What is a .IOC file?
IOC is an OpenIOC file describing indicators of a security compromise. Created by Mandiant.
- Did you know
- OpenIOC describes the tell-tale signs that a system has been breached.
- OpenIOC describes threat indicators using Boolean AND and OR logic and defines over 500 indicator terms that can be extended as needed.
- Mandiant released OpenIOC with free tools such as the IOC Editor for building indicators and a finder for scanning a single host.
- What Analyser reads
- Identify and read more security and forensics files: OpenPGP messages/keys/signatures (.pgp/.gpg/.sig - armor type, packet walk, key algorithm and user ID, secret-key warning), YARA rules, Snort/Suricata IDS rules, STIX/OpenIOC threat intel, Fiddler captures (.saz), 1Password exports (.1pux), Apple Keychain, KeePass 1.x (.kdb), Microsoft keys (.pvk) and AFF/AFF4 forensic images.
- Depth of analysis
- .IOC is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .IOC file
- Drag a .IOC file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
