A new phishing campaign is sending thousands of ominous-looking emails that contain the recipient's home address. The well-worded email appears to come from a legitimate email address and domain name, and raises very few irregularities. The email comes with an demand for money for an arbitrary service, along with a link that purports to be an "overdue invoice." Click that link and open the file (which looks like a Word document), and you'll become the latest victim of ransomware -- that is, malware that encrypts your files and locks you out of your computer until you pay a ransom. The longer you wait, the larger the ransom you have to pay.
