Thanks to @BiebsMalwareGuy and @MeegulWorth, samples were found and further analysis of the ransomware could be done. When infected, a victim's data files will be encrypted using AES encryption and will be told they need to pay a ransom of 1.24 bitcoins or ~500 USD to get their files back. Unfortunately, at this point there is no known way to decrypt a victim's encrypted files for free.\r\n\r\nAt this time we do not currently know how the Cerber ransomware is being distributed, but according to SenseCy, it is being offered as a service on a closed underground Russian forum. This means that it is probably a new Ransomware as a Service, or RaaS, where affiliates can join in order to distribute the ransomware, while the Cerber developers earn a commission from each ransom payment." }, { "type": "observed-data", "spec_version": "2.1", "id": "observed-data--56e12572-a3a4-40de-8e11-4f58950d210f", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f",
