Ask HN: Is it even possible to crack a Wi-Fi password from a phone?
I've heard some people bragging about this and saying they use free internet, but I think it's impossible because there's no internet on the phone, even through Termux: aircrack-ng, hashcat etc.
I mean, I don't know how they do it, maybe they're lying, but if it's possible, then we can safely say that Wi-Fi security is critically low right now.
- pamcake 9mo agoCracking the key? A WPA3 network with a strong unique key should be safe. Sometimes defaults are predictable and users don't change. Sometimes "getting free internet" doesn't involve cracking WPA keys. Think unencrypted hotspots with bypassable captive portals and devices with ancient firmware and exploitable CVEs. I think what we can safely say is that negligent wifi access point operators exist in most residential areas.
- JohnFen 9mo agoIt is possible for an attacker to crack WPA3 in such a way that they can connect to the network. It's not fast or easy, but it can be done. It's not impossible that it could be done with a smartphone, although that would make the task even more difficult. Since you can't really "casually" crack WPA3 (as far as I'm aware), I doubt that anybody is doing it that way. They'd be more likely to pick up more suitable kit for $100-$200.
