DEADROP Rev 3 - asset_tracker
A Windows PE with two anti-debug gates, IsDebuggerPresent and PEB NtGlobalFlag, protecting XOR-encoded flag fragments in .rodata. Patch or bypass the checks, then decode the three fragments with their respective keys.

DEADROP Rev 1 - agent_verify
A Linux ELF binary that XOR-encodes the correct passphrase in .rodata. The flag is the passphrase itself, ltrace -s 200 hands it to you directly via strcmp interception.
