Google crawl errors that look like a hacker

Google has told me one of my website has a big increase in crawl errors (exactly 99). All the errors are in this format:

google crawl error /user?732e_name=ee&67ef_name=f7&1162_name=2b&c9e0_name=0c

This looks like a URL trying to hack into the user page. But it did come up in the Google Search Console – I would not have thought a hacker’s “fails” would display there.

Does anyone know what this is?
