A very clever phishing campaign targets bloggers and website owners with emails pretending to be from their hosting provider who wants to upgrade their domain to use secure DNS (DNSSEC).

As it's possible to determine who is hosting a domain for a website via the WHOIS records, IP addresses, and HTTP headers, the email scam is highly targeted and impersonates the specific hosting company used by a website.
