Python's "multiprocessing" module, which creates the "pymp" temporary
directories for each process. This directory is automatically cleaned
when the Python process terminates. If the Python process terminates
abruptly, the directory is not cleaned.

Hi,
I'm running a production server on Ubuntu 22.04.5 LTS hosted on
digitalocean (this droplet is running since 2023). Now, recently I saw
some strange files in /tmp that were not there before. These files
contain the string pymp:
# find /tmp/ -ls |grep pymp
3762 4 drwx------ 2 root root 4096 Nov 17
22:23 /tmp/pymp-n7uodgt6
4045 0 srwxr-xr-x 1 root root 0 Nov 17
22:23 /tmp/pymp-n7uodgt6/listener-0lcaibxe
2210 4 drwx------ 2 root root 4096 Nov 17
18:18 /tmp/pymp-fciod9wd
2369 0 srwxr-xr-x 1 root root 0 Nov 17
18:18 /tmp/pymp-fciod9wd/listener-fwhwjxcb
What are these files and does in mean my server (droplet) has been
cracked?
There were more files like this which I deleted.
Thanks,
Uri Rodberg, Speedy Net.
