Disclosure context

About Blackbyte

BlackByte is a ransomware-as-a-service (RaaS) operation that emerged in October 2021, primarily motivated by financial gain through double extortion tactics targeting organizations across multiple sectors. The group is suspected to operate from Russia or former Soviet states based on their use of Russian-language forums and avoidance of targeting organizations in Commonwealth of Independent States countries, though they maintain no confirmed links to other established ransomware families. BlackByte operators typically gain initial access through vulnerable Microsoft Exchange servers, phishing campaigns, and exploitation of remote desktop protocol (RDP) services, employing tools such as Cobalt Strike for lateral movement and data exfiltration before deploying their custom ransomware payload that uses AES-256 encryption with RSA-2048 key protection. The group has demonstrated particular focus on critical infrastructure sectors, with the FBI and CISA issuing joint advisories in February 2022 highlighting attacks against organizations in government, healthcare, manufacturing, and education sectors, including notable incidents affecting San Francisco's transportation authority and multiple healthcare systems across the United States. BlackByte remains active as of 2024, continuing to evolve their tactics and maintain their leak site for publishing stolen data from victims who refuse to pay ransoms. The group has been linked to 147 public disclosures across our corpus. First observed on a leak site on October 4, 2021; most recent post July 30, 2025. The operation is currently inactive.
