What is PUA:Win32/Creprote infection?

In this post you will certainly find regarding the interpretation of PUA:Win32/Creprote as well as its adverse impact on your computer. Such ransomware are a type of malware that is elaborated by online fraudulences to require paying the ransom money by a target.

Most of the instances, PUA:Win32/Creprote ransomware will certainly advise its victims to initiate funds transfer for the function of reducing the effects of the modifications that the Trojan infection has actually introduced to the sufferer’s tool.

PUA:Win32/Creprote 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.
• 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.
• Starts servers listening on 0.0.0.0:43591, 0.0.0.0:43594, 0.0.0.0:43592, 0.0.0.0:43597, 0.0.0.0:43595;
• 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: Portuguese (Brazilian);
• 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.
• 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
• Collects information about installed applications;
• Creates a hidden or system file. The malware adds the hidden attribute to every file and folder on your system, so it appears as if everything has been deleted from your hard drive.
• Attempts to identify installed AV products by installation directory;
• Checks for the presence of known devices from debuggers and forensic tools;
• Checks the presence of disk drives in the registry, possibly for anti-virtualization;
• Detects VirtualBox through the presence of a registry key;
• Creates a copy of itself;
• Attempts to interact with an Alternate Data Stream (ADS);
• 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 records found on the target’s hard disk — so the sufferer can no longer make use of the data;
• Preventing regular accessibility to the target’s workstation;
