Google Searched Queries

In the continuation of the topic of requests that search engines do not cope with (or these requests are specially filtered). Last time, Bing, who did not quite successfully try to block bots, turned out to be in the spotlight, as a result of which some requests from a client who did not have Bing cookies returned an error .

Now they found a “hole” in Google: for example, such a request [9999999..99999999999999999999999] is blocked by Google. Instead of nines there may be other numbers.

This is a specific request format X..Y, which includes all the numbers in the range from X to Y. The version that the range of numbers is too large and therefore the system does not cope with the request can be discarded.

A small investigation showed that blocking such requests by Google, apparently, is due to the fight against carders. In May 2011, Mikko Hypponen, security specialist from F-Secure, noticed that Google Mobile Search allows you to search for credit card numbers by specifying the appropriate range of numbers. Ten hours later, such requests were blocked .

Apparently, the usual Google search blocks any search queries with a large range of numbers, if such queries are repeated from the same IP address. In general, the search for "secret" information in search engines is a long-time entertainment for hackers, and only in recent years search engines have begun to somehow deal with this, blocking some specific requests.

Interestingly, in the mobile version of Google such requests with a range of numbers still return the result: www.google.com/xhtml?q=9999999..9999999999999999999999999
