Exploring a New Way to Check Processes: Insights from StackZero

During malware analysis we never stop to stay updated. There's a smart way malware hides by checking out the running processes on a system. We're going to look at a different method to do this, based on some interesting information from VX Underground.

What is Process Enumeration?

Process enumeration is a technique where malware scans and identifies all the active programs on a computer. It helps the malware choose which program to attach itself to, making it harder for antivirus software to detect it. The choice of this process is crucial for malware to operate effectively without being noticed.

A Fresh Approach to Process Enumeration

The new method we're discussing adds a twist to the traditional ways malware tries to hide. It's like a spy learning new tricks to avoid being caught. This makes it even more important for those fighting malware to stay sharp and understand these new tricks.

Key Tools: EnumWindows and EnumDesktopWindows API

These are two tools malware can use to scan the computer. EnumWindows is like a bird's-eye view, scanning everything, while EnumDesktopWindows is more like looking through a magnifying glass at specific areas. Both are used by malware to find the best place to hide and are related to the active windows in the first case and to the active windows on a specific desktop in the second one.

So obviously you cannot have a complete view on all the active processes but it's the price to pay to have a higher chance to be unnoticed.

The Important Role of EnumWindowsProcesses Callback

This function helps the computer system check each application or process one by one. It's like a thorough inspection to find the specific process that the malware is looking for, ensuring the malware remains unnoticed. And it has to be called from EnumWindows and EnumDesktopWindows.

Understanding Callback and Main Functions

Think of the EnumWindowsProc callback and the main function as team members working closely together. Their job is to carefully identify and focus on the particular process that the malware needs to interact with. This collaboration is crucial for the malware to move forward with its plan on the computer.

It's common goal, in the malware context, is to obtain an handle to a target process that will be subsequently used for injection.

Conclusion: Staying Ahead in Cybersecurity

For those of us working to keep computers safe, it's crucial to understand these methods. It helps us prepare better defenses and stay one step ahead of malware.
