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.
  • Injection (inter-process);
  • Injection (Process Hollowing);
  • Injection with CreateRemoteThread in a remote process;
  • 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 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.

    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

  • Creates a copy of itself;
  • Creates known SpyNet mutexes and/or registry changes.;

  • Ciphering the documents situated on the victim’s hard disk drive — so the target can no longer make use of the data;
  • Preventing normal access 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.


One of the most common channels where Win32/Injector.ZUS are injected are:

  • By means of phishing e-mails;
  • As an effect of user winding up on a resource that organizes a harmful software;

As soon as the Trojan is effectively infused, it will certainly either cipher the data on the sufferer’s computer or protect against the tool from working in an appropriate fashion – while likewise putting a ransom money note that mentions the requirement for the victims to effect the repayment for the function of decrypting the files or recovering the file system back to the preliminary condition. In most circumstances, the ransom note will turn up when the customer restarts the COMPUTER after the system has actually currently been harmed.
