Ransomware spread methods

If you do not know how the ransomware could have slipped into your machine or what you can do to prevent such threats in the future, study this section of the report in detail. Commonly, ransomware stick to rather basic methods in order to infect a computer, but it is also possible infection occurred through more elaborate ones. Sending spam emails and hosting their malicious software on different download platforms are what we mean when we say simple, as it does not need much skill, thus popular among low-level cyber criminals. Via spam is possibly how the threat managed to enter. The file contaminated with ransomware is attached to a kind of authentic email, and sent to possible victims, whose email addresses criminals were given by other criminals. Generally, those emails have hints of being bogus, but if you have never run into them before, it might not be so. Be on the lookout for particular signs that you’re dealing with malware, something like a nonsensical email addresses and a lot of grammar mistakes in the text. Crooks also like to use popular company names to put people at ease. So, as an example, if Amazon emails you, you still need to check whether the email address really belongs to the company. If your name isn’t mentioned in the email, for example, in the greeting, that should raise doubt. Senders who say to have some kind of business with you wouldn’t include general greetings like User, Customer, Sir/Madam, as they would know your name. So if you’ve used eBay before, and they email you about something, you will be addressed with the name you’ve given them, and not as Member, etc.

If you have just skipped the entire section, just keep in mind that checking the sender’s identity before opening the attached file is crucial. You need to also be careful and not click on ads when visiting websites with a questionable reputation. If you engage with a malicious advertisement, some kind of malware might download. Advertisements hosted on dubious web pages are rarely trustworthy, so do not interact with them. And stop using download sources that could easily be harmful. If you’re doing downloads through torrents, you should always check if the torrent is safe by checking other users’s comments. Software vulnerabilities can also be used for malicious software to enter. In order for those flaws to not be exploited, you have to keep your software up-to-date. When software vendors become aware of a flaw, they it’s fixed in an update, and all you really need to do is install the fix.

What happened to your files

As soon as the ransomware file is opened, the will scan your computer and encode certain files. Its prime targets are documents and media files, as they likely will be valuable to you. The ransomware will use a powerful encryption algorithm for data encryption once they have been discovered. A strange file extension added will help find out which files were locked. You should then see a ransom note, with info about what happened to your files and how much you must pay to get a  decryptor. You could be requested a couple of thousands of dollars, or just $20, it all depends on the ransomware. While the choice is yours to make, do consider why this choice is not recommended. It is possible you can accomplish data recovery via other ways, so research them before anything else. If it’s possible for the ransomware to be cracked, it’s possible malware analysts have developed a free decryption program. It is also possible you do have backup available, you might simply not realize it. It may also be possible that the Shadow copies of your files were not removed, which means they’re recoverable through Shadow Explorer. We hope you have obtained backup and will start backing up your files routinely, so that this situation doesn’t happen again. However, if you had backed up files prior to the infection taking place, file recover should be carried out after you terminate .Gusau file virus.
