Trojan:Win32/Ranumbot.RW!MTB 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);
  • Compression (or decompression);
  • 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.
  • Detected script timer window indicative of sleep style evasion;
  • At least one IP Address, Domain, or File Name was found in a crypto call;
  • A named pipe was used for inter-process communication;
  • Expresses interest in specific running processes;
  • 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.

  • Unconventionial language used in binary resources: Russian;
  • A scripting utility was executed;
  • Uses Windows utilities for basic functionality;
  • Forces a created process to be the child of an unrelated process;
  • Executed a process and injected code into it, probably while unpacking;

    native hardware will have access to.
  • Checks for the presence of known windows from debuggers and forensic tools;
  • A process attempted to delay the analysis task by a long amount of time.;
  • 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;
  • Network activity contains more than one unique useragent.;
  • Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
  • 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 files found on the sufferer’s disk drive — so the sufferer can no more use the information;
  • Preventing regular access to the sufferer’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.

In a lot of circumstances, the ransom money note will certainly turn up when the customer restarts the PC after the system has currently been damaged.
