Meaning of sneaky

[Rich7]

I found that one of the definitions of this word reads:
marked by quiet and caution and secrecy, taking pains to avoid being obseve.

In this description, what the underlined expression means?

[Torsten]

To take pains means to try very hard to achieve something. Going to great lengths might be similar to taking pains.
Please mind that you definition should read ... being observed.
