A system previously infected with W32/Pinkslipbot may still be serving as a control server proxy for the malware. Even if all malicious components have been removed by a security product, the system may be vulnerable to attacks if it is publicly accessible over the internet. To help identify this vulnerability, Trellix developed a free port-forwarding detection and removal tool specific to Pinkslipbot. This tool will also detect the Pinkslipbot control server proxy service and will disable (not remove) the service if found.

Pinkslipbot C&C Proxy Checker is a command line tool to detect and remove port-forwarding rules maliciously created by W32/Pinkslipbot on home routers. In addition, the tool can detect and disable the malicious service used to repurpose infected machines as command-and-control servers.

To use this tool, you must have:
To use this tool, open a command-prompt window and execute the program without any parameters like so.
This runs the tool in “Detect ONLY” mode where it finds malicious Pinkslipbot services and portforwarding rules but does not remove them. The screenshot below shows the output of the tool when it finds a malicious service installed on the local machine and port-forwarding rules created on the router.
If no infection is found, your system is not vulnerable and you do not need to do anything else.
However, if the output from your execution looks like the screenshot above, you should run the tool again from an elevated command-prompt and pass the “/del” parameter. This instructs the tool to disable the malicious service and remove maliciously created port forwarding rules on your router. The screenshot below shows the output of the tool when run with the “/del” parameter.
This tool uses “MiniUPnPc”, an excellent open-source library for adding UPnP IGD control point support. Its license is listed as follows.
