In addition to solar and wind stations, everyone around the world is actively building Smart Grids allowing effective energy use.

Review of Hash Runner Tasks

Intro

This year, Hashrunner had been taking place during three days before Positive Hack Days — from May, 16 19:00 (UTC+4, Moscow) till May, 19 19:00 (UTC+4, Moscow). Among other matters, we were trying to respect the interests of all geographically dispersed teams and cover 48 hours of two weekend days for every time zone. We received great positive feedback about including the whole weekend and thus we’ll try to keep it this way.

Congratulations to the winners!

  1. InsidePro with 22.81% (write-up) won two R290x video cards plus souvenirs.
  2. hashcat with 21.23% (write-up) won an R290x video card plus souvenirs.
  3. john-users with 12.78% (write-up) won souvenirs.

Within three years of the contest, we had three unique winners: hashcat in 2012, john-users in 2013, and InsidePro in 2014. Every year, most submissions were received in the last 15 minutes and thus the winner was determined in the very nick of time. In 2012 and 2013, InsidePro was beaten into the second place by hashcat and john-users, respectively. This year, InsidePro finally became the first.

Review of WAF Bypass Tasks

This year, the visitors of the Positive Hack Days Forum were invited to have a shot at bypassing the PT Application Firewall in the contest called WAF Bypass. It was a good opportunity for us to test our product in action, because the forum gathered the best information security experts. We had prepared a set of tasks for the contest, each representing a script with a typical vulnerability.

The participants were invited to use these vulnerabilities to get flags.  All tasks were solvable, though some solutions were not obvious. The contestants were provided with the report about scanning the tasks' source code with another Positive Technologies product Application Inspector. In this article, we will consider the contest tasks, bypassing methods, and the experience we have obtained.
