Trojan.Pseudo Summary

These alterations 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.
  • 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.
  • 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;
  • Attempts to remove evidence of file being downloaded from the Internet;
  • Attempts to delete volume shadow copies;
  • Deletes its original binary from disk;
  • Exhibits behavior characteristic of Alphacrypt/Teslacrypt ransomware;
  • 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
  • Exhibits possible ransomware file modification behavior;
  • Writes a potential ransom message to disk;
  • Creates a hidden or system file. The malware adds the hidden attribute to every file and folder on your system, so it appears as if everything has been deleted from your hard drive.
  • Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
  • 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 records found on the sufferer’s disk drive — so the target can no longer use the information;
  • Preventing routine accessibility to the target’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.Pseudo

One of the most common channels through which Trojan.Pseudo Ransomware Trojans are injected are:

  • By ways of phishing e-mails;
  • As an effect of user ending up on a source that hosts a destructive software;

As quickly as the Trojan is efficiently injected, it will either cipher the information on the target’s PC or prevent the tool from functioning in an appropriate way – while also positioning a ransom note that mentions the need for the sufferers to effect the settlement for the purpose of decrypting the documents or restoring the data system back to the initial problem. In the majority of circumstances, the ransom money note will show up when the customer reboots the PC after the system has already been damaged.

Trojan.Pseudo distribution networks.

In different edges of the globe, Trojan.Pseudo expands by jumps and bounds. Nonetheless, the ransom money notes as well as techniques of extorting the ransom amount might differ depending upon certain regional (regional) setups. The ransom money notes and techniques of obtaining the ransom quantity may vary depending on certain regional (local) setups.

Ransomware injection

For example:

    Faulty informs concerning unlicensed software.

    In particular areas, the Trojans usually wrongfully report having actually detected some unlicensed applications allowed on the target’s tool. The alert after that demands the individual to pay the ransom.

    Faulty declarations regarding unlawful content.

    In countries where software application piracy is much less prominent, this technique is not as reliable for the cyber fraudulences. Alternatively, the Trojan.Pseudo popup alert may falsely assert to be deriving from a police organization and also will report having located child pornography or other prohibited data on the gadget.

    Trojan.Pseudo popup alert may wrongly assert to be obtaining from a law enforcement organization and will report having located child pornography or other illegal information on the device. The alert will likewise contain a need for the customer to pay the ransom.
