What is Oodt Ransomware

Oodt Ransomware runs encryption of data (with RSA 2048 + Salsa20 algorithms), renames filenames with the .oodt extension, and demands money for its return. These traits make it categorized as a ransomware infection. It is also part of a very popular and dangerous ransomware family called STOP/Djvu which is responsible for hundreds of devastating infections. Once Oodt installs onto a system, users will lose access to files they used to open prior to the infection. This is how an infected file will look after successful encryption – from healthy 1.pdf to encrypted 1.pdf.oodt. As soon as the process is done, Oodt unveils ransom instructions inside of text note (_readme.txt). Developers use the same template they did with other ransomware variants originating from the STOP/Djvu family.

It is stated that victims should spend their money on special decryption software held by cybercriminals. The price to be paid is $980, though, it can be cut down to $490 if victims decide to pay within the first 72 hours upon getting infected. To prove malware developers can be trusted, they offer the so-called guarantee, which implies users are allowed to send 1 file (not important) and get it decrypted for free. All the communication related to paying and other details should be established by writing a message to one of the attached e-mail addresses (support@bestyourmail.ch or datarestorehelp@airmail.cc). Unfortunately, getting in touch with swindlers and meeting their requests is not the safest way to recover your data. Many cyber crooks were spotted to fool their victims by not sending any decryption tools after the ransom was paid. Data affected by many ransomware infections including Oodt cannot be decrypted without cybercriminals unless there are serious flaws or bugs that open a window for third-party tools to step in and help. You can also decrypt your data only if ransomware failed to connect to its server in time and used offline keys to restrict data eventually. All offline keys are IDs, ending with t1 characters at the end. Information about what keys have been used can be found inside a text file named PersonalID.txt which is created by the virus as well. In case there are no keys ending with t1, this means they are stored online and can be decrypted only partially or cannot be decrypted at all. Additionally, Oodt Ransomware is known to block popular security websites by modifying Windows HOSTS. while trying to open them in a browser, victims may fail and stumble over the DNS_PROBE_FINISHED_NXDOMAIN error code. The virus can also bring two trojan infections (Azorult or Vidar) which are meant to steal personal information from the victim’s PC. Based on these facts, it is mandatory to remove Oodt Ransomware from your system and avoid having business with its creators. Better restore your data using backup copies or try to use reputable third-party software to decrypt or recover the files. To learn more about removal and recovery methods, follow our tutorial below.

How Oodt Ransomware infected your computer

File-encryptors as well as other infections can be spread via fake torrent downloads of popular software, license cracking tools, unprotected RDP configuration, trojans, malicious e-mail spam attachments, and various other vectors like that. Many users report getting infected after downloading some software from third-party pages or files attached to e-mail spam letters. Such letters are usually presented as something legitimate from popular firms like DHL, DPD, FedEx, eBay, Amazon, and other world-famous giants. Many inexperienced users recognize their names and trust everything written inside a message. As a result, they open malicious files disguised as Word, Excel, PDF, Executable, or JavaScript formats that store direct infection or trojan which will install it. Developers of such letters urge users to download and open them up by saying it is necessary to check the “Status of Parcel” or access “Tracking information”. Other headlines like “Invoices” or “Urgent” can be used to bait potential victims as well. Although users did not order anything from the web to expect such messages, they still venture to follow the requests due to overwhelming curiosity. It is obvious that good protection against malware threats lies in careful online activity. Do not download software from unreliable resources or pages you see the first time in your life. Also, it is advised to keep your head on a swivel whenever it happens to receive suspicious messages claiming to do something. Stay on high alert and do not trust content like that.
