Backdoors (e.g., C99, R57, Webshells)
Hackers use Trojan horses, worms, implants and other methods to by pass security and identity authentication processes. These methods install Backdoors in the code which grant the hackers an easy access into the files with sensitive information and can be used to install more malicious codes and content into the compromised system.
The trojan is called Backdoor:PHP/WebShell.A. It grants unauthorized access to a remote computer which can then control the victim’s machine, compromising security of the user.
Early detection and quick removals are only ensured by signing up for a malware scanning service.
