7ev3n Ransomware

What is 7ev3n Ransomware?

One of the most feared malware infections are most probably Trojan ransomware programs, such as 7ev3n Ransomware. This Trojan is feared for a good reason. According to our malware specialists at Anti-Spyware-101.com, this ransomware can block your computer so that you cannot launch any executables and it encrypts all your major files at the same time, such as project files, databases, documents, and images as well. Letting this malware on board is a virtual suicide because you may easily lose all your precious files if you do not have a backup on an external HDD or flash drive. When it comes to understanding the damage such a Trojan can do to you and your computer, having security backups start to make a lot of sense. If you do not keep such a copy of your files, there is a good chance that you will never use them again when this infection strikes. Reports show that even if you decide to pay the unusually high ransom fee, it cannot be guaranteed that you will actually get the decryption key, i.e., the private key, which is stored on a secret remote server. That is why we believe that you should remove 7ev3n Ransomware immediately because until you do so, you will not be able to use your PC. If you do not clean this infection entirely from your system, there is a chance that it reactivates and it encrypts your new files as well. Please read our full report to be able to fight and win this battle against this malicious Trojan.

Where does 7ev3n Ransomware come from?

As far as research shows, this Trojan may enter your computer in two ways mainly. The most frequent distribution method may be via spam e-mail attachments, such as videos, images, and document files. You need to be vigilant when it comes to opening e-mails. In fact, not only the infected attachments can hold unpleasant surprises for you, but the body of the mail just as well. For example, you may find links or hyper-linked texts in the body, which claim to redirect you to an important page, but, instead, clicking on them will simply drop this Trojan onto your PC. These spam mails may be able to avert your spam filters as well because they may seem to come from well-known companies or even from someone in your contact list as sender. Therefore, you really need to be aware of your clicks and which mails and attachments to open or not; because, one single click may change the fate of your computer and your files stored on it.

Another frequently used method to spread this and other Trojans is through social networking. A lot of computer users are rather careless when it comes to checking out posts on, for example, Twitter and Facebook. That is why cyber criminals like to fool these users into clicking on their infected content. This could be any kind of fake video or image, which are quite often of pornographic nature. It is also possible to download malicious software bundles from questionable file-sharing sites or simply by clicking on infected third-party ads generated by adware infections, which are already on your computer. In any case, it is best to delete 7ev3n Ransomware ASAP and check your system for other potential threats as well.

How does 7ev3n Ransomware work?

Once this dangerous malware infection sneaks onto your computer, it makes sure that it restarts with Windows every time you want to reboot your system. This Trojan uses certain registry key settings in order to do this (e.g., changing HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run|System). It also makes sure that you cannot launch any executables, i.e., programs. Our researchers say that this infection ends the explorer.exe process as well, which is practically the main process of the operating system. While this malware is active on your computer, it can slow down the performance. Once it is done with the preparations, it encrypts the targeted files: .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .jpg, .png, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml, .psd, .java, .jpeg, .pptm, .pptx, .xlsb, .xlsm, .db, .docm, .sql, .pdf. As you can see, it mainly targets important files such as project files, documents, and images so that you would really miss these and you would be ready to pay for them.

Once the encryption is done, this Trojan ransomware displays its warning message on your desktop, above everything else so that you definitely see it. This message informs you about a number of things, for example, that your personal files have been encrypted and you have 96 hour to pay the ransom. You can also find some information about Bitcoin itself, which is the most often used payment method for ransomware, such as where you can buy Bitcoin in the first place (ebay.com, localbitcoins.com, anxpro.com, and ccedk.com). The criminals behind this Trojan seem to be rather greedy as they are asking for 13BTC (about $5100) for the private key. The usual amount is around 1BTC, so we can say that this is a rather steep price to pay. We do not think that any common computer users could pay this much; therefore, it is quite possible that this ransomware is mainly aimed at companies.
