Ransom.141 Summary

These modifications can be as adheres to:

• 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.
• Attempts to connect to a dead IP:Port (4 unique times);
• 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.;
• A process created a hidden window;
• Creates an excessive number of UDP connection attempts to external IP addresses;
• Performs some HTTP requests;
• 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 modify desktop wallpaper;
• Attempts to execute a binary from a dead or sinkholed URL;
• Writes a potential ransom message to disk;
• EternalBlue behavior. Allows cyber threat actors to remotely execute arbitrary code and gain access to a network by sending specially crafted packets.

  This is has made EternalBlue trick popular with various malware, such as Trickbot, a modular banking trojan, as well as CoinMiner and WannaMine, crypto miners that use the EternalBlue exploit in order to gain access to computing power to mine cryptocurrencies.

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 documents found on the target’s hard drive — so the target can no more use the data;
• Preventing routine accessibility to the victim’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.

One of the most common channels through which Ransom.141 Ransomware Trojans are injected 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 a repercussion of user winding up on a source that hosts a malicious software program;

As quickly as the Trojan is effectively injected, it will either cipher the information on the victim’s PC or stop the device from operating in an appropriate manner – while likewise putting a ransom money note that discusses the need for the sufferers to effect the repayment for the purpose of decrypting the papers or bring back the file system back to the initial problem.
