Denial Of Service Attack Update

Dear All,

We were hit with a denial of service (DOS) attack today beginning around June 12th 2019 @ 01:27:51 PM from an IP address registered to "RACKWEB-NET" in Bulgaria.

I was notified about this around June 12th 2019 @ 03:05 PM and did some log file analysis and discovered how the attack was happening and wrote some code to mitigate against the attack.

I think the site was down for about 1 hour and 19 minutes because of the attack.

The code I wrote will filter against these kinds of DOS attacks in the future.

Thank you for your support,

Neo

EDIT: In addition to the PHP changes, I made some changes to the DB configuration as well to help insure this kind of attack cannot succeed in the future.

NAME
crack-attack - multiplayer OpenGL puzzle game like "Tetris Attack" SYNOPSIS
crack-attack {{[--server PORT] | [-X] | [--wait]} {[SERVER] | [-X]} {[--solo] | [-X]}} [--name NAME] DESCRIPTION
Crack Attack is roughly based on the Super Nintendo game "Tetris Attack". Slowly, your stack of colored blocks grows from the bottom, and you've got to make sure it never reaches the top. If it does, you lose. To eliminate blocks from the stack, line up at least three of one color, horizontally or vertically. Once you do, those blocks disappear, and put off slightly your inevitable demise. Crack Attack essentially requires hardware acceleration. For Xorg users, this means you want DRI. COPYRIGHT

It is important to realize that the name of Crack Attack! X-treme play mode is meant to be humorous, and thus should not itself be the subject of derision. Thank you. AUTHOR
