Did you find any ransom notes and if so, what is the actual name of the note?

I came across this ransomware earlier yesterday, couldn't find any information online regarding this one. Ended up saving what files we could and just wiping the machine.

Yes, all affected files are appended with .java

There was no ransom note present (not that I could see) but I didn't go digging for one either.

Any files that are encrypted with Dharma (CrySiS) Ransomware will have an id-<8 random hexadecimal characters>.[<email>] followed by the .dharma, .wallet, .zzzzz, .onion, .cezar, .cesar, .arena, .cobra, .java or .write extension appended to the end of the encrypted data filename as shown below.

.id-A04EBFC2.[bitcoin143@india.com].dharma
.id-480EB957.[legionfromheaven@india.com].wallet
.id-EB214036.[amagnus@india.com].zzzzz
.id-5FF23AFB.[Asmodeum_daemonium@aol.com].onion
.id-01234567.[gladius_rectus@aol.com].cezar
.id-01234567.[btc2017@india.com].cesar
.id-BCBEF350.[chivas@aolonline.top].arena
.id-BCBEF350.[cranbery@colorendgrace.com].cobra
.id-406B4F5A.[black.mirror@qq.com].java
.id-30B3DDC1.[mazma@india.com].write

Dharma (CrySiS) will leave files (ransom notes) with names like README.txt, README.jpg, Hello my vichtim.txt, Your personal data are encrypted!.txt, FILES ENCRYPTED.txt, Files encrypted!!.txt, info.hta.

You can submit (upload) samples of encrypted files, ransom notes and any contact email addresses or hyperlinks provided by the cyber-criminals to
ID Ransomware for assistance with identification and confirmation.

Unfortunately, there is no known method to decrypt files encrypted by the newer variants of Dharma (CrySiS) without paying the ransom and obtaining the private RSA keys from the criminals. If possible, your best option is to restore from backups, try file recovery software or backup/save your encrypted data as is and wait for a possible solution at a later time.

There is an ongoing discussion in this topic where victims can post comments, ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.

Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.

Thanks
