Trojan:MSIL/Bokytuda.B!bit 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.
• 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.

• 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.
• 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;
• Installs itself for autorun at Windows startup.

  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.
• Network activity detected but not expressed in API logs. Microsoft built an API solution right into its Windows operating system it reveals network activity for all apps and programs that ran on the computer in the past 30-days. This malware hides network activity.
• Checks the presence of disk drives in the registry, possibly for anti-virtualization;
• Creates a copy of itself;
• Uses suspicious command line tools or Windows utilities;
• Ciphering the records found on the target’s hard drive — so the sufferer can no more make use of the data;
• Preventing routine access 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.
