What is Nebula Exploit Kit? And how does it function?

Nebula Exploit Kit, as its name implies, is an exploit kit used by attackers to enable them in delivering their malicious payloads into a victim’s computer. This kind of malicious program can only find its way into your computer if your browsers, drivers, and programs like Java, Adobe Flash Player or Silverlight are not updated. In other words, exploit kits like the Nebula Exploit Kit take advantage of vulnerabilities in a system.
The Nebula Exploit Kit is a sophisticated malicious program that is relatively new and is being used to carry out destructive attacks on computer systems. Once it manages to infiltrate a system, it can install threats, collect information and carry out other harmful activities in an unprotected system. For instance, with the help of this exploit kit, cyber crooks can deliver a Trojan dropper or downloader which in turn, will also deliver other equally or more harmful threats. Nebula Exploit Kit ads were found in the dark web according to security experts. Not only that as its ads were also found lurking in forums and on shops on shady websites that are mostly out of reach to regular computer users.
Based on the reports, this exploit kit must be paid for first before other cyber crooks can use it. Its price depends on the amount of time they will use this malware – if crooks will be using it for 24 hours, they must pay $100, and a week will cost them $600 while a whole month will cost them $2000. Most of the reported attacks caused by Nebula are from Europe.
What makes this exploit kit sophisticated, aside from its functionality, is its legitimate-looking interface where crooks can connect and communicate with the developers of this exploit kit via instant messaging and email.
The Nebula Exploit kit can deliver a variety of malicious payloads in the targeted system including executable files, DLLs, Java scripts and Visual Basic files. According to researchers, this exploit kit contains the following features:

  • API rotator domains
  • Custom domains and servers
  • Automatic scanning and generating
  • The ability to delegate tasks by country and file
  • Generate a feed with statistics on eh ongoing malvertising campaigns

Moreover, this exploit kit is reported to be used in conjunction with two main types of threats such as crypto-currency mining malware and ransomware Trojans. As you probably know, a crypto-currency malware is designed to take over control of an infected system to use its resources in mining crypto-currency to generate money. Ransomware Trojans, on the other hand, are designed to encrypt important files in a system using a strong encryption algorithm to extort money from its victims.
