One attack uses an attached file, often a .zip file, to introduce harmful software into your computer that can cause immediate damage or work in the background quietly sending copies of important files you keep to The Bad Guys. These can include your Quicken (or other financial) files and Outlook Contact lists just to name two. Immediate damage can include loss of files and/or damage to your operating system potentially leaving your PC as an expensive lightweight "boat anchor". The Bad Guys may play for fun and games, they may play for profit but most times it is for keeps at your expense at some level.
For Toll Charges:
As states are moving toll road operations and management to third parties, we are seeing fewer and fewer staffed toll booths to collect fees. This has created a "new business opportunity" for The Bad Guys to leverage the potential confusion into people taking action to inflict damage to computers or solicit expedited payments. Those observed as of July 2015 are focused in the infliction of damage.
