Derp ransomware (Virus Removal Instructions) - Improved Guide

What is Derp ransomware?

Derp ransomware – the 176th version of the Djvu ransomware that is currently undecryptable

Derp virus is ransomware that might delete the hosts file to prevent users from entering security networks

Derp ransomware, discovered by Michael Gillespie,^[1] is one of the latest variants of the Djvu ransomware family that promotes file decryption by using a unique algorithm. Emsisoft reported^[2] that they have released the STOP/Djvu decryption software that works for Djvu ransomware variants that have been released earlier than August 2019, so Derp virus still remains undecryptable as it uses a different decryption tool than its previous ancestors that were released before August. However, the activity principle is the same – alterings of the Windows Registry/Task Manager, encryption by adding a specific appendix (.derp in this case), ransom demands from $490 to $980 via the _readme.txt message.

During installation, Derp ransomware will supposedly drop a malicious executable in the %LocalAppData% or %AppData% folder that is responsible for finding decryptable files on your Windows computer. Additionally, the malware can delete the Windows hosts file to prevent the user from accessing security-related forums and networks.

Nevertheless, you will supposedly find malicious entries and files in the Task Manager and Windows Registry added by Derp ransomware. This way the malware ensures that it will be automatically booted within every computer startup process. Additionally, some dropped entries might allow the malware to avoid being detected by security software.

Derp ransomware is the 176th version released by Djvu virus developers Furthermore, Derp ransomware might target Shadow Copies of the encrypted tada in order to harden the decryption process for the users themselves. For this purpose, the malware launches a module that runs specific PowerShell commands and permanently deletes the Shadow Volume Copies from the computer system.

If you have taken a good look to the _readme.txt ransom note, you will see that Derp ransomware developers are trying to threaten you that there is no other option of recovering your files instead of paying the demanded price:

The criminals urge for $490 if the ransom price is transferred in a three-day time period. However, if the victim is too late and decides to pay after 72 hours, he has to now transfer a doubled price. Derp ransomware urges a pretty big price here and our experts say that it is not worth paying such amount of money while there is a big risk of scamming.

The crooks also provide gorentos@bitmessage.ch, gorentoshelp@firemail.cc email addresses as a way to contact them. We suggest avoiding any contact possible and going straight for Derp ransomware removal. If you get scammed, it would be almost impossible to recover your money as hackers often urge prices in Bitcoin or another cryptocurrency that guarantees full anonymity.

Derp malware is a ransomware virus that urges for $490 if the victim transfers the money in 3 days One more reason why you should remove Derp ransomware ASAP is that the malware can distribute the AZORult Trojan horse.

After Derp ransomware is gone, you can try fixing the damage with software such as FortectIntego. However, note that the tool does not decrypt data. For that, travel to the end of the article and choose a method to try. Also, you can purchase DrWeb's Rescue Pack for $150 that includes decryption software that might be capable of recovering some data and also two full years of antimalware protection.

Vulnerable RDP configuration allows malware installation

Security experts from LosVirus.es^[3] state that RDPs which include weak passwords or no password security at all are a very nice target for bad actors. These people hack the RDP^[4] (for example, TCP port 3389) and connect to the targeted computer system by remote technique.

Even though this ransomware distribution method is a very popular one, there are other techniques that are not less popular. Criminals often drop questionable email messages to the user's inbox or spam sections. Sometimes, the crooks pretend to be from official shipping companies such as FedEx/DHL, banking firms, or healthcare organizations in order to give the look of a trustworthy email.

Afterward, users are encouraged to click on a particular hyperlink or open an infectious attachment where ransomware is hiding. Nevertheless, this still is not it. Hackers are capable of distributing malware via many other different sources! Unsecured p2p networks, outdated software, exploit kits, fake Flash Player updates, infectious downloading links and ads, gambling networks, porn sources – all these places are potential ransomware holders.

Avoiding ransomware and preventing system damage

Continuously, learn how to manage your email box. Delete all messages that fall to your spam section but also be careful with letters that appear in the inbox. Evaluate the expectancy of the email, check out the sender, and search the entire content for grammar/style mistakes. If you have a questionable feeling of the email, better delete it as any reputable company would manage to contact you in other ways, e.g. mobile phone.

Furthermore, avoid downloading movies and video clips from sources such as The Pirate Bay, eMule, and other torrenting networks as these websites provide software cracks that might be filled with dangerous viruses, including ransomware. Also, do not perform any software updates you are not aware of, keep all of your programs regularly upgraded, and keep a fair distance from all questionable online sources.
