Virus.Win32.PolyRansom.c Summary

These adjustments can be as adheres to:

• At least one process apparently crashed during execution;
• Executable code extraction. Cybercriminals often use binary packers to hinder the malicious code from reverse-engineered by malware analysts.

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.

• Creates a copy of itself;
• Ciphering the papers found on the sufferer’s hard disk drive — so the sufferer can no longer use the information;
