A pseudonymous coder has created and released an open source “tar pit” to indefinitely trap AI training web crawlers in an infinitely, randomly-generating series of pages to waste their time and computing power. The program, called Nepenthes after the genus of carnivorous pitcher plants which trap and consume their prey, can be deployed by webpage owners to protect their own content from being scraped or can be deployed “offensively” as a honeypot trap to waste AI companies’ resources.
“It’s less like flypaper and more an infinite maze holding a minotaur, except the crawler is the minotaur that cannot get out. The typical web crawler doesn’t appear to have a lot of logic. It downloads a URL, and if it sees links to other URLs, it downloads those too. Nepenthes generates random links that always point back to itself - the crawler downloads those new links. Nepenthes happily just returns more and more lists of links pointing back to itself,” Aaron B, the creator of Nepenthes, told 404 Media.
More accurately, it traps any web crawler, including regular search engines and benign projects like the Internet Archive. This should not be used without an allowlist for known trusted crawlers at least.
Just put the trap in a space roped off by robots.txt - any crawler that ventures there deserves being roasted.
Yup, put all the bad stuff into “not-robots.txt”. Works every time.
More accurately, it does not trap any competent crawlers, which have per domain limits on how many pages they crawl.
You would still want to tell the crawlers that obey robots.txt do not pay attention to that part of the website. Otherwise it’s just going to break your SEO
How exactly would that work? Would trusted crawlers be blocked from accessing the maze?
You can tell what crawler its is by useragent header
Which can easily be faked.
But then they’re probably not going to obey robots.txt anyway so it doesn’t matter
Most legal robots do. Those who don’t - among them many AI feeders - deserve to be drowned in the shit that the honeypot delivers.
All of cyber security is an arms race of moving targets. It doesn’t need to be foolproof to mitigate traffic for a while.
Yeah and then you allowlist them by blacklisting them from the maze.
