OT: web-based applications and security...

[Modulok]

This is completely off topic, (as indicated in the subject line):

Is it just me being paranoid, or is all this 'online' and 'live'  aka
web-based applications and data storage like... the biggest security
threat in the Universe? Not only from the perspective of the company
offering said services selling you out, but also in the fact that it
creates a high-value target (tons of data in one place) for the entire
world to try and exploit.

Thoughts?
