[ GPS • DEVICE • OWNER • PAYLOAD • HASH ]
Exifer is a next-generation cybersecurity-focused EXIF and metadata forensic analyzer for Android.
It is designed to help users, investigators, journalists, and privacy-aware individuals detect:
- Hidden metadata leaks
- Location exposure (GPS stalking risk)
- Device fingerprinting identifiers
- Editing/tampering traces
- Embedded payload signatures (ZIP/PDF/DEX/ELF)
- Integrity hashes (SHA-256)
- High entropy steganography suspicion
