Blazorized in a Windows-focused box, starting with a website written using the Blazor .NET framework. I’ll reverse a DLL that comes from the server to the browser to find a JWT secret and use it to get access to the admin panel. There I’ll abuse SQL injection to get execution and a shell. To pivot to the next user, I’ll abuse the WriteSPN privilege to perform a targeted Kerberoast attack. Then I’ll abuse permissions to write another user’s login script. Finally, I’ll abuse the Get...| 0xdf hacks stuff
It recently came to my attention that John McAfee has been advertising a cryptocurrency hardware wallet from a company called Bitfi, with the claim that it is “unhackable”. There’s even a…| rya.nc
Appsanity starts with two websites that share a JWT secret, and thus I can get a cookie from one and use it on the other. On the first, I’ll register an account, and abuse a hidden input vulnerability to get evelated privilieges as a doctor role. Then I’ll use that cookie on the other site to get access, where I find a serverside request forgery, as well as a way to upload PDFs. I’ll bypass a filter to upload a webshell, and use the SSRF to reach the internal management page and trigger...| 0xdf hacks stuff
The hard challenges really took it up a level. My favorite was a .NET web application where I have to crack a licence key. There’s also finding and reversing a backdoored passwd binary, some binary exploitation where I have to crash the server to preserve the flag and read it from the dump, RSA via an image, USB forensics, and exploiting a Minecraft server with Log4Shell.| 0xdf hacks stuff
Coder starts with an SMB server that has a DotNet executable used to encrypt things, and an encrypted file. I’ll reverse engineer the executable and find a flaw that allows me to decrypt the file, providing a KeePass DB and file. I’ll use the file as a key to get in, and find the domain, creds, and a 2FA backup to a TeamCity server. I’ll reverse the Chrome plugin to understand how the backup works, and brute force the password to recover the TOTP seed. With that and the creds, I can log...| 0xdf hacks stuff
