That eagerness to help out a coworker with a problem is, on the one hand, part of what greases the wheels of industry, and part of what makes the employees of some companies more pleasant to work with than employees of others. But on the other hand, this helpfulness can be a major vulnerability that a social engineer will attempt to exploit.
