Ask HN: Dangers of Unsecured WiFi?

#1
Connected to an unsecured WIFi network last week from my MacBook. When I restarted I couldn’t login and had to go through safe/recovery mode and use reset password utility from the terminal to get back in (thankfully I could log in to my Apple ID.

Now I’m not able to login to my Firebase console even from another laptop.

What’s going on here?

Have you confirmed you are locked out of Firebase? Performed a password reset?

If you get to login, check your compute resources since most of these bots just deploy tons of compute and use them for DDOS. This can be in the hundreds of dollars per hour figure.

It is possible to have your session hijacked when using any wifi really, its a lot harder on secured wifi though.

I only tether to my phone now in public, and never use unsecured wifi for anything.

Didn’t try the password reset until you mentioned. Thanks, that worked.

Google did send me two Security alerts (one for each laptop) when I tried signing in yesterday with my old pwd. So they must have reset my password or something?

In any case, lesson learned: never connect to an unsecured Wi-Fi again! (I rarely do, but I was at this conference last week trying to demo Appomate AI, and was wanting it to be as snappy as possible. Bad decision!)

unless you accepted an invalid https certified popup, its not possible, even on public wifi. or maybe you still type: http:// instead of https:// , and then is easy to fake a dns response to point to a clone site

Ironically because MITM attacks for corporate security are that common, a lot of developer tools are configured to just ignore TLS checks instead of importing the correct root certificate.

In case of an unsecured WiFi connection this is of course much more dangerous even.

I once connected to unsecured wifi and 2 minutes later started getting ungodly amounts of spam, just spam everywhere filling up my inbox etc.

I started panicking, going over to people around me asking if they've ever experienced such a thing. All I got was a bunch of "huh? no never"s.

I found out a couple hours later that by pure coincidence my friend pranked me right then by signing my email address up for all the spam newsletters etc. he could find....

Hehe….life would be so boring without coincidences!

But I definitely panicked too and still a worried if I carried something over to my home network.

I’m a developer and at least superficially aware of the issues. Can’t imagine what non techies go through when faced with such situations!!
