Backdoor:Win32/Bifrose.HM Summary

These alterations 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);
• Injection with CreateRemoteThread in a remote process;
• 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.
• 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.

  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.

• 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!
• 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 copy of itself;
• Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
• Ciphering the documents situated on the victim’s disk drive — so the sufferer can no longer make use of the information;
• Preventing normal accessibility 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.
