Win32/Kryptik.EYFV 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.
• Attempts to connect to a dead IP:Port (1 unique times);
• Enumerates user accounts on the system;
• 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 attempted to delay the analysis task.;
• 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.

• 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;
• Creates or sets a registry key to a long series of bytes, possibly to store a binary or malware config;
• 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.
• Attempts to identify installed AV products by installation directory;
• 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 files situated on the victim’s disk drive — so the sufferer can no longer make use of the data;
