by Robert Bailey
October 9, 2023

HackTool:Win32/Keygen is a classification used by antivirus software, including Microsoft Defender Antivirus, to identify a specific type of malware called a keygen or key generator. Keygens are software tools or programs designed to generate valid license keys or activation codes for various software applications, typically circumventing the legitimate licensing mechanisms implemented by software developers.

While HackTool:Win32/Keygen itself is not inherently malicious, it is often associated with illegal activities, such as software piracy or the unauthorized use of copyrighted software. Keygens are commonly utilized to illegally activate software without acquiring a valid license, enabling users to utilize the software without paying for it.

The files reported as Trojan:Win32/Vindor!pz may not necessarily be malicious. If you are uncertain whether a file is malicious or a false positive detection, you can submit the affected file to https://gridinsoft.com/online-virus-scanner for scanning with a free online antivirus engine.

However, the risks of HackTool:Win32/Keygen consist not only of legal prosecution. As such programs are not open-source and lack a digital signature, there is no way to be sure it does not have any malicious code inside. And since they are mostly free, the temptation to monetise the keygen creator’s job with malware is especially high.

Utilities that are detected as Win32/Keygen may even have actual functionality. But it can also include a sneaky malware downloading script, that you will start with your hands, thinking you’re launching a keygen. Additionally, such programs commonly ask for admin privileges – which can grant malware with unlimited capabilities.

Keygen Malware Behavior

Click to expand
  • The binary likely contains encrypted or compressed data. In this case, encryption is a way to conceal the virus’s code from antivirus software and virus analysts.
  • The executable is compressed using UPX.
  • Network activity is present in fact, but not in API logs. Microsoft has integrated an API solution directly into its Windows operating system to track network activity for all apps and programs that have run on the computer within the past 30 days. However, this malware manages to hide its network activity.
