Crimes against property

an owner of property, whether or not violence is used or
threatened. These crimes affect another person's rights of
ownership or possession of property, such as money, cars,
jewelry, or drugs. Some examples of crimes against

misuse of someone’s personal

Phishing
Phishing is a form of social
engineering and scam where attackers deceive
people into revealing sensitive information or
installing malware such as ransomware. Phishing
attacks have become increasingly sophisticated
and often transparently mirror the site being
targeted, allowing the attacker to observe
everything while the victim is navigating the site,
and transverse any additional security boundaries
with the victim.
Presentation title 12
Pharming
Pharming is a cyberattack intended to redirect a website's traffic to
another, fake site by installing a malicious program on the computer.
Pharming can be conducted either by changing the hosts file on a
victim's computer or by exploitation of a vulnerability in DNS
server software. DNS servers are computers responsible for resolving
Internet names into their real IP addresses. Compromised DNS servers
are sometimes referred to as "poisoned". Pharming requires
unprotected access to target a computer, such as altering a customer's
home computer, rather than a corporate business server

attack to cause large scale disorder in
computer networks. This category can
cause panic amongst the civilians. In this
category, criminals hack government
websites, military websites, or circulate
propaganda.
