Overview

Hack2Win is a hacking competition we launched 5 years ago. So far it had two flavors - Hack2Win Online and Hack2Win CodeBlue.

We decided to go big this year with Hack2Win eXtreme! Hack2Win eXtreme will focus on two primary targets, browsers and mobile.
We have up to $500,000 USD to give away, the competition will take place during the beVX conference Hong Kong, on September 20-21, 2018.

Prizes

Beyond Security is offering cash and prizes during the competition for vulnerabilities and exploitation techniques against the listed targets in the below categories.

If more than one contestant registers for a given category, the order of the contestants will be drawn at random.

Based on the participation order, the first contestant will be given an opportunity to attempt to compromise the selected target. If unsuccessful, the next randomly drawn contestant will be given an opportunity, and so on. This will continue until a contestant successfully compromises the target.

The first contestant to successfully compromise a selected target will win the prize money for that target in that category.

After a target has been compromised, the contest for that category will be over. Beyond Security may decide to continue the contest and offer an additional prize for that target, in which case this would be announced at the conference.

All prizes are in USD. 

Categories

  • Browsers
  • Mobile

Targets Devices

  • Android
    • On any of these devices: Pixel 2, Nexus 5X, Galaxy J7 and Galaxy S8 w/ latest available Android and security patch. The vulnerability needs to work on any of these 4 (four) devices. It is not a requirement for it to work on all 4 (four) devices.
  • iOS
    • iPhone X w/ latest iOS
  • Firefox RCE and Info Leak
    • Latest Firefox on latest Windows 10
  • Chrome RCE and SBE
    • Latest Chrome on latest Windows 10
  • Chrome SBE (Android/ Android Prize)
    • Latest Chrome on Pixel 2, Nexus 5X, Galaxy J7 and Galaxy S8 w/ latest available Android and security patch (vulnerability should preferably work on both devices)

Prizes per target

Browsers

  • Firefox
    • Infoleak - 30,000$
    • Remote Code Execution - 60,000$
  • Chrome
    • Sandbox Escape Windows - 80,000$
    • Sandbox Escape Android - 100,000$
    • Remote Code Execution - 80,000$

Mobile

  • Android
    • Privilege Escalation - 80,000$
    • Infoleak - 30,000$
  • iOS 
    • Privilege Escalation - 80,000$

Firefox Information Leak

A vulnerability would be regarded as an Information Leak if a code that leaks the full address of the following to a javascript variable:

  • Native thread stack
  • An address within xul.dll
  • The address of a heap allocation with fully controlled data

Lesser rewards may be awarded for leaks of address of other memory objects.

Integrity Level

For RCE vulnerabilities, executed code should run at the integrity level of the renderer process ('Tab') or higher.
 

Device Settings

  • The targets will be running on the latest, fully patched version of the operating system available on the selected target.
  • All targets will be installed in their default configurations.
  • The vulnerabilities utilized in the attack must be unknown, unpublished, and not previously reported to the vendor.
  • A given vulnerability may only be used once across all categories.
 

Remote Code Execution without Sandbox Escape

  • To provide a testing environment for this vulnerability, Chrome will be launched without the Sandbox feature chrome.exe --no-sandbox.
  • The URL of the researcher will be accessed - this URL needs to be reachable to the phone by having your laptop of USB key contain a payload that will be served by a web server (yours or provided by us).
  • Code will be executed due to the access of this URL.
  • This will be the only interaction allowed with Chrome (the URL placement and opening of it), any additional popup or question presented to the user will not be considered as RCE and will be considered a social engineering vulnerability and will not qualify as an RCE.
 

Remote Code Execution

  • Code execution would be considered as one when its arbitrary shell code execution.
  • The shell code should in assembly (either native or compiled code stored as assembly instructions).
  • The shell code should be running without any character, opcode, length or other restrictions. If any such restrictions exist, this should be noted during the demonstration of the code execution. The preferred shell code execution outcome would be popping of calc triggered by launching the executable.
 

Winner selection

Upon successful demonstration of the exploit, the contestant will provide a fully functioning exploit plus a whitepaper explaining the vulnerabilities and exploitation techniques used in the attack. Beyond Security will then determine whether the exploit meets the above rules. Beyond Security may choose to accept the entry(ies) but offer a prize at a value less than the initial prize offering for a given category if it decides that part of the exploit chain fails to meet the above rules.

A short white paper including details about all of the vulnerabilities (memory corruption, infoleaks, escalations, etc.) leveraged and the sequence in which they are used must be provided to receive the prizes.

Vulnerabilities and exploit techniques revealed by contest winners will be disclosed to the affected vendors and the exploits and whitepapers will be the property of Beyond Security. The original finder of the vulnerability will receive credit (or remain anonymous if he wishes to) for the vulnerabilities, the whitepaper and the disclosure.

NOTE: Beyond Security reserves the right to solely determine what constitutes a successful attack.
