SNMP-Brute
A fast SNMP brute force, enumeration, and Cisco config downloader with password cracking capabilities.
What is SNMP-Brute?
SNMP Brute is a Python-based security tool for brute forcing SNMP community strings, enumerating network devices, and downloading Cisco configurations. It automates the process of identifying weak SNMP credentials and extracting sensitive information from vulnerable devices, helping security professionals assess network security.
Penetration testers, security researchers, and network administrators who need to audit SNMP security on Cisco, Linux, or Windows systems.
It combines multiple security tools (Metasploit, John the Ripper, snmpwalk) into a single script, offering fast brute forcing with minimized wait times and integrated password cracking for efficient network assessments.
Overview
Fast SNMP brute force, enumeration, CISCO config downloader and password cracking script.
Use Cases
Best For
- Auditing SNMP security on corporate networks
- Penetration testing engagements targeting network devices
- Identifying weak SNMP community strings on Cisco routers
- Extracting and cracking passwords from downloaded Cisco configs
- Enumerating SNMP information on Linux or Windows servers
- Security assessments requiring rapid SNMP brute forcing
Not Ideal For
- Environments where installing Metasploit, John the Ripper, and other dependencies is prohibited or impractical
- Security assessments focused exclusively on SNMP v3, as the tool only supports v1 and v2c
- Projects requiring a graphical user interface or seamless integration into CI/CD pipelines
- Continuous, large-scale network monitoring, since it's designed for one-off penetration testing scans
Pros & Cons
Pros
Listens for responses during brute forcing to minimize wait times, making it efficient for rapid SNMP enumeration as highlighted in the README.
Automates workflows by combining Metasploit for config downloads, John the Ripper for password cracking, and snmpwalk for enumeration, reducing manual steps.
Supports enumerating Cisco, Linux, and Windows devices using specific OIDs, providing comprehensive network assessment capabilities.
Allows targeting single IPs, IP lists, and adjusting send rates and timeouts for controlled scanning, as detailed in the advanced options.
Cons
Requires Metasploit, snmpwalk, John the Ripper, and snmpstat to be installed and configured, adding significant setup complexity and potential compatibility issues.
Limited to SNMP v1 and v2c, which are outdated and less secure, making it unsuitable for modern networks that have adopted v3 for enhanced authentication.
The README provides minimal usage examples and lacks troubleshooting guides, which can hinder new users in resolving errors or customizing scans.
As a GitHub project that may not be actively maintained, it risks compatibility issues with newer systems or updated versions of required tools.
