Types and remedies for Cyber-attacks

 Suddenly the mobile rang in the middle of the work, the message came. It says that the customer has to win a large sum of money and click on the link next to get it. The insidious hacker got full control of the mobile phone as soon as he clicked on the link believing the customer's message.

 Such incidents are happening all over the world. As soon as the word hacker was heard, a negative feeling arose in everyone. Ethical hackers emerged to eradicate cybercrime and punish these hackers. Those who knit them are skilled and determined to cut all the illegal nets. However, there are more hackers in the world than ethical hackers. Because many young people get involved in the world of crime by going for hacking as a hobby. Every year, many organizations have lost billions of dollars just because of this crime. Even people are being bullied.

 However, it has been possible to eliminate all the harmful effects of ethical hackers. They are trying to find a solution to the problem of cyber attacks so that they do not have to suffer many losses. They are researching the process by which cyber attacks can be carried out and how to prevent them. Let us know about the type of cyber attack and its remedy.

1) Botnet


Botnets are used to control the security of a computer by breaking the security system. Thus when many devices are attacked by malicious software and the possession of the device is given to the control of another third party, then each computer becomes a 'bot.' Botnet controllers then use network protocols such as the IRC and the Hypertext Transfer Protocol (HTTP). Basically, cybercriminals use most botnets for various purposes. It is basically sent via email. Different viruses are attached to the email, the device is infected as soon as it is opened.

Remedy

Emails from untrusted sources or emails from spam boxes cannot be opened. If there is a link in the email, you have to verify it first, then you have to work on it.

2) Distributed Denial of Service (DDOS)


A strategy to block the actual users of a resource or service in a computer system. By carrying out this attack on a computer or system or Internet website, the proper functioning of that system or site is slowed down or, in many cases, stopped altogether. This is mainly done on servers and websites.

Remedy

Using powerful paid anti-virus. Installing firewalls and restricting traffic to and from devices or servers. Emails received from untrusted sources are not open. Don't open emails from strangers and be wary of acquaintances. 

3) Malware:


It is a type of software used to disrupt the normal functioning of a computer or mobile phone, to collect confidential information, to infiltrate a protected computer network system, or to display unwanted advertisements. It can roam freely on the device without the user's permission.

Remedy

Do not download any software from untrusted websites. Please read the terms and conditions carefully before installing any software. Update the software you use regularly, but refrain from doing any security updates through pop-ups.

4) Phishing


Cybercriminals use it to the maximum. Because it is very easy to fool the victim and steal his information. Personal information is stolen by persuading victims to provide their information by making fake versions of an organization's mail, mobile messages, and websites. For example, Pallab is using Google to buy books online. Suddenly I saw an e-commerce company with the same book on two different websites but at a lower price. He ordered the book with a credit card, but the book was not found, but his bank money disappeared. Here that website is created by the hacker, and all the information given by Pallab is saved directly on the hackers' server. Its use in cyberspace is constantly harming people and organizations. It is difficult to understand at first sight as it is exactly the same as the original message.

Remedy

Beware of buying anything online, applying for a job, providing passwords, and providing personal information. If you see any tempting offer or price, check first and then work.

5) Ransomware


Ransomware is a type of malware that prevents a user from accessing a machine after infecting a computer device and restricts the user's access and demands a ransom from the user to remove this restriction. Some ransomware encrypts all the files on the system's hard drive with a big key. The encryption key is so large that it is technically impossible to break it without a ransom. Some also lock the user's system through a simple program and entice the user to pay a ransom through a message on display.

Remedy

Do not pay the ransom. These threats are used by hackers to intimidate you. Even if you submit a payment, there is no guarantee that you will regain access to your system. If your computer is infected (e.g., you can't access your computer, or your files are encrypted), contact a reputable computer technician or specialist to find out if your computer can be repaired and your data restored. Be sure to back up your data regularly via external storage drives to minimize the effects of a ransomware infection. Your files may be unexpected, but it is important to have an up-to-date backup. 

6) Spyware


Spyware is software that aims to collect information about a person or organization, sometimes without their knowledge, and to pass such information on to others without the consent of the customer. Also, spyware controls the device without the customer's knowledge and sends confidential information to any third party through the cookies without the customer's consent.

Remedy

Refrain from using all types of unverified links. Don't surf porn websites. Because it is on most websites, the device will be hacked as soon as you click on a picture or video. 

7) Virus


A computer virus is a type of computer program that destroys all kinds of information without the user's permission or idea. A virus can spread from one computer to another only when the infected computer is moved to a normal computer. For example, a user can transmit the virus through a network or spread it through a portable medium such as a floppy disk, CD, USB drive, or the Internet. Viruses can also infect a network file system, infecting other computers that use that system. Viruses are sometimes associated with computer worms and Trojan horses. A Trojan horse is a file that remains untouched until it is executed.

Remedy

Once a computer is infected with a virus, it is dangerous to use it without reinstalling the operating system. However, there are several ways to repair a virus-infected computer. These methods depend on the type of virus and the degree of infection. Need to use anti-virus. If a computer has a virus that cannot be removed by anti-virus software, a reinstall of the operating system may be necessary. To do this, you need to delete the hard drive completely (you need to delete and format the partition).
