Advanced Stealthy Dropper


In short dropper is type of trojans that downloads other malwares and Dr0p1t gives you the chance to create a stealthy dropper that bypass most AVs and have a lot of tricks.

Features


+ Generated executable properties:

  • The executable size is smaller compared to other droppers generated the same way.
  • Download executable on target system and execute it silently..
  • Self destruct function so that the dropper will kill and delete itself after finishing it work
  • Escape disk forensics by making all the files dropper create and dropper also cleans its content before deletion
  • Clear event log after finishing.

+ Framework properties:

+ Modules:

  • Find and kill antivirus before running the malware.
  • The ability to disable UAC.
  • The ability to run your malware as admin.
  • Full spoof by spoofing the file icon and extension to any thing you want.
  • ZIP files support so now you can compress your executable to zip file before uploading.
  • Running a custom ( batch|powershell|vbs ) file you have chosen before running the executable
  • In running powershell scripts it can bypass execution policy
  • Using UPX to compress the dropper after creating it

+Persistence modules:

  • Adding executable after downloading it to startup.
  • Adding executable after downloading it to task scheduler ( UAC not matters ).
  • Adding your file to powershell user profile so your file will be downloaded and ran every time powershell.exe run if it doesn’t exist.
