I took issue with this paragraph of the article, on account of several pieces of misinformation, presumably courtesy of Claude hallucinations:

> Here’s the test. If /tmp/.XIN-unix/javae exists on my host, I’m fucked. If it doesn’t exist, then what I’m seeing is just Docker’s default behavior of showing container processes in the host’s ps output, but they’re actually isolated.

1. Files of running programs can be deleted while the program is running. If the program were trying to hide itself, it would have deleted /tmp/.XIN-unix/javae after it started. The nonexistence of the file is not a reliable source of information for confirming that the container was not escaped.

2. ps shows program-controlled command lines. Any program can change what gets displayed here, including the program name and arguments. If the program were trying to hide itself, it would change this to display `login -fp ubuntu` instead. This is not a reliable source of information for diagnosing problems.

It is good to verify the systemd units and crontab, and since this malware is so obvious, it probably isn't doing these two hiding methods, but information-stealing malware might not be detected by these methods alone.

Later, the article says "Write your own Dockerfiles" and gives one piece of useless advice (using USER root does not affect your container's security posture) and two pieces of good advice that don't have anything to do with writing your own Dockerfiles. "Write your own Dockerfiles" is not useful security advice.
