Backdoor.MSIL.NanoBot.benh Summary

These alterations can be as follows:

  • Injection (inter-process);
  • Injection (Process Hollowing);
  • 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 (1 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.
  • At least one IP Address, Domain, or File Name was found in a crypto call;
  • Expresses interest in specific running processes;
  • Reads data out of its own binary image. The trick that allows the malware to read data out of your computer’s memory.

  • Uses Windows utilities for basic functionality;
  • Executed a process and injected code into it, probably while unpacking;
  • Attempts to remove evidence of file being downloaded from the Internet;
  • 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

  • By ways of phishing e-mails;
  • As an effect of customer ending up on a resource that organizes a harmful software application;

As quickly as the Trojan is effectively injected, it will certainly either cipher the data on the sufferer’s PC or avoid the device from functioning in an appropriate way – while likewise placing a ransom money note that points out the requirement for the victims to impact the repayment for the function of decrypting the records or restoring the documents system back to the preliminary problem.
