Java ransomware hacks computer system with AES encryption. While the system can safely operate, the data suffers the attack. All the documents, pictures, videos and many other types of data undergo the sophisticated transformation.
The hack is for ransom. The crooks need to communicate with the victims in order to collect the payment for decryption. That is basically why the encryption spares files in the folders that presumably ensure the system operability and connectivity. Other files become scrambled, their names transform as the attack add an extra extension or appendix. An extra extension may look as follows:
In the wild, a user nicknamed Alex2k17 has reported the attack has added the following sequence to the encrypted files: .id-1201A1A8.[email@example.com].java. Thereby, according to the user’s report, the ransomware renames a file called info.txt to nfo.txt.id-1201A1A8.[firstname.lastname@example.org].java.
Java is a far cry from a brand new release of ransomware. It represents a Dharma/Crysis family of encryption-for-ransom attacks. Apart from the .Java extension, the family also features such extensions as dharma, .wallet, .zzzzz, .onion, .cesar, .arena, .cobra etc. The list is not exhaustive.
Introduction of the ransomware typically occurs via malspam. Ransomware watchers have spotted and reviewed a spam faking a Sales Department message. Any such campaign ultimately wants the user to open a content attached. The opening either directly triggers the download and installation or requires the user to activate a misleading macro.
.Java ransomware – Info.hta ransom note
An installed instance of Java ransomware reports to the remote server. This creates a unique ID for the computer system concerned, which states for the random number in the .id-[random numbers].java renaming pattern. The encryption process runs in parallel with the ransom note creation and dissemination. The note dropped by the Java ransomware would say that your files have been encrypted due to a security problem. Whether you agree with such interference, the message demands a payment for the decryption. It specifies email for further communication (which you may also see as a part of the name for any files hit by the encryption). Method of payment required is a bitcoin transaction.
Needless to say, any payments to the crooks do not ensure ultimate decryption. Besides, these provide further incentives for the criminals to deploy similar attacks. Free help for the users concerned is available below as the Java malicious encryption removal guidance.
Automated cleanup to remove Java virus
1. Click the button to download the stub installer and go through several setup dialogs. Once the tool is up and running, click Start Computer Scan
2. Wait until the cleaner checks the PC for Java ransomware malicious code. As soon as the scan is completed, the report will list all malware objects spotted in the system. Make sure the entries for detected infections are checked, and select the Fix Threats feature. This will result in malware removal and system remediation, so you should now be good to go.
Restore the encrypted files
Java encryption is a sophisticated data modification. There is no simple and single solution to cover all the cases. Transferring the ransom as demanded by the crooks is not the way either.Kindly apply the methods outlined below as they have been carefully developed to provide a recovery help for the most severe cases of encrypting assaults.
Data recovery with automatic software
Good news is that the virus actually deals with copies of the files. The originals have been deleted. The removed data still can be restored by virtue of such tools as Data Recovery Pro.
Shadow Volume Copies
As Windows creates backups at given periods of time, a victim is advised to address relevant restore points. Unfortunately, the method cannot apply unless the System Restore had been enabled prior to the invasion. Please also note the recovery returns files as saved before the time associated with the restore point addressed.
- Previous Versions dialog to target individual files
One can open Properties for any file. The menu has a tab called Previous Versions. It indicates versions of a file that have been backed up.
To make use of the feature, right-click an affected file and choose Properties in the drop-down list. Proceed with clicking the above-mentioned tab. You can opt between the Copy or Restore procedures, the former enabling to copy the item into the location specified by the user.
Backups and removing remaining traces of ransomware
Prevention is the best cure. If you stick to making regular reserve copies of your data and store those outside your operating system, the impacts by the ransomware are very limited. However, prior to copying the data from backups into the system hit by Java ransomware, make sure the removal of this virus has completed.
Your manual removal attempts may kill the ransomware in general. In most of the cases, some remnants manage to survive and are still capable of causing a significant damage. Please apply a reliable anti-malware scanner to detect and remove, if applicable, any remaining infections.
