We're releasing several pieces of scoring data today, ready to download and analyze as you see fit.
We've replayed all the redemption events from DEF CON CTF 2015 Finals into this YouTube video for your viewing pleasure.
Qualifiers Data Dump
Much like our 2014 data dump, this release includes JSON dumps of categories, challenges, notices, teams, and limited user information, and more importantly, offline-browsable HTML pages about teams, challenges, and more!
Download the DEF CON CTF 2015 Qualifiers data dump from https://files.legitbs.net/statdump_2015.tar.bz2, and verify its cryptographic signature using Vito's previously-published public key.
Finals SQL Dump
Want to get exhaustive detail about scoring in DEF CON CTF finals? This Postgres 9.4.1-compatible SQL dump file is what you want.
- Have PostgreSQL 9.4.1 or newer installed. 9.3 or older may work but has not been tested.
- OPTIONAL: verify that you downloaded an official dump. More instructions below.
Create a database named
scorebot-2015. From the command line:
Load the pgdump file into the database:
pg_restore -d scorebot-2015 scorebot-2015.pgdump
> psql scorebot-2015 psql (9.4.3) Type "help" for help. scorebot-2014=# select id, name, dupe_ctr from teams order by name asc; id | name | dupe_ctr ----+-------------------------------+---------- 9 | !SpamAndHex | 0 12 | 0daysober | 2289 11 | 0ops | 0 6 | 9447 | 1549 2 | Bushwhackers | 0 10 | CORNDUMP | 0 5 | DEFKOR | 11 13 | Dragon Sector | 4 7 | Gallopsled | 0 4 | HITCON | 0 15 | LC↯BC | 1 16 | Legitimate Business Syndicate | 0 1 | Plaid Parliament of Pwning | 18441 3 | Samurai | 0 14 | Shellphish | 0 8 | blue-lotus | 0 (16 rows)
Validating and Verifying These Dumps
Once you've downloaded the dump files, you can check its signature against Vito's public GPG key.
- Obtain Vito's public key from this blog, Keybase.io, or the MIT Public Key Server .
- Install the key in your GPG keychain.
gpg --verify scorebot-2015.pgdump.sig. You should see output similar to:
> gpg --verify scorebot-2015.pgdump.sig gpg: assuming signed data in 'scorebot-2015.pgdump' gpg: Signature made Fri Aug 28 20:04:57 2015 EDT using RSA key ID C81CA674 gpg: Good signature from "Vito Genovese
