The "flag" is usually the final prize, often formatted as FLAG{...} or CTF{...} . In some forensics challenges, the flag may be hidden in the ZIP's or within alternative data streams (ADS) if the file was handled on a Windows system.

Depending on what was found in the archive, use these specialized techniques:

: Run strings on the zip and any extracted binaries. Look for readable text, URLs, or base64-encoded strings that might be the flag. File: Space.Invaders.Extreme.zip ...

Image files ( .png , .jpg ) that might contain steganographic data.

: Use these tools to see if other files are embedded inside the extracted files. For example, a PNG file might actually have a ZIP appended to the end of it. The "flag" is usually the final prize, often

: If the archive is password-protected, tools like John the Ripper or hashcat are used to crack the ZIP password using wordlists like rockyou.txt . 3. Deep Analysis Techniques

: If an executable is present, load it into Ghidra or IDA Pro . Analyze the logic—specifically where it handles input or "victory" conditions—to find where the flag is generated or stored in memory. 4. Extracting the Flag Look for readable text, URLs, or base64-encoded strings

: Run unzip -l Space.Invaders.Extreme.zip . Common contents might include: An executable ( .exe or ELF) related to the game.
