Trojan.LVBP 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.
  • Injection (inter-process);
  • Injection (Process Hollowing);
  • Injection with CreateRemoteThread in a remote process;
  • Attempts to connect to a dead IP:Port (1 unique times);
  • 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.
  • Expresses interest in specific running processes;
  • 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.

  • HTTP traffic contains suspicious features which may be indicative of malware related traffic;
  • Performs some HTTP requests;
  • Exhibits behavior characteristic of Andromeda/Gamarue malware;
  • Detects Sandboxie through the presence of a library;
  • Executed a process and injected code into it, probably while unpacking;
  • Attempts to stop active services;
  • Tries to unhook or modify Windows functions monitored by Cuckoo;
  • Mimics the file times of a Windows system file;
  • 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
  • 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.
  • Creates a copy of itself;
  • Attempts to disable UAC.

    User Account Control or just UAC is a part of the Windows security system which prevents apps from making unwanted changes on PC.

    UAC includes several technologies 1:

    • File and egistry Virtualization;
    • Same-desktop Elevation;
    • Filtered Token;
    • User Interface Privilege Isolation;
    • Protected Mode Internet Explorer;
    • Installer Detection;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Attempts to modify Explorer settings to prevent hidden files from being displayed;
  • Attempts to modify user notification settings;
  • Ciphering the papers found on the victim’s disk drive — so the sufferer can no more use the information;
  • Preventing routine accessibility 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.
