đź“„ BelkaCTF #7: Stranger Dfings write-up

I kept pushing on my own, taking the risk without telling the Chief just yet. I felt like I was this close to cracking this whole bizarre mess wide open. I had the radar serials—maybe, just maybe, I could get even further.

Suddenly, it clicked. That VPN config transferred inside the Wi-Fi capture I decrypted. The comment line about the password was annoyingly cryptic and clear at the same time: “the identification number of our spacecraft.”

My brain sparked with an image from earlier—one of those dark-shades guys hunched over his laptop. I’d managed a sneaky shoulder-surf and spotted the URL: https://spysatarchive.nsa.fyi/.

If only I had the exact timestamp and GPS coordinates of that damn UFO blip from ATC radar terminal—I could retrieve a sat image and nail that spacecraft’s hull number.
