Kill Chain Phase

• Collection (TA0035)

Platforms: Android, iOS

What to Check

• Identify if Call Log technique is applicable to target mobile environment
• Check Android devices for indicators of Call Log
• Check iOS devices for indicators of Call Log
• Verify mitigations are bypassed or absent (1 known mitigations)
• Assess detection coverage (1 detection strategies)
