We recommend checking the downloaded files with any free antivirus.
From the developer:
Bait is a security application keeping track of who tries to log into your computer while you are away. When you lock your computer and walk away, Bait keeps an eye out on your behalf. Whenever someone tries to unlock your computer, Bait will create a snapshot of the person doing so and report back to you upon your return.
You may want to check out more software for Mac, such as ESET NOD32 Antivirus Business Edition, SSH Helper or DRPU Mac Log Manager, which might be related to Bait.
