How does ransomware spread

There are various ways you could have picked up the threat. While it’s more likely you infected your device via a basic method, ransomware also uses more sophisticated ones. Many ransomware creators/distributors stick to sending emails with the infection attached and hosting the malware on different download websites, as those methods don’t require much skill. Infecting a computer via contaminated email attachments is perhaps most common. Crooks have large databases with potential victim email addresses, and all they have to do is write a semi-convincing email and attach the ransomware file to it. Typically, the email wouldn’t convince those who have experience in these matters, but if you have never come across it before, you opening it wouldn’t be that shocking. If you pay sufficient attention, you would notice particular signs that make it obvious, such as the sender having a random email address, or countless mistakes in the text. People tend to drop their guard if they know the sender, so you might encounter criminals feigning to be from some known company like Amazon. So, for example, if Amazon emails you, you still have to check if the email address is right just be sure. You should also take note of whether your name was used somewhere in the email, the greeting in particular. Senders who say to have some kind of business with you would not include common greetings like User, Customer, Sir/Madam, as they would know your name. As an example, if you are an eBay user, the name you’ve given them will be automatically inserted into any email you are sent.

In short, make sure that the sender is legitimate before you rush to open the file attached. And if you are on a dubious web page, do not press on advertisements or engage in what they propose. If you aren’t cautious, ransomware might be permitted to get into your device. It is best to ignore those ads, no matter how appealing they might be, because they’re hardly trustworthy. And stop jeopardizing your machine by using download dangerous download sources. If you’re frequently using torrents, at least make sure to read people’s comments before downloading one. In other cases, vulnerabilities in programs may be employed by the ransomware to enter. That is why keeping your programs updated is important. Whenever a patch is released, install it.

What happened to your files

Soon after the infected file is opened, your device will be scanned by the ransomware to locate specific file types. All files that may be valuable to you, such as photos, documents, etc, will be targets. The file-encrypting malware will use a powerful encryption algorithm for file encryption once they’ve been found. The encrypted files will have a weird extension attached to them, so you’ll easily see which ones have been locked. If you are still uncertain about what happened, a ransom message will explain the situation and request that you buy a decryptor. Depending on the ransomware, the decryptor could cost $100 or a even up to $1000. It is up to you whether you want to pay the ransom, but do consider why this option isn’t advised. You could have other means to recover files, thus you ought to research them before you make any decisions. Maybe a decryption program has been released for free by malicious software specialists. You might have also backed up your files somewhere but not recall it. You could also try file recovery via Shadow Explorer, the ransomware may have not removed the copies of your files known as Shadow copies. We hope you have gotten backup and will start backing up your files routinely, so that you do not risk losing your files again. In case backup is an option, first eliminate .Bigdata extension virus and only then go to file recovery.
