A cyber-attack may be defined as a malevolent effort to compromise other systems in order to render them inoperable, steal data, or do some other horrible act. Oftentimes, the purpose of a cyber-attack is to extort ransom from the victims. We've prepared a list of many types of cyber assaults and their protection strategies in this post.
Cyber-attack doesn’t need much introduction. This is the one-act, which is most hated by everybody, be it an individual or an organization, across the world. Because, the magnitude of the havoc caused by some of the cyber-attacks such as WannaCry, NotPetya, Capitol One breach, Citrix breach, and Ethereum, etc. is still in the memory of many people. If one thinks cyber-attacks are not frequent then it is a wrong notion. The truth is they occur almost every day in some parts of the world.
In simple terms, a cyber-attack can be termed as a malicious attempt to break into the other systems to make them non-functional, steal data, or to do some other heinous crime. Many a time, the willful intention behind a cyber-attack is to demand ransom from the victims. Though there are constant attempts to contain the cyber-attacks, the attackers always use innovative methods or types to intrude into the other computer systems and to hack them.

Phishing is one of the common forms of cybercrime launched to attack the targets. Using this method, the hackers send malicious emails to the targets. These emails give the impression that they are sent from a known person or some trusted source. In some cases, these phishing emails contain even attachments to dupe the recipient. In other words, these phishing emails are sent in such a way that they look legitimate in every aspect. If clicked, the targets fall prey to the hackers’ trap and with whatever intention the hacker sent that email it will be achieved instantly.

Once the malware is installed in your system, it wreaks havoc. You cannot have access to the key components of the network. Your data from the hard drive will be stolen. You cannot operate your system. Viruses such as Micro Virus infect important applications such as Microsoft Word or Microsoft Excel and make them non-functional.
Denial of Service or DoS is a kind of cyber-attack that floods a website or an application with artificial traffic more than the volume it can handle.

In this attack, the hackers won’t look for an action from the user to install the malware in their systems. Instead, they add the malicious code in the HTTP or PHP code on a page of the website or web application. What happens now is – when somebody visits that page containing malicious code, the malware gets installed in that visitor’s system. Websites or applications, which are not secured, are the primary targets in this kind of attack.
This is one of the common methods of the illegitimate way of accessing other systems in a network. As part of launching this attack, the hackers steal the passwords from a person’s desk or sniff the connection between a system and a network. The hackers also use the Brute force method to guess the passwords randomly. In order to guess a password, they try using the target’s details such as name, occupation, and job title, etc. Another method the hackers use to obtain passwords is the Dictionary attack. In the dictionary attack, the hackers use an encrypted password and apply the same encryption to a dictionary of passwords that are used commonly and then check the results.
