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 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 […]
An important aspect of effective threat hunting is to understand what is normal in an environment. If a threat hunter is able to baseline the normal behaviour in a system then any abnormality is most likely due to an actor that has newly entered the environment. This actor could be a new software installation, new […]
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. […]
Most organizations face a barrage of attacks every day from threat actors around the globe. Among the various vectors, attackers have found relatively high degree of success by (spear) phishing employees of the organization. This allows attackers to bypass perimeter defences and gain a foothold in the internal network. SOC teams have multiple approaches to […]
