INTRODUCTION TO MALWARE DEVELOPMENT

 

    


  Hello, today we will discuss the development of malware. Please note that this article is solely intended for educational purposes and that I take no responsibility for any misbehavior you may commit.

Thus, let's begin by discussing what malware is. According to the Wiki, malware is any software that is specifically made with the intent to harm a computer, server, client, or computer network; leak confidential data; obtain unauthorized access to data or systems; prevent users from accessing data; or inadvertently compromise user privacy and security on their computers. Malware, such as computer viruses, worms, Trojan horses, ransomware, spyware, adware, rogue software, wipers, and keyloggers, is often categorized by researchers into one or more subtypes.

Now, in malware development, we will try to develop a stealer. So, what is a stealer? A stealer or infostealer, is a program that secretly collects data and sends it to their server. It can be a Windows program, an Android program, or an iOS program; it can be an exe file or an apk file for Android. It depends on the developer of the stealer on how he will craft the malware.


Some capabilities of an infostealer

1. Retrieves your location

2. Retrieves your images

3. Retrieves your browser credentials

4. Retrieves your Wi-Fi credentials

5. Retrieves your Files

6. Act as a Legit Program/Software

7. Undetectable by Antiviruses, really even endpoints can’t detect these malwares.

In malware development, it is most effective to use lower-level programming languages such as C and C++ that really interact with the kernel of the operating system; thus, there are many programming languages nowadays like Python, C#, Java, JavaScript, and the like. It still depends on the developer as to whether he or she is proficient in developing the malware. Malware developers are getting smarter on developing this kind of program.
