Hi,
 I'm trying and failing to understand the debug output for a positive phishing 
check result coming from a legitimate email from a bank.

If I do a scan with the debug flag I get the following -

LibClamAV debug: Looking up in regex_list: www.hsbc.co.uk/
LibClamAV debug: calc_pos_with_skip: skip:16, 8 - 22 
"https://www.hsbc.co.uk","www.hsbc.co.uk/";
LibClamAV debug: calc_pos_with_skip:
LibClamAV debug: calc_pos_with_skip: skip:4, 8 - 22 
"https://www.hsbc.co.uk","www.hsbc.co.uk/";
LibClamAV debug: calc_pos_with_skip:hsbc.co.uk
LibClamAV debug: Got a match: www.hsbc.co.uk/ with /ku.oc.cbsh
LibClamAV debug: Before inserting .: .www.hsbc.co.uk
LibClamAV debug: Lookup result: in regex list
LibClamAV debug: Phishcheck: Phishing scan result: URLs are way too different


I understand what the Heuristics.Phishing.Email.SpoofedDomain is checking for 
and understand that most "false positives" aren't actually false positives when 
someone sends a HTML email with a HREF link target differing from a URL entered 
as the link text.

But with the above debug output I can't understand what it is trying to tell 
me. I don't see a 'false' URL being compared against.

If I look through the HTML email message for 'hsbc' I also don't see any HTML 
that uses a URL as the visible text.

Does anyone know what these two lines mean?

LibClamAV debug: Got a match: www.hsbc.co.uk/ with /ku.oc.cbsh
LibClamAV debug: Before inserting .: .www.hsbc.co.uk

Regards
Mickey Williams
