A tool like this has been in the wild for several weeks.  As skeeto says
"Further, this attack has been known for years, and in 2019 it's been
used against real keys on keyservers. This tool is nothing new and does
not create any new capabilities. It's merely proof that such attacks are
very easy to pull off. It doesn't take a nation-state actor to break the
PGP ecosystem, just one person and couple evenings studying RFC 4880.
This system is not robust."

One wonders why an attack that's been known for years is only being
addressed now that it has been used.
