Online Cyber Attacks

Online Cyber Attacks are increasing day by day with new methods of compromising the victims on the internet. According to the stats, around 9 Million clients are affected by Cyber Attacks every day. There are many types of cyber-attacks that are performed to steal the user data and identity for several personal and financial benefits. Cyber attacks are the beginning of a new era of theft and fraud from online resources.

What are Cyber Attacks?

A cyberattack is an online crime through which the attacker tries to deceive the user to breach into their field of working environment. Cyberattacks are mainly used for data theft and information leaks to destabilize the economy and assets of a business. According to Cisco’s annual report, the number of cyberattacks has increased four times as of 2017, with above 50% of the cyberattacks leading to the expense of $0.5 million.

Types of Cyber Attacks

There are several types of cyber-attacking strategies that are increasing day by day, fraudsters are always figuring out different ways of exploiting user data for personal benefits. These are some of the different kinds of cyberattacks explained in this blog:

Malware

Malware is concerned with any malicious or infected file which gets into the system to spy or transfer the data towards the unrecognized network. It can flow into a system by unverified links planted by the attacks, that is the reason why many popular mailing engines such as Gmail always filter out the emails and move malicious emails into the spam folder. A malware-affected system can deny access to different critical resources of the network, retransfer data to different networks, and can disrupt the workflow of a system.

A computer virus is a form of Malware that continuously multiplies itself to infect and replicate the code of a computer system. The way of identifying a virus is through its extensions at the end of the file name, for e.g. .exe in windows operating systems

Phishing

The online technique of luring a user into a trap to gather account information and passwords is called phishing attacks. It is mainly in the form of fake links, fraudulent emails, and messages which are disguised as coming from a reliable source.

Phishing is an old technique to dupe the user to input the information required by the attackers, It can take place through social media sites, emails, direct messages, or clicking unusual links online. The keypresses and clicks are monitored in this technique to gather sensitive data such as pins and passwords.

Phishing is also of several types such as spear phishing which works on directing attacks on different companies, whaling which is associated with targeting stakeholders within an organization, and pharming which exploits the domain name server of the company to capture user credentials.

DOS Attack

DOS attacks or denial of service attacks are caused by overusing the system resources and bundles. It is a technique in which the servers of the system are flooded with unusual traffic to overload the network and the bandwidth of the connection. The purpose of the DOS attack is to make the system unresponsive to disrupt the connection which leads to denial of service to the original requests from the client.

Another modification of the DOS attack is the DDOS (Distributed Denial of Service) attack which is from several machines with the goal of completely crashing the original system and taking it offline. Tea drop attacks, ping of death, and botnets attacks are common examples of DDOS attacks.

SQL Injections

SQL stands for Structured query language, it is the language that is used by most of the database systems on the internet. SQL injection is the attack in which the fraudster injects modified code in the form of a database query into the server of the system, which in turn leaks out sensitive information from the repository. Many attackers insert malicious code into the search boxes and comment sections of websites, Weakly protected databases with no parameterized query at the backend of the database allow the execution of malicious code which leads to costly results for the business.

How to Tackle Cyber Attacks?

Cyberattacks are the cause of many expensive failures among different systems of a business. To prevent cyberattacks these precautionary measures must be taken in order to ensure the system’s security and health.

  1. Setting up firewalls: To improve the data flow inside the computer system, Firewalls can help in protecting the network with an additional layer of security.
  1. Always Backup your Data: Backing up the data is the best way of getting back up after being hit by a cyberattack, with data safe at another server, The organization can regroup and reconsolidate the expense of the attack.
  1. Control the System Access: Restricting access to the server ensures data Security for a limited number of users across the system. Limited access helps in preventing unauthorized access and data theft from the repository.
  1. Choosing a Strong Authentication Method: Using a weak pin/password is risky as attackers might get their hands on the data through different strategies of keylogging attacks, A biometric facial recognition authentication method helps in secure authorizations without any vulnerabilities.

Conclusion

Cybersecurity is one of the major concerns of today’s world, with several strategies for online attacks, systems are getting more and more vulnerable in preventing the issues associated with online scams. There are many precautions for reducing the risks of online attacks such as limiting user access, ransomware protection, and data backup.
