Dynamic Binary Instrumentation (DBI) is a method of analyzing the behavior of a binary application at runtime through the injection of instrumentation code - Uninformed 2007

Finding bugs is hard, reverse engineering is hard. Constraint solvers are the heart of many program analysis techniques, and can aid Fuzzing, and software verification.

Well, its 2017 and I’m writing about DLL injection. It could be worse. DLL injection is a technique used by legitimate software to add/extend functionality to other programs, debugging, or reverse engineering. It is also commonly used by malware in a multitude of ways. This means that from a security perspective, it’s imperative to know how DLL injection works.

I was a bit bored of switching between metasm_shell and nasm_shell every time I had to play with assembly instructions and opcodes during exploit development or reversing code.

During Red Team engagements it is common to track/hunt specific users. Assuming we already have access to a desktop as a normal user (no matter how, always “assume compromise”) in a Windows Domain and we want to spread laterally.

After my previous post here, I got a message from an anonymous source asking me if I would like to have a look at another piece of malware written in managed code (that was also on the news recently). More precisely at the ‘Orcus RAT’.

I had never heard of ‘HawkEye Keylogger’ until I’ve read the following blog post from Trustwave. I’ve found the amount of features quite interesting and I was curious to have a closer look at the source code.
