Towards Complete Node Enumeration in a Peer-to-Peer Botnet

This study presents an effective approach for complete node enumeration in peer-to-peer (P2P) botnets, specifically targeting the Storm botnet. It introduces PPM (Passive P2P Monitor) for routing node collection and FWC (Firewall Checker) for sending queries. Experimental results demonstrated PPM’s efficiency over a 20-day period using 256 nodes. The analysis reveals the challenges faced due to message routing and source address spoofing. Ultimately, the research underscores PPM’s capability in identifying new nodes within the Storm network, providing valuable insights for P2P security measures.

  3. INTRODUCTION • PPM-Passive P2P Monitor -collection of a “routing only” nodes in the P2P network • FWC-FireWall Checker -send back two query packets one from the sensor and one from another IP • Storm Botnet -Overnet Protocol • Crawler -sending look-up requests -get-peerlist protocol

  4. ARCHITECTURE • Expected Problems and Fixes -PPM cannot identify a new node, if Storm botnet does not send messages to it -PPMis its lack of source address spoofing detection

  5. ARCHITECTURE • Implementation Details 1. A Storm node in the bot network sends a request to one of our PPM 2. PPM replies to the request and sends another request to that Storm node 2’. At the same time, PPM also sends a message to FWC telling it to send a similar request to that Storm node 2”. Upon receiving this message, FWC sends a request to the same Storm node (same request that PPMsent to that Storm node).

  6. ANALYTICAL AND EXPERIMENTAL RESULTS • Experimental Settings -PPM nodes, the FWC, and a P2P network crawler -deployed 256 PPM nodes -collected from 20 days -deployed 16 virtual machines infected each of them with Storm

  7. ANALYTICAL AND EXPERIMENTAL RESULTS

  8. ANALYTICAL AND EXPERIMENTAL RESULTS

  9. ANALYTICAL AND EXPERIMENTAL RESULTS

  10. ANALYTICAL AND EXPERIMENTAL RESULTS

  11. ANALYTICAL AND EXPERIMENTAL RESULTS • Probability of PPM receiving a random message -Search is a message used in routing to find the replica roots - GetSearchResult is a message sent to possible replica roots to get the actual result -Publish is a message meant to publish binding information

  12. ANALYTICAL AND EXPERIMENTAL RESULTS

  13. ANALYTICAL AND EXPERIMENTAL RESULTS

  14. ANALYTICAL AND EXPERIMENTAL RESULTS

  15. ANALYTICAL AND EXPERIMENTAL RESULTS

  16. CONCLUSION • PPM as an enumeration method for the Storm peer-to-peer botnet is efficient • analyzed the differences in enumeration results from the PPM and a crawler
