What happened
Ransomware incidents usually evolve through several stages: initial access, privilege escalation or credential abuse, lateral movement, data theft and encryption or extortion. Ransomware or extortion activity represents the impact stage of the chain, after earlier access and control have already created the conditions for disruption.
Ransomware reporting matters because initial access, identity abuse, lateral movement and recovery impact often repeat across victims. The incident can affect operations and may also involve data theft, so recovery and investigation need to address both availability and exposure of information.
Threat actors are leveraging Microsoft's Graph API to identify lucrative targets, then passing their access to extortion groups like ShinyHunters.
