In this short article you will certainly find regarding the definition of Trojan.Win32.Zenpak.ahnx as well as its unfavorable impact on your computer. Such ransomware are a kind of malware that is specified by online fraudulences to require paying the ransom money by a victim.

Trojan.Win32.Zenpak.ahnx Summary

These adjustments can be as adheres to:

  • 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.
  • Injection (inter-process);
  • Injection (Process Hollowing);
  • Presents an Authenticode digital signature;
  • 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.
  • Possible date expiration check, exits too soon after checking local time;
  • Mimics the system’s user agent string for its own requests;
  • A process attempted to delay the analysis task.;
  • A named pipe was used for inter-process communication;
  • Expresses interest in specific running processes;
  • Repeatedly searches for a not-found process, may want to run with startbrowser=1 option;
  • 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.
  • Performs some HTTP requests;
  • Unconventionial binary language: Chinese (Simplified);
  • Unconventionial language used in binary resources: Chinese (Simplified);
  • Uses Windows utilities for basic functionality;
  • Executed a process and injected code into it, probably while unpacking;
  • A system process is generating network traffic likely as a result of process injection;
  • Installs itself for autorun at Windows startup.

    There is simple tactic using the Windows startup folder located at:
    C:\Users\[user-name]\AppData\Roaming\Microsoft\Windows\StartMenu\Programs\Startup Shortcut links (.lnk extension) placed in this folder will cause Windows to launch the application each time [user-name] logs into Windows.

    The registry run keys perform the same action, and can be located in different locations:

    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • Checks the version of Bios, possibly for anti-virtualization;
  • Checks the CPU name from registry, possibly for anti-virtualization;
  • Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
  • Creates a copy of itself;
  • Collects information to fingerprint the system. There are behavioral human characteristics that can be used to digitally identify a person to grant access to systems, devices, or data. Unlike passwords and verification codes, fingerprints are fundamental parts of user’s identities. Among the threats blocked on biometric data processing and storage systems is spyware, the malware used in phishing attacks (mostly spyware downloaders and droppers), ransomware, and Banking Trojans as posing the greatest danger.
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the files found on the target’s hard drive — so the victim can no more use the information;
  • Preventing regular access to the victim’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.
