PACTF is an online computer security competition primarily for high school students, organized and run by students at Phillips Academy in Andover, MA, U.S.A. We plan to offer more than $20,000 in prizes.

PACTF will run from April 16–April 30. There will be two rounds, each one week long. During each round, your team can pick any two-day span to solve as many problems as you can. Rounds will feature binary exploitation and reversing, cryptography, and other miscellaneous topics, with introductory and advanced problems in each category.

Our sponsors include Amazon, DigitalOcean, J.P. Morgan, ProtonMail, CyLab @ CMU, INI @ CMU, and the Tang Institute @ Phillips Academy Andover.

PACTF 2018 will be PACTF's third competition. Prior competitions can be viewed at and For more information about the competition, see
