A universal EDR bypass built in Windows 10

While studying internals of a mechanism used by all EDR software to get information about processes activities on Windows, we came across a way for malicious processes to disable the generation of some security events related to process interactions. This technique could be used to evade EDR software while performing malicious operations such as process memory dumping, code injection or process hollowing.

Exploiting an io_uring Vulnerability in Ubuntu

This post discusses a use-after-free vulnerability, CVE-2024-0582, in io_uring in the Linux kernel. Despite the vulnerability being patched in the stable kernel in December 2023, it wasn’t ported to Ubuntu kernels for over two months, making it an easy 0day vector in Ubuntu during that time.

توسعه بدافزار C2
توسعه بدافزار یکی از مهارتهایی است که برای شبیه سازی حملات APT بسیار مهم و کاربردی است

طبق MITRE attack و cyber kill chain یکی مراحل C2 است.

https://attack.mitre.org/tactics/TA0011

https://www.lockheedmartin.com/en-us/capabilities/cyber/cyber-kill-chain.html

برای توسعه بدافزار ابتدا نیازمند یادگیری یک زبان برنامه نویسی هستید، زبانی نیاز دارید که بتوانید توسط آن با win32 API کار کنید

زبان های پیشنهادی

c++

python

rust

کتاب ها:

https://institute.sektor7.net/rto-maldev-intermediate

https://maldevacademy.com/

https://www.udemy.com/course/offensive-rust/

https://www.udemy.com/course/offensive-csharp/



قدم بدی نیازمند یادگیری win32 API هستید تا بتوانید

Process Manipulation, Memory Manipulation, Networking, DLL Injection

همچنین انواع تکنیک های injection یاد بگیرید:

DLL Injection, Process Hollowing, Reflective DLL Injection, Thread Injection, AtomBombing, APC Injection

لینک زیر ببینید:

https://github.com/RedTeamOperations/Advanced-Process-Injection-Workshop

c2 نیازمند یک protocol communication هست

http/https, DNS, ICMP

نیازمند یادگیری کار با Encryption

AES, XOR, RC4, RSA, ECC, ChaCha20

بعد از اینکه c2 خودتان را توسعه دهید تازه باید به دنبال دیباگ کردن و همچنین دور زدن Anti Virus و EDR باشید برای اینکار نیازمند تکنیک و ابزار Debugger هستید:

IDA Pro,OllyDbg and x64dbg,WinDbg,Ghidra,Immunity Debugger
