Explain why brute-forcing modern AES-encrypted ZIPs is computationally expensive and depends entirely on password entropy. 3. Theoretical Performance & Hardware Acceleration

Contextualize ZIP security: Evolution from legacy ZIP 2.0 encryption (vulnerable to known-plaintext attacks) to modern AES-256 encryption.

Differentiate between legal password recovery (regaining access to your own data) and unauthorized access. 5. Countermeasures & Best Practices

Compare CPU vs. GPU brute-forcing: Tools like Hashcat use GPU parallelization to test millions of combinations per second.

Many sites offering "hacker tools" or "cracked" ZIP recovery software bundle Trojans or spyware.

Mention the use of key derivation functions like PBKDF2 to slow down hashing attempts.
