Phishing for Postfinance (Part 2)

Posted by reto on 19 June, 2006 23:39

They are phishing for Postfinance logins again. And although the e-mail looks much nicer this time, they still have too many typos in it. ;-)
Another not so clever idea they had, was to use port 8081 for all their links, be it for the logo (yes, they didn't link it from the original site, but from their phishing server!) or the phishing URL ( [modified email domain]) itself. According to a whois query the ip range belongs to an ISP from tokyo:

Note that Thunderbird is doing well in the latest version and marks the mail as "Scam". This is handy for the less experienced users. Although it's probably too obvious this time.

Another effective detection of phishing mails can be done by using the information SpamAssassin provides in it's X-Header:
X-Spam-Status: No, score=4.3 required=7.0 tests=HTML_MESSAGE,
	RCVD_IN_NJABL_DUL autolearn=disabled version=3.1.0
Note the HTTPS_IP_MISMATCH which indicates that the shown URL ( does not match the linked one ([...]).
I'm already excited to spot the next fishhook!
