Ransomware --- We had a case of ransomware at the public institution I work for. We were hosting an event and asked the guests to confirm their attendance by email, as there were going to be sitting arrangements. One of our staff was in charge of confirmations and she opened an attachment from a trusted source. Unfortunately, the attachment was corrupted with a virus that hijacked the official email account and we lost thousands of sent and received emails, some of them with confidential information.
