VirTool:Win32/CeeInject.AJM!bit 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 (inter-process);
  • 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;
  • Repeatedly searches for a not-found process, may want to run with startbrowser=1 option;
  • 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.
  • Unconventionial language used in binary resources: Slovenian;
  • 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;
  • Detects Sandboxie through the presence of a library;
  • Detects the presence of Wine emulator via function name;
  • Creates or sets a registry key to a long series of bytes, possibly to store a binary or malware config;
  • 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
  • Attempts to identify installed analysis tools by a known file location;
  • Checks for the presence of known devices from debuggers and forensic tools;
  • Detects the presence of Wine emulator via registry key;
  • Detects Sandboxie using a known mutex;
  • Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
  • Creates a copy of itself;
  • Checks for a known DeepFreeze Frozen State Mutex;
  • 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 found on the victim’s disk drive — so the target can no longer use the data;
  • Preventing routine accessibility to the sufferer’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 a repercussion of customer ending up on a resource that hosts a harmful software;

As quickly as the Trojan is efficiently infused, it will certainly either cipher the data on the victim’s computer or avoid the tool from functioning in a proper way – while likewise positioning a ransom note that discusses the demand for the sufferers to impact the settlement for the purpose of decrypting the documents or recovering the file system back to the initial condition. In most circumstances, the ransom note will show up when the client reboots the COMPUTER after the system has already been harmed.

In different corners of the globe, VirTool:Win32/CeeInject.AJM!bit grows by leaps as well as bounds. Nevertheless, the ransom money notes and also techniques of obtaining the ransom money amount may differ relying on particular neighborhood (local) setups. The ransom money notes and also tricks of obtaining the ransom quantity might vary depending on certain regional (local) settings.
