Oscar Venom ransomware is a virus that offers to view ransom note in a few different languages
Oscar Venom ransomware is a file locking malware that threatens to destroy decryption key within 24 hours of the infection.
Oscar Venom ransomware is a file locking malware that was first spotted in mid-January 2019. It is a variant of the Jigsaw ransomware – a relatively old cyber threat, although hackers are still developing new versions. It encrypts data with the help of AES cipher and then drops a ransom-demanding note /Your files have been encrypted\ that can be viewed in English, German, Turkish and Arabic. All the data is marked with the .venom file extension and becomes unusable. To recover the access to databases, documents, music, photos, and other files, victims need to pay ransom to Oscar Venom virus authors in Bitcoin cryptocurrency. According to hackers, users only have 24 hours to pay ransom before the decryption tool will become unavailable and personal files lost forever.

Oscar Venom ransomware distribution methods are unknown, however, it most likely uses typical techniques, such as:
- Spam emails;
- Brute-force attacks;
- Fake updates;
- Obfuscated executables;
Oscar Venom virus does not immediately starts file encryption. Before that, it performs several changes to the system, such as Windows registry modification, the addition of scheduled tasks, spawning of additional processes, removing the Shadow Volume copies, and similar. These changes are performed in order to increase persistence and, in some cases, to intervene with Oscar Venom ransomware removal.

Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
