Meaning of sneaky

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?

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 [color=blue]observed.[YSaerTTEW443543]

Ok, it makes sense to me quite a bit, good point that of the verb in past participle, my bad.
