PWS:Win32/Zbot!ml Summary

These alterations 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.
  • 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;
  • Attempts to connect to a dead IP:Port (54 unique times);
  • Reads data out of its own binary image. The trick that allows the malware to read data out of your computer’s memory.

  • Creates or sets a registry key to a long series of bytes, possibly to store a binary or malware config;
  • Creates a registry key or value with NUL characters to avoid detection with regedit;
  • 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
  • Stores JavaScript or a script command in the registry, likely for persistence or configuration;
  • Attempts to identify installed analysis tools by registry key;
  • Attempts to identify installed AV products by installation directory;
  • Checks the version of Bios, possibly for anti-virtualization;
  • Checks the presence of disk drives in the registry, possibly for anti-virtualization;
  • Detects VirtualBox through the presence of a file;
  • Detects VirtualBox through the presence of a registry key;
  • Detects VMware through the presence of a file;
  • Detects VMware through the presence of a registry key;
  • Detects Virtual PC through the presence of a file;
  • Attempts to modify browser security settings;
  • 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.
  • Ciphering the papers situated on the victim’s disk drive — so the target can no longer utilize the data;
  • Preventing regular accessibility to the target’s workstation;
