Study Notes

Computer Forensics and Cyber Crime: Searching and Seizing Evidence

  • Computer forensics involves a legal approach to finding digital evidence in cybercrime scenes.
  • Pre-search activities include:
    • Gathering information to prepare for scene arrival.
    • Determining the number, type, and size of computers present.
    • Assessing risks from personnel affecting evidence.
    • Recognizing the volatility of evidence.
    • Obtaining judicial authority for data gathering.
    • Seeking expertise from non-departmental experts.
    • Engaging in social engineering.
    • Conducting dumpster diving for potential evidence.
  • Warrant preparation and application:
    • Warrants need review by legal counsel and computer experts before submission.
    • Probable cause is mandatory to demonstrate a committed crime at the specific location.
  • Seizing equipment:
    • Justification for seizing equipment is required (not just the search).
    • Explicit permission is needed to seize all hardware and storage devices to ensure constitutional justification.
    • Criminal contraband, fruits of the crime, or evidence may be seized without a warrant.
  • No-knock warrants:
    • No-knock warrants might be used in exigent circumstances:
      • Nature of the crime.
      • Potential for evidence destruction.
      • Sophistication and maturity of the target.
      • Absence of the resident.
  • Secondary/multiple warrants:
    • Secondary warrants may be needed in cases dealing with complex crimes, such as identity theft related to drug trafficking. This could also be true for networked computers with off-site storage.
  • Plan Preparation and Personnel Gathering:
  • Use SMEAC (Situation, Mission, Execution, Avenues of approach and escape, Communications) for pre-investigation planning.
  • On-scene personnel:
    • On-scene personnel may play various roles (e.g., case supervisor, arrest team, scene security, interview team, sketch/photo team, physical search team, seizure team).
    • Seizing team would be responsible for bagging/tagging evidence.
  • Traditional equipment:
    • Evidence tape, packing tape, evidence storage containers and labels.
    • Anti-static bags, conductive bags, and Faraday bags to prevent loss of data and shield wireless devices.
  • Computer-specific Equipment:
    • Multiple boot disks, backup hardware, new hard drives, color scanners, color printers, anti-virus software (must be the most up-to-date), imaging software, and application software.
  • On-scene activities:
    • Steps involved in serving a warrant: Knock, Notice, Document.
    • Securing the crime scene, including dealing with dangerous individuals, hazards, and removing personnel from the area.
    • Ascertaining network connections for appropriate actions.
    • Disabling network access (ideally by a network administrator) and protecting computers.
    • Collecting literature related to the underlying activities or offenses.
    • Determining the need for external specialists (e.g., mainframes, minicomputers, hacker computers).
    • Documenting date, time, description of computer (including damage), identifying information for investigators and personnel, finding all present persons, all available clues & leads, & any investigative software used.
    • Photos/videos used as evidence to counter corruption and contamination efforts by opposing sides.
    • Identifying potential evidence (non-digital, trace evidence, like hair, fibers, and fingerprints), as well as any other computer components (external hard drives, peripherals).
    • Documentation of circumstantial connections include post-its, printouts, & paper types.
    • Investigating potential evidence like desktops, monitors, keyboards, phones, wallets/purses, clothing, trash cans/bins, printers, and the computer itself.
    • Seizure and documentation of evidence for the warrant scope. All annotation is done in ink. Comprehensive notes are taken.
    • Seizing computer steps: Document the status (photos, sketches, etc.) before powering off the computer, include back of computer and connections. Place evidence tape over disk openings after powering off and label all cords & empty slots.
  • Bagging and tagging:
    • Use chain of custody logs to track all evidence.
    • Labels should contain investigator initials, date found, and location of evidence.
  • Transport and packaging:
    • Use protective measures to avoid damage from temperature, oil, dirt/dust, magnetic fields, and other environmental factors.
  • Post-Seizure activities:
    • Who controlled the digital evidence, when and how was it collected/stored, where was it when collected, what kind of device held the evidence, who had access to equipment, and who owned the equipment.
    • Rely on traditional transport to exit the crime scene and properly record the contents being transferred, review shipping manifests, and enter into appropriate evidence control systems for analysis.
