Digital & Cyber Forensics

Bit-Stream Acquisition, Hex Carving, Mobile Forensics & Section 65B IEA

"Deleted never means destroyed. Every digital packet, cluster, and volatile register leaves an unalterable footprint."

The identification, cryptographic preservation, extraction, and documentation of digital evidence from hard drives, mobile devices, cloud repositories, and network traffic for courtroom presentation.

CORE FORENSIC PRINCIPLE

Foundational Admissibility Law

Electronic Integrity: Digital evidence must be acquired using verified hardware write-blockers and validated with cryptographic hashing (SHA-256) ensuring zero alteration of original magnetic/flash states.

Judicial Standing: Strict statutory prerequisites under Section 65B IEA / Section 63 BSA requiring proof of unbroken chain of custody and instrument calibration.
SCIENTIFIC & EMPIRICAL BASIS

Analytical Methodology

File carving through header/footer analysis, parsing master file tables (MFT), unallocated cluster reconstruction, and volatile RAM capture before power-down.

  • Physical isolation using Faraday bags to prevent remote device wipe signals
  • Cryptographic SHA-256 bit-stream disk imaging (E01 / RAW DD format)
  • Authoring Section 65B Indian Evidence Act / Section 63 BSA electronic certificates
STANDARD OPERATING CASWORK WORKFLOW

How An Examiner Investigates This Evidence

From scene cordoning to laboratory instrumentation and final deposition.

01STAGE 01

Cryptographic Bit-Stream Acquisition

Connect drive through hardware write-blockers to generate exact bit-for-bit forensic image with matching SHA-256 hash.

02STAGE 02

Unallocated Cluster Hex Carving

Parse raw binary byte strings to reconstruct deleted files using file magic numbers (e.g., FF D8 FF E0 for JPEG).

03STAGE 03

Timeline Analysis & 65B Certification

Correlate MACB file timestamps, system registry hives, and EXIF geolocation to author a courtroom-ready certificate.

Primary Laboratory Instruments & Software

Official instrumentation deployed across accredited FSLs & independent crime labs.
