09 FAQ

Questions

Something else? [email protected]

Do I need to work in security to come?

No. Students, people learning and people already in the field are all welcome. Some talks get technical, so ask questions.

Is everything in English?

Talks are in English. Hallway and village chats happen in whatever mix of English and Hindi works.

What should I bring?

A laptop and charger for hands-on sessions, and a warm layer for the evening. Talks need no laptop.

Can a sponsor buy a talk slot?

No. Sponsorship never buys a talk, workshop, panel, village slot or CTF advantage.

Why "0x03"?

It is three in hexadecimal. Third edition.
