    Important
    • The local archive does not have encryption, and remains on the endpoint until deleted. This might allow access to sensitive information to anyone with access to the file system or reveal the presence of an ongoing investigation.
    • Evidence archives take up hard drive space and may impact endpoint performance.
  4. Click Download TMIRT (download_icon=5c7476c2-cf15-4572-b7cd-5fc67a57d22f.png) to download the Trend Micro Incident Response Toolkit.
  5. Deploy the toolkit to the endpoints on which you want to collect evidence.
  6. Execute the toolkit.
    1. Extract the contents of the zip archive.
    2. Execute TMIRT.sh as the root user.
  7. (Optional) If you do not have enough privileges to execute scripts, execute the following commands.
    1. Discover the endpoint OS architecture by executing the uname -m command.

      Important
      • For AArch64 or ARM64 architecture, use the TMIRT-arm64.tgz toolkit.
      • For i386 or i686 architecture, use the TMIRT-x86.tgz toolkit.
      • For AMD64 or x86_64 architecture, use the TMIRT-x64.tgz toolkit.
    2. To extract the toolkit from the TGZ file, execute the ./tar -xf command with the correct TMIRT version based on your OS architecture.
    3. To begin collecting evidence, execute ./TMIRT evidence --config_file ./config.json.
  8. Upload the evidence packages the toolkit generates to the Forensics app.
