Hey, It’s been a busy month for me and I was not able to save time to write the final part of the series on Malware Development. But I am receiving too many DMs on Twitter accounts lately to publish the final part. So here we are. If you are reading this blog, I am […]
Recap In the previous post, we wrote a simple CMD Reverse Shell over TCP. However, in a real-life scenario, things would be pretty different. In this post, we will be focusing on Evading Antivirus and covering the following topics: Creating a Simulated Environment using Windows Active Directory, DNS, Proxy and Firewall. Writing C/C++ code for […]
The Prologue This is my reposting of the blog series I wrote here at ScriptDotSh If you haven’t watched the videos yet, here are my links to both the antivirus evasions I performed: 1. Windows Cloud ML Defender Evasion 2. Kaspersky AV Evasion Besides the above two, I was also able to evade the Symantec […]
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 […]
