[Tool] Check if an email address is valid – the php way

In an older post we talked about checking the validity of an email address.

Now let’s make a php function to automate this task. We can use this type of validation to check for example if a user is using a correct address when registering for a service.

Attacking the lottery

This is purely a theoretical attack on a lottery system. No magic combinations or generators, no syndicates or reading the stars, just a plain attack on the system.

First of all, there are some perquisites. One will need an insider or more in order to carry out the attack, but this should not be a problem based on the fact that a lot of attacks come from the inside. The second matter would be to get access to the central machine taking care of the database. Again, if not well protected, an insider should be able to provide enough data to gain access.
