The internet has made the world to be a global village. The increasing access to and the continuous use of technology has greatly impacted how we communicate and conduct our daily activities. The internet connects people and computers to the outside world, and this has led to the emergence of Cybercrime. Criminals are becoming more sophisticated, and no one is safe – from individuals, public and private organizations. Additional layers of defense are needed to keep ourselves safe from the dark world.
Cybercrime is a serious crime involving computers and digital devices in which your device can be a target of a crime, a tool of crime or contain evidence of the crime. There are many types of cybercrime-related acts. To protect ourselves from attack, we need to understand all these threats.
1. Identity Theft
Identify theft and fraud is one of the most common types of cyber crimes. Identity theft is used to explain when a person purports to be some other person, with the aim of creating a fraud for financial gains. When such crime happens, we call it online identity theft. This is the most used way to steal information online and is the leading data breach affecting government and federal websites.
To protect from identity theft, ensure that your computer and devices are kept current with the latest patches and updates. Block any basic and automated attacks completely by the use of firewalls and antivirus.
Ransomware is one of the most lethal malware-based attacks. It enters your network to encrypt your files with a public key encryption. Unlike the other types of attacks, this encryption key remains on the hacker’s server. The attacked users are then asked to pay huge sums of money to receive the private key and have their data back.
To fight ransomware, you need to have anti-malware installed in your system. Pay attention to soliciting emails that may come your way. Never click suspicious links and attachments in emails. Stay safe
3. Denial of Service Attack
Denial of service attack occurs when online services are brought down and made unavailable for a certain period until the attacker’s demands are met. DoS occurs through directing a site with overwhelming traffic from multiple location and sources. Botnets – large networks of infected computers are developed and attack the victim’s computer. Hackers attack your computer with the sole aim of extortion and blackmail.
To stay, protect your computer with security software. Essential security software includes firewall and antivirus programs. Firewall is usually your first line of defence when it comes to controlling who can communicate with your computer online.
4. Spam and Phishing
Spam and phishing are two common types of cybercrimes. There is no much one can do to prevent the two. Spam is typically unwanted emails and messages that flock your inbox. Phishing is an act where cyber criminals use bait to lure you to give them the information they need.
You need to exercise caution to stay safe. Keep an eye out of phony email messages. Do not respond to messages sent to your email that asks for personal information. Steer clear of fraudulent websites that may be used to steal personal information.
