Disclosure context

About 0Mega

0Mega is a relatively obscure ransomware group that emerged in July 2022, operating with apparent financial motivations based on their extortion activities. The group's origin and affiliations remain unclear due to limited public documentation, though their targeting patterns suggest they operate as a smaller independent entity rather than a major Ransomware-as-a-Service operation. With only seven documented victims, 0Mega appears to employ targeted attacks primarily against business services organizations in the United States, though specific details about their initial access vectors, encryption methods, or data exfiltration practices have not been extensively documented by major security firms or law enforcement agencies. The group has maintained a low profile with no widely reported high-profile attacks or significant ransoms that have garnered attention from CISA, FBI, or prominent security researchers like Mandiant. As of current reporting, 0Mega's operational status remains uncertain due to the limited intelligence available about their recent activities or any potential law enforcement disruption efforts. The group has been linked to 7 public disclosures across our corpus. First observed on a leak site on July 14, 2022; most recent post January 25, 2024. The operation is currently inactive.
