Hacking Passwords for People
Password History: In older versions of MS Excel and Word, passwords were stored as plain text in the document header information, allowing anyone who viewed the header to read the password. This was the case for all versions older than Office 2000. Similarly, Windows once stored passwords as plain text in a hidden file, meaning that one could simply delete the file to erase the password.
In the early days, both Microsoft and Adobe used passwords to indicate that a file was password-protected when opened with their respective applications. However, if the file was opened with a different application, such as Notepad, the password was not necessary. Moreover, Microsoft Access 2.0 databases could be easily opened as a text file by simply renaming them with a ".txt" extension, enabling users to view the database data.
Furthermore, Adobe PDF files in versions 4.0 and older were often printable and viewable using Linux PDF readers or Ghostview for Windows, regardless of any password protection.
Wireless networks have also faced encryption-related issues, as the encryption key can be guessed once enough encrypted data has been collected from the air to identify patterns and deduce the keys. With the computing power available in modern homes, these keys can be cracked almost instantly, revealing the password.
Bluetooth security, on the other hand, is generally considered quite secure once it has been set up. The problem lies in the way Bluetooth establishes a connection. During this process, a unique, freshly generated password is transmitted between the devices in plain text. If this password is intercepted, all future transmissions for that session can be easily decoded.
Overall, these examples illustrate the evolving nature of password security and the various vulnerabilities that have been present in different technologies over time. As computing power and data collection methods have advanced, the importance of robust and secure password practices has become increasingly crucial to protect sensitive information.
