Picus Security Details Red Teaming Attack Scenario Steps

Picus Security has released a detailed guide on constructing red teaming attack scenarios, with the initial installment focusing on bypassing security controls. The company, specializing in security testing, explains the process of creating and executing these scenarios to evaluate the effectiveness of existing security measures.

According to Picus Labs, attack scenarios are structured sequences of techniques, tactics, and procedures (TTPs) that adversaries use to achieve their objectives. Developing these scenarios is a crucial part of red team operations, often requiring weeks of planning to select appropriate TTPs that mimic real-world threats.

The published guide outlines a specific attack vector that begins with a user downloading a malicious fake installer disguised as legitimate software. Once executed, the installer deploys malicious BAT and DLL files. The DLL component employs Common Language Runtime (CLR) Hooking to bypass security controls, allowing it to download and execute a meterpreter payload while evading detection.

This method involves injecting the payload into a legitimate process, such as werfault.exe, under the guise of another system process like spoolsv.exe. The technique also incorporates methods to prevent security analysis and ensure the malicious code runs undetected. Picus Security aims to provide practical insights into the design and development phases of such attack scenarios for security professionals.
