Coronavirus-related social distancing measures have given a big popularity boost to Zoom, a video conferencing platform that's known for its ease of use but not necessarily strong security or privacy protections. Internet trolls and other troublemakers have responded with "Zoombombing": joining Zoom meetings uninvited and disrupting them. Zoombombers have exposed themselves to schoolchildren and shouted racial slurs.

In a Friday statement, federal prosecutors in Michigan warned the public that Zoombombing isn't a harmless prank; it's a crime.
