Switching ports, nevertheless, causes a lose in players, who don't stay tuned on the forum and suddenly their favorite server appears to be offline.

The lose will be greater than living with the attack.


EDIT: I wanted to say that turning the cookies off is useless. (conncookies 0)
From personal experience, after attempting to turn off the cookies, that "requests connection cookie." turned into "Incoming Connection", or in other words, the attacker switched to ServerFullAttack (Players couldn't connect to the server because it said it was full, and only on luck they connected)

Kalcor cannot manage the security of your virtual server where you have stayed your server sa-mp.

Sorry if i don't understand, my native language is spanish
This is ofc not the fault of Server Owners, my Server is DDoS Protected with Anti DDoS Pro from OvH, this kind of Attack is just for SA:MP Servers, there should be a away to limit the Querys per IP as a Server Config Var or atleast a new Callback "OnQueryInfo" or something like and then block the IP with exec Plugin with iptables.

Why does other Multiplayers dont have such a Problem?

Actually, No one could find a working and accurate solutions yet and many servers are being locked...

Do these requests also trigger OnIncommingConnection? If so you might be able to filter some of them by their port numbers. Genuine clients will almost universally use a random dynamic port in the range 49152 through 65535. If the port number is lower than 49152 you can temporarily block the IP using BlockIpAddress.
The issue is that the flood doesn't reach a connection, it only requests a cookies and drops off.
There are no "Incoming Connection" as evidence to this.

It could help tho if there was something in the config to do
mincookietime to limit the cookie, which is requested before the connection.


About firewalling a range, from my last two logs (2G of this shit), this won't help.
You'll need to firewall 0 to 255

I have in my logs these ip's

(from the time I turned off the cookies)

As you can see, there are 223.* and there is even one 4.* and lots of between.

What we could only do is update Gamer_Z's Anti Server Full Attack plugin, turn off the cookies and use the plugin instead.
(As of now, it seems a lot more realistic than waiting for an update from Kalcor)
But unfortunately, the plugin works only for 0.3z R4.



EDIT: I noticed that the ports are even smaller than 49152, so targeting port is also useless.

There's multiple attack types going on at the same time it seems, query flood is something servers have dealt with for 10 years now. You have to wait it out and inform your players that they can still join your server even though they can't query it.

The attacker sends the cookie request packet also not just query flood !!
Soon it is often not possible for the player to connect to the server!

My mitigation tactic is to block the first package of every query and cookie request from all the clients after the second package I release the connection!


Or to receive the querys [i, r, c] the client must make 2 requisitions of the same!

Query C hex string: 53414d50a772c94a611e63
Query I hex string: 53414d50a772c94a611e69
Query R hex string: 53414d50a772c94a611e72
Cookie connect Packet hex string: 081e77da


Iptables Rules: https://github.com/Edresson/SAMP-Firewall/

Unfortunately it does not work if it is on the same vps / dedicated node! Because the packets will cause slow connection on the VPS / dedicated!

If you have any tips to improve I would be grateful!

If I can not post this here, please let me know!

It's not like that. Read about a2s_info attack or similar. The "cookie" attack is currently not affecting server at all when logging is disabled. If you have any problems with CONNECTING (not query), then it's probably your iptables fault or just kernel conntrack table full. The main problem is with query packets.. Responding to these packets is limited internally to not perform self-ddos. The attackers are just hitting the limit and that's why legit players are unable to query server. There should be possibility to change the limit or just disable it for "i" packets.

Pseudocode for those saying there's no internal limit:

Code:
if ( dword_515D28 != a1 )
  {
    if ( sub_48DBD0((int)dword_4F5FB8) - dword_515D24 < 25 )
      return 1;

So basically the only proper solution for this query flood is a server patch, which enables to adjust the query limit, right?

Don't tell them that, we've only just stemmed the flow of cries for an update without throwing this to them to have an aneurysm about...

This can only be stopped with a firewall (despite a client update) as blocking all IP addresses with BlockIpAddress stops incoming connections but still affects the server. The amount of data being constantly sent itself is the issue.

I can see servers with port different than 7777 are working fine on hosted tab, How is that logical?

I just saw a post where people block an entire /8, please don't. This is blocking roughly 16777216 IPv4 addresses, a /24 would be more than enough, which would just block 255 IPs.

I have moved the server to many other PORTS in my root server, this doesnt matter, because the ip its targeted.
I am busy the last days with fail2ban + Suricata, and believe me ppl, im working hard to find a way out, i dont go sleep or eat anymore.

So my appeal to the ppl beyond of this...stop it in name of any what is important for you, please!

I am really sad because someone just comes and takes me and my friends our fun! For no reason? I suggest the attackers please attack the whole 400 servers MASTERLIST not only the Hosted Tabed servers, maybe everyone here in Team move their ass in our direction and help us out of this! So sad...so sad...really sad...im really really sad...really!!!
