1. Cybercrime

2. Cybercrime
Cybercrime is any criminal activity that involves a computer, networked device or a network.
While most cybercrimes are carried out in order to generate profit for the cybercriminals, some
cybercrimes are carried out against computers or devices directly to damage or disable them,
while others use computers or networks to spread malware, illegal information, images or
other materials. Some cybercrimes do both -- i.e., Target computers to infect them with a
computer virus, which is then spread to other machines and, sometimes, entire networks.

 Crimes in which the computer is used as a weapon -- for example, to launch a denial-of-service (dos) attack; and
 Crimes in which the computer is used as an accessory to a crime

4. Effects of cybercrime
Cybercrimes may have public health and national security implications, making computer crime one of do's top
priorities. In the united states, at the federal level, the federal bureau of investigation's (FBI) cyber division is the
agency within DOJ that is charged with combating cybercrime. The department of homeland security (DHS)
sees strengthening the security and resilience of cyberspace as an important homeland security mission, and
agencies such as the U.S. Secret service (USSS) and U.S. Immigration and customs enforcement (ICE) have
special divisions dedicated to combating cybercrime.

5. How cybercrime works
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These
cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money
from users; or interrupting normal business processes.
Cybercrime attacks can begin wherever there is digital data, opportunity and motive. Cybercriminals include
everyone from the lone user engaged in cyberbullying to state-sponsored actors, like china's intelligence
services. Cybercrimes generally do not occur in a vacuum; they are, in many ways, distributed in nature. That
is, cybercriminals typically rely on other actors to complete the crime, whether it's the creator of malware
using the dark web to sell code, the distributor of illegal pharmaceuticals using cryptocurrency brokers to
hold virtual money in escrow or state threat actors relying on technology subcontractors to steal intellectual
property (IP).

6. How to prevent cybercrime
 Some steps for resisting cybercrime include the following:
 Develop clear policies and procedures for the business and employees
 Create cybersecurity incident response management plans to support these policies and procedures
 Outline the security measures that are in place about how to protect systems and corporate data
 Use two-factor authentication (2faa) apps or physical security keys
 Activate 2FA on every online account when possible
 Verbally verify the authenticity of requests to send money by talking to a financial manager
 Create intrusion detection system (IDS) rules that flag emails with extensions similar to company emails
 Carefully scrutinize all email requests for transfer of funds to determine if the requests are out of the ordinary
 Continually train employees on cybersecurity policies and procedures and what to do in the event of security
breaches

7. Why is cybersecurity important?
In today’s connected world, everyone benefits from advanced cyber defense programs. At an individual
level, a cybersecurity attack can result in everything from identity theft, to extortion attempts, to the loss
of important data like family photos. Everyone relies on critical infrastructure like power plants,
hospitals, and financial service companies. Securing these and other organizations is essential to
keeping our society functioning.
Everyone also benefits from the work of cyber threat researchers, like the team of 250 threat researchers
at talos, who investigate new and emerging threats and cyber attack strategies. They reveal new
vulnerabilities, educate the public on the importance of cybersecurity, and strengthen open source tools.
Their work makes the internet safer for everyone.
