Win32/Kryptik.GHTU 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.
  • 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.
  • A process attempted to delay the analysis task.;
  • Repeatedly searches for a not-found process, may want to run with startbrowser=1 option;
  • HTTP traffic contains suspicious features which may be indicative of malware related traffic;
  • Performs some HTTP requests;
  • Unconventionial language used in binary resources: Czech;
  • The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Detects Sandboxie through the presence of a library;
  • Deletes its original binary from disk;
  • Attempts to remove evidence of file being downloaded from the Internet;
  • Attempts to repeatedly call a single API many times in order to delay analysis time. This significantly complicates the work of the virus analyzer. Typical malware tactics!
  • Creates or sets a registry key to a long series of bytes, possibly to store a binary or malware config;
  • 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 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.
  • Checks the presence of disk drives in the registry, possibly for anti-virtualization;
  • Creates a copy of itself;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the documents found on the victim’s hard drive — so the sufferer can no longer make use of the information;
  • Preventing regular accessibility to the target’s workstation;
