Trojan.Zygug.Gen.1 Summary

These modifications can be as follows:

  • Executable code extraction. Cybercriminals often use binary packers to hinder the malicious code from reverse-engineered by malware analysts. A packer is a tool that compresses, encrypts, and modifies a malicious file’s format. Sometimes packers can be used for legitimate ends, for example, to protect a program against cracking or copying.
  • Creates RWX memory. There is a security trick with memory regions that allows an attacker to fill a buffer with a shellcode and then execute it. Filling a buffer with shellcode isn’t a big deal, it’s just data. The problem arises when the attacker is able to control the instruction pointer (EIP), usually by corrupting a function’s stack frame using a stack-based buffer overflow, and then changing the flow of execution by assigning this pointer to the address of the shellcode.
  • A process attempted to delay the analysis task.;
  • Reads data out of its own binary image. The trick that allows the malware to read data out of your computer’s memory.

    Everything you run, type, or click on your computer goes through the memory. This includes passwords, bank account numbers, emails, and other confidential information. With this vulnerability, there is the potential for a malicious program to read that data.

  • A process created a hidden window;
  • Drops a binary and executes it. Trojan-Downloader installs itself to the system and waits until an Internet connection becomes available to connect to a remote server or website in order to download additional malware onto the infected computer.
  • The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Uses Windows utilities for basic functionality;
  • Queries information on disks, possibly for anti-virtualization. Since VMs share the same disk space so it is expected that they won’t be getting as much space as an application running on
    native hardware will have access to.
  • Creates a copy of itself;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Uses suspicious command line tools or Windows utilities;
  • Ciphering the files found on the sufferer’s hard disk — so the victim can no longer use the data;
  • Preventing normal accessibility to the sufferer’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.

Trojan.Zygug.Gen.1

  • By means of phishing e-mails;
  • As an effect of customer ending up on a resource that hosts a harmful software application;

As soon as the Trojan is efficiently infused, it will certainly either cipher the data on the victim’s computer or avoid the tool from working in a proper fashion – while additionally placing a ransom note that discusses the requirement for the sufferers to effect the repayment for the function of decrypting the records or bring back the data system back to the initial condition. In a lot of circumstances, the ransom note will come up when the client restarts the PC after the system has currently been harmed.

Trojan.Zygug.Gen.1 circulation channels.

In various corners of the world, Trojan.Zygug.Gen.1 expands by jumps and also bounds. However, the ransom money notes as well as techniques of obtaining the ransom money amount may vary depending on certain local (regional) setups. The ransom notes and tricks of extorting the ransom money amount might differ depending on specific local (local) settings.

Ransomware injection

    Faulty alerts about unlicensed software application.

    Faulty declarations regarding prohibited web content.

    In nations where software program piracy is much less prominent, this approach is not as efficient for the cyber frauds. Additionally, the Trojan.Zygug.Gen.1 popup alert may incorrectly assert to be deriving from a law enforcement institution and will certainly report having located youngster pornography or various other prohibited data on the tool.
