#DDoS Attacks on the Rise, but How Can You Prevent One?

DDoS attacks are increasing each year. But what actually are they? And how can your business prevent them from occurring?

I'm having trouble figuring out what kind of botnet has been hammering our web servers over the past week. Requests come in from tens of thousands of addresses, just once or twice each (and not getting blocked by fail2ban), with different browser strings (Chrome versions ranging from 24.0.1292.0 - 108.0.5163.147) and ridiculous cobbled-together paths like /about-us/1-2-3-to-the-zoo/the-tiny-seed/10-little-rubber-ducks/1-2-3-to-the-zoo/the-tiny-seed/the-nonsense-show/slowly-slowly-slowly-said-the-sloth/the-boastful-fisherman/the-boastful-fisherman/brown-bear-brown-bear-what-do-you-see/the-boastful-fisherman/brown-bear-brown-bear-what-do-you-see/brown-bear-brown-bear-what-do-you-see/pancakes-pancakes/pancakes-pancakes/the-tiny-seed/pancakes-pancakes/pancakes-pancakes/slowly-slowly-slowly-said-the-sloth/the-tiny-seed

(I just put together a bunch of Eric Carle titles as an example. The actual paths are pasted together from valid paths on our server but in invalid order, with as many as 32 subdirectories.)

Has anyone else been seeing this and do you have an idea what's behind it?

Sales pitch toward the end.

Nachdem diverse #ki #ai #crawler besonders respektvoll mit den öffentlichen Ressourcen von Open Source Projekten umgehen, habe ich mich dazu entschlossen eben diese auszusperren. Wir hatten in der Vergangenheit crawls, die im #monitoring als #ddos gewertet wurden.

Diverse AS erfreuen sich nun einem dauerhaften 429, einige wenige die es für alle kaputt machen…

The Dutch web hosting company Argeweb has experienced performance issues for over a week now.

I'm getting #DDOS-ed by #AIcrawlers right now, even though I have a strict robots.txt.

Outgoing traffic suddenly increased (more or less 10 times regular traffic).

I have to block their crap using my firewall. That's NOT OK.

An interesting code hosting related downside of AI. #ai #ddos #web #scraping #copyright #code

Who could have guessed that an industry whose entire business model is based on theft would behave like malware attacks on the Internet?

DrayTek routers in the UK (and to a lesser extent elsewhere) are having A Bad Weekend. Lots of "spontaneous" reboots.

Also, DrayTek's UK website is unreachable. So this looks like a concerted attack.

Details are patchy, but ISP Review is tracking the problem: https://www.ispreview.co.uk/index.php/2025/03/broadband-isps-report-uk-connectivity-problems-with-vulnerable-draytek-routers.html

Applying firmware upgrades and disabling VPN services will help. Search your networks for indicators of compromise.

Artificial intelligence companies are creating incredibly large scale denial of service situations on the infrastructure of Open Source Networks.

Now Network owners need to waste time on Finding ways of sending All These requests of the rogue AI insects to /dev/null
