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

I was shocked—to say the least. So that’s why this whole thing felt so strange from the very start! I did my best to keep a straight face—mostly because the Chief was there.

—So—Chief stammered—he was normal at first, and then something happened to him… Can you tell where exactly?

—I’d have said yes back in the day. But… I’m not so sure Earth’s digital forensics works on aliens!

—Come on—fire up your Belkasoft.
