GravityRAT – Purpose and Activity
GravityRAT is a remote access Trojan – this basically means that the threat is not the type of malware that contains one or two malicious files. GravityRAT has a lot of malicious files and folders, which are dropped by it upon infecting the victims. These files may be under different names and may exist in the most often used by malware Windows folders, such as:
After dropping it’s payload, GravityRAT may heavily modify the Windows Registry Editor, starting with attacking the Run and RunOnce registry sub-keys in order to make it’s malicious modules start automatically alongside Windows.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
After doing so, GravityRAT may initiate it’s full potential. For starters, the malware may connect to a remote host from which it may download and run absolutely any type of file on your computer. This is because the GravityRAT malware obtains administrative privileges by interfering with crucial Windows components that are responsible for that.
Among the activities of GravityRAT is to search your computer for any Antivirus programs and decide what to do. If there is danger for the malware’s “cryptor” also known as obfuscation software to be detected, then the malware may take the appropriate actions.
The main purpose of GravityRAT however is to aim at the important documents of your computer, such as:
- PDF types of files.
- Scanned photos.

- Microsoft Excel spreadsheets.
- Images.
- Other often used types of files.
The main goal of GravityRAT does not stop it from doing other information stealing and collection and also other nefarious actions on your computer, like:
- Create copies of itself to fool you into thinking you or your antivirus software has removed the threat.
- Steal your passwords and other important information saved on your PC.
- Copy text from your documents.
- Log the keystrokes you type to steal passwords and other critical data (financial information).
- Download and install other malware on your computer.
- Update it’s obfuscation software to remain hidden for longer periods of time.
- Delete files and damage Windows.
- Control the hardware of your computer. (Eject flash drives, eject CD/DVD drives, etc.)

- Scan for Malware
- Fix Registries
- Remove Virus Files
Step 1: Scan for GravityRAT with SpyHunter Anti-Malware Tool
Step 2: Clean any registries, created by GravityRAT on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by GravityRAT there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.Step 3: Find virus files created by GravityRAT on your PC.
1.For Windows 8, 8.1 and 10.
For Newer Windows Operating Systems
1: On your keyboard press + R and write explorer.exe in the Run text box and then click on the Ok button.
2: Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.
3: Navigate to the search box in the top-right of your PC's screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be "fileextension:exe". After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:
N.B. We recommend to wait for the green loading bar in the navigation box to fill up in case the PC is looking for the file and hasn't found it yet.
2.For Windows XP, Vista, and 7.
For Older Windows Operating Systems
In older Windows OS's the conventional approach should be the effective one:
1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.
2: After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.
3: After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.
Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
