Permanent link Tool: Aria-body loader

NamesAria-body loader
Description(Check Point) The functionality of the Aria-body loader has not changed significantly since 2017, but the implementation varied from version to version. This loader appears to be specifically created for the Aria-body backdoor.

Overall, the loader is responsible for the following tasks:

• Establish persistence via the Startup folder or theRun registry key (some variants).
• Inject itself to another process such as rundll32.exe and dllhost.exe (some variants).
• Decrypt two blobs: Import Table and the loader configuration.
• Utilize a DGA algorithm if required.
• Contact the embedded / calculated C&C address in order to retrieve the next stage payload.
• Decrypt the received payload DLL (Aria-body backdoor).
• Load and execute an exported function of the DLL – calculated using djb2 hashing algorithm.
