Full Packet Capture
Arkime (formerly Moloch) is a large scale, open source, indexed packet capture and search tool.
This project has experienced significant growth, adoption, and
change over the last eight years. We are now at a new milestone
and believe it’s the right time to rename our project to Arkime!
Why Arkime
(/ɑːrkɪˈmi/)?
Meet the developers and other Arkimists at our Office Hours.
Augment your current security infrastructure to store and
index network traffic in standard PCAP format.
Arkime is not meant to replace Intrusion Detection Systems (IDS),
instead it provides more visibility.
Security
Access to Arkime is protected by using HTTPS with digest passwords or by using an authentication providing web server proxy. All PCAPs are stored on the installed Arkime sensors and are only available through the Arkime web interface or API. Arkime supports encrypting PCAP files at rest.

Scalability
Arkime is designed to be deployed across multiple clustered systems providing the ability to scale to handle multiple gigabits per second of traffic. PCAP retention is based on available sensor disk space while metadata retention is based on the scale of the Elasticsearch cluster. Both can be increased at anytime.
Interface
A web application is provided for PCAP browsing, searching, analysis, and PCAP carving for exporting. Arkime stores and exports all packets in standard PCAP format allowing you to use your favorite PCAP ingesting tools during your analysis workflow.
APIs
APIs are exposed that allow PCAP data and JSON-formatted session data to be downloaded directly.

Search
The search bar allows for powerful search queries to narrow down the data. Click the owl for available fields.
Session detail
Get more information about any session and view the session's packet data by clicking the "+" button.
Value actions
Hover and click any value to view a dropdown menu of actions, like applying that value as search criteria.
Export PCAP
You can export search results as PCAP or CSV by clicking the "Actions" () drop down menu on the top right.
Timeline search
Click and drag an area in the timeline to filter sessions by time.
Country search
Click a country on the map to apply it as search criteria.
SPI View Page

Toggle categories
Click on any section to open or close any field category.
Search for fields
Search for fields within a category by using the input box within a category.
Toggle fields
Click on a field in the top section of a category to toggle the field's visibility. You can also click the load/unload all buttons to load/unload all the fields in that category.
Cancel Load
Click the cancel button on the top right of the page if the page is taking a long time load data or you made a mistake when you issued a query.
SPI Graph Page
