Win32/Kryptik.FONC 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 with CreateRemoteThread in a remote process;
  • Attempts to connect to a dead IP:Port (2 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.
  • 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.
  • HTTP traffic contains suspicious features which may be indicative of malware related traffic;
  • Performs some HTTP requests;
  • 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 for anti-virtualization via Device Information APIs;
  • Deletes its original binary from disk;
  • Sniffs keystrokes;
  • 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
  • Creates a copy of itself;
  • Creates a slightly modified copy of itself;
  • Ciphering the documents located on the target’s hard drive — so the victim can no more 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.
