I have tried three apps base64 helper base64 TA-base64pl none of them are able to decode the entire string, because as soon as the first null/pad character is read, splunk stops. SOLUTION You can use the following dataweave script to decode it successfully: dw 2.0 import fromBase64 from dw::core::Binaries output text/plain - fromBase64 (ssage replace // with ('/') replace /-/ with ('+') replace /\. The command takes an optional action of encode or decode, and a list of fields to work on. 08-13-2018 12:59 PM I am trying to decode base64. Accepts a base-64-encoded string version of a command. These are the methods that I use to both encode and decode in my daily work. After adding the Splunk Decrypt addon 2655 to decode powershell encoded scripts I ran into a problem. This tutorial builds on the work of others with some new cleverness to provide an efficient decoding of powershell commands for threat hunting.

Description Adversaries may use Obfuscated Files or Information to hide artifacts of an intrusion from analysis. Overview Adds a base64 command to the Splunk search language. In this article, I will share both a simple and a slightly more advanced understanding of Base64 encoding. If you already have powershell event logs in Splunk and want to decode the base64, this may help. You can retrieve a list of the valid character encoding specifications by using the iconv -l command on most nix systems.
SPLUNK BASE64 DECODE SOFTWARE
Next, let’s use the -d or -decode option to decode a file from base64 back to its original format: base64 -d output-file.txt This is my input file The decoded contents are shown as output in our terminal. If a source doesn't use UTF-8 encoding or is a non-ASCII file, Splunk software tries to convert data from the source to UTF-8 encoding unless you specify a character set to use by setting the CHARSET key in the nf file. Downloading Base64 encode or decode fields using Perl instead of Python Or to output the encoded data into its own file: base64 input-file.txt > output-file.txt.
