1. On unsecure public Wi-Fi, attackers can insert themselves between a visitor’s device and the network. Without knowing, the visitor passes all information through the attacker.

WHAT IS A CYBERATTACK?
 A cyberattack is a malicious and deliberate attempt by an

WHY DO PEOPLE LAUNCH CYBER ATTACKS?
 Cybercrime has increased every year as people try to benefit
from weak business systems. Often, attackers are looking for
ransom: 53 percent of cyber attacks resulted in damages of
$500,000 or more.
 Some attackers look to obliterate (destroy) systems and data
as a form of“hacktivism.
