How to Remove .java (Crysis) Ransomware and Recover Your Files

How to decrypt .java files and remove Java virus

What is Java ransomware

If your files have been encrypted, and .id-[your-id].[contact-email].java extension has been added to them, that was the work of the newest variant of Crysis (Dharma) ransomware. That ransomware takes advantage of unsecure RDP setups (a weak password usually) to enter the machine and encrypt all files that might be of any importance to the user/company (by targeting certain file types). Crysis ransmware uses strong encryption method, and so far security researches weren’t able to find vulnerabilities that would allow them to create a decrypter. However, two first versions of Crysis ransomware – .crysis and .dharma – had their master decryption keys anonymously posted on computer security forums, making it possible for antivirus vendors to create decryption tools. Of course, these tools will only work on files encrypted by those two ransomware variants, and won’t work on .java files. At the time of writing no free decrypter for .java ransomware exists, however you can use some other methods of recovering encrypted files. READ MORE

How to Remove Scarab Ransomware and Restore Encrypted Files

How to decrypt .scarab files and remove Scarab virus

What is Scarab ransomware?

This ransomware variant is dubbed Scarab because of the extension it adds to encrypted files; it has been around since at least June this year when it was discovered by a security researcher. Lately Scarab has seen a rapid increase in activity, distributed to users mostly by spam emails with 7Zip archives containing supposed images of scanned documents. Once opened, these “images”, which are really Visual Basic Script files, would download and launch a Scarab ransomware executable. Scarab would scan the computer for most common file types, create encrypted versions of those files and delete the originals. READ MORE

What is Arena ransomware

At least two ransomware variants use .arena extension for encrypted files: Arena from Crysis (Dharma) ransomware family and Arena from CryptoMix family. Crysis’s Arena usually infects computers through Remote Desktop Services (RDP). It encrypts files using strong encryption algorithm that is considered unbreakable and upends .id-[your-id].[contact-email].arena to file names. From the information we gathered, users are asked to pay 0.5 bitcoins in the first 24 hours and 1 bitcoin later. This Arena will launch automatically every time you login to Windows and will encrypt new files that were created since its last run. Crysis’s Arena will create ransom notes called info.hta and FILES ENCRYPTED.txt (with a short text “all your data has been locked us You want to return? write email [contact-email]”).
CryptoMix’s Arena modifies names of encrypted files into hexadecimal strings and upends .arena extension. Its ransom note is named _HELP_INSTRUCTION.TXT.
Unfortunately, both Arena versions don’t have free decrypters as of now. However, you may try some other methods of recovering encrypted files. READ MORE

How to Remove Locky Ransomware

What Is Locky Ransomware?

Locky is ransomware not different from many others: it encrypts user’s files and demands payment for a decryption tool. Files stored in cloud services and shared files on local networks are also encrypted, so the only sure way to get back the files is to restore from offline backups. Even paying the ransom is not a reliable method: some users reported that the decryption tool wasn’t able to decrypt all of the files. However, some methods, like restoring the files from shadow copies, might work in some cases. If you were hit and want to find out how to remove Locky and decrypt your files, you can read this article. READ MORE
