Malware.AI.1877256242 Summary

These alterations can be as complies with:

  • Injection (inter-process);
  • Injection (Process Hollowing);
  • 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.
  • 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.
  • Attempts to connect to a dead IP:Port (20 unique times);
  • 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.

    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • Attempts to identify installed analysis tools by registry key;
  • Attempts to identify installed AV products by installation directory;
  • Checks the version of Bios, possibly for anti-virtualization;
  • Checks the presence of disk drives in the registry, possibly for anti-virtualization;
  • Detects VirtualBox through the presence of a file;
  • Detects VirtualBox through the presence of a registry key;
  • Detects VMware through the presence of a file;
  • Detects VMware through the presence of a registry key;
  • Detects Virtual PC through the presence of a file;
  • Detects Virtual PC through the presence of a registry key;
  • Attempts to modify browser security settings;
  • Creates a copy of itself;
  • Attempts to disable System Restore. System Restore function – allows you to revert the computer’s state (system files, applications, and system settings) to that of a previous point in time, which can be used to recover after a virus attack.
  • Generates some ICMP traffic;
  • 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 records found on the target’s disk drive — so the victim can no more use the data;
  • Preventing routine accessibility 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.


The most typical networks where Malware.AI.1877256242 Ransomware Trojans are injected are:

  • By methods of phishing e-mails;
  • As a repercussion of customer ending up on a resource that organizes a destructive software program;
