The world’s most popular torrent client, uTorrent, contained a security vulnerability — later to be called CVE-2020-8437— that could be exploited by a remote attacker to crash and corrupt any uTorrent instance connected to the internet.

Imagine if your first reverse engineering exercise was to reconstruct an encrypted IAT – if you don’t fully know what that means, that’s the point: beginner reverse engineering exercises should be clear (and fun)!

When researching or just tinkering with Windows and Microsoft executables, having the source code is a great advantage. This short article is a collection of links to Windows and Microsoft code, and a story about it.

During April I challenged myself to tweet 1 reverse engineering tip every day. For your viewing pleasure, here I aggregated all 30 tips.

When reversing or fuzzing an executable, being able to run an arbitrary function with controlled data is extremely helpful. A dll (Dynamic Linked Library) with our target function would allow us to conveniently review and test the function as we wish. The only problem is that usually the function we want to examine resides in an exe, not a dll. Converting an exe to a dll is a doable. After all, both an exe and a dll share the same PE file format.
