Hi. We're going to shut down our servers which were kept online for contestants to check their answers and publish write-ups. #tkbctf4

[tkbctf @tkbctf]

#tkbctf4 is over! Here's the TOP-10 chart. http://t.co/C8gpjDcBWJ

CTFは終了しましたが、あと数日問題サーバは起動したままにします。Write-upの執筆や模範解答の確認等にお役立てください。 #tkbctf4

[tkbctf @tkbctf]

We're going to keep hosting the target servers for another day or two. This shall help you testing the correct answers on writeups. #tkbctf4
