I have a jailbroken iPhone, and I noticed that it contains a file called social_engineering,ios,url_expression at the path:


The file is roughly 11MB in size.

Does anyone know what the purpose of this file is?

Thank you, James Pedersen

I don't use Apple products but it's probably this:

"This database, provided by Google, is used by mobile Safari to check for known malicious web sites. To check if this is activated on your iOS device, go to Settings > Safari, then look for the Fraud Warning slider."
