Distribution Technique
Dutan Ransomware – New strain of DJVU ransomware family. Alike its cousins, it
propagates via the most famous gateway i.e. spam campaigns. Under such attacks,
an e-mail is sent, with a word document or PDF attachment. It looks legitimate
however, the danger lies deep within the content/attachment. Once opened on the
targeted system, the files trigger the macros of .dutan. At times, instead of
attachments, a hyperlink is provided within the content of e-mail. Once clicked,
they might lead you to certain questionable websites.
Users, have you heard about Trojans? This malicious program is designed by
cyber criminals to carry out malicious activities. Once it makes it backdoor entry, it
opens gateways for other malicious payloads.

of proper knowledge and reckless behavior. Hence, install a good antivirus in your
system & scan on regular basis.

Threat Behavior
The moment, Dutan virus infiltrates your system, it begins the malicious activities.
Typically, .dutan file extension blocks the access to your files encrypting them. It
gains the access of your system through the malicious file attachments in spam emails. Once, it infiltrates the system, it appends ‘.dutan’ extension to the encrypted
filenames. For example, ‘Apple.jpeg’ will be renamed as ‘Apple.jpeg.dutan’. The
encryption algorithm used by this malicious program is strong and generates a
unique decryption key for every .dutan file. This key is stored on the server of
Dutan ransomware developers. After successful file encryption, you can no longer
open/read your files. For Dutan data recovery, you are bound to purchase the
decryption key by the hackers. Simultaneously, this devastating software creates a
ransom note file named - ‘_readme.txt’. Every time you try to open your virus
encrypted files, the created ransom – demanding note will be displayed on your
screen. The ransom note provides a link which enables you to download the
decryption tool.
_readme.txt:
As mentioned earlier, the powerful algorithm makes it next to impossible to
decrypt all files manually. Decryption tool or key is what you will need for data
recovery. However, getting the decryption key is not an easy task! Stored on
hacker’s serve, it is only exchanged for large amount of ransom.
If you do not want to get trapped in such scams, focus on the steps to remove
Dutan ransomware from your system. Undoubtedly, it is a challenging task without
the key. However not impossible!
