...all of my files look like that
 
 Hulu.url.id-02102C04.[gettkey@qq.com].java

You are dealing with Dharma Ransomware, not Btcware Ransomware.

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, .cesar, .arena, .cobra or .java extension appended to the end of the encrypted data filename (i.e. .id-A04EBFC2.[bitcoin143@india.com].dharma, .id-480EB957.[legionfromheaven@india.com].wallet, .id-5FF23AFB.[Asmodeum_daemonium@aol.com].onion, .id-EB214036.[amagnus@india.com].zzzzz, .id-01234567.[gladius_rectus@aol.com].cesar, id-BCBEF350.[chivas@aolonline.top].arena, .id-BCBEF350.[cranbery@colorendgrace.com].cobra, .id-406B4F5A.[black.mirror@qq.com].java).

Unfortunately, there is no known method to decrypt files encrypted by the .java variant of Dharma (CrySiS) without paying the ransom. 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.

Hello everybody,

 

My server have been infected by F88.Wallet vírus.

 

According to ID_Ransomware this virus is 

 

identified by

  • sample_extension: .[<email>]-id-<id>.wallet
  • ransomnote_email: decrypt@btcbtcbtc.top

 

On the files they left an email adress decrypt@btcbtcbtc.top

 

I know I shouldn´t, but I have payed the ransom, they sent me .exe program but it doesn´t work.

 

So my advise to you all is DO NOT PAY THEM they will not give you a solution.

 

I will appreciatte someone could help me finding a solution.

 

Regards,

 

Joel

The .wallet variant is based on the latest AES-256 version of the BTCWare Ransomware family which uses a different RSA-1024 key and is not decryptable unless you get the private AES key from the criminals. There is no way to bruteforce the key for this variant.

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.

Most security experts will advise against paying the ransom demands of the malware writers because doing so only helps to finance their criminal enterprise and keep them in business. One of the reasons that folks get infected is because someone before them paid the bad guys to decrypt their data. The more people that pay the ransom, the more cyber-criminals are encouraged to keep creating ransomware for financial gain. Further, there is never a guarantee that paying the ransom will actually result in the restoration (decryption) of your files.

Some ransomware victims have reported they paid the ransom and were successful in decrypting their data. Some victims have reported paying the ransom only to discover the criminals wanted more money...demanding additional payments with threats the data would be destroyed or exposed. Still others have reported they paid but the cyber-criminals did not provide a decryptor or a key to decrypt the files, while others reported the decryption software and/or key they received did not work, resulted in errors and in some cases caused damage to the files. Most cyber-criminals provide instructions in the ransom note that allow their victims to submit one or two limited size files for free decryption as proof they can decrypt the files. However, decryption in bulk may not always work properly or work at all. In some cases victims may actually be dealing with scam ransomware where the malware writers have no intention or capability of decrypting files after the ransom is paid.

Keep all this in mind if you are considering paying the ransom since there is never a guarantee decryption will be successful or that the decrypter provided by the cyber-criminals will work as they claim...and using a faulty or incorrect decryptor may damage or corrupt the files even further. The criminals may even send you something containing more malware...so why should you trust anything provided by those who infected you in the first place.

Newer variants of BTCWare (.blocking, .encrypted, .aleta, .crypton/.gryphon, .nuclear, .wyvern, .payday, .shadow and .wallet are AES-256 versions of the malware which uses a different RSA-1024 key and are not decryptable unless you pay the ransom and get the private AES key from the criminals. There is no way to bruteforce the key for any of these versions. Read Demonslay335's comments in Post #293 and Post #432.

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.

Hello ,

 

today morning 15/1/2018 I have been infected too by ransomware and my files are encrypted. 

The note is in a file called: instruction.html and the files extension have been altered to .btc.

The extortionist email mentioned in the ransom note is : helpforyou@airmail.ccc

Will the BTCWareDecrypter work for my case?

Do i have to do something else to remove the trojan before running a decrypter?

I had both eset nod security and malwarebytes installed and running but none of the 2 stopped the ransomware from coming in. I guest it must be from RDP...

I have submitted the instruction.html for analysis

thanks

GlobeImposter, BTCLocker and Jigsaw Ransomware all use the .btc extension.

Did you submit (upload) any 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? Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections.

I did submit the ransom note called instruction.html.

My problem is that after using Eset security to scan for viruses all files named instruction.html was found as threat and I have now deleted them... So now I do no longer have the ransom note. Can I do anything?

The email mentioned in the ransom note is helpforyou@airmail.cc.

Files can be extracted from the Quarantine. Or use the technical support of ESET.
This is the only European anti-virus company that detects all such notes as a virus.
