Cyber Attacks



There are many types of malware with each having its specific goal and technique.

  • Viruses – Viruses are aimed to steal, modify, or corrupt data from targeted computers. A virus can replicate and spread itself from one computer to another by attaching itself to another file.
  • Worms – Worms are aimed to seek out and exploit weaknesses in operating systems to allow remote control of the infected computers. A worm can replicate and spread itself from one computer to another without the need of attaching itself to another file.
  • Spyware – Spyware, or also known as adware, is aimed to steal data through remote control of the infected computers. Spyware infects computers through attachments, links, or downloadable software.
  • Trojans – Trojan is aimed to steal or damage data through the creation of another door on the infected computers.


Attack Vectors

Besides the above attacks, there are also some attack vectors that allow cyber criminals to infect computers to harvest stolen data.

  • Phishing – Aimed to collect users’ data by masquerading as a legitimate entity.
  • Pharming – Aimed to redirect a web’s traffic to a fake web where users’ data are compromised.
  • Drive-by – Aimed to attack against specific weakness in a system.
  • MITM (Man in the Middle) Attack – Aimed to manipulate impersonate each endpoint and manipulate them.
