Trojan:Win32/DorkBot.DU 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.
• At least one process apparently crashed during execution;
• Injection (inter-process);
• Injection (Process Hollowing);
• Injection with CreateRemoteThread in a remote process;
• Attempts to connect to a dead IP:Port (2 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.
• At least one IP Address, Domain, or File Name was found in a crypto call;
• Performs some HTTP requests;
• Unconventionial language used in binary resources: Spanish (Puerto Rico);
• The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
• Executed a process and injected code into it, probably while unpacking;
• Code injection with CreateRemoteThread in a remote process;
• Crashed cuckoomon during analysis. Report this error to the Github repo.;
• A process attempted to delay the analysis task by a long amount of time.;
