This commit fixes numerous CI build issues related to stale or broken
links. These include:
* Removal of Zoom username enumeration tool, covered by WPScan anyway.
* Removal of old Google dork database that is unmaintained/has vanished.
* Removal of `OSVDB.org` zone, which no longer resolves via DNS.
* Fix link to NoSQLmap tool (domain expired, use GitHub.com link now).
* Update link to Social Engineering in IT book from legacy URL.
* Update link to OWASP's AppSecUSA conference; now uses second-level domain.
Further, this commit simplifies the `.travis.yml` file in order to use a
plainer (more standard) certificates bundle. Two URLs have been added to
the whitelist: `www.shodan.io`, which returns a 403 Forbidden error when
accessed by Awesome Bot, and `www.mhprofessional.com`, which generates
an SSLv3 certificate validation error.
Prior to this commit, a custom SSL certificate bundle was generated and
then placed in the `/tmp` directory for use, but this is no longer
required as the latest `ca-certificates` bundle shipped with Ubuntu
contains the root certificates needed for the domains that once required
this custom bundle to be used.
* Add CVE List to Vulnerability Databases section, since it was missing.
* Style guide compliance pass focused on Vulnerability Databases section.
* Whitelist the Inj3ct0r URLs.
The `0day.today` website sits behind an extremely aggressive Cloudflare
anti-bot checker, which causes `awesome-bot` to trigger an HTTP 503
response. This fails the build but is actually normal behavior.
Similarly, the Onion service is inaccessible except over Tor and our
Travis CI configuration does not (yet?) support checking Onion service
links. (Although, perhaps it should be updated to do so in a future PR.)
