Industry-wise, Abyss shows a concentration in the Business Services, Technology, Healthcare sectors. These industries are frequently targeted because they manage sensitive data, critical operations, or have lower tolerance for operational downtime โ conditions that increase ransom payment likelihood.
Like most modern ransomware operations, Abyss likely employs a double extortion model: encrypting victim files while simultaneously exfiltrating data, creating dual pressure to pay the ransom. Victim organisations that refuse payment face having their data published on the group's dark web leak site.
