Define: Attack Vector

A cyber attack vector is a method of gaining unauthorized access to a private IT network. Cybercriminals exploit attack vectors to launch cyberattacks and inject malicious payloads.

Attack vectors can be digital, such as a software vulnerability, or analog, such as an employee that can be influenced to divulge private access credentials.

Third-party vendors are critical attack vectors since they have access to the private data of each business they’ve partnered with. Because of this, when a vendor is compromised, all of its clients often become compromised too.

This type of cyberattack is known as a supply chain attack and because of its efficiency, it’s quickly becoming the favourite choice amongst cybercriminals.
