Latest News – Java Ranswomare New Variant

Updated: April 2018 – .java ransomware Has a New Version Which Increased Infection Rate

The .java iteration of Dharma ransomware has still remained active so far, but the bad news is that the newer version of the virus, using the .arrow file extension has been detected to be featured in new e-mail spam messages, which may also be used to spread the .java files version of Dharma. The e-mails may contain fake document types of files which cause the infection upon being opened.

Updated February 2018 – .java Dharma Uses a New Spam Campaign

.java ransomware variant of Dharma Ransomware has been reported to perform new different types of activities on the computers of victims primarily concerning it’s payload dropping mechanisms. The malware also has several changes in the e-mails which it uses for ransom. Dharma’s .java variant uses the following e-mails in it’s latest versions:


Other than that, Dharma’s .java variant still uses the same malicious practice as it did with it’s older variants, sending spam e-mails containing the infection file which infects via RDP (Remote Desktop Protocol), disguised as an important document of some sort.

.java Files Virus – How Does Java Ransomware Infect your system?

The infection process of this ransomware virus is most likely conducted via a well-known technique – spam e-mail messages. Such techniques aim to deceive victims into opening a malicious e-mail attachment by believing it is a legitimate document. The e-mail attachments are sent via well-designed spam e-mails that make them appear genuine.

Always check the sender and make sure you recognise their domain name.

  • Invoices.
  • Court order.
  • ATO Documents
  • Banking statements.
  • Receipts of purchases the user does not recall in making.
  • Other important documents.

The e-mails, carrying this new .java files variant of Dharma ransomware are also cunningly made and they may even deceive experienced users. Here is how such e-mail, carrying the infection file of this variant of Dharma ransomware.

Dharma Ransomware – .java Files Virus – Malicious Activity

The malicious files of Dharma .java ransomware may be located in the following Windows directories:

  • %AppData%
  • %Roaming%
  • %Local%
  • %LocalLow%
  • %Temp%

In addition to malicious files, the virus may automatically execute them in order to perform other activities on the infected computer, such as interact with the Run and RunOnce Windows registry sub-keys, that have the following locations:

–> HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
–> HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\

Since those keys are responsible for running programs alongside Windows Boot, the virus may also begin to delete the shadow volume copies on the infected machine which makes restoring your files via backup impossible. To do this, the .java file virus may use the following commands in Windows Command Prompt by running a script as an administrator that executes them in quiet mode.

bcdedit /set {default} recoveryenabled No
vssadmin delete shadows /for={volume} /oldest /all /shadow={ID of the Shadow} /quiet

After doing so, the java ransomware variant of Dharma is ready to encrypt your important files.

In order to protect yourself from the Java variant of  Dharma, or from any other ransomware, it is important that you use good computing habits and security software. First and foremost, you should always have a reliable and tested backup of your data that can be restored in the case of an emergency, such as a ransomware attack.

You should also have security software (please talk to us about our recommendations) as most antivirus does not give you a complete protection

Last, but not least, make sure you practice the following good online security habits, which in many cases are the most important steps of all:

  • Backup, Backup, Backup!
  • Do not open attachments if you do not know who sent them.
  • Restrict RDP access
  • Make sure all Windows updates are installed as soon as they come out! Also make sure you update all programs, especially Java, Flash, and Adobe Reader.

  • Make sure you have a recommended security software installed.
  • Use complex passwords and never reuse the same password at multiple sites.
