Access is an "easy" difficulty machine, that highlights how machines associated with the physical security of an environment may not themselves be secure. Also highlighted is how accessible FTP/file shares can often lead to getting a foothold or lateral movement. It teaches techniques for identifying and exploiting saved credentials.

That discrepancy bothered me, so I spent an evening working through the network stack on my Arch Linux machine to figure out where the bottleneck actually lived and what I could tune locally. The first lesson was that single-stream HTTP tests against ...

A simple script to discover the maximum MTU supported by every device on your LAN — so you can confidently enable jumbo frames without breaking connectivity. Why Most home and lab networks run at the default MTU of 1500 bytes. But if your switch and NICs support jumbo frames (up to 9000 bytes), you’re leaving throughput on the table — especially for large file transfers, NAS backups, and VM t...

A lightweight, real-time download scanner that quarantines new files in ~/Downloads, checks their SHA256 hash against VirusTotal, and only releases them once verified clean. Why Every file you download is a potential threat. Browsers don’t verify file reputation beyond basic Safe Browsing checks. VT Watcher adds a second layer — every file that lands in your Downloads folder is automatically ...
