As you might already be aware that ARM powers a variety of low-powered devices around us, including but not limited to, phones, routers, IoT devices, etc. Therefore, it is only logical to dig into this architecture and understand how it differs from x86 and x64 architectures. For this blog post, we will focus on 64bit […]
Prologue In the previous blog here, we reverse engineered a simple binary containing plaintext password in Linux with the help of GNU Debugger (GDB). In this blog however, we will be using the same source code of the binary but compile and debug it in Windows. Reverse engineering tools in Windows are highly different from […]
Prologue The main focus of this blog is to give a push start to the beginners to get in the field of reverse engineering. Since this is the age of x64, I have skipped x86 architecture and will solely be focusing on x64 assembly. However, all the examples that will be written in C++ can […]
Welcome to the part 4 of malware development .In the previous parts 1, 2-1, 2-2 and 3, we created a binary which can listen to the commands from our botnet server. We also wrote the C2 server in python3 which can handle multiple connections via multithreading and send commands to all of them. In this […]
In the previous parts 1, 2-1 and 2-2 of this series we created a binary that can connect to, and parse commands sent via netcat listener. However, netcat is not an ideal choice for a Botnet Server, and in this post, we will be writing a full-fledged python3 Botnet Server, sending commands to our Bot […]
In the previous parts of this blog series, I introduced the concept of writing a full-undetectable malware and about writing a client-side socket using Windows API. In this blog, we are going to parse the reply received from the netcat server and prompt a reply as to whether the command was parsed or not. […]
Welcome to the second part of the malware development blog series. Here’s the link to Part 1. Given the length of Part 2, I have split this 2nd part of the blog series into two itself. So, this is what we will cover in part 2: Hide the console Window from user [Part 2-1] Write […]
If you are in cybersecurity, especially Red Teaming, writing a full-undetectable (FUD) malware is a great skill to have. Folks tend to use Metasploit combined with Veil-Evasion or PE injectors like LordPE or Shelter, to generate a binary which can bypass the antivirus. Sometimes this works and sometimes it does not. The worst thing that […]
[[Post was originally posted on 23rd May, 2017 at invadersam.com]] Microsoft Office Word / Wordpad remote code execution vulnerability allows a remote attacker to execute arbitrary code on the system. An attacker can send specially crafted files which can cause the MS Word / Wordpad to download a remote shell and the attacker can gain […]
Before we start to configure our decoys and put it in our production environment, let’s take a look at what exactly it is and how it differs from the usual honeypot. Honeypots are vulnerable systems configured to lure the attacker who is present in an organization. This attacker need not be from outside the environment. […]
