VirTool:Win32/VBInject.ACV!bit Summary
These modifications can be as complies with:
- 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);
- Presents an Authenticode digital signature;
- 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.
- 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.
- The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
- Queries information on disks, possibly for anti-virtualization. Since VMs share the same disk space so it is expected that they won’t be getting as much space as an application running on
native hardware will have access to. - Attempts to remove evidence of file being downloaded from the Internet;
- Executed a process and injected code into it, probably while unpacking;
- Creates or sets a registry key to a long series of bytes, possibly to store a binary or malware config;
- Steals private information from local Internet browsers;
- 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
- Spoofs its process name and/or associated pathname to appear as a legitimate process;
- Harvests credentials from local FTP client softwares;
- Harvests information related to installed instant messenger clients;
- Harvests information related to installed mail clients;
- 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.
- Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
- Ciphering the papers found on the target’s hard disk drive — so the victim can no more use the information;
- Preventing routine access 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.
