How to remove .java file extension ransomware

.java ransomware is a malicious program that corrupts files on the computer

.java ransomware is a file-encrypting virus that uses AES cryptography.^[1] It belongs to Dharma/Crysis ransomware family and continues attacking computer users from malicious spam emails. Just like the name of the virus suggests, it appends .java file extensions to the targeted data.

.Java virus has several versions which differ from each other only by an email address included in the suffix of the encrypted file. Currently, the malware uses the following file extensions:

• Decrypthelp@qq.com.java,
• .[crazy.hamster@aol.com].java,
• .[badfail@qq.com].java,
• .id-[random numbers].java,
• .[workup@india.com].java,
• .id-8.[sabantui@tutanota.com].java.

Files encrypted by Java ransomware are usually the most useful ones, e.g., business documents, scientific data, photos, video files, etc. So, there is no surprise why hackers are successful in collecting ransoms from PC users.

Following data encryption, Java virus drops a ransom note in FILES ENCRYPTED.TXT file. However, different versions of malware might name this text file differently. Though, the provided instructions remain the same:

All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail sabantui@tutanota.com
Write this ID in the title of your message B8F053EC
In case of no answer in 24 hours write us to theese e-mails:udacha@cock.li
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files.

As you can see from the abstract, victims are asked to contact cyber criminals via provided email address. However, Java ransomware virus is known for using a couple of different emails for communicating with victims:

• sabantui@tutanota.com
• Fast_Decrypt_and_Protect@Tutanota.com
• udacha@cock.li,
• ecrypthelp@qq.com.

Developers of .Java virus seems to be generous and promise free decryption for 5 files as a guarantee that they actually have a working data recovery tool:

Free decryption as guarantee
Before paying you can send us up to 5 files for free decryption. The total size of files must be less than 10Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)

However, security specialists do not recommend taking this offer and having business with cyber criminals. There is no guarantee that you will receive a needed decryption tool^[2] once you transfer the demanded sum of Bitcoins.

For this reason, we suggest you remove .java file extension virus and try to either recover files from backups or use alternative recovery tools such as official Rakhni decryptor (used to decrypt Dharma ransomware files.) This way you will avoid financial losses and protect your computer from further malware infiltration.

Start ransomware .java removal by downloading a reputable security software, such as FortectIntego. The detailed instructions are provided at the end of this article to ensure that you perform ransomware elimination safely and without any complications. In spite of that, we kindly ask you to follow the guidelines carefully.

Be careful with emails sent by Tim Brooks – the attachment includes ransomware

Researchers from ZonderVirus.nl^[3] have spotted that the file-encrypting virus is distributed via malspam campaigns. The malicious attachments holding an executable of the ransomware are sent as fake invoices from a sales department. The sender of the message is named Tim Brooks. However, it is merely an attempt to make the email look genuine.

Therefore, many people were convinced that the letter came from a legitimate company and opened the infected attachment. As a result, the ransomware infiltrated the system and began its bogus activity. Note that the crooks might disguise the malware under receipts, banking statements or other vital documents.

Likewise, you should be extremely cautious when opening email letters.^[4] If you get a receipt for a specific purchase, you do not recall making, do not open the message. Even accidental clicks might trigger an installation of various high-risk computer infections and lead to enormous financial losses.

Additionally, cybercriminals might hack into social media accounts^[5] and deliver messages with infected links to the people on the friend list. Thus, if you receive a dubious text from your peer, contact him or her in person to make sure that their account is safe.
