Everything You Need to Know about Cyber Attacks

A cyber attack is a cybercriminal attack in which one or more computers are used to target a single or multiple computers or networks. A cyber attack can be used to disable systems intentionally, steal data, or launch additional attacks from a compromised computer. Cybercriminals use a variety of methods to launch a cyber attack, including malware, phishing, ransomware, and denial of service, among others.

A cyber attack is any attempt to gain unauthorised access to a computer, computing system, or computer network with the intent of causing harm. Cyber attacks are designed to disable, disrupt, destroy, or take control of computer systems, as well as change, block, erase, modify, or steal data stored on them.


Types of cyberattacks

  1. The term malware refers to malicious software that is used to assault computers. Ransomware, spyware, and Trojan horses are all types of malware. In order to steal or copy sensitive data, limit file access, disrupt system operations, or render systems unusable, malicious code can be employed by hackers.
  2. Phishing is a technique used to trick people into opening bogus email messages. The recipients are tricked into downloading a virus when they open an attached file or click on an embedded link in the email.


  1. In a man-in-the-middle (MitM) attack, an attacker is placed in the centre of two parties, such as an individual computer user and their bank. It is possible to label this attack as a “man in the browser,” “monster in the middle,” “machine in the centre,” or “monster in the middle.” Another name for it is an eavesdropping assault.


  1. In a DDoS assault, the servers of a corporation are bombarded with so many simultaneous data demands that the servers become unresponsive to any legitimate requests.


  1. Using the Structured Query Language programming language, hackers can use SQL injection to inject malicious code into servers and force them to divulge sensitive information.


  1. A zero-day exploit occurs when a newly discovered IT infrastructure vulnerability is first exploited by hackers.


  1. Using DNS tunnelling, attackers get access to their targets’ systems by establishing and then using a tunnel that remains open at all times.


  1. These attacks are called credential-based attacks because they occur when hackers steal IT professionals’ credentials, then utilise that information for unauthorised access to computers so that they can steal crucial information or disrupt a company.

History of Cyberattacks

A look back at some of the most major cyberattacks in history.


1. The Melissa Virus.


An early and most dangerous computer virus was Melissa. The Melissa Virus was published in 1999 by programmer David Lee Smith by distributing a file that could be opened by Microsoft Word. One of the most destructive viruses in history infected hundreds of companies, including Microsoft. Over $80 million will be needed to fix the affected systems.


2. A cyber attack against NASA


In 1999, a 15-year-old boy named James Jonathan was able to shut down NASA’s computers for 21 days. SpaceX had to pay $41,000 in repairs after 1.7 million pieces of software were downloaded during this attack on the space station.


3. A cyber attack on the Estonian government occurred in 2007


The first cyber strike on a full country occurred in Estonia in April 2007 when 58 Estonian websites, including government, banking, and media services, were taken offline by hackers.


4. Sony’s PlayStation Network was the victim of a cyber attack


77 million PlayStation Network users’ personal information was compromised in an online attack on Sony’s PlayStation Network in April 2011.


5. Cyberattack against Adobe Systems, Inc.


Cyber attacks that were supposed to affect only 2.9 million persons turned out to affect as many as 38 million people! A total of 2.9 million people had their passwords and credit card information stolen, however Adobe maintains that just 35.1 million people had their passwords and ID stolen.


6. Cyberattack against Yahoo in 2014


It was one of the year’s biggest cyber attacks when 500 million Yahoo accounts were hacked in 2014. Basic information and passwords were purportedly taken, but financial information was reportedly kept out of the hands of the hackers.


7. Attack on Ukraine’s Power Grid


Almost half of the homes in Ukraine’s Ivano-Frankivsk district lost power for a few hours in 2015 in what was the first cyberattack on a power grid.


8. Ransomware Cyberattack of 2017: WannaCry


There were nearly 200,000 affected systems in over 150 countries, making this year’s ransomware attack the greatest ever. Many businesses were severely affected and the world lost over $6 billion as a result of this pandemic.


9. Marriott Hotels were the victim of a cyber attack that remained unreported for years


It wasn’t until 2018 that a cyber attack on Marriott’s Starwood Hotels acquisition was made public, despite the fact that it had been ongoing for some time. As a result, the assailant still had access to the guests’ private information. The personal information of an estimated 339 million visitors has been leaked, according to reports. The UK’s data privacy authorities penalised Marriott Hotels 18.4 million pounds as a result of this.




Preparation for less damage in a Cyberattack


Anti-Cyberattack Tips for 2022


1. Ensure that your software is current


One of the most important cyber security measures for combating ransomware is patching out-of-date software, including operating systems and applications. As a result, hackers will be unable to take advantage of critical flaws in your system. The following are a few tips to help you get off the ground:


  • Use the automatic system upgrade feature to keep your device up to date.


  • Use an automatic download and installation of security updates for your desktop browser.


  • It’s important to keep Flash and Java installed on your browser up to date.



2. Install anti-virus software and a firewall

Anti-virus (AV) protection software has been the most widely used approach to combating malicious attacks. Antivirus software prevents malware and other dangerous viruses from infiltrating your device and corrupting your data. On your device, use only one anti-virus tool from a reputable vendor.

Using a firewall to protect your data from malicious attacks is critical. A firewall protects your device by filtering out hackers, malware, and other potentially harmful Internet activity and deciding what traffic is allowed to enter. Windows and Mac OS X each have their own firewalls, appropriately named Windows Firewall and Mac Firewall. Your router should include a firewall to protect your network from threats.


3. Make Use of Strong Passwords and a Password Management Tool


Choose a password that contains at least 8 characters, including one number, one upper case letter, and one special symbol. Passwords that are easy to guess should be avoided. Strong passwords are essential for keeping hackers at bay.


4. Make use of two-factor or multi-factor authentication


Two-factor authentication, also known as multi-factor authentication, is a service that adds layers of security to the traditional password-based method of establishing online identity. Without two-factor authentication, you would normally enter a username and password. If you use two-factor authentication, however, you will be required to provide an additional authentication method such as a Personal Identification Code, another password, or even your fingerprint. With multi-factor authentication, you must enter more than two additional authentication methods after entering your login and password. Contact the best Cyber security company in India.
