What is a backdoor?

A backdoor refers to any method by which unauthorized or even authorized users can get around standard security measures and gain high-level user access on a computer system, network, or software application.

Backdoors can also be installed by software or hardware makers as a deliberate means of gaining access to their technology after the fact. Backdoors of the non-criminal variety help customers who are hopelessly locked out of their devices or troubleshoot and resolve software issues.

A malicious user can install a backdoor by taking advantage of vulnerable systems on a web application, and once installed, detection is difficult as files tend to obfuscate.

Webserver backdoors are used for several malicious activities, including:

  • Data theft
  • Website defacing
  • Server hijacking
  • The launching of a distributed denial of service (DDoS) attacks
  • Infecting website visitors (watering hole attacks)
  • Advanced persistent threat (APT) assaults
