PSDecode is a powershell script module for decoding powershell obfuscated scripts. This tool removes layered obfuscated techniques like strings concatenating and string replacement.

From Malware Analysis perspective adversaries frequently employ encoding and obfuscation techniques to camouflage their downloader scripts, aiming to evade detection and hinder analysis by security professionals. By encoding and obfuscating their scripts, adversaries can make it difficult for security solutions to identify and analyze the malicious intent embedded within the code.

Adversaries encode and obfuscate their downloader scripts to enhance their chances of successful infiltration, impede analysis, and protect their techniques. As defenders, it is crucial to know advanced techniques and tools capable of overcoming these obfuscation methods to effectively detect, analyze, and mitigate emerging threats.

Automate Artifact Collection

To use PSDecode, create a directory named “PSDecode” under “WindowsPowerShell/v1.0”

Because employees are the most vulnerable targets for an organization, giving attackers the ability to compromise their targets by preying on human weakness like emotions. For this reason, adversaries plan their assaults intelligently by using phishing attacks.

In this demo, we will tackle about different approach on how to detect and respond to a phishing incident using a memory forensics tool.

Scenario: What if due to fear of getting sanctioned by the organization, an employee trashed a possible phishing email after he/she clicked and downloaded the potential suspicious attachment.

Now, as the analyst we are tasked to perform Incident Response and Digital Forensics on the machine and find some useful evidence of email existence.
