Are QR codes threats?

Hi All

Here is an interesting topic, everyone uses QR codes - can they be malicious?

Aye, matey, there be QR codes that can tear the VPN out of your firewall like a shark going after a bucket o' guts!

I've taken to posting my details in a QR code on the first slide of my presentations, as:

Oddly, when people find out I am a malware researcher, nobody actually scans the code ...

@rsladethey could be a little cautious - especially I wonder that COVID-19 code will take me when I register at a shop?  Does your QR code take people's devices to /dev/null or to the Dark Web to an obscure place?

How can we verify a QR safely without compromise?

Are there tools available in portable mode, so one does not compromise oneself?

The biggest issue I have seen with QR codes and for that matter link shorteners like bit.ly is that today they could go to a legitimate site and tomorrow they could point you to malware.

Be very careful....

I read recently that you can add a + sign to the end of a bit.ly link, and it will preview the link safely.

https://bit.ly/1sNZMwL+, for example (and it should point to the Bitly Wikipedia article)

Can't say the same for QR codes, however...
