What is Ofww Ransomware

Developed by the Djvu family, Ofww Ransomware is a malicious program that runs extensive encryption of personal data. It uses popular, yet strong algorithms to put the stored files under severe lock. This, therefore, prevents users from succeeding in manual decryption. Knowing that users will not be able to recover files on their own, cybercriminals offer to decrypt data using their tools for a certain amount of money. The details that are presented inside a text note called _readme.txt, which is created after Ofww assigns new extensions to data. Specifically, it adds the .ofww extension so that encrypted files would look something like this 1.pdf.ofww. As soon as such changes are done, users will be no longer eligible to access their data.

Developers behind the Djvu family have published a lot of ransomware versions thus far (e.g. Sspq, Paas, Ehiz, Nusm, Pcqq, etc.). Yet all of them contain the same information inside of ransom notes. Cybercriminals say that data like pictures, documents, databases, and other kinds of intel have been strongly encrypted. To return access to them, users are offered to buy the decryption software, as there is no other way to unlock it for free. The cost of such software is $980, however, there is an option to drop the price 50%-off in case you contact the swindlers within 72 hours. Besides that, it is also proposed to test free decryption. For this, victims are required to send max. 1 file that does not contain valuable information to their e-mail address (admin@helpdata.top or supportsys@airmail.cc). Even though they will decrypt one file indeed, there are doubts about their trustworthiness still. Most cybercriminals tend to fool their victims and not send any decryption tools even after receiving the ransom. This is why the best and only way to recover your data yourself is using the latest backup copies that were created and stored on external devices prior to the infection. You can try to use third-party tools as well, but there is little chance they will decrypt your data. Moreover, using third-party utilities other than those offered by cyber criminals might lead to permanent data loss. Ransomware developers install certain entries that help them detect a third-party presence. Whatever the case, it is important to delete Ofww Ransomware to prevent further encryption and infiltration of other networks. All information on that can be found in the article below.

How Ofww Ransomware infected your computer

It is quite common for ransomware infections to exploit various distribution channels to reach their victims. This list is pretty broad and includes e-mail spam messages with malicious attachments, trojans, fake software cracking tools, unprotected RDP configuration, backdoors, keyloggers, untrustworthy downloads, fake software updates, unreliable torrents trackers, malicious ads, and so forth. E-mail spam messages are fabricated letters sent by ostensibly legitimate campaigns with malicious attachments. Cybercriminals insert files with .docx, .pdf, .js, .exe, and other files making the infection less suspicious. It is also likely to see a link leading to dubious websites that promote malware via fake or unwanted software. Once users end up tricked into interacting with such content, they become at risk of being struck with malicious software. Another popular method abused by ransomware developers is trojans. It is a type of malware causing chains infections. They get installed on your system and download additional malware from the server of cybercriminals. Usually, they can be hidden inside fake software crackers, updates, and other suspicious kinds of software. The only way to fully evade these types of infections downloading only trusted and legitimate software. Of course, you can increase your protection with the help of anti-malware software, but it is still important to be more careful whilst surfing around the web.
