Fetch-url-file-3a-2f-2f-2fproc-2f1-2fenviron

The string appears to be URL-encoded (percent-encoding), with -3A representing : and -2F representing /.

Decoding process:

| Encoded | Decoded | |---------|---------| | file-3A | file: | | -2F | / | | -2F | / | | -2F | / | | proc | proc | | -2F | / | | 1 | 1 | | -2F | / | | environ | environ | fetch-url-file-3A-2F-2F-2Fproc-2F1-2Fenviron

Decoded result:
file:///proc/1/environ

file:///proc/1/environ points to the Linux procfs file containing the environment variables of process ID 1 (typically init or systemd). The prefix fetch-url-file:// suggests that the software is

The prefix fetch-url-file:// suggests that the software is treating the local filesystem path as a URL resource. This abstraction layer allows the tool to handle local files and remote URLs using the same logic. While functional, it can sometimes introduce confusion regarding permissions and path resolution.

If you are seeing this in a tool like Ghidra, it means the tool is trying to load the environment variables of the first process running on the system. This is often done in: fetch-url-file-3A-2F-2F-2Fproc-2F1-2Fenviron

sudo cat /proc/1/environ | tr '\0' '\n'

with open("/proc/1/environ", "rb") as f:
    data = f.read()
    env_vars = data.split(b'\x00')
    for var in env_vars:
        if var:
            print(var.decode())
