Corporate espionage evidence on an iOS 17 device · a court report in 72 hours
An investigation of suspected corporate espionage on an iPhone 15 Pro Max (iOS 17.2.1) urgently served by the public prosecutor's office. WhatsApp + Signal + Photos metadata · a 72-hour court deadline · compliance with CCP Article 134 + ISO/IEC 27037. The DSET digital forensics team produced a full image + an expert report without breaking the chain of evidence.
01 The Challenge
An allegation that corporate secrets had been transferred to a rival firm from a senior executive's iPhone. The device owner would not give the PIN · there is a remote wipe threat · iCloud active. The new iOS 17 security features (Stolen Device Protection · the possibility of Lockdown Mode) + no checkm8 on the A17 Pro chip. A CCP Article 134 compliant expert report mandatory within 72 hours · the slightest error in the chain of evidence drops the case. The court under pressure from detention periods.
02 DSET's Approach
T+0 · Faraday isolation
At the moment of service the device in a Faraday Tent · cellular off · WiFi off · the iCloud remote wipe command was blocked before it could be issued.
T+4h · Access strategy
checkm8 closed for iOS 17.2.1 + A17 Pro. The GrayKey 8.4.1 version was scanned for iOS 17 support · a 6-digit PIN brute force estimated at ~12 hours.
T+8h · PIN brute force
GrayKey was connected · the PIN '147329' was cracked in 11 hours 42 minutes. A BFU (Before First Unlock) extraction became possible.
