ROOE ransomware hits victims worldwide
ROOE ransomware is the 206th version of DJVU malware which is designed to encrypt all files on victim’s computer, making it impossible to open them. Once installed, it scans the system for photos, documents, videos and other data formats, encrypts them, and appends .rooe extensions to them. Then the ransomware creates a ransom note called _readme.txt and leaves it on desktop and other affected file folders. According to the note, the victim needs to pay the attackers a specified sum of money in order to recover the files. The only contact details left are two emails: firstname.lastname@example.org and email@example.com.
ROOE ransomware, sharing a similar name as a previous variant – ROTE ransomware, employs an extremely secure encryption method. There is no way to break or figure out the encryption algorithm. Doing so, even with the strongest computers could take years. Therefore, the criminals suggest buying a decryption software + key in the _readme.txt file. The price for the tools is $490 in Bitcoin, rising to $980 if paid later than 3 days after the initial attack.
The ransomware encryption: explained
ROOE file virus is designed to terminate security software and infiltrate the computer system silently. Once installed, it tries connecting to its Command&Control server, which provides ONLINE encryption keys for each victim individually. However, in some cases the ransomware fails to connect to its server. In such case, the malware uses an in-built encryption key.
ROOE ransomware attacks using either ONLINE, or OFFLINE encryption keys. Knowing about these keys can help you realize you chances to recover data.Norbert Webb
To put it differently, it means that all victims affected by the offline encryption have hope to recover their files as soon as someone (also affected by the offline key) pays the ransom. This is because the key for everyone, as well as the decryption key, are identical. An indicator of offline encryption is t1 at the end of the ID located in C://SystemID/PersonalID.txt file.
If you’re a victim of the offline encryption, follow updates on this DJVU decryption guide.
This cannot be said about victims of the online encryption. Since each victim receives an unique encryption key, ROOE decryption keys also differ. In such situation, there are no free ways to recover files except having data backups.
ROOE ransomware is currently the latest version of the known ransomware, following the BBOO variant. There are no significant differences between DJVU malware variants, except the file marker used and sometimes email addresses left to contact the cyber criminals.
Victims of ROOE file virus should be aware of the fact that their computer systems are most likely infected with AZORULT password-stealing malware, which is known to spread alongside DJVU variants. Therefore, an immediate elimination of both the ransomware and the Trojan should be executed as soon as possible.
To remove ROOE ransomware safely, we recommend starting your PC in Safe Mode with Networking, then updating your antivirus and running a full system scan immediately. You can find step-by-step instructions at the end of this post.
|Name||ROOE file virus|
|Origins||STOP/DJVU (206th version)|
|Behavior||Locks victim’s personal file using cryptographic algorithms, then asks paying a ransom in exchange for the data recovery tool|
|File extension||Marks files with .rooe extension|
|Distribution||Distributed via software cracks, keygens, KMSPico|
|Decryption tools||STOP Decryptor currently doesn’t support the 206th ransomware version|
|Removal||Remove using antivirus while in Safe Mode with Networking (use instructions given below)|
Ransomware distribution relies on irresponsible victims’ actions
ROOE ransomware can be found in various downloads available online. Security researchers have noticed the virus’ developers’ tendency to put the malicious payload into various software cracks, keygens, illegal and copyrighted content, tools like KMSPico and others. In other words, if you’re trying to access paid content for free, you might run into a STOP/DJVU payload without even expecting it.
While most other ransomware variants rely on malicious spam exclusively, the discussed ransomware creators don’t use such tactic at all. It probably means that the victims’ interest in illegal content is high enough and the attackers do not even need to enroll new distribution vectors to increase the attack scope.
We strongly recommend you to be extremely cautious while browsing the Internet. One irresponsible click can result in a redirect to a malicious website or a life-changing download. Therefore, if you do not want all of your life’s work or memories encrypted, stay away from suspicious websites as far as you can.
Quick way to remove ROOE ransomware virus
One of the best ways to remove ROOE ransomware virus is running an antivirus product. However, make sure you use a trustworthy one and not an infamous product such as Segurazo. Only a robust and up-to-date antivirus will help you to eliminate the ransomware together with Azorult Trojan at once.
ROOE ransomware removal isn’t a complicated task when you’re know what you’re doing. This is why we prepared easy-to-follow guidelines for you to follow. You can find them down below.
