32-bytes attack, block to all clients..

Post by Skcaj »

A few days ago my server has been suffering many attacks, and the attacker has found the weak point on the server .. it turns out that what used as attack is a vulnerability in the NFO Server, more specifically, its filters, which apparently makes otherwise to protect on this occasion, it is impossible to stop this attack activates a filter that prevents my clients to enter.

I would like to give me an alternative or can solve .. Since OVH does not work in this attack, the attack on the company turns out to be inefficient and do not tell me that blocking packages the size of 32 bytes in my case because I can not limit they are important for my server.

That's not really a vulnerability in our system. What you've described suggests that the attacker just figured out how to make a UDP spoofed-traffic attack look like legitimate traffic, such that it can't effectively be filtered.

You'd have to open a support request to have us look at the attack in more depth and see if there's anything that we can filter it on apart from the length.
