This blog post proposes an approach to crack Pseudo-Random Number Generators (PRNGs) using machine learning. By cracking here, we mean that we can predict the sequence of the random numbers using previously generated numbers without the knowledge of the seed.…

At the beginning of October, Apache released version 2.4.49 to fix a Path Traversal and Remote Code Execution vulnerability and then 2.4.50 to address the fact that the fix was incomplete. We’ve built a mission to demonstrate the risks in a real-life environment.…

Microsoft in an attempt to provide more flexibility to domain users enabled owner of resources to configure which accounts are trusted and allowed to delegate to them. This is achieved by modificat…

During a recent malware incident response case, we encountered an interesting piece of ransomware that goes by the name of BlackByte.

part 1 of this post, we showed how to train a Neural Network to generate the exact sequence of a relatively simple pseudo-random number generator (PRNG), namely xorshift128. In that PRNG, each number is totally dependent on the last four generated numbers…
