2019-10-11 Slow(ish) syn floods probably targetting Maltese Casino websites 1 month ago
While looking at some network issues at home I noticed some weird traffic coming in from the outside: forged SYN traffic. Fast enough to trigger my iptables rules to stop being part of tcp syn attacks so all traffic gets dropped. Searching for a bit finds Hell of a Handshake: Abusing TCP forReflective Amplification DDoS Attacks - usenix which discusses this kind of attack. At the moment it's about 1 or 2 packets per second. The traffic itself isn't notable on my connection and even without the firewall rules it still wouldn't impact my system. But do this with a lot of systems on the Internet running some tcp service and quite some traffic will go to the targeted IP address. I guess someone doesn't like some Maltese Casino website. I don't like casino websites either because they promote addictive behaviour but I'm not about to use a DDoS.
