    Computer security threats are relentlessly inventive. The threats continuously evolve to steal, harm, or annoy. Computer virus, Spyware threats, hackers and predators, and phishing are good examples of online cybersecurity threats. You, therefore, need to arm yourself with resources of handling these complex growing computer security threats. Most businesses all over the world have lost much of their money because of these threats.

    Computer Viruses

    Computer Viruses are well-known among many people including computer illiterates. They are programs that alter or affect the operation of your computer without your permission. They execute themselves thus damaging your computer. However, you can solve the issue by carefully evaluating and downloading free software from the peer-to-peer file sharing sites. You can also protect your computer using your web browsers through security settings by ramping it up for optimum defense against threats. Stay safe by learning the best ways of combating computer virus threats.

    Spyware Threats

    Serious threats to your computers! They are defined as programs monitoring your online activities and can install certain programs without your permission. Hackers use these programs to profit or capture useful information of an organization. The best way of handling these threats is by avoiding dealing with online companies you don’t know. You will find many companies advertising deals that seem to be good and true; their aim is, however, to obtain your personal information.

    Hackers and Predators

    These are not computer-generated threats. They are created by human being particularly computer experts. Both hackers and predators are programmers victimizing other peoples for their personal interests. They break into your computer and steal important information like credit card information and then destroy the data as a form of cyber-terrorism. They can also steal your identity and use it for malicious purpose. Apply online identity tools to safeguard you and your computer from the hackers.

    Phishing

    Phishers are very sensitive to your financial or personal information. They use fraudulent and instant messages to get your attention. It is important not to reply to messages like ‘your account has been blocked click here to activate it.” Clicking there means you are permitting them to access your account unknowingly. Therefore, it is important to ignore messages sent to you by unrecognized companies.

    While the threats mentioned above are most common, there is an advancement on the cyber threats due to an increasing focus on artificial intelligence, machine learning, and IoT devices.

    Memory-scraping malware: It is a malicious code that helps malicious hackers steal personal information. The malware taps into memory to look for sensitive information that is not available through other processes. Since data encryption is now widespread, memory scraping malware attempts to find weak spots to access data. For example, various memory-scraping malware steals encrypted data from applications at the point where data is transmitted unencrypted. Thus, many security mechanisms are compromised at this point. To avoid these shortcomings, users are advised to use secure web browsers with a memory sandbox.

    Exploit Kit: Exploit Kits are building blocks for malware. They typically have a graphical interface that allows even non-technical users to manage sophisticated attacks. It will enable you to build botnets, DoS exploits, and steal corporate data. The kits are created by professional developers who mostly exploit publicly known vulnerabilities in browsers and on clients. Among other things, the kits are available in underground forums, and prices often vary between three and five digit US dollar amounts. Since the sale of exploit kits make significant profits, the vendors have based their distribution model on the legitimate software vendor. Say, there are different license options and customer service components.

    They usually have the following characteristics – a web-based dashboard for managing the data generated by the infected systems; an interface that simplifies the distribution of malware through email, online advertising, or social networking; a simple click environment for creating the malware and the possibility of attacking in different languages.

    Distributed Denial-of-Service (DDoS) attack: The attack mobilizes a large number of infiltrated systems to attack a single target. The target system can not cope with this rush and is therefore no longer accessible to its users. The flood of incoming messages into the system forces the shutdown of the system and thus also services provided by this system to legitimate users. The computer controlled by the hacker is called a zombie or bot. A group of infiltrated computers is called a botnet or zombie army. Both Kaspersky Labs and Symantec consider botnets to be the biggest threat to the security of the Internet.

    raising the awareness is the key to a better cyber space atmosphere and usage.
