FTK is particularly effective at cracking passwords for which file types?

• A. Image files
• B. PDF files and Excel spreadsheets
• C. Audio files
• D. Plain text files

Answer: (B)

The main idea is that password cracking effectiveness depends on how a file type protects its content. PDF files and Microsoft Office documents like Excel use password-based encryption with well-defined key derivation and verification steps. FTK’s recovery capabilities are optimized to tackle these formats, testing candidate passwords and quickly checking whether they unlock the document. Because the encryption and key-derivation process for PDFs and Office files is structured and widely documented, FTK can apply efficient, format-specific attacks to recover passwords faster than it can for other types. Image files, audio files, or plain text files aren’t typically protected by strong, standard password encryption, or they aren’t protected at all. When there isn’t robust protection to crack, there isn’t the same opportunity for a specialized, fast password-cracking path, so those formats aren’t where FTK concentrates its password-recovery effort.
