Trojan.Agent.MTA 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.
  • Mimics the system’s user agent string for its own requests;
  • Possible date expiration check, exits too soon after checking local time;
  • A process attempted to delay the analysis task.;
  • At least one IP Address, Domain, or File Name was found in a crypto call;

    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.
  • Uses Windows utilities for basic functionality;
  • Code injection with CreateRemoteThread in a remote process;
  • Deletes its original binary from disk;
  • Executed a process and injected code into it, probably while unpacking;
  • Tries to unhook or modify Windows functions monitored by Cuckoo;
  • 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_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 Zeus (Banking Trojan) mutexes;
  • Attempts to modify browser security settings;
  • Harvests credentials from local FTP client softwares;
  • Attempts to interact with an Alternate Data Stream (ADS);

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 found on the sufferer’s hard drive — so the target can no longer use 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.

Trojan.Agent.MTA

One of the most normal networks through which Trojan.Agent.MTA Ransomware Trojans are infused are:

  • By methods of phishing e-mails. Email phishing is a cyber attack that uses disguised email as a goal is to trick the recipient into believing that the message is something they want or need — a request from their bank, for instance, or a note from someone in their company — and to click a link for download a malware.
  • As an effect of user ending up on a resource that organizes a destructive software program;

As quickly as the Trojan is efficiently infused, it will certainly either cipher the data on the target’s computer or protect against the gadget from operating in a proper way – while also positioning a ransom money note that states the requirement for the sufferers to impact the settlement for the function of decrypting the papers or restoring the data system back to the first condition. In a lot of circumstances, the ransom note will certainly show up when the customer reboots the COMPUTER after the system has actually already been damaged.
