Ghost is a ransomware threat actor associated with Ghost ransomware, also referred to as GhostLocker in some reporting. The group has been described as evolving from GhostSec, an actor originally rooted in hacktivist activity linked to the Anonymous ecosystem, and later adopting ransomware and ransomware-as-a-service style operations. Ghost has also been reported as collaborating with other hacktivist-turned-extortion actors such as Stormous and SiegedSec. Ghost is known for rapidly exploiting newly disclosed vulnerabilities in unpatched internet-facing systems, including Ivanti Connect Secure and related appliances. Reporting indicates the group can move quickly after patch releases, using vulnerability exploitation for initial access rather than relying solely on phishing. After compromise, Ghost has conducted data theft and used double-extortion tactics, combining encryption with threats to leak stolen information. The actor therefore demonstrates a blend of initial access via vulnerability exploitation, exfiltration, and extortion-oriented post-compromise operations. Available information supports characterizing Ghost primarily as a financially motivated ransomware actor, despite its roots in hacktivism. High-confidence reporting in the supplied material does not establish a specific national origin, nor does it provide sufficiently corroborated victim geography or sector concentration beyond opportunistic exploitation of exposed vulnerable systems.
