256, supernody and clients use 3 different types of RC4: old TCP RC4, old and new UDP RC4, based on the DH-384 TCP RC4. Clients also use AES-256 on top of RC4. All pretty confusing, but at the conference promises to sort through everything. Well) All the secret, as they say ... Original here. God keep them from habraeffekta. Incidentally, this same firm has developed an algorithm enRupt, which is on the characteristics of Go Large everyone else) about it as some other time. UPD: transferred the source code here | |
