In the majority of cases, you will not detect any suspicious activity on your PC. Program:Win32/Wacapew.C!ml is a typical example of print spoofer. These applications are used by cybercriminals to escalate the permissions of certain users on the local computer or in the computer network. After that action crooks can manage the whole network like they have the admin’s permissions.

Program:Win32/Wacapew.C!ml Summary

These alterations can be as follows:

  • 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.
  • 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.
  • Network activity detected but not expressed in API logs. Microsoft built an API solution right into its Windows operating system it reveals network activity for all apps and programs that ran on the computer in the past 30-days. This malware hides network activity.
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Exploiting the Windows vulnerabilities. Print spoofers, like Wacapew.C!ml, change several system configurations to give the user (or the PC) they launched on administrator rights.
