For example, even if Dropbox gives you the option of blocking document modification, you can still download and modify confidential files on your hardware and then upload them to the server. It can therefore be assumed that from the technological side, files on Dropbox are safe, with the proviso that due to the purpose of Dropbox, which is storing and sharing prevalently non-critical information, the service does not have some key functions many dedicated solutions for comprehensively secure storage of classified information might have.

However, such attacks do not happen every day, and the awareness of phishing is constantly being raised. Suffice it to say that the infamous attack of 2013 was based on hacking into the account of an employee who, horror of horror, used the same login password in other places on the Internet, and criminals managed to guess it. This is also unlikely but not impossible.

If – which is rather certain, but we cannot completely exclude it – we are not dealing with a dishonest Dropbox employee who theoretically has access to our data, the criminal would have to somehow intercept the encryption key or gain access to an employee account or key database to be able to read the encrypted file. In practice, this is a high class security.
