I haven't been able to solve the puzzle - if there's any, however there is some interesting pattern in filenames.

/staticfiles/svg/error.33ab1eb5.svg -> 33ab1eb5 hexadecimal is 866852533, which seems to be a prime number.

I believe the probability is very low if unintended. Also other file names, can be factored more or less to 1 big prime number and few small primes.

These hex strings are beginnings of md5 checksums of these files:

   sh-4.3$ md5sum error.33ab1eb5.svg 
   33ab1eb5129ee5085793166d2f691dae  error.33ab1eb5.svg

I believe the point of appending them to the name is a kind of versioning: one'd want to be able to change these files and cause everyone to drop their cached version. This way when one changes a file, the filename changes too (most likely), so the cached old version will not be used.

Thanks for the explanation!

You're correct.

It looks like they're using Django. You can configure it to add the md5 of static files to each name. [1]

Have you ever seen the movie PI? You sound like Max, the main character.

The pattern is they're all hex, we need a cryptographer. The three numbers are
