Cracking Legacy ZIP Encryption: The Known-Plaintext Attack and Why It Still Sometimes Works
July 20th, 2026 by Oleg Afonin
When someone hands you a password-protected ZIP archive, one’s immediate thought is “I need to break the password”. For most modern archives, that is exactly the case, and the password is the whole game. But there is a family of ZIP archives where the password does not matter at all. It can be four characters or forty, random or memorable; if the archive uses the legacy ZIP encryption, the whole thing can be unlocked in minutes without ever guessing the password. This is one of the oldest tricks in our line of work, and it is worth telling the story properly, because it is equal parts computer history and practical forensics.

Protecting one’s online privacy is becoming increasingly more important.

Breaking VeraCrypt: Obtaining and Extracting On-The-Fly Encryption Keys
June 3rd, 2021 by Oleg Afonin
Released back in 2013, VeraCrypt picks up where TrueCrypt left off. Supporting more encryption algorithms, more hash functions and a variable number of hash iterations, VeraCrypt is the default choice for the security conscious. VeraCrypt has no known weaknesses except one: once the encrypted disk is mounted, the symmetric, on-the-fly encryption key must be kept in the computer’s RAM in order to read and write encrypted data. A recent change in VeraCrypt made OTF key extraction harder, while the latest update to Elcomsoft Forensic Disk Decryptor attempts to counter the effect of the change. Who is going to win this round?
