wargame/bandit 썸네일형 리스트형 Level 25 → Level 26 Level Goal Logging in to bandit26 from bandit25 should be fairly easy… The shell for user bandit26 is not /bin/bash, but something else. Find out what it is, how it works and how to break out of it. bandit25에서 bandit26에 로그인하는 것은 꽤나 쉬울 것이다... 사용자 bandit26을 위한 쉘은 /bin/bash가 아니라 다른 것이다. 무엇인지 찾고 어떻게 작동하는지 어떻게 부수는지 발견하여라 Code bandit25@bandit:~$ ls bandit26.sshkey bandit25@bandit:~$ cat bandit26.sshke.. Level 24 → Level 25 Level Goal A daemon is listening on port 30002 and will give you the password for bandit25 if given the password for bandit24 and a secret numeric 4-digit pincode. There is no way to retrieve the pincode except by going through all of the 10000 combinations, called brute-forcing. 데몬은 포트 30002에서 대기하고 있으며 만약 bandit24의 비밀번호와 4자리의 pincode를 제공하면 bandit25의 비밀번호를 제공할 것이다. brute-forcing이라고 불리는 10000개의 모.. Level 23 → Level 24 Level Goal A program is running automatically at regular intervals from cron, the time-based job scheduler. Look in /etc/cron.d/ for the configuration and see what command is being executed. NOTE: This level requires you to create your own first shell-script. This is a very big step and you should be proud of yourself when you beat this levell! NOTE 2: Keep in mind that your shell script is remo.. Level 22 → Level 23 Level Goal A program is running automatically at regular intervals from cron, the time-based job scheduler. Look in /etc/cron.d/ for the configuration and see what command is being executed. NOTE: Looking at shell scripts written by other people is a very useful skill. The script for this level is intentionally made easy to read. If you are having problems understanding what it does, try executi.. Level 21 → Level 22 Level Goal A program is running automatically at regular intervals from cron, the time-based job scheduler. Look in /etc/cron.d/ for the configuration and see what command is being executed. 프로그램은 (시간에 기반을 둔 job scheduler인) cron에서 일정한 시간 간격을 두고 자동적으로 실행된다. /etc/cron.d/에서 구성을 찾고 어떤 명령어가 실행되는지 확인하여라 Code bandit21@bandit:~$ cd /etc/cron.d/ #디렉토리 이동 bandit21@bandit:/etc/cron.d$ ls cronjob_bandit22 c.. Level 20 → Level 21 Level Goal There is a setuid binary in the homedirectory that does the following: it makes a connection to localhost on the port you specify as a commandline argument. It then reads a line of text from the connection and compares it to the password in the previous level (bandit20). If the password is correct, it will transmit the password for the next level (bandit21). NOTE: Try connecting to yo.. Level 19 → Level 20 Level Goal To gain access to the next level, you should use the setuid binary in the homedirectory. Execute it without arguments to find out how to use it. The password for this level can be found in the usual place (/etc/bandit_pass), after you have used the setuid binary. 다음 단계에 접근하기 위해서, 홈 디렉토리에 있는 setuid binary를 사용해야 한다. 어떻게 쓰는지 알아내기 위하여 인수 없이 실행해라. 이 단계의 비밀번호는 setuid binary를 사용한 후, usual pl.. Level 18 → Level 19 Level Goal The password for the next level is stored in a file readme in the homedirectory. Unfortunately, someone has modified .bashrc to log you out when you log in with SSH. 비밀번호는 홈 디렉토리에 있는 readme 파일에 저장되어 있다. 불행하게도, 누군가가 당신이 ssh로 로그인 할 때 당신을 로그아웃하도록 .bashrc를 수정했다 Code kjs@virtualbox:~$ ssh bandit18@bandit.labs.overthewire.org -p 2220 'cat readme' This is a OverTheWire game server.
