What is Ransomware?
You might have heard the word "ransomware" in the news and wondered what it means. Ransomware is a type of malicious software, or malware, that restricts access to your computer system until you pay a ransom fee.
Ransomware can be spread by e-mail or with infected websites that are set up by cybercriminals. If ransomware infects your computer, it can prevent you from using your files until you pay a ransom fee. This type of malware also restricts access to other types of content on your computer such as music and movies so if you try to use those items, they may not work unless the ransom has been paid.
The problem with paying these fees is that the cybercriminals may not give you the decryption key when you pay them so you may not be able to access your files. Sometimes, paying the fee doesn't even guarantee that your files will be returned since cybercriminals have ways to steal money and identities without returning those items.
How Does Ransomware Spread?
It can spread through e-mail and websites, like a Trojan or viruses do with traditional malware. People can also become infected when they visit ransomware websites that have been set up by cybercriminals.
If ransomware is executed, it can change the Registry to make sure that it starts when the computer starts. It can also be called by other malicious software that is already on your computer.
How Does Cryt0y Ransomware Work?
Cryt0y Ransomware encrypts your files and then informs you that the key is only available for the ransom price. Cryt0y Ransomware also encrypts your personal files, including system files, and renders them useless unless a decryption key is obtained. Cryt0y Ransomware restricts access to some of your software by preventing it from starting up unless a ransom is paid. Cryt0y Ransomware changes the Registry to make it start automatically when Windows starts. Cryt0y Ransomware makes sure that other malware processes (malicious software like viruses) are running when Windows starts in order to use the computer.
Cryt0y Ransomware encrypts your files with an RSA and AES encryption algorithm. After the data has been encrypted, Cryt0y Ransomware will create a HTML file with instructions in it on how to pay the ransom. The HTML file is called "info.html", which is hidden within your %Temp% folder so you won't find it by browsing through Windows Explorer. Another file, "recover_my_files.html" will be located within your %Temp% folder. This file contains a link to where you can download the decryption program.
Cryt0y Ransomware also changes your desktop background to a black image that says "html decryptor" and it places a shortcut on your desktop that links back to the HTML decryptor site. You are instructed to download the HTML decryptor so that you can decrypt your files for free.
How to Remove Cryt0y Ransomware
Cryt0y Ransomware is a type of malicious software called ransomware. It can encrypt your files and restrict access to them until you pay a ransom fee. If the ransom has not been paid, then Cryt0y Ransomware will use your computer system's resources such as processing power and data storage to do the work for other criminals. This means that Cryt0y Ransomware will make Windows work harder, which can cause it to overheat or freeze up.
It's possible to remove Cryt0y Ransomware without paying the ransom fee by taking these steps:
1. First of all, make sure you have backups of your important files. Backing up your data will ensure that you will never lose important documents in the case that Cryt0y Ransomware does not allow access to your computer files again. If you have already made backups of all your important files, then follow the next step.
2. Download and run an anti-malware program and make sure to update it before scanning your computer for malicious software such as Cryt0y Ransomware.
3. If you successfully remove Cryt0y Ransomware through the steps above, then you can reset your Windows hosts file by following these instructions:
Click Start > Control Panel > System and Security > Administrative Tools > Services. Right-click on the "Windows Hosts" service and select "Properties". In the "General" tab, click "Startup type". Select "Automatic". Click "OK". Restart your computer.
There is a possibility that by following the steps above your computer will be compromised, so you should use additional protection methods such as using an antivirus that is updated and trusted by other users.
How to Protect My Computer From Ransomware
1. Back up your important files to avoid them being locked by ransomware. Restore your files from the backups if you are infected with ransomware that encrypts your files, or doesn't give you the key to unlock them.
2. Use reputable antivirus software that is updated and trusted by other users, and always keep it up-to-date with new security patches and definitions.
3. Be aware of clicking on unknown links when browsing in order to avoid visiting malicious websites set up by cybercriminals which can lead to malware such as Cryt0y Ransomware being downloaded onto your computer without knowing it.
4. Be careful when opening emails from unknown senders and avoid opening attachments unless you know for sure that it is safe to do so.
5. Create strong passwords that have letters, numbers and symbols, and make sure to not use any words or names within them so that they are hard for other people to guess. Strong passwords will deter many cybercriminals from trying to break into your computer
