Hello, i am reading quite a lot from ARTeam, unfortunately i only got The Weakness of the Windows API Part 1 (from a 3 part series) in my archives, therefore i wanted to ask, where i could find the other two parts as this topic is very interesting for me. May it be that there is only one part available?

I am designing a delete function for a file manager i am coding however, i want to be able to delete a file even if you get that stupid windows "cant not delete due to blah" message. programs like unlocker. http://ccollomb.free.fr/unlocker/ search for all open handles for a given file and close them how is this acheived? i know after all handles are closed the obvious DeleteFileA is callled to delete the file. example, file1.txt has handle 1 and handle 2 open. search and find the handes CloseHandle(1) close handle(2) deleteFileA(file.txt); Delphi prefered but would settle with other langs and convert my self. TIA

PECompact problem
by grabb- 1 reply

I'm attempting to uncompress and PECompact 2.XX file, and having a frustrating time. I followed a number of the tutorials here, but I think I'm missing some important stuff regarding the import tables. Here's what I've done: - Loaded .exe in IDA and saw junk - Used a hex editor to view the file, saw the "PECompact" string and knew it needed unpacking - Loaded .exe into ollydbg (using some stealth plugins) and found the signature PECompact "JMP EAX" instruction - Modified the JMP EAX to JMP EIP so it goes into infinite loop at that point - Ran the "infinite loop" version of the .exe, then attached to the process using ollydbg. Program is decrypted in memory! - The…

Question about Windows memory architecture
by M4RCKUS- 2 replies
- 3k views
I'm very confused about one thing in Windows memory architecture. Thought someone here could help me out. The Virtual Address space (numbering) is unique to every process, right? I.E. application "A" can have some data structure at address 0x12345678, while another completely different application "B" can have completely different data structure at same address 0x12345678. Correct me if this is wrong. Now, assuming this, why is that virtual address space is split into partitions like from 0x00010000 to 0x7FFEFFFF for user mode applications and from 0x80000000 to 0xFFFFFFFF for kernel-mode apps. Why can't user-mode app take the "higher" part of address space if the space n…

PNG As Window/Region?
by Hyperlisk- 3 replies
- 3.4k views
Hi, I was wondering if anyone has any code they could share that demonstrates how to use a png image as a window. I have no idea where to start... I assume Either GDI+ or pnglib, but that's about it... But yeah... If anyone has anything they can share, I would be delighted to look at it. Hopefully in C/C++ or MASM, but I'm sure anything will be fine if I can adapt it. Thanks, Hyperlisk

Is there a plugin that allows to translate basic asm code from olly to c++/c# commands? I'm talking really the most basic commands like: SHL EAX,0A --> EAX = EAX << 0x0A OR EAX, ESI --> EAX = EAX | ESI AND EAX, ESI -> EAX = EAX & ESI XOR EAX,EBX --> EAX = EAX ^ EBX MOV EAX, EDX -> EAX = EDX etc... Please don't tell me to use inline asm because I'm programming in C#, which apparently does not support inline asm. And at the same time please dont tell me to use C++ as i already coded a lot of code for this keygen I'm working on and I'm not going to translate the code to c++.
