Guide to Remove Darus Ransomware
Darus Ransomware is another menacing member in the arsenal of the infamous
Stop Djvu Ransomware family. Just like other siblings, Darus has been generated
with strong financial motive. It spreads its infection mostly via spam e-mail
campaigns & unreliable software download sources.
Once the system is infected, it looks for the targeted user & system files as such
documents, image files, video files & audio files. When found, it encrypts them by
adding a malign Darus extension to the filenames, hence making them inaccessible
to the victims.
One can understand the infuriation & agitation caused to the victims by .Darus file
virus & its siblings such Horon, Gehad, Madek, Godes, Dutan & the list goes on…

Threat Behavior of Darus Ransomware Alike its siblings, Darus Ransomware has been developed to generate illicit
revenue by extorting ransom from the victims of .Darus file virus.
The attack of Darus begins with common internet services. Some of the spread
channels employed by the hackers include spam e-mail campaigns, unreliable
software download sources, torrent websites & fraudulent online advertising.
Upon entering the system, Darus scans the infected system for targeted user &
system files. When found, it encrypts them with RAS (Rivest–Shamir–Adleman)
& AES (Advanced Encryption Standard) Encryption methods. These
cryptographies are highly-complex. They also generate a unique private decryption
key for each infected user & store them on the hacker-controlled server.
The encrypted files are renamed with .Darus extension & hence, instantly made
unusable to the victims.
A file “image.jpg” might be renamed as “image.jpg.darus” after the encryption.
The file extensions that are at the target of the Darus Ransomware include:
 Document files (.docx, .doc, .odt, .rtf, .text, .pdf, .htm, .ppt)
 Audio Files (.mp3, .aif, .iff, .m3u, .m4u, .mid, .mpa, .wma, .ra, .avi,
.mov, .mp4)
 Video Files (.3gp, .mpeg, .3g2, .asf, .asx, .flv, .mpg, .wmv, .vob)
 Images (.jpg, .jpeg, .raw, .tif, .gif, .png)
 Backup Files (.bck, .bckp, .tmp, .gho)
Insight into the Ransom Note & Amount Demanded by Hackers
Following the successful encryption, it drops a ransom-demanding message in
every folder than contains Darus infected files. This ransom note is in text format
& named “_readme.txt”.
The ransom note appears every time a victim tries to access the encrypted file. It
contains the present situation of the system & certain instructions to the victims.
The note conveys that decryption of data is not possible without hacker’s
interference. The restoration of data requires a unique private key & Darus
decrypter that is stored on the hacker’s server.
To purchase the Darus decryption tool & key, the victim must contact the hackers
on their e-mail - [email protected] & [email protected]. In addition
to that, victims must pay a ransom of $980 in bitcoins.
It suggests that the victims reaching out to hackers within 72 hours of the
encryption, will be given 50% in the ransom amount i.e., $480 (in bitcoins).
Fake Claims by Hackers
In order to guarantee the decryption, hackers ask victims to send them one file first
via e-mail. The file should not contain any valuable information, the note says.
The file will be decrypted for absolutely no cost & sent back to the victims.
Fearing to lose their sensitive data, may victims contact the hackers & send them a
file to decrypt.
However, please note that these claims are false. The research has revealed that
victims often stop receiving response from the hackers after receiving the ransom
amount.
Therefore, instead of panicking & contacting the hackers, the victims should act
smart & do not let the hackers extort money from them.

Distribution Techniques of Darus Ransomware –
Sources state that Darus is spreading its infection through various distribution
channels at an alarming rate. No wonder why Djvu Ransomware family is
considered as the most wide-spread malware infection.
The most prevalent spread method employed by the hackers is Spam E-mail
Campaigns.
Users often tend to click on the e-mail with luring subject lines without discerning
that content in the e-mail may be malicious. The hackers take the leverage of this
careless attitude of computer users.
Hackers send out colossal amount of e-mails containing infected links &
attachments. They suggest the receiver about an undelivered shipment from legit
shipping services like DHL & FedEx.
A mere click on these attachments, links & files installs Darus Ransomware on the
system.
