this is to share with you that I am experiencing a ddos attack for a webserver I manage.
It is a Drupal/PHP/Nginx platform that is flooded with GET requests such as:
It targets the search module which does not cache the data and means resource impact.
This involves more than 12'000 individual ip addresses, spread over CN, IN, KO, MX, and US.
A list of the subnet part involved can be found here.
(list is of course gorwing over time, attack is not over and spread of hosts continue)
I plan to further investigate the networks involved, how likely they are cloud nodes or infected hosts for instance.
I am on the AS3303/Swisscom BTW.
Is anyone experiencing such traffic?
This is not huge in terms of bw, but scaled adequately to eat servers cpu resources.
