Phishing by Phax
The most fascinating phishing message in a long time is aimed at Barclays' customers. It's remarkable for moving away from fake web pages: Instead, it squats on UK area code 870 phone numbers used by Barclays' by trying to convince recipients to fax a ton of personal information to a country code 870 phone number -- an Inmarsat fax number, it seems. The difference that you can spot is a single digit 0 more in front of the fax number.
The fax form itself includes bullet points with good advice on how to avoid web-based phishing attacks.
