Okay, as many of you know, I am going to present the results of a private research about "Stress Testing" - focusing on Denial-of-Service. Today, while searching for some references to add in my presentation, I found the following message in a "hacker" (?) forum: - "MELHOR FERRAMENTA DE DENIAL OF SERVICE DO MUNDO (BASILEIRA)" (http://www.forum.darkers.com.br/index.php?topic=12674.msg53240;topicseen) Translating it to English: "WORLD'S BEST DENIAL OF SERVICE TOOL (BRAZILIAN)". It is just to let you know: 1. THIS TOOL IS A FAKE. 2. I have no plans to release the source code, nor even after the H2HC 7th Edition. 3. The "T50 Sukhoi PAK FA Mixed Packet Injector Tool" was totally written to work on Linux environment, and has no version to work on Windows environment or any other environment other than Linux. All the beta-testers received binaries of T50 with restrictions, such as: 1. Limited time frame: no one can use it in a time frame bigger than 30 days. 2. RFC 1918 Compliance: no one can run T50 against valid IP addresses, it is only capable to test IANA IP address allocation for private internets (i.e., "10/8", "172.16/12" and "192.168/16"). 3. T50 is not based on any tool publicly available, it uses unique techniques never seen before in any tool. So I have no credits for this code (http://pastebin.ca/1957112). Some coward released it, anonymously, writing my name on it. Shame on you, coward!!! Nelson Brito Security Researcher http://fnstenv.blogspot.com/
