There are several weak loop holes from where intruders can attack your system but now let’s have a look on causes of cybercrime.

  • Unpatched vulnerabilities
  • Complex and unprofessional coding
  • Human error
  • Negligence
  • Loss of evidence
  • Data carrying hardware like USB or Flash Drive
