Challenge 1

As we prepare for the beVX conference, we'll make a few online challenges available. Those who solve them (quickly enough) will get free entry tickets, flight and accommodations to the event.

 

Rules

  1. The only entry point to the challenge is via SSH. Do not attempt to break-in through any other way or method to the server – this will get you disqualified. Also, please do not port scan, run a vulnerability scan, penetration test, DoS, or other intrusive tests on the IP address or any other system in that subnet; this will get you disqualified and may get you into trouble since the server is hosted in a shared network environment.

  2. After you SSH in, you will be presented with a screen with several options. The challenge is solvable using a combination of Reverse Engineering (of the file below) and the SSH access.

  3. Once you have solved the challenge, email your full solution to ssd@beyondsecurity.com – the solution should include both the encryption key and the program that extracts it.

 

Prizes

  1. First place winner will get a round trip to Hong Kong (Coach), Hotel Accommodation and an entry ticket to beVX Conference in September (valued at 3,000$ USD)
  2. Second place winner will get a round trip to Hong Kong and an entry ticket to beVX Conference in September (valued at 2,000$ USD)
  3. Third place winner will get an entry ticket to beVX Conference in September (valued at 1,000$ USD)

 

Enjoy the challenge!
