Worth Reading: Good Samaritans with network visibility

In a big open office 30 feet from me, a team of US Veterans speak intently on the phone to businesses large and small, issuing urgent warnings of specific cyber security threats. They call to get stubborn, confused people to take down hidden ransomware distribution sites. They call with bad news that a specific computer at the business has malware that steals login credentials. They call with good news — you can beat the bad guys this time by not sending the money — minutes before an email arrives to the business with fraudulent wire transfer instructions. —CircleID
