How Cyber Attacks Work
A cyberattack is a malicious and deliberate attempt by
an individual or organization to breach the information system of another
individual or organization. Usually, the attacker seeks some type of benefit
from disrupting the victim’s network.
How often do cyber attacks occur?
Cyberattacks hit businesses every day. Former Cisco CEO John Chambers once
said, “There are two types of companies: those that have been hacked, and those
who don’t yet know they have been hacked.” According to the Cisco Annual
Cybersecurity Report, the total volume of events has increased
almost fourfold between January 2016 and October 2017.
Why do people launch
cyber attacks?
Cybercrime has increased every year as people try to
benefit from vulnerable business systems. Often, attackers are looking for
ransom: 53 percent of cyber attacks resulted in damages of $500,000 or more.
Cyberthreats can also be launched with ulterior motives.
Some attackers look to obliterate systems and data as a form of “hacktivism.”
What is a botnet?
A
botnet is a network of devices that has been infected with malicious software,
such as a virus.
Attackers can control a botnet as a group without the owner’s knowledge with
the goal of increasing the magnitude of their attacks. Often, a botnet is used
to overwhelm systems in a distributed-denial-of-service
attack (DDoS) attack.
