In the majority of the instances, Win32/Kryptik.HLCH infection will certainly instruct its targets to initiate funds move for the objective of reducing the effects of the changes that the Trojan infection has introduced to the sufferer’s tool.

Win32/Kryptik.HLCH Summary

These adjustments 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);
  • 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.
  • Possible date expiration check, exits too soon after checking local time;
  • 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.
  • 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.
  • Executed a process and injected code into it, probably while unpacking;
  • 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!
  • Network activity contains more than one unique useragent.;
  • 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
  • Writes a potential ransom message to disk;
  • Likely virus infection of existing system binary;
  • Creates a copy of itself;
  • The sample wrote data to the system hosts file.;
  • Collects information to fingerprint the system. There are behavioral human characteristics that can be used to digitally identify a person to grant access to systems, devices, or data. Unlike passwords and verification codes, fingerprints are fundamental parts of user’s identities. Among the threats blocked on biometric data processing and storage systems is spyware, the malware used in phishing attacks (mostly spyware downloaders and droppers), ransomware, and Banking Trojans as posing the greatest danger.
  • 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 found on the sufferer’s hard drive — so the target can no longer use the information;
  • Preventing normal access to the sufferer’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.
