If you found a known plaintext (like a common header), describe how you used a to recover the internal keys without a password.

Use the file command in Linux to confirm it is a true ZIP archive.

If the file is password-protected, note if it uses standard ZipCrypto or AES-256. This determines which tools (like bkcrack for ZipCrypto or John the Ripper for AES) are necessary. 3. Methodology & Exploitation rakhi_OFpcvd_luciferzip

(e.g., Forensics, Reverse Engineering, Cryptography) Difficulty: (e.g., Easy/Medium/Hard)

List any clues from the challenge description that you tried as passwords. If you found a known plaintext (like a

Provide the MD5 or SHA256 hash to ensure others can verify they have the same file.

If the name "lucifer" refers to the old , explain how that influenced your decryption strategy. 4. Solution & Flag This determines which tools (like bkcrack for ZipCrypto

Briefly mention a "gotcha" or a new tool you learned while solving this, such as identifying specific encryption streams.
