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;
}

There are some interesting detections for U2U/UnPAC the hash in certipy/rubues/mimiktaz/impacket based on TGS ticket options. Did some tinkering and by removing a few flags you can shake detection while still recovering the NT hash from a TGT.
