As our civilization is going more and more advanced day by day, we are facing more and more cyber attacks. These are the threats that caused by preying peoples called hackers and lives on our own money. They somehow manage to get access to private things such as calls, bank accounts, personal credentials, etc. That is why cybersecurity is necessary for stopping these anonymous persons from doing a cyber attack.
For making a secure cyber network, we must understand first what is a cyber attack and how many different categories it can be classified. Let’s discuss all of them.
Types of Cyber Attack:
The word “Virus” brings fear upon us nowadays. Well, a computer virus works the same as a biological virus. It is a self-replicating program that superfluously makes its copies, slowing down the whole system and spreads everywhere.
A more intense computer virus can also damage all the files from your computer by unnecessarily replicating itself and your hardware even stops working. Once a virus is made, it cannot be stopped but just can be formated.
That is why a whole system format is required to clean your laptop/pc. This may also cost your data. Some of the very advanced viruses can also steal your private information and sends it back to its owner! That is why good antivirus protection is required.
There are many different types of malwares present on the open internet that is made to access your device somehow and steal your private information. Some of the examples of famous malware are given below.
Adware is a type of malware family that is famous for showing annoying ads and pop-ups. A hacker develops software that shows ads on an anonymous website. If you accidentally click on that add then that will lead to a software download which is made by the hacker. Once installed it can cause harm or steal your important data also without even known anyone.
- Trojan horse
This is another type of malware that behaves as essential software. It pretends to be useful for the users and once downloaded it gains access to every hardware and software on your device. Trojan triggers many malicious actions simultaneously on your computer. It cannot make its copy but it can install many viruses without any permission. What if you find out that you cannot open your laptop with your password. It is locked and gone!
Ransomware is a type of virus that easily accesses anyone’s computer/laptop. It is mainly used by hackers to cheat people. It is very easy to access and malfunction anyone’s system using this. Confidential information is looted by the hacker and they ask for a ransom of money in return for their details. They blackmail by threatening to release private information publically and ransoms money.
4. Phishing and Spehre Phishing attacks
This is a type of fraud in which spam emails are sent to anyone. This email pretends to have its origin in a big or small adorable company and tries to shows its honesty. But that contains malware files and links that can access any device once they are allowed to run on the device.
You might not even know and you click on allow anywhere, even if by accident, it has done its work. You will lose important files and even get fraud by blackmailing.
5. Man-In-The-Middle Attack
In this case, the hacker manages to get access to the information path between your device and server. The hacker gets your IP address and secretly intercepts the communication line between you and the website server. This mainly happens in the public Wi-Fi areas. Everyone who is accessing the Wi-Fi publically is surely at risk of getting a man-in-the-middle attack.
The most efficient way to prevent this using public Wi-Fi is to use a VPN. VPNs are virtual private network applications that will change your IP address while connecting to the internet. This makes a more secure connection.
6. Denial of Service(DOS) and Distributed Denial Of Service Attack
You can get very detailed information about DOS and DDOS in our previous article by clicking here. This attack has a continuous transmission of unnecessary logs and files across a busy network.
Hence the excessive amount of files transferring through the same network will create a denial of service, or say interrupts the whole network. Hence system or server goes down due to excessive traffic.
7. Password attack
Cyber terrorists mainly use password authentication mechanisms to gain access to user’s passwords and accounts. Brute force is one of the forms of password attack in which the algorithm guesses your password. It is used with advanced tools which help decipher password based on serval factors.
8. SQL injection attack
It occurs when intruders inject malicious code into the databases that are present on the SQL server. SQL is one of the largest used database servers all over the world. This can corrupt, destroy or maybe even steal information from the database.
9. ATM fraud
In this type of attack, the hacker tries to get access to ATM credentials, pin numbers, and account details so the attacker can use these credentials to get money.
10. Sharing copyright files or information
Cyber terrorist tries to get access to copyrighted files and confidential information and uses against them or steal them.
11. Drive-by attack
Cyber terrorists frequently use Drive-by attacks to spread malwares. They tend to find an insecure website that has only the “HTTP” protocol, not the secure “HTTPS” protocol. Once they find a victim, they inject different types of malware into his/her system using the HTTP or PHP code of that website.
12. Spam attack
In this type of attack, the hacker tries to create spam emails and messages which in bulk send to many different users randomly. These emails have malicious files and malware enough to corrupt your system.
13. Botnet attack
Botnets are the collection of a huge network which is made by cyber terrorists. These networks have injected malwares into it already. So it is like an ocean of malware, a network where you will surely become a victim of a cyber attack. Hackers use these systems with malware to carry out DOS and DDOS attacks.
14. Social engineering attack
Hackers use social engineering to access the personal data of the victims. They also use this for hijacking or gaining personal accounts and uses it as a threat or transferring money to different accounts.
15. Cross-site scripting attack
16. Key logger attack
This includes the use of programs that can take your keystrokes and pins to get your passwords. They can also get your sign ID whenever you try to log in to your account.
17. The Dictionary attack
Here a dictionary is used which contains a list of different common passwords which occur very frequently. This helps hackers to get targeted passwords.
18. Inside attack and data breaches
This happens in some companies where one field is replaced by another person. The employees or ex-employees are responsible. He/she can get a previous user’s account credentials and perform an inside attack pretending someone else.
19. Crypto-Jacking attacks
IT targets mainly the bandwidth of victim’s computers and breaks into their network security systems. Mainly done to mine cryptocurrency.
20. Crypto mining malware attacks
This cyber-attack consists of attacking a crypto-miner target and exchanges or hijack their computer’s processing power.
If you find any of these cyber attacks happening with you, inform to Cyber Cell Delhi branch, or any cyber cell near to you. Hope you find this helpful.
