Win32:Zbot-PZJ [Trj] Summary

These modifications 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 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.
• Mimics the system’s user agent string for its own requests;
• A process attempted to delay the analysis task.;
• At least one IP Address, Domain, or File Name was found in a crypto call;
• Starts servers listening on 0.0.0.0:16457, :0, 127.0.0.1:10173;
• 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.

• 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;
• Code injection with CreateRemoteThread in a remote process;
• Tries to unhook or modify Windows functions monitored by Cuckoo;
• Steals private information from local Internet browsers;
• Behavior consistent with a dropper attempting to download the next stage.;
• 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 Zeus (Banking Trojan) mutexes;
• Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
• Attempts to modify browser security settings;
• Harvests credentials from local FTP client softwares;
• Attempts to interact with an Alternate Data Stream (ADS);
• Creates a slightly modified copy of itself;
• 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.
• Ciphering the records located on the target’s hard disk — so the victim can no longer utilize the data;
• Preventing routine accessibility to the victim’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.

As quickly as the Trojan is successfully injected, it will either cipher the data on the victim’s PC or prevent the device from operating in an appropriate manner – while also putting a ransom money note that mentions the requirement for the victims to impact the settlement for the function of decrypting the papers or bring back the file system back to the initial condition. In the majority of instances, the ransom money note will show up when the customer restarts the PC after the system has actually already been harmed.
