Phobos Ransomware is based on the Dharma (aka CrySIS) malware that first appeared at the beginning of 2019. It spreads into several systems via compromised Remote Desktop Protocol (RDP) connections. This malware does not use any UAC bypass methods. Unlike other cybercrime gangs that go after big hunts, Phobos creators go after smaller firms that don’t have sufficient funding to pay massive ransoms. This ransomware usually targets healthcare providers, with victims in the United States, Seychelles, Portugal, Brazil, Indonesia, Germany, Romania, and Japan. Its perpetrators demand a little ransom payment, which appeals to victims and enhances the chances of payment. The average Phobos ransom payment in July 2022 was $36,932
Phobos encrypts data & files and keeps them locked until a ransom is paid. All encrypted files are renamed with the “.phobos” extension, as well as the victim’s unique ID and email address.
