Found some GitHub issues  with something similar: an enterprise firewall blocking a repo because it contained the string "arglebargleglopglyf"  in some tests.
The text was flagged as malicious because of its presence in the repo github.com/wireghoul/htshells . However, the whole point of the word in the htshells repo is that it's an invalid command that breaks Apache, so it could have been almost any random string.
