I knew it was a scam E-mail, I already got some similar ones with old passwords I don't use anymore.
But the sentence "if you want to find out more - Google: "Drive-by exploit" stimulated my curiosity.
So I did the google search exactly as suggested, or maybe "what is a Drive-by exploit".
I like to learn this kind of stuff. I was on my android phone in the bus, too relaxed.
So I opened quite randomly the first 2-3 google links without thinking too much.
Also this one (I think, 99% sure, I didn't make any screenshot):
!! I make the link unclickable !! https: slashslash howtoremove.guide slash remove-drive-by-exploit-email
Even if I know I have (had?) no malware.
Well, the Chrome page opened but showed suddenly something like "loss of network connection".
I looked at the android status bar. The 4G symbol disappeared for some seconds. Then came back.
This in a place where there is always 100% high signal.
Question: may I have got a malware like that?
Or this ON/OFF/ON is just a coincidence?
It would be ironic and a bit sci-fi if I get a malware by a drive-by download after connecting to a web page the guy spamming me hopes I open following his suggestions.
However, I turned then my mobile phone off, removed the sim card and I spent some time to factory reset / reinstall all the usual stuff.
And then i put the same simcard back, I can not be too paranoid.
I am still waiting all the day for the results of hybrid-analysis on the web page.
Tons of submissions pending, I don't understand it.
However virustotal and the android static analysis results are not all green. https://www.hybrid-analysis.com/sample/69b61e0b4b800586e84bc373eb3b181f092ae694d0c3dcdf39b88c422fcffc7d
