Cyber Crime

N kavya

Cybercrime is any criminal activity that involves a computer, networked device, or network. cybercrimes are carried out to generate profit for the cybercriminals, some cybercrimes are carried out against computers or devices directly to damage or disable them. 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. A primary effect of cybercrime is financial. Cybercrime can include many types of profit-driven criminal activity, including ransomware attacks, email and internet fraud, identity fraud, and attempts to steal financial accounts, credit cards, or other payment card information. Cybercriminals may target an individual’s private information or corporate data for theft and resale. As many workers settle into remote work routines due to the pandemic, cybercrimes are expected to grow in frequency in 2021, making it especially important to back up the data.

The U.S. Department of Justice (DDJ) divides cybercrime into three categories :
1. Crimes in which the computing device is the target
2. Crimes in which the computer is used as a weapon
3. Crimes in which the computer is used as an accessory to a crime

Cybercriminal activity may be carried out by individuals or groups with relatively little technical skill, or by highly organized global criminal groups that may include skilled developers and others with relevant expertise. Cybercriminals often choose to operate in countries with weak or non-existent cybercrime laws to further reduce the chances of detection and prosecution.

Types of Cybercrime -:

1. Cyberextortion: A crime involving an attack or threat of an attack coupled with a demand for money to stop the attack.
2. Crypto-jacking: An attack that uses scripts to mine cryptocurrencies within browsers without the user’s consent.
3. Identity Theft: An attack that occurs when an individual accesses a computer to glean a user’s personal information, which they then use to steal that person’s identity or access their valuable accounts, such as banking and credit cards.
4. Credit card Fraud: An attack occurs when hackers infiltrate retailers’ systems to get their customers’ credit card and/or banking information.
5. Cyber espionage: A crime involving a cyber-criminal who hacks into systems or networks to gain access to confidential information held by a government or other organization.
6. Software-Piracy: An attack that involves the unlawful copying, distribution, and use of software programs with the intention of commercial or personal use.
7. Ransomware attacks are similar, but the malware acts by encrypting or shutting down victim systems until a ransom is paid.
8. Phishing: The most common type of cybercrime as reported to the U.S. Internet Crime Complaint Centre was phishing and similar fraud.
9. Website Spoofing & IOT Hacking.

Cybercrime & Its Impact on Society – : On an individual level, a cyber-attack can lead to a variety of consequences, ranging from theft of personal information to extortion of money or loss of valuable data, such as family photos. Society and systems depend on critical infrastructures, such as power plants, hospitals, and financial services companies. The protection of these and other organizations is essential for the maintenance of our society and support of the relations between countries and international organizations.

How to prevent Cyber Crime –:

Backup all data, system, and considerations: This enables data stored earlier to assist businesses in recovering from an unplanned event.


• Enforce concrete security and keep it up to date: Choose a firewall with features that protect against malicious hackers, malware, and viruses. This enables businesses to identify and respond to threats more quickly.


• Never give out personal information to a stranger: They can use the information to commit fraud.


• Check security settings to prevent cybercrime: A cyber firewall checks your network settings to see if anyone has logged into your computer.


• Using antivirus software: Using antivirus software helps to recognize any threat or malware before it infects the computer system. Never use cracked software as it may impose the serious risk of data loss or malware attack.


• When visiting unauthorized websites, keep your information secure: Using phishing websites, information can easily bypass the data.


• Use virtual private networks (VPNs): VPNs enable us to hide our IP addresses.


• Restriction on access to your most valuable data: Make a folder, if possible, so that no one can see confidential documents.
