Currently, Darus virus attacks a wide range of computers in various parts of the world. The degree of its distribution and the severity of the infection definitely requires for you to react immediately before Darus turns all your important data into files that cannot be opened.
This article intends to assist you in deleting Darus Virus Ransomware at no cost. Our guide also shows how any Darus file can be restored.
Darus – How bad is it?
Darus can be described as a typical ransomware-type threat.
The term “ransomware” actually means the software that performs some malicious modifications with your files and asks you to pay the ransom to get them back to the initial state. Darus was first discovered by Michael Gillespie1.
The infection originates from the Djvu ransomware family. Darus is not much different from other ransomware samples. So it encrypts all popular file types. As quickly as the certain file is encrypted users are not able to use it. Darus sets the “.darus” extension into each file it encrypts. For instance, the file “my-photo.jpg”, upon being encrypted by Darus, will be changed into “my-photo.jpg.darus”. Upon the encryption completion, Darus generates a specific text file (for example “_readme.txt”) and puts it into every folder where the encrypted information is stored.
The scary notification produced by Darus warning demanding for the ransom to be paid is literally the same as the alerts presented by other ransomware samples that derive from the Djvu family. It basically indicates that the information is encrypted by it and that the just remedy to decrypt it is to apply a one-of-a-kind decryption key (decryptor). It is quite regretful to admit that this is an absolutely true statement.
The variant of the cryptography method implemented by Darus is yet not duly researched. At the same time, it is definitely true that each user whose data got encrypted may be issued a special decryption key, which is definitely a special and there are no other variations of it. It is quite unlikely that users will manage to recover the data without the key in place.
Once Darus is active it is impossible for people to get access to the key, which is located on a remote server controlled by the criminals related to Darus ransomware.
In order to obtain the key and restore the necessary data users are forced to actually pay the ransom, which equals to $980. To get the payment information users are told to get in touch with the criminals by means of sending an email or by telegram.
The warning also states that the victims should contact the Darus representatives within 72 hours beginning from the moment of data encryption. The alert indicates that by contacting within 72 hours people will be given a 50% rebate, thus the ransom figure will be decreased to $490). Nonetheless, no matter what the requested sum is, you should not pay the ransom!
What about paying the Darus ransom?
If you believe that paying the demanded ransom is the just solution, I need to mention a few things peculiar to that option. The crook who is using the Ransomware infection tool certainly wants you to believe that there is truly no other way-out to restore the data.
Definitely, as you might think, the ransom is generally meant to be transferred under certain specific pre-defined regulations and rules. Often this is done by means of Bitcoins as a transfer currency. The application of Bitcoins is often the preferred way by cyber frauds because such transfers are extremely unlikely to get tracked.
Due to this feature of the bitcoins, they are often applied by hackers that intend to scare the targeted users by using ransomware virus. The use of such hard-to-track virtual currency is the key factor why almost all ransomware frauds manage to remain anonymous after successfully completing their covetous fraudulent goals.
Nevertheless, in many cases, even the payment of the demanded ransom might not assist the virus victims as it is quite likely that they may not get any file-decryption data. In events like these, it is very important that the user tries all other available options that might be in place – paying the money is most certainly not the good idea and must not be the main solution.
Online crooks cannot be trusted, they completely don’t care what you feel about the trouble with your data, even when you do pay the ransom. For this reason, paying the amount asked by these frauds does not bring you to the positive resolution of your problem. So, you simply waste your money for absolutely nothing.
I certainly recommend that you do not get in touch with these frauds and do not send money into their pockets. Currently, there are no applications capable of cracking Darus ransomware or restoring the encrypted information at no cost. Hence, the only feasible solution is to restore the lost information from the backup, as long as it is available.
You ought to be aware that the online realm currently is full of infections that look pretty much the same as the Darus virus. Hazardous applications classified as ransomware are generally developed to encrypt crucial files and to express the demand before the victim to eventually transfer the ransom amount into the pockets of the frauds standing behind them.
The feature of all such ransomware infections is that they refer to a similar mechanism for generating the standalone decryption key to decrypt the compromised data.
Hence, unless the ransomware is still under development or has some concealed flaws, manually restoring the data is something you can’t really do. The just remedy to avoid the loss of your important files is to permanently make backups of your important data.
Keep in mind that even if you make such backups, they must be immediately put into a special location not associated with your main workstation.
For example, the backup may be stored on the USB flash drive or some other external hard drive device. Alternatively, you may use the service of online (cloud) data storage.
Of course, when you keep your backup data on your regular system, it might be easily encrypted as well as other documents.
Hence, storing the backup on your main PC is certainly not a reasonable decision.
How does Darus attack the PC?
Darus used different methods to inject its roots into the system. It is not really certain what particular method was used to infiltrate your system.
Darus ransomware attack following a successful phishing attempt.
However, these are the channels through which it may be enabled in your system:
- concealed installation together with other programs, especially the ones promoted on a free basis;
- links to Darus contained in unsolicited spam mail;
- online free hosting services;
- illegal crack downloads from peer-to-peer (P2P) resources.
There were instances when Darus ransomware was introduced as some legit app, for example, in the alerts suggesting to perform some necessary software or browser updates. This is typically how some online crooks aim to convince you into injecting Darus threat manually, through your direct role in the installation procedure.
Of course, the fake update alert will not mention that you are going to install ransomware. This installation will be masked under some claim stating that supposedly you need to update Adobe Flash Player or some other suspicious software.
Needless to mention, the cracked programs are not safe either. It is illegal to download them in the first place, but additionally, they may inject dangerous applications into your system, including Darus ransomware.
So, what can you do to prevent Darus from injecting its malicious roots into your system. In spite of the fact that there is no 100% guarantee to prevent your PC from getting infected. There are some recommendations I want to give you to avoid Darus intrusion. You ought to be careful while installing free applications.
Take time to read what the installers suggest in addition to the main free software. You also need to be careful not to open insecure email attachments. Especially if you are not familiar with the sender. It is very important that your existing anti-infection software is properly updated.
As mentioned, some malicious utilities in the system may perform their dangerous functions in a secret form in your system. I recommend that you scan your system with the proper anti-malware software to identify possible leaks in your system security.
