Raw top scorer Oct-30 AD CS chain was excluded as exact CY-TOP-IAS-001 duplicate. Selected passkey/help-desk vishing→AiTM/device-code/session compromise→attacker MFA persistence→Graph/SaaS collection; AuthMask CVE deprioritized because no public exploitation evidence.

IAS-E-0008
Active cloud intrusions use passkey/MFA/SSO help-desk lures to drive AiTM or device-code authentication, compromise sessions/tokens, add authentication methods, perform Graph reconnaissance and access M365 content.
Passkey protocol flaw, one actor/campaign, representative prevalence, or that every service access event equals exfiltration.

IAS-E-0009
Multiple recent IR engagements show targeted help-desk vishing and fake passkey/MFA enrollment leading to session theft or attacker authenticator enrollment, Graph tenant inventory and rapid SharePoint/OneDrive/mailbox collection; one executive case generated >100,000 FileAccessed events in a burst consistent with library cloning.

لا توجد run_events تاريخية لهذه الجولة؛ تُعرض حالات Lifecycle أعلاه كما هي من سجل Run ولا يتم اختلاق أحداث بديلة.
UNC6671 uses help-desk vishing, AiTM SSO compromise, attacker-controlled MFA registration and automated Microsoft 365/Okta/SaaS data theft; replayed session cookies can retrieve content in ways recorded as FileAccessed rather than FileDownloaded.
UNKNOWN
Supports
Actor-specific lineage, MFA persistence and FileAccessed exfiltration semantics.
Does not prove
That all passkey-themed campaigns are UNC6671, that every FileAccessed event is exfiltration, or cross-vendor actor identity.

IAS-E-0011
Arctic Wolf tracks widespread PREY-0058 IT-impersonation/vishing that bypasses MFA through social engineering, gains Microsoft 365/SaaS access and performs rapid automated data exfiltration followed by extortion; overlap with UNC6671 is reported without identity equivalence.
UNKNOWN
Supports
Independent active-exploitation evidence and actor-identity boundary.
Does not prove
PREY-0058 equals UNC6671 or every extortion brand, or representative prevalence.
