Attack Detection Fundamentals 2021: Azure - Lab #1

This article demonstrates a consent phishing attack in Azure, showing how an attacker can trick a user into granting malicious application permissions to access sensitive resources. The walkthrough covers setting up a lab environment using Terraform, deploying Azure resources, and using the O365 Attack Toolkit to generate a phishing link. Azure AD audit logs are explored to detect the attack and understand the permissions granted during the consent phishing process.

Attack Detection Fundamentals 2021: Azure - Lab #3

This article demonstrates a stealthy method of data collection from an Azure VM by creating a snapshot of a target VM's disk and mounting it to an attack VM. The technique allows accessing sensitive information without directly interacting with the original VM, minimizing detection risks. The lab concludes by highlighting the importance of monitoring Azure activity logs for detecting such lateral movement techniques.

Attack Detection Fundamentals 2021: Windows - Lab #1

This article details a cybersecurity workshop demonstrating advanced Windows endpoint attack techniques for initial access. An HTA-based attack method was developed that drops a DLL and uses registration-free COM activation to execute a malicious payload. The payload involves shellcode injection, AMSI bypassing, and process injection techniques targeting Windows endpoints.

Attack Detection Fundamentals 2021: Windows - Lab #2

This article explores advanced defense evasion techniques in Windows cybersecurity, focusing on API unhooking and ETW bypassing. The lab demonstrates methods attackers can use to minimize their detection footprint during endpoint attacks, such as removing API hooks and disabling event tracing. Techniques include intercepting API calls, unhooking ntdll.dll, and manipulating .NET runtime event tracing to avoid security monitoring.

Attack Detection Fundamentals 2021: Windows - Lab #3

This article explores API hooking techniques for stealing RDP credentials during Windows authentication. The lab demonstrates how API hooks can intercept plaintext login information when users connect to remote desktop sessions. Multiple methods are presented, including using Frida and RdpThief, to extract credentials from the RDP client process.

Attack Detection Fundamentals 2021: Windows - Lab #4

This article demonstrates a technique for stealing browser cookies and saved passwords from a Windows endpoint using Chlonium. The attack involves extracting Chrome's encryption keys and cookie databases to hijack web sessions. System Access Control Lists (SACLs) are explored as a method for detecting and logging sensitive file access during such attacks.

Attack Detection Fundamentals: C2 and Exfiltration - Lab #1

This article demonstrates detection techniques for PowerShell Empire's Command and Control (C2) traffic. Network indicators like default URIs, user agents, and server responses are analyzed to identify potential malicious communication patterns. A Snort rule is developed to detect these specific network traffic characteristics associated with PowerShell Empire.

Attack Detection Fundamentals: Initial Access - Lab #4

This article demonstrates creating a malicious Excel 4.0 Macro with Metasploit shellcode to obtain remote access on a Windows system. The lab walks through generating a Meterpreter payload, setting up a Metasploit listener, and executing the malicious macro. Memory forensics techniques using Volatility are explored to analyze the compromised host and detect stealthy code injection methods.

AVRop VM: A ROP based M/o/Vfuscator VM on a Harvard device

A novel virtual machine (VM) based on Return-Oriented Programming (ROP) was developed for an AVR microcontroller. The VM adapts the Movfuscator concept to a Harvard architecture device, implementing a single ROP chain that can execute different payloads through memory-mapped instruction interpretation. The approach allows for executing varied functionality using the same ROP chain on an embedded device with limited resources.

DefCon16 - Virtually Hacking

A presentation by John Fitzpatrick from MWR InfoSecurity at DefCon 16 explored VMware security vulnerabilities. The talk focused on potential attack vectors in virtualized environments. The full presentation is available for download from the MWR InfoSecurity labs website.
