Advanced IP-Intelligence & DNS Monitoring using eBPF

🛡️ Advanced host monitoring and threat detection with eBPF 🛡️

eBPFShield is a high-performance security tool that utilizes eBPF and Python to provide real-time IP-Intelligence and DNS monitoring. By executing in kernel space, eBPFShield avoids costly context switches and offers efficient detection and prevention of malicious behavior on your network through monitoring of outbound connections and comparison with threat intelligence feeds. 🔍



📝 Introduction

Welcome to eBPFShield, a powerful and intuitive security tool for monitoring and protecting your servers. Featuring both IP-Intelligence and DNS monitoring capabilities, eBPFShield utilizes the power of ebpf and python to provide real-time monitoring and actionable insights for identifying and mitigating potential threats.

Say goodbye to constantly monitoring your servers with tcpdump and hello to a more efficient and automated security solution with eBPFShield.

Available for Windows, Linux and Ubuntu.

Feature Roadmap: 📅

  • Automated IP reputation analysis using Machine Learning algorithms
  • Support for IPv6 and non-standard DNS ports for improved coverage and detection
  • Advanced forensics support to support Fileless Execution, Illegitimate Shell, kernel module loading
  • Integration with popular SIEM systems for centralized monitoring and alerting
  • JSON output for easy integration with a UI dashboard
  • Detection of DNS packets on non-standard ports



🚀 Usage

Run python main.py to get started. Out of the box it will not take any action, it’ll just print violations as it sees them.

$ python main.py -h
usage: main.py [-h] [--block {print, dump, suspend, kill}] [--feature {ebpf_ipintelligence, ebpf_monitor}] [--verbose]

optional arguments:
  -h, --help            show this help message and exit
  --block {print, dump, suspend, kill}
  --feature {ebpf_ipintelligence, ebpf_monitor, ml_ebpf, ebpf_antidebugging}
  --verbose

There are four options supported under --features flag:

  • ebpf_ipintelligence: monitor and block outbound connections against IP threat intelligence lists using tcp/udp and ipv4.
  • ebpf_monitor: displays all DNS queries in the system.
  • ml_ebpf: runs decision tree on user/kernel space based on ebpf_wrapper
  • ebpf_antidebugging: Detect possible code injection into another process

There are four actions currently supported via the --block flag:

  • print: the default action, just writes to the screen and that’s it
  • suspend: send a SIGSTOP to the process. This can be useful if you need to keep the process in a state where you can interact with it.
  • kill: kill the process. This may be useful if all you want to do is immediately stop potentially malicious behavior.
  • dump: suspend the process, take a core dump of it for forensics, and then kill it.

If you’re interested in debugging, the --verbose flag may be useful to you. This tells the program to print all connections it sees, not just malicious ones.
