If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

A custom setuptools install command writes a shell script into a temp directory that sleeps ~300 seconds, downloads an ELF binary from https://file.freestorage-04.bond/files/.../boto3_utils.elf via curl/wget, chmod +x's it, executes it detached via nohup as /tmp/systemd-helper, and then self-deletes the launcher script.
