📄 BelkaCTF #4: “Kidnapper Case” write-up

—They called me again. Twice, — It looked like the Chief was angry at me because of that.

—Are you saying I work too slow? Or should I take these calls on your behalf?

The Chief missed my words, he seemed to be looking for his cigarettes.

—Look, Chief, I found something interesting. The boy was selling their goods under the counter.

The Chief stopped the search.

—You said what? And did his supervisor…

The Chief did not complete the sentence. We looked at each other knowingly.

Q: What was the other BTC wallet of the victim, which he used to hide his "under the counter" sales from his superior?
