The following incident occurred to the city of Riveria Beach, Florida very recently after one of it’s employees opened a suspicious email that contained ransomware.
It cost them $600,000 and then some.
It is of paramount importance that when receiving / opening email you perform due diligence before clicking to open the email or opening attachments, take a look at the “from” address, if the email address doesn’t match the content of the email you are receiving it should be an immediate red flag. Look for broken English and poorly constructed sentence structure or faulty logic that would seem out of character for the expected sender. People can spoof email account addresses and construct email to look legit, you as a user have to take every action you can to verify before you open, you CAN NOT just say “oh there’s antivirus” or “oh it’ll be fine I don’t have to worry about it”…..your a/v may be out of date or it may be a brand new variant of a virus that the major a/v manufacturers have not yet classified for protection.
The first line of defense for you as an individual or at your workplace is you. These ransomware attacks that encrypt data and charge for it’s release are dramatically increasing, the article referenced in this post depicts many other victims and there are many others that do not report.
