Hey, RuCTFE will start at this Saturday! We've updated router and test images and sent to PoC of teams credentials for VPN, checksystem and RuCTFE Cloud access, please check your email (also check "Spam" folder!). If you haven't received the letter, you can request it again.

This year we have two huge changes in rules and network behavior:
1. Now you will have access only to HTTP flag submission systems. Here is an example of HTTP-version usage. Yep, no TCP at 31337 port since this year.
2. We've shuffled your IDs. Not accidentally, it's our choice. Now your ID for the game is not placed on Teams page, you'll get it with your configs.

And one small change: we’re moving from IRC to Slack.

Some important instructions!
If you plan to run vulnbox on your own server: download Router and TestImage and follow the instructions.
If you plan to play from Cloud: just chill, Cloud will be opened with the game start (you'll have enough time to prepare VM).
If you do/don't like changes: turn and face the strange changes and send your feedback to us 🙂

This year we’ve shuffled teams’ IDs and will not show IPs on scoreboard. It’ll makes game harder for pros and changes nothing for newbies. Teams' IDs are pre-shuffled from 1 to 699 and we have full mapping, that will be shared after end of the game. During the game it's only up to teams to share or not share their ID/IP.

Question from WE_0WN_Y0U team: So since the IDs are randomized, can we somehow query which IDs are actually online/assigned? Cause otherwise we'd have to scan the net/attack the full range of possible IPs?
Answer: Yes, we’ll post the list of registered IPs right after registration closing on Slack, Telegram and on RuCTFE.org.

While devs are having last preparations, we've collected some questions from you. Here is the answers.

Q: If my team plays self-hosted, what's system requirements?
A: Nothing special, 2 CPUs, 4GB RAM, 30GB HDD will be okay. Remember to install VirtualBox 6.0.14!

Q: Remind me, how long game round and flag lifetime is?
A: One round takes nearly 1 minute, flag is actual for 15 rounds.

Q: So, what's the timeline?
A: Get image password or access to Cloud at 10:00UTC, prepare for network opening at 11:00UTC, attack and defence for 8 hours. Celebrate winning at 19:00UTC!

And while you’re waiting for game start, we want to wish a happy belated birthday to Znick, one of the RuCTFE creators and first network master! Congratulations!

Let's go! Password for image is 9w2hJ25jBvZNgPXrDX3AVGNh6hPbUg6k, Cloud is open. Network will be closed for the first hour. Wish you good luck and having fun!

Network will be opened in 5 minutes!
Remeber to run connect_vm_to_game_network if you’re using Cloud.
Scoreboard is available at monitor.ructfe.org (monitor.ructfe.org/board for oldfags)
If you have problems with self-hosting, you’re welcome to use Cloud.RuCTFE.org! There is ~70 free slots now.

Congratulations, @fargate_team!

Oh, it’s fast

And another one!

5/7 firstbloods

6/7! Last one left

Oops, there was wrong logo. Sorry, werelaxe, I’ve fixed it 🙂

Last firstblood (but we don’t think that enigine was really hacked….)

Guys, this year we’re having noticeably more traffic than last year. Please, try not to run exploits every round. Running it every 5 rounds you’ll lose nothing, but it’ll unload network!

The more you're flooding, the less priority you'll get 🙂

The current top 10 teams by bandwidth are:
1. Shadow Servants
2. Enoflag
3. STT
4. Tower of Hanoi
5. [SPbCTF] Kappa
6. C4T BuT S4D
7. [SPbCTF] fargate
8. Bushwhackers
9. CatchFM
10. BinaryBears

The "too much" is about >10 mbits/sec
