Trojan:Win32/Caynamer.W!MTB Summary

These adjustments 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);
• Attempts to connect to a dead IP:Port (3 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 named pipe was used for inter-process communication;
• A process created a hidden window;
• 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.

• Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.

• Preventing routine access 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.
