Re: Details on AOL search log disclosure

They must have a more selective regex than mine.  I got 260 hits.   
Selecting those results which also contain the word 'social' results  
in 22 hits, with many that are clearly attempts to look up the  
records of a specific individual -- often supplying an address  and  
DOB as well as an SSN.

The regex I used is:

/(?!000)([0-6]\d{2}|7([0-6]\d|7[012]))([ -]+?)(?!00)\d\d\3(?!0000)\d{4}/

It is a minor variant of one found at http://www.regexlib.com/ 
REDetails.aspx?regexp_id=535

(Checking for CC#s now....)
