Everything You Need to Know about Cyber Attacks 2022

A cyber attack is a cybercriminal attack that targets a single or multiple computers or networks using one or more computers. From a compromised computer, a cyber attack can be used to disable systems, steal data, or launch subsequent attacks. Cybercriminals use a variety of ways to conduct 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. Cyberattacks are designed to disable, disrupt, destroy, or seize control of computer systems, as well as change, block, wipe, edit, or steal data stored on them.

 

The various forms of cyberattacks

  1. Malware is a term used to describe malicious software that is utilised to launch attacks against computer systems. Ransomware, spyware, and Trojans are all types of malicious software. Depending on the type of malicious code that is deployed, hackers can use malware to steal or covertly copy sensitive data, restrict access to files, disrupt system functions, or render systems unusable. Malware can also be used to deny access to files.
  2. A technique known as “phishing” is a form of social engineering that uses electronic messages to attempt to convince recipients to open them. The recipients are tricked into downloading the virus that is contained within the email by either opening an attached file or clicking on a link that is embedded within the message.

 

  1. Man-in-the-middle assaults, also known as MitM attacks, take place when the perpetrators of the attack position themselves in the centre of two parties, such as individual computer users and their banking institution. Depending on the particulars of the assault, this type of attack can be referred to as a man-in-the-browser attack, a monster-in-the-middle assault, or a machine-in-the-middle assault. All of these names refer to the same type of attack. Another name for this type of attack is an eavesdropping attack.

 

  1. Distributed Denial of Service (DDoS) is a sort of cyberattack in which hackers flood a company’s servers with a large number of simultaneous data requests. This causes the servers to become overwhelmed and unable to process any other requests, including legitimate ones.

 

  1. SQL injection is when hackers use the programming language Structured Query Language to inject malicious code into servers in order to force the server to reveal sensitive data. This is done in order to gain access to the data stored on the server.

 

  1. An instance of a zero-day exploit takes place when malicious users take advantage of a recently found flaw in an information technology system for the first time.

 

  1. Domain name system (DNS) tunnelling is a sophisticated form of cyberattack in which the perpetrators of the attack create and then use a consistently available access point (also known as a tunnel) into the computer networks of the organisations they are attempting to compromise.

 

  1. Hackers carry out attacks based on credentials when they steal the credentials that IT professionals use to access and operate systems. They then use this information to gain unauthorised access to computers in order to steal important data or disrupt the operations of a business.

 

History of Cyber Attack

Let’s look at some of the most important cyberattacks that have ever happened.

 

 

1. The Melissa Virus

 

One of the first and most dangerous cyber threats was the Melissa Virus. In 1999, the Melissa Virus was released by programmer David Lee Smith. He did this by giving people a file that could be opened by Microsoft Word. The malware did a lot of damage to hundreds of companies, including Microsoft. It is expected that fixing the broken systems will cost more than $80 million.

 

2. NASA Cyber Attack

 

In 1999, 15-year-old James Jonathan was able to hack into NASA’s computers and shut them down for 21 days! About 1.7 million pieces of software were downloaded during the attack, which cost the space giant about $41,000 to fix.

 

3. The cyber attack on Estonia in 2007

 

In April 2007, Estonia experienced what is said to be the first cyber attack on a whole country. Around 58 Estonian websites, including government, banking, and media services, went offline.

 

4. An attack on Sony’s PlayStation Network over the Internet

 

In April 2011, a cyberattack on Sony’s PlayStation Network made the personal information of 77 million members public.

 

5. Adobe gets hacked

 

At first, it was thought that the cyber attack had exposed the personal information of 2.9 million users. However, it ended up exposing the personal information of up to 38 million people. Adobe says that only the first 2.9M people had their passwords and credit card information stolen, while the other 35.1M only had their passwords and IDs stolen.

 

6. The attack on Yahoo in 2014

 

In 2014, one of the biggest cyber attacks happened when 500 million Yahoo accounts were hacked. But basic information and passwords were supposedly gotten, but not bank information.

 

7. An attack on Ukraine’s power grid

 

In 2015, almost half of the homes in the Ivano-Frankivsk area of Ukraine lost power for a few hours because of the first cyberattack on a power grid.

 

8. The WannaCry Ransomware Cyber Attack of 2017

 

In 2017, over 200,000 systems in over 150 countries were hit by one of the biggest ransomware attacks ever. This outbreak had a big effect on many businesses and cost almost 6 billion pounds to fix.

 

9. A cyberattack on Marriott Hotels went on for years without anyone noticing.

 

A cyber attack had been going on for a long time when Marriott bought the Starwood Hotels group, but it wasn’t discovered until 2018. But by that time, the attacker still had access to the personal information of the guests. The information of about 339 million guests has been made public. Because of this, the UK’s data privacy authorities gave the Marriott Hotels a fine of 18.4 million pounds.

Cyber Attack Safety Measures

The Best Ways to Stop Cyber Attacks in 2022

 

  1. Update your software regularly

 

One of the most important things you can do to stop ransomware is to update old software, both operating systems and applications. This helps get rid of important security holes that hackers use to get into your devices. Here are a few suggestions to get you started:

 

  • Set your device to get system updates on its own.

 

  • Make sure that your desktop web browser automatically checks for and instals security updates.

 

  • Make sure the plugins in your web browser, like Flash and Java, are up to date.

 

  1. Utilize Antivirus Protection with a Firewall

Anti-virus (AV) protection software has been the most extensively utilised method for combating malicious threats. Antivirus software prevents malware and other harmful viruses from entering your device and destroying your data. Utilize only one anti-virus tool on your device, and ensure that it comes from a trusted provider.

Utilizing a firewall to safeguard your data from malicious threats is crucial. A firewall safeguards your device by screening out hackers, malware, and other malicious behaviour that occurs over the Internet and by determining which traffic is permitted to enter. Windows and Mac OS X each have their own firewalls, which are appropriately named Windows Firewall and Mac Firewall, respectively. Your router should feature a firewall to safeguard your network from threats.

 

  1. Use Robust Passwords and Password Management Software

 

Choose a password with at least eight characters, one number, one capital letter, and one special character. Do not use passwords that are easily guessed. Strong passwords are essential for preventing hacking.

 

  1. Employ Two-Factor Authentication or Multi-Factor Authentication

Two-factor authentication, often known as multi-factor authentication, is a service that adds additional security layers to the conventional password-based way of establishing online identification. Typically, you would enter a username and password without two-factor authentication. If you use two-factor authentication, however, you will be required to submit an additional authentication method, such as a Personal Identification Code, an additional password, or even your fingerprint. Multi-factor authentication requires you to enter more than two additional authentication methods in addition to your username and password.…
