CoinVault ransomware: Retrieve data without paying the criminals

Victims of the CoinVault ransomware have a chance to retrieve their data without having to pay the criminals, thanks to a repository of decryption keys and a decryption application made available online by Kaspersky Lab and the National High Tech Crime Unit (NHTCU) of the Netherlands’ police.

CoinVault ransomware has been around for a while, encrypting victims’ files and demanding Bitcoins to unlock them. In order to help victims recover from an attack, the NHTCU and the Netherlands’ National Prosecutors Office obtained a database from a CoinVault command & control sever. This server contained Initialization Vectors (IVs), Keys and private Bitcoin wallets and helped to create the special repository of decryption keys. As the investigation is ongoing, new keys will be added when available.

“We have uploaded a huge number of keys onto the site. If we do not currently have records for a particular Bitcoin wallet, you can check again in the near future, because together with the National High Tech Crime Unit of the Netherlands’ police we are continuously updating the information,” – says Jornt van der Wiel, Security Researcher at Kaspersky Lab.

CoinVault has infected more than 1,000 Windows-based machines in over 20 countries, with the majority of victims in the Netherlands, Germany, the USA, France and the UK. Victims have also been registered in Belgium, Austria, Switzerland, Norway, Sweden, Luxemburg, Denmark, Slovakia, Slovenia, Spain, Italy, Hungary, Ireland, Croatia, Russia, Canada, Israel, the United Arab Emirates, China, Indonesia, Thailand, South Africa, Australia, New Zealand, Panama, the Dominican Republic, and Mexico.
