Just imagine that when you wake up in the morning and turn on your laptop and find that every photo, video, song or video in the box is incomprehensible. That’s just a $ 400 message on the screen to restore the files.
Thousands of people have experienced this over the past decade. According to the 2017 FBI Crime Report, 2.4 million USDollars (approximately Rs. 427 million) extorted. According to a survey by Google, Ransomware has accounted for about USD 25 million in the last two years. In this article you will learn how to protect PC from Ransomware.
Ransomware comes from the words Ransom + Malware. Ransom in English is the word for Ransom. The term ransomware refers to Malware, which designed to ransom. Ransomware is a ransom to grab data on a PC and release it. This ransomware comes into the PC with an email attachment, or a web link, run malicious code and take over the PC. There are two main types of ransomware.
1. Blocker Ransomware
Blocker Basic functionalities blocked on the PC. For example, they can display a software interface designed to ransom the PC directly. Besides, the PC cannot use to do any work. But better not to block our file encrypt from Blocker Ransomware. That means there is little chance of data loss.
2. Crypto Ransomware
This is the worst. Crypto ransomware encrypts all the other documents, photos, videos, and audios without any harm to the PC’s basic functionality. After this ransomware is affected, the PC will give you a 24 hour / 36-hour countdown to pay the ransom. If you can’t pay on time, everything encrypted will deleted. Some ransom has reportedly ransomed from $ 200-300 to $ 10000-15,000.
These include ads/pop-ups that claim that there is additional virus/malware and that the PC has faults and that Fake Messages charges some amount to fix them.
Here are some of the worst ransomware of 2017
1. Petya – This ransomware is directly attacked by encrypting the boot section of the OS and file management. As such, the OS is unable to boot or access the file.
2. Bad Rabbit – It is extended through a Fake Adobe Flash Installer. When Affect, the password will be guessed at every network connected to the PC. In addition to the files, it also encrypts the Master Boot Record with data related to the OS boot. A dark web link is provided through the Tor Browser to pay the ransom.
3. Wannacry – Ransomware is one of the fastest spreading worldwide. The UK and Russian government networks were also attacked. It reports that Bitcoin has to pay the ransom.
How To rebuild A PC With affected from Ransomware
Whether or not you can eliminate Ransomware depends on several factors. If the PC comes to the ransom screen without booting to Windows, it is a blocker. There is less chance of encrypting files. All you have to do is boot a Rescue Disk Pen, login to it, copy the file to an external drive, scan the Rescue Disk, and run the Ransomware.
Crypto Ransomware saves the basics of the OS. That means Windows will boot. But all our files are encrypted. Here we need to disable the Ransomware Exe. You can use software like Hitman Pro to scan and remove the ransomware. But it can’t restore the encrypted data. Before you scan your software, the ransom note / key file that describes the ransomware stored on the desktop as a Txt / HTML file. Could you not delete it like a pen drive? This ransom note/key data is essential when decrypting files.
How to decrypt that encrypted files
Now let’s see how we can decrypt our encrypted files on a decryptor. Security researchers around the world have breached this encryption. First, let’s find out what ransomware we’ve got and how we can decrypt it.
- Give the PC an internet connection and go to a site called id-ransomware.malwarehunterteam.com.
- There are two options: Ransom Note and Sample Encrypted File under Upload Files.
- You can browse a ransom note in the affected ransomware or an encrypted file and click the upload button.
- If you can decrypt the Ransomware, then “This Ransomware is Decryptable!” You can decrypt your file under More Info and download a Decryptor free download.
- But if you can’t decrypt the ransomware, then a message page will say, “This Ransomware has no known way of decrypting files, and hope for a solution in the future.” If it is, you son, if you have a backup, you can remove the ransom and restore it. But otherwise, the data is so worth it that you have to store the important encrypted data, the ransom note, and the encryption key somewhere. It can do in two weeks, maybe two in a year.
- Click on it like you would like to notify and click here. Then you can give the email a form and email it to confirm. Then you will know about the ransomware updates.
Or what’s left is to pay the ransom. But there have been numerous cases where the data has not been paid again. Because if you have money greed, you may want to pay the ransom. Data is so valuable that you have to pay for it by asking for a demo-decryption.
How can a ransomware minimize the damage?
- Use a good Virus guard firewall.
- Use Trusted Websites.
- Keep the OS up-to-date.
- Backup important data securely.
- Fake pop-ups, Fake Download links should alert if their PC is using more cruelty. Also, create a separate user account with no administrative access.
