Process Ghosting

This article describes a new executable image tampering attack similar to, but distinct from, Doppelgänging and Herpaderping. With this technique, an attacker can write a piece of malware to disk in such a way that it’s difficult to scan or delete it — and where it then executes the deleted malware as though it were a regular file on disk. This technique does not involve code injection, process hollowing, or Transactional NTFS (TxF).

aesKrbKeyGen

Script to calculate Active Directory Kerberos keys (AES256 and AES128) for an account, using its plaintext password. Either of the resulting keys can be utilized with Impacket's getTGT.py to obtain a TGT for the account, provided it is configured to support AES encryption.

CRLF OneLiner

A simple Bash one liner with aim to automate CRLF vulnerability scanning. This is an extremely helpful and practical One liner for Bug Hunters, which helps you find CRLF missconfiguration in every possible method. Simply replace the links in subdomains.txt with the URL you want to target. This will help you scan for CRLF vulnerability without the need of an external tool. What you have to do is to copy-and-paste the commands into your terminal and finger crossed for any possible CRLF.

Bash OneLiner:
input='CRLF-one-liner/subdomains.txt';while IFS= read -r targets; do cat CRLF-one-liner/crlf_payloads.txt |xargs -I % sh -c "curl -vs --max-time 9 $targets/% 2>&1 |grep -q '< Set-Cookie: ?crlf'&& echo $targets '[+] is vulnerable with payload: '%>>crlf_results.txt||echo '[-] Not vulnerable: '$targets";done<$input

RefleXXion

RefleXXion is a utility designed to aid in bypassing user-mode hooks utilised by AV/EPP/EDR etc. In order to bypass the user-mode hooks, it first collects the syscall numbers of the NtOpenFile, NtCreateSection, NtOpenSection and NtMapViewOfSection found in the LdrpThunkSignature array.

Cobalt Strike, a Defender’s Guide

In this research, exposes adversarial Tactics, Techniques and Procedures (TTPs) as well as the tools use to execute mission objectives. In most of cases, the threat actors utilizing Cobalt Strike. Therefore, defenders should know how to detect Cobalt Strike in various stages of its execution. The primary purpose of this articles is to expose the most common techniques from the intrusions track and provide detections. Having said that, not all of Cobalt Strike’s features will be discussed.

FunctionStomping

This is a brand-new technique for shellcode injection to evade AVs and EDRs. This technique is inspired by Module Stomping and has some similarities.The big advantage of this technique is that it isn't overwritting an entire module or PE, just one function and the target process can still use any other function from the target module.
