Anfang der weitergeleiteten E-Mail: Von: Christoph R. Winter <[email-masked]> Betreff: Follow-up: Case OE0104912510005 – Supplemental Forensic Evidence Datum: 28. Feb. 2026 um 23:05 An: [email-masked] Subject: Supplemental Forensic Evidence regarding Persistent Persona Infiltration and Octagon Circle Compromise (Case OE0104912510005) Technical Summary: Manual forensic analysis of the provided sysdiagnose (Build 23D127) has identified a sophisticated identity-layer compromise that bypassed standard MVT (Mobile Verification Toolkit) signatures. The compromise is characterized by a persistent Persona-Infiltration and the exploitation of the Mach-Voucher system to hijack secure processes. Key Findings for Engineering Review: Unauthorized Persona Adoption (2026-01-26): At 11:43:55Z , the usermanagerd log (usermanagerd.log.1) confirms the successful adoption of shadow personas: FEEDEEEE-DDDD-CCCC-BBBB-5555000001F5 (Persona 200) FEEDEEEE-DDDD-CCCC-BBBB-0000000001F5 (Persona 1000) This was achieved via replacePersonaMachPortVoucher by PID 244 and PID 793 . Keybag & Encryption Bypass: Simultaneous with the persona adoption, the system reported a critical failure: Failed to get data with contents of file /private/var/keybags/nextsession.kb: [2: No such file or directory] This indicates a Man-in-the-Endpoint attack during an Apple ID re-authentication event, allowing the attacker to inject malicious identities into the local trust manifest. Octagon Trust Circle Inconsistency: The otctl_status reveals an anomaly with 6+ active Peer-IDs despite only one physical device being authorized. The absence of MemberName for these peers suggests an anonymous Shadow-Pairing configuration within the Octagon circle. Exfiltration (74 GB Peak): Massive cellular data exfiltration (Operation ID: 954F1D6466466963 ) was conducted via cloudd using the QUIC protocol with the allows-expensive flag set. The exfiltration masqueraded as standard "Contacts" and "Photos" synchronization under the context of the malicious shadow personas. Conclusion: The evidence points to State-Grade Spyware utilizing kernel-level persistence and identity-overlay techniques to exfiltrate data while bypassing standard iOS sandbox logging. ... more
