Some do inspect the script, but then still run it using curl | bash anyway.
Incidentally, this very relevant blogpost about detecting curl | bash and serving different scripts based on that is almost exactly a decade old:

Copy Fail: Linux Kernel Flaw Grants Root Access On All Major Distributions
A Linux kernel vulnerability called “Copy Fail” (CVE-2026-31431) allows unprivileged local users to gain root privileges with 100% reliability by corrupting the shared page cache. The flaw affects nearly all Linux distributions since 2017 and enables container escapes because the memory corruption does not modify files on disk.
If you run Linux servers, especially shared environments like Kubernetes clusters, CI/CD runners, or multi-tenant hosts, patch your kernel immediately to a version that includes the fix (mainline commit a664bf3d603d) for CVE-2026-31431. If you can’t patch right away, disable the vulnerable module by running echo “install algif_aead /bin/false” > /etc/modprobe.d/disable-algif.conf followed by rmmod algif_aead, and for untrusted code environments block AF_ALG socket creation via seccomp as a long-term safeguard. #cybersecurity #infosec #advisory #vulnerability https://beyondmachines.net/event_details/copy-fail-linux-kernel-flaw-grants-root-access-on-all-major-distributions-w-l-v-0-c/gD2P6Ple2L

Haven’t had much new stuff to report on this topic for a bit…until today!
3 new arrivals to the deleteduser dumpster:
-
a company that handles public/guest wifi access in Europe
-
An EU based sports club booking platform
and, extremely concerningly:
- a period tracking app, that emails out full PII and data
All have been contacted.
In lighter plexfiltration news, a developer who was testing something out sent a ‘hello, test’ message to a ‘deleted user’, so I was able to respond with ‘test worked - hows it going?’ which I can only assume really freaked them out.
Out of the now 60ish orgs contacted, have heard back from 2 who have fixed their use of deleteduser.com. I’d say that maybe 3 or 4 have dropped off, but the rest still continue.
Ironically, this includes all of the tech and cybersecurity companies that were contacted.

CIO by day, cybersecurity professor & Forbes Contributor by night, and a firm believer that the best ideas start with good coffee. I’m passionate about using AI, cloud tech, and leveraging system dynamics to make work (and life) a little easier. Outside of work, I’m either reading/writing in some indie coffee house, hiking shady trails along the river, or adding to my ever-growing collection of houseplants. I’m always learning, always leading, and always up for a good book or a new coffee house to explore. #CyberSecurity #systemstheory #hiking #philosophy #actor #improviser #storyteller #coffee house addict 📍Chicago, IL 🦋🥾☕️🎭🤖🪴✍️
