How the FSF Sysadmins are Blocking Botnets with reaction https://m.slashdot.org/story/456168

Quote:
For nearly two years the Free Software Foundation has been fighting web crawlers (including many aggressively scraping training data for AI models). A botnet controlling about five million IPs hit one system for six months in 2025. Their systems administrator wrote this week that they view these as distributed denial-of-service attacks.

How are they fighting back?
We noticed patterns in the scrapers that were abnormal, which gave us material for writing regular expressions. Searching for the regular expression then gave us a large lists of IP addresses. Looking up the origin of those IP addresses revealed that some of the crawlers were using botnets of residential IP addresses to scrape faster and avoid detection. We looked for what kinds of botnets might be generating the kind of traffic that we were seeing, and one that we suspected was called the "Vo1d" botnet, comprised of smart TVs running some sort of compromised app... We got confirmation that at least some of the botnet traffic hitting GNU Savannah was originating through the Vo1d/Popa botnet.

We placed our regular expressions in fail2ban, and found that we were hitting the maximum rules that could be added to UFW firewall rules on our systems which showed degradation around 65,000 rules... We learned about ipset and configured fail2ban to add IP addresses that it found to IP sets. Using ipset, we kept building larger IP sets and did not find instability with as large as five million rules...

We eventually found a promising project on Framasoft's forge Framagit called reaction written by ppom... After we ran into scaling issues with our initial implementation, we developed a much faster implementation where the reaction shutdown process would export the IP sets to disk and the reaction startup process would restore the IP sets. This allowed us to have nearly instantaneous restarts of the service to apply new rules. We published both of our configurations upstream to reaction's wiki so that everyone can benefit from it. reaction's getting started documentation now leads to the method that we proposed...

Many sysadmins know about fail2ban, but not enough people know about reaction. I am very grateful to ppom for the help they have provided and for the tremendous project they have released to the world with reaction. We have implemented other defenses as well, but reaction is doing the majority of the automated work keeping our sites online.

Hello as well Attila, I'm getting this too but not only for replying in threads, I also can't start a new topic. I also get "forbidden you do not have permission to access.."

**edit** Weirdly some users I can reply to but others I can't(opera browser), I tried using a different browser (chrome)and can reply to the ones I couldn't with the first browser but then other users that worked with the first browser now don't with the second.

I also can't start new topics with Opera but seem to be able to with Chrome. (I thought these browsers used the same base code anyway)
Tried clearing cookies and the usual stuff.

Is it possible to fix the vertical alignment of poster info and avatar picture so that they are at the upper part of the post instead of middle?

Forum interface suddenly changed from vintage nineties to rounded slick. But now I don't see a way to click back from a topic to the sub-forum it is in. The Jump to in the bottom does not work, and the top url can only go to home.

Creepy Crawlies https://people.kernel.org/monsieuricon/creepy-crawlies


Quote:
You've probably heard me complain about the “AI crawlers” before, but now I actually have some hard numbers I can put up to show their impact. In a few words, it's bad enough to create a constant “background radiation” of system load, permanently tying up a chunk of capacity spent on producing output that is only useful for a single purpose — feeding a learning model.

TL;DR: we spend more CPU cycles rendering commits for scrapers than we spend on all other kinds of legitimate access, including git clones. At any one time, across 5 geo-distributed nodes, there are 14 CPU cores doing nothing but rendering git commits as html.
