[WEB SECURITY] program to crawl website looking for string patterns

FuzzDB has a set of regex patterns
for the docs and set of test cases, respectively
Depending on your purpose and the value of depth and completeness to
your test, as well as the structure of the sites to be evaluated
themselves, you may not want to entirely rely on an automated crawler.
Many websites have entire sections that automated web crawlers can
never reach. The crawler may also not handle authenticated session
state well, without some effort. Solution: If depth is critical, make
sure to do a manual crawl, as well. You can load the PII regex
patterns into something like Burp, in order to monitor the traffic
passively for them. Then just have your automated spider tools also
run through burp. You may want to have Burp log the full request and
response to a file, for later, deeper analysis.
One thing you want to do post-crawl analysis for is that there may be
PII in the results, encoded in a way which your regex would miss.
Examples: SSN in URL encoding, base-64 encoded, unicode encoded, etc.
Sounds like an interesting project. Good luck!
