This paper discusses a challenging CTF-like task. Your goal is to get remote code execution on a SOAP server. All exploitation primitives are involved with the heap in one way or another; so, you’ll learn a lot about functions interacting with it. Also, you’ll reverse a Linux binary using a dynamic instrumentation framework.

The magic and charm of dynamic routing protocols can be deceptive: admins trust them implicitly and often forget to properly configure security systems embedded in these protocols. In this article, I will explain what nightmares can occur if the network admin doesn’t take a good care of the security of OSPF and EIGRP routing domains.

Virtually all modern bank cards are equipped with a special chip that stores data required to make payments. This article discusses fraud techniques used to compromise such cards and methods used by banks to protect cardholders against attackers.

Up until recently, just a few people (aside from specialists) were aware of the Log4j logging utility. However, a vulnerability found in this library attracted to it a great attention from researches nowadays. Let’s take a closer look at the origin and operation mechanism of this bug and examine the available exploits to it.

WinAFL is a fork of the renowned AFL fuzzer developed to fuzz closed-source programs on Windows systems. All aspects of WinAFL operation are described in the official documentation, but its practical use – from downloading to successful fuzzing and first crashes – is not that simple.

When you investigate an incident, it’s critical to establish the exact time of the attack and method used to compromise the system. This enables you to track the entire chain of operations performed by the malefactor. Today, I will show how to do this using the Timesketch tool.

Is the phrase “This script contains malicious content and has been blocked by your antivirus software” familiar to you? It’s generated by Antimalware Scan Interface (AMSI), a protection mechanism embedded in Windows 10 that blocks the execution of malicious scripts. But can AMSI be bypassed? Sure, and today I will show how to do this.
