Most of the situations, Backdoor:MSIL/Noancooe.C ransomware will advise its victims to launch funds transfer for the function of neutralizing the amendments that the Trojan infection has actually introduced to the victim’s tool.

Backdoor:MSIL/Noancooe.C 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);
  • 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.
  • A process attempted to delay the analysis task.;
  • At least one IP Address, Domain, or File Name was found in a crypto call;
  • 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;
  • Attempts to remove evidence of file being downloaded from the Internet;
  • Detects Sandboxie through the presence of a library;
  • Executed a process and injected code into it, probably while unpacking;
  • 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
  • Exhibits behavior characteristic of Nanocore RAT;
  • 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.
  • Creates a 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 documents located on the victim’s hard disk — so the sufferer can no longer make use of the data;
  • Preventing normal accessibility 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.

  • By methods of phishing emails;
  • As an effect of individual ending up on a source that organizes a malicious software;

As quickly as the Trojan is effectively injected, it will certainly either cipher the information on the sufferer’s computer or avoid the device from operating in a proper fashion – while additionally positioning a ransom note that states the requirement for the targets to effect the payment for the purpose of decrypting the papers or bring back the data system back to the preliminary condition. In many instances, the ransom note will come up when the client restarts the COMPUTER after the system has currently been harmed.
