Has anyone decrypted Dharma .heets variant?

Recommended Posts

Hello,

Unfortunately, DHARMA cannot be decrypted without contacting the ransomware authors and paying the ransom.

Some versions of Dharma Ransomware (old and new) can be decoded by a free decoder from Kaspersky.

I read about the decoding of .heets files by specialists from another company, but now I can’t find this message. They said that it was a lighter version of decryption than versions that were already decrypted. But I myself did not see the decoding of this variant.

Decryption of certain variants is only possible because of seized encryption keys.  DHARMA uses a secure encryption scheme that is unbreakable using current techniques and hardware.  Unless you pay the ransom and rely on the benevolence of the authors to send you a working key and decryptor or a security firm was able to seize encryption keys from servers under control of the cybergang. DHARMA is not decryptable with third-party tools.

Of course. This is true. This has recently allowed Kaspersky Laboratories to add new options to the decryption list, which in the ID list of the Ransomware are collected under one Dharma identification (.cezar Family). Despite this, they differ not only in visual indicators. 
They are distributed by different groups of extortionists from different countries, not only from Ukraine.

For example, the .heets extension has had a near 100% data recovery rate.

Coveware doesn't decrypt files for victims. They negotiate lower prices with the criminals who make/distribute the ransomware so that they can get their hands on the decrypters and private keys, and then sell their "service" to victims as a cheaper way to recover their files.

I talked with Michael about this, and he says (somewhat paraphrased) the stats you linked to are about which ransomwares give valid/working private keys when you pay vs which ones do not.

Fixed typo.
