Here's my journey/blog of an entire wasted day on reversing the NTAPI call and the internals of ntdll!LdrpVectorHandlerList to write my own RtlpAddVectoredExceptionHandler from scratch. The code is hosted on my git.

Call it the biggest #NTLM #password database or monstrous #MD5 leak, but on, you can find precomputed datasets for various wordlists and different hashes - all free!
FYI: all_in_one.latin.txt for NTLM contains 26.5 billion pairs of hash:password inside!🔥

Hi! We'd like to share our new research with you. You've probably heard about COM Hijacking, but we've found another way of persistence via COM. Typelib! Read the article here:

Happy to share another open source project- An x64 position-independent shellcode stager that validates the downloaded payload stage prior to execution. Integration with Cobalt Strike out of the box. Check out Secure_Stager here:

I'm thrilled to share my latest project: AuthStager. This is a proof-of-concept tool that generates a shellcode stager with authentication.
Shout out to @MalDevAcademy, which is hands down the best resource to learn maldev.

Mist from @hackthebox_eu is just a monster active directory challenge. My favorite parts were exploiting PetitPotam with ntlmrelayx to relay into LDAP access on the DC, enumerating Defender exclusion directories, and exploiting ESC13.

Did you know attackers can register scheduled tasks configured with a custom handler (COM) to hide the full path of their payload? In my revisited post I explore (source code) how it is possible to register a task using the IComHandlerAction interface:

This has been one of my favorites for a while, but now it's time to let it go.
Here's my preferred way of getting the KeePass db that we often hunt for:
downgrade the executable to version 2.53, use CVE-2023-24055 and wait for the busy admin to trigger the dump of the database.
The target can remain clean and you can simply check for the dump creation.
KeePass version 2.53 can still open kdbx created with the version 2.57 and if using a proper xml the user will likely notice nothing.
Update alerts can also be disabled within the xml.

Лайфхак, как найти офсеты до интересующего символа в пачке PE разных ревизий Windows

1. Идем на winbindex.m417z.com, ищем нужный бинарь.
2. Сохраняем страничку локально (нормальной апихи не завезли, а результаты формируются на клиент сайде).
3. Граббим версии и ссылочки на загрузку (pup в помощь):

curl -s 'http://127.0.0.1/ntdll.dll%20-%20Winbindex.htm' | pup 'td:nth-of-type(5) text{}'
curl -s 'http://127.0.0.1/ntdll.dll%20-%20Winbindex.htm' | pup 'td:nth-of-type(8) a[href] attr{href}'

4. Формируем команды вида (ниже), копипастим в консоль, ждем пока все загрузится:

curl -sSL https://msdl.microsoft.com/download/symbols/ntdll.dll/<BLOB>/ntdll.dll -o ntdll_<VERSION>.dll

5. Питоним скрипт для Binary Ninja по базовому экзамплу, получаем список офсетов:

import sys
import hashlib
from pathlib import Path
from multiprocessing import Pool, cpu_count, set_start_method

import binaryninja as bn

pe_dir = Path(sys.argv[1])
symbol_name = sys.argv[2]

def spawn(dll_path):
    bn.set_worker_thread_count(2)
    with bn.load(dll_path, update_analysis=True) as bv:
        symbol_obj = bv.get_symbol_by_raw_name(symbol_name)
        if symbol_obj:
            with open(dll_path, 'rb') as f:
                md5sum = hashlib.md5(f.read()).hexdigest()
            print(f'[*] {dll_path.name}:{md5sum} -> {hex(symbol_obj.address)}')

if __name__ == '__main__':
    set_start_method('spawn')
    processes = cpu_count()-1 if cpu_count() > 1 else 1
    pool = Pool(processes=processes)

    results = []
    for dll_path in pe_dir.glob('*.dll'):
        results.append(pool.apply_async(spawn, (dll_path,)))

    output = [result.get() for result in results]

Результат может быть полезен, например, для оценки примерных границ при поиске паттерна, когда заморачиваться с крафтом более аккуратного паттерна под все ОС лень, а так можно считерить и вывезти на грязном паттерне и более узких границах поиска:

PVOID getPattern(BYTE* pattern, DWORD patternSize, BYTE* startAddress) {
    BYTE* addr = startAddress;
    while (addr != (BYTE*)startAddress + 0xffff - patternSize)
    {
        if (addr[0] == pattern[0])
        {
            DWORD j = 1;
            while (j < patternSize && (pattern[j] == '?' || addr[j] == pattern[j])) j++;
            if (j == patternSize) return addr;
        }
        addr = addr + 1;
    }

    return NULL;
}
