Jun 25, 2018 · HackTheBox.eu (online, free, optional VIP subscription) Registration on HackTheBox requires you to ‘hack’ your way in. It is a simple task. If you find yourself unable to get the invite code by yourself, you will have a very hard time solving their challenges and hacking their boxes. Learn some more then try again. A simple way is to specify -t: ssh -t remotehost "sudo ./binary". From the man page: Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services. Multiple -t options force tty allocation, even if ssh has no local tty. Summary Forwardslash,a Linux box created by HackTheBox user InfoSecJack and chivato, was an overall hard difficulty box.The Initial foothold was finding the SSRF on porfilepicture.php in backup.forwardslash.htb and that expose the creds for chiv. hackthebox; sql; phantomjs; logrotten; linux; ssh; Configuration. The operating systems that I will be using to tackle this machine is a Kali Linux VM and a Windows Commando VM. What I learnt from other writeups is that it was a good habit to map a domain name to the machine's IP address so as that it will be easier to remember.
