A sticker with a big QR code on it. In the center of the QR core is a white rectangle with "i386-unknown-linux" written on it. The QR code contains a 154B sized ELF binary.

A screenshot from Ghidra with some disassembled x86 Intel-style assembly code. The disassembly reads as follows: entry LEA ECX,[LAB_08049086] XOR dword ptr [ECX]=>LAB_08049086,0x5414070e XOR dword ptr [ECX + 0x4]=>LAB_08049087+3,0x550a1141 XOR dword ptr [ECX + 0x8]=>LAB_0804908d+1,0x1241010e XOR dword ptr [ECX + 0xc]=>LAB_0804908f+3,0x711491b XOR dword ptr [ECX + 0x10]=>LAB_08049096,0x466d4f03 ADD EBX,0x1 ADD EAX,0x4 ADD EDX,0x13 INT 0x80 SUB EAX,0x12 XOR EBX,EBX INT 0x80 LAB_08049086 PUSH EDI LAB_08049087+3 PUSH 0x63207461 OUTSD DX,ESI LAB_0804908d+1 JNZ LAB_080490fb LAB_0804908f+3 AND byte ptr FS:[EDI + 0x6f],AH AND byte ptr [EDI + 0x72],DH LAB_08049096 OUTSD DX,ESI OUTSB DX,ESI AAS

Hexdump of the binary. Next to the hexdump is a textual rendering of the binary, where we can see that the last 20 bytes of the binary are the string "What could go wrong?"
