Stumbled across this news on the internet this morning:
Was pretty shocked, but checked the affected models list. We'd just brought some HP Probook G4 450's this week at work, fortunately they were not on the list.
However checking the system, I found the driver was installed & working, and also found the log file as described.
Really poor form HP. The security implications are tremendous, and this will probably become a target for malware before long if not already. This accidental exploit has been active in some systems since 2015.
There was a lot of fuss about Lenovo having dodgy software installed from factory, although this HP issue seems to have been done by mistake, rather than done with intent.
