This article has been prepared for users who have heard nothing about ransomware and for users who do not care about it. We will explain what ransomware is in a practical and understandable language. We will also explain why even careful users should be afraid of ransomware and how you can be fully protected against it.


What is ransomware?

Ransomware is malware that is evolving and becoming more common every day. There are basically two types : encryptors and lockers.

When your computer is infected with an encryptor, it encrypts all kinds of data (files, photos, save files of games, databases, etc.) on your computer. Once the files are encrypted, you cannot open the files and you cannot access the data in the file. The criminals who carry out these attacks demand a ransom in exchange for a private key that can open your files. The average ransom amount demanded is around $300.

The reason why the other type is called a locker is that this malware locks the entire device. So not only your files, but your entire system will be inaccessible. But strangely, the ransom amount that the lockers demand is not as high as that of the cryptors.

Why you need to know about ransomware

First of all, there are a lot of ransomware out there. They threaten all Windows, Mac OS X, Linux and Android devices. In short, all desktop and mobile devices are under threat. However, ransomware mainly targets Windows and Android devices.

It is also very easy to infect your device. Very commonly, ransomware infects a computer through suspicious attachments opened, suspicious links clicked, and third-party sites from which apps are downloaded. Also, ransomware can infect legitimate websites: as a current example, cybercriminals use ad networks to infect users with ransomware .

On the other hand, it’s very simple to make users think they’ve downloaded and opened something important. An e-mail from the bank or an important program download. When the file is opened or the program is installed, the user installs ransomware on their computer.

Probably the main problem with ransomware is that deleting the malware does not solve the problem. A good antivirus program, and certain applications in particular, often offer a very effective solution to ransomware. But if the malware encrypts your files, you have to open the password to access your data.

Moreover, paying the ransom is very annoying for several reasons. First, you may not have the money to pay the ransom. Second, paying the ransom motivates the cybercriminals to keep going. Third, and most importantly, you cannot be sure that your problem will be resolved after paying the ransom. Ransomware, according to our research. Also, why did he trust someone who harmed you once and for the money he wanted, 20% of the victims could not recover their files even though they paid a ransom . It’s not very surprising. You can’t expect criminals to be just, so send them?

How to decrypt files
If ransomware has entered your system and encrypted your files, you cannot decrypt them yourself.
In such a situation, there are two ways you can choose.
You can pay the ransom by surrender – which we strongly do not recommend, for the reasons we listed above.
The other option is
to visit
noransom.kaspersky.com to see if there is a free
decryptor program that can open your files.
Our ransomware decryption tools are completely free, but unfortunately not all encryptors have solutions.
By the way, take your precautions without waiting for anything bad to happen.
How to protect yourself from ransomware
1. Do not open suspicious e-mail attachments, do not visit unknown websites, and do not download applications from non-official sources.
Learn about
phishing attacks and don’t click on phishing links.

2. Back up your files regularly.
If you have backups, you can restore your backup files (your backups can be found in the cloud or on external disks) after you have cleaned the ransomware on your computer with your antivirus program.

3. Use a good anti virus program.
Kaspersky Internet SecurityYou can try , it especially protects against ransomware, thanks to the special “System Monitor” module included in our program.
Meanwhile, according to independent tests, Kaspersky Internet Security
achieved 100% success against the ransomware tried

A few weeks ago we wrote a detailed post about ransomware . If you want, you can browse and get detailed information. By following our blog, you can learn the latest and up-to-date news about ransomware .

 

What is Ransomware? Learn How to Remove It

What is Ransomware? Simply put, it is a form of malware in cryptology that threatens to leak the victim’s sensitive information or permanently deny access to it without payment. The most common form of this malware is spyware. Spyware generally collects data from the computer and sends it to a destination. For example, your computer may have been infected with spyware that records your browsing habits and sends the information to online advertisers.

As an internet security threat, Ransomware can have serious consequences for both the user and the organisations that use the infected PC. Because the malware corrupts system files, it is impossible to open the damaged files normally. In addition, if the user does not pay the ransom, the attackers have the ability to wipe your hard drive, thus effectively deleting any trace of the original infection. This makes it essential for businesses and organizations to deal with this form of malicious software quickly and efficiently.

What is the goal of the criminals behind Ransomware? The most common objectives of criminals are to steal financial data (or blackmail the victim), collect confidential user information (such as passwords and bank accounts), and/or install a remote control program that allows them to access the infected computer. As an internet security threat, Ransomware has been known to have caused slow speeds on the majority of computers, reduced system performance, browser hijacks, and other issues that hinder normal internet usage. As an example, if an organisation’s internal banking applications has been compromised, decryption key will allow hackers to access this information and take money out of the bank accounts.

What are some signs that a computer may be infected with Ransomware? Since the advent of modern internet technology, it is possible to open emails from senders that contain a link that once clicked leads to a fake website that offers some type of free download or application. Many internet users are not sure what the website is, so they click the link thinking the software is actually something they can use. Once downloaded, the application becomes installed and starts working. Unfortunately, the software creators of the website did not consider the possibility that a computer could be infected with Ransomware and become a victim of the Eternalblue virus.

What is the motive of the Ransomware attackers? The motivations of attackers vary widely. Some use the opportunity of free software downloads and applications to extract monetary information from users. Other attackers gain access to computers that have been compromised and infected with malware by installing the bitcoin ransomware onto the systems.

How is the encryption used in the Ransomware attack? In most cases, Ransomware attackers will create a working copy of the ” bitcoins” currency, then encrypt it with a highly secure encryption process. The resulting file will be then encrypted using another method. Anyone who wants to try to open or read the file will have no idea what it is because the encryption key is also encrypted.

How are organisations protected from the threats of Ransomware? The best way to prevent organisations from becoming infected with the malware is to implement strong administrative procedures and policy controls to prevent confidential data being passed onto the criminals. This will make it difficult for the criminals to do their dirty work and spread their infection to other computers.

What is the cost to victims of Ransomware? Not only does the encrypted file contain a key for the criminals to get into your computer, but also the information contained within it can be used to drain your bank account, destroy your identity and infect your contacts. The best defence is prevention – make sure you remove all forms of encryption from your computer and don’t download programs or share files online that you’re unsure about. If you’re not sure how to do this, contact your provider and ask them for advice.
