  1. Que bacana, amigo! vou dar uma olhada no seu projeto também!
  2. Este projeto surgiu com uma simples conversa com um dos diretores da BS2 internet, estamos planejando criar uma ferramenta para bloquear todo o tráfego que não fosse oriundo do Brasil. Dito isso, o projeto apresentado é apenas uma PoC (Proof of Concept) não tem a intenção de se tornar um projeto profissional. Quem administra servidores de hospedagem, sabem que todos os dias recebemos ataques de brute force, negação de serviço, etc. A mitigação desses ataques, quase sempre é realizada com sucesso, visto que as técnicas utilizadas já são conhecidas. Recentemente, comecei a analisar alguns dos IP’s que ficavam bloqueados nos firewalls e pensei em automatizar esse processo, pelo menos para saber de onde estão vindos os ataques. Honeypot Utilizei uma técnica para atrair os ataques, a técnica conhecida como honeypot, se basea na criação de uma máquina para ser atacada. Criei uma máquina na Amazon Web Services com o serviço SSH exposto para a internet, não passou muito tempo os ataques começaram a surgir. O primeiro IP que apareceu no meu mapa era um relay da rede TOR que estava hospedado na França, fiquei um pouco surpreso, estava esperando algo vindo da Rússia ou China. Duas semanas depois, eu já estava recebendo ataques da China, Japão, Coréia do Sul, etc. Acho que dos seis continentes existentes na terra, só não recebi ataques da Antártida e da Oceania. Montando o projeto Eu utilizei o fail2ban para bloquear os ataques que eu recebia, todos os bans eram permanentes, para manter o mapa cada vez mais cheio. Talvez, a única “ferramenta” que vocês não conheçam, seja o geohash, um sistema para gerar um código único, baseado na latitude e longitude. Foi o geohash que permitiu que os pontos aparecessem no mapa. Para salvar os valores, ip, latitude, longitude, geohash, usei um banco de dados muito simples e rapído, chamado InfluxDB e o grafana para consultar os dados no InfluxDB e popular o mapa. É uma solução simples, porém, a apresentação ficou muito elegante. Como podem notar na imagem acima, a china ultrapassou rapidamente qualquer outro pais. Esses chineses, rsrs. Investigando alguns IP’s A china foi a campeã de bloqueios, o curioso é que todos os IP’s bloqueados estavam dentro de um conjunto. Eu recebi uma série de ataques vindo de uma rede 222.186., todos os IP’s pertence a mesma organização CHINANET jiangsu province backbone. Lista completa dos IP’s chineses vindo da mesma rede. 222.186.190.2 222.186.180.8 222.186.175.150 222.186.175.148 222.186.175.183 222.186.175.163 222.186.175.202 222.186.173.142 222.186.175.154 222.186.169.192 222.186.173.215 222.186.180.223 222.186.175.167 222.186.173.154 222.186.175.169 222.186.180.41 222.186.173.226 222.186.180.6 222.186.175.212 222.186.180.147 222.186.175.215 222.186.175.217 222.186.175.182 222.186.169.194 222.186.175.216 222.186.175.151 222.186.173.238 222.186.173.201 Agora, falando do Brasil, recebi alguns ataques vindo de São Paulo, Rio de Janeiro e Goiania.

  3. São comuns em sistemas baseados em BSD. Talvez o dispositivo em roda algum BSD por baixo dos panos, rs.
  4. Muito obrigado pela aula, Fred hahahaha vou tentar aplicar isso: Abraço! Inclusive, saudades do grupo C/asm do facebook hahahaha
  5. Olá, pessoal, recentemente adquiri interesse em desenvolvimento de exploits entre outros assuntos relacionados. Ainda sou muito iniciante e estou tendo algumas dificuldades para entender alguma peculiaridades. Fiz um código em C utilizando assembly inline e o mesmo não estava compilando, achei uma solução para isso na internet que seria execução o seguinte trecho de código. int (*ret)() = (int(*)())sc; ret(); Minha dúvida é: qual a diferença entre usar o __asm__("jmp sc") e usar a solução acima? Codigo completo /* 8049000: b8 01 00 00 00 mov eax,0x1 8049005: bb 01 00 00 00 mov ebx,0x1 804900a: cd 80 int 0x80 8049000: b8 01 00 00 00 mov eax,0x1 8049005: bb 00 00 00 00 mov ebx,0x0 804900a: cd 80 int 0x80 */ #include <stdio.h> int main() { unsigned char sc[] = "\xb8\x01\x00\x00\x00" "\xbb\x01\x00\x00\x00" "\xcd\x80"; printf("Shellcode length: %d\n", sizeof(sc)); //__asm__("jmp sc"); int (*ret)() = (int(*)())sc; ret(); }
