TOPSECRETSTRAP1 XKEYSCORE HELPER NOTES There are several new and updated features in this release of the XKEYSCORE Palantir helper: Summary/Histogram import of data 0 Data sourcing for XKEYSCORE queries 0 Fixes for Ul redraw bugs on query list refresh Fixes for disappearing links Summary import This feature is intended to mirror the functionality in XKEYSCORE for creating histogram grids over a query. It allows for a large dataset to be reduced down in size considerably while still maintaining useful data. As an example this is a histogram grid view over a small query in XKEYSCORE, histogrammed by From IP, To IP and To Port: Histogram Grid Page 1 of 1 .5 Clear Selection Export Displaying 1 - 39 of 39 Filter Fm IP T0 T0 Port Count E20644 IBBTB 38950 25193 53 32768 53 53 52835 47565 7?Fl?7 a CD As you can see, there are 19 entries for the top line here. In the old XKEYSCORE helper this would create 19 new events. While you still have the option of importing every row in an XKEYSCORE query as a new connection, the summary import lets you cut this down a little. Once logged in to the helper, choose the ?Summarise button: History (pg Tlmellne If; XKEYSCORE - Add?, gaph Add to Gra lmron as Query llama Statue Ouary Type llum P.r-.3u llum Datetima ?3 Classic inished 29.74 .3 013 3011-03-24 ..

TOP SECRET STRAP 1 To mirror the histogram grid performed on the data, I’ve chosen to include to_port: Note that when doing a summary import, summarisations will be done on source and destination IP in addition to any included fields. 2 of 6 TOP SECRET STRAP 1

TOPSECRETSTRAP1 Preferences for which fields to summarise by, whether you wish to summarise and whether you wish to automatically merge links between IP addresses and connections are saved per-user, so if you have a common histogram import then you don?t need to re-select the ?elds to histogram on every time. Data sourcing Data imported into Palantir using the updated XKEYSCORE helper now has data sourcing. There are a couple of places this can be seen, the most evident is the ?Data sources? application within Palantir.

The XKEYSCORE folder contains a list of the IP addresses and connection events associated with the query. Double clicking the document within this datasource opens up some metadata about the query run. 40f6 TOPSECRETSTRAP1
