Один из подписчиков поделился новым курсом от Sektor7, и был не против отдать его в массы. Это уже третья часть про разработку малвари: Malware Development Advanced Vol.1

Остальные курсы Sector7 тоже есть на канале:
1. RTO: Malware Development Essentials
2. RTO: Windows Persistence
3. RTO: Privilege Escalation in Windows
4. RTO: Malware Development Intermediate
5. RTO: Evasion Windows

If you are facing an EDR with PEB protection/obf which makes Ldr inaccessible & want to inject shellcode, just pass the VA of LoadLibrary (which is consistent across processes) to the shellcode via egg-hunting from your injector, enabling lib resolution without touching the PEB.

TrollUAC

• .NET library that serves as a UAC bypass for x64
• Any* process with the uiAccess flag enabled can "Send Keystrokes" to high integrity processes even from medium integrity
• We steal the token of On Screen Keyboard (uiAccess enabled) to spawn a new process that does GUI automation
• The GUI automation simply sends keystrokes to taskmgr (auto elevate) to spawn our new desired process in high integrity
• *Refer to tiraniddo's article for requirements, although they can easily be conjured up
