Progenitor of the Weird Knife Wednesday feature column. Is “column” the right word? Anyway, apparently I also coined the Very Specific Object nomenclature now sporadically used in the 3D printing community. Yeah, that was me. This must be how Cory Doctorow feels all the time these days.

  • In my case the pattern appears to be some manner of DDoS botnet, probably not an AI scraper. The request origins are way too widespread and none of them resolve down to anything that’s obviously datacenters or any sort of commercial enterprise. It seems to be a horde of devices in consumer IP ranges that have probably be compromised by some malware package or another, and whoever is controlling it directed it at our site for some reason. It’s possible that some bad actor is using a similar malware/bot farm arrangement to scrape for AI training, but I’d doubt it. It doesn’t fit the pattern from that sort of thing from what I’ve seen.

    Anyway, my script’s been playing automated whack-a-mole with their addresses and steadily filtering them all out, and I geoblocked the countries where the largest numbers of offenders were. (“This is a bad practice!” I hear the hue and cry from specific strains of bearded louts on the Internet. That says maybe, but I don’t ship to Brazil or Singapore or India, so I don’t particularly care. If someone insists on connecting through a VPN from one of those regions for some reason, that’s their own lookout.)

    They seem to have more or less run out of compromised devices to throw at our server, so now I only see one such request every few minutes rather than hundreds per second. I shudder to think how long my firewall’s block list is by now.





  • They also need to be able to replenish that stock at current prices. I’ve worked retail many times in my life and arguably kinda-sorta do so now (albeit largely over the Internet) and I’ve never run any store where we did not set our pricing by replacement cost rather than original invoice cost. In my current operation there are some rare exceptions for clearance items and the like, but for the vast majority of products we sell for what it’s going to cost me to get the next one to put back on that shelf, not what it cost me for the one I’m selling you now.

    I don’t have any insider insight into other companies’ operations, but I imagine a lot of other retailers work things the same way. Especially these days.



  • I run an ecommerce site and lately they’ve latched onto one very specific product with attempts to hammer its page and any of those branching from it for no readily identifiable reason, at the rate of several hundred times every second. I found out pretty quickly, because suddenly our view stats for that page in particular rocketed into the millions.

    I had to insert a little script to IP ban these fuckers, which kicks in if I see a malformed user agent string or if you try to hit this page specifically more than 100 times. Through this I discovered that the requests are coming from hundreds of thousands of individual random IP addresses, many of which are located in Singapore, Brazil, and India, and mostly resolve down into those owned by local ISPs and cell phone carriers.

    Of course they ignore your robots.txt as well. This smells like some kind of botnet thing to me.


  • I’ve got a Timex Expedition that I’ve had since high school. That means I bought it some time during the early Triassic. Its stainless steel backplate is held on with four Phillips screws and I have never in many decades had any problems undoing them when I need to replace the battery every six years or so. It remains resolutely waterproof. I know this because it lives outside rather frequently: at the moment I have it stuck to the gauge cluster on one of my motorcycles with Velcro.
