That's a huge step Yen,. it requires an open phone. People who leave their phones open and unattended in strange places need their head examined in the first place.
Someone managed to physically get a hold of, and use 7/9 peoples phones, which were left unlocked and unattended, in a public cafe/restaurant ? Source? If you physically get a hold of someones device, be it mobile, PC, laptop, or anything, and they are not locked, you can do pretty much what you like, nothing special about whatsapp
This issue has nothing to do with the device and more with the stupidity of the people using the device. So how does using another phone help the issue ?
I think he was joking -- Back on topic: If you leave your car unlocked with the keys in the ignition, near someone looking to steal a car, guess what is likely to happen! Nothing wrong with the security of the car itself, just the fact it wasn't used, and was left open to bad guys
or good social engineering.. "Hi how you doing. i work for (insert cell phone co here) and im doing a survey of users with whatsapp for a chance to win a new phone' all i need to do is add you to my contacts list and we will contact you if youre a chosen winner"
Yes that would get a lot of people, but they would probably just offer their phone number. How many would let you scan ?
As soon as someone asked to scan my phone, or take my number for a chance to "win" something, I'd tell them to jump Same as when even my own carrier cold calls me with the promise to save me money, GTFO, companies don't call people to lose money, or stop them paying that company as much, it's always in the companies favour, no matter what they tell you, somewhere down the line it will cost you more
part of it is to "take a pic of your phone maam.. to show who has the most need for it during winner selection"
web.whatsapp.com will only allow qr scanning if it detects user agent as non mobile (including tablet)
I don't speak German or whatever that video is in, so.... lol Have no sympathy for people leaving their unlocked phones unattended in a public place, might as well just give some stranger all your details instead Would never hand over my phone to anyone, no matter how beautiful, if they needed help, I'd call for them
Well, you know it best how many times you've borrowed your phone somebody already or if at all...or how many times you've left it unattended somewhere... It all depends on the will to have access ...and if it's just for 'proof of concept'...to impress friends One simply could 'steal' the phone and bring it back later...watching friends how many times they mislay their phones..quite easy.... Either way a simple verification implemented and the design flaw would be gone...
Nobody gets my phone, I never leave it laying around if anyone else is here, and if I am out it stays in my pocket And it is locked This whole thing is the same as saying if you leave your front door unlocked, and money on the table, someone could come in and steal it Well, yea, lock your door, and don't leave money lying around for people to steal -- If I leave my computer running, someone could read my emails, they could set up forwarding to another address, they could install a keylogger, enable remote access In all cases, the attacker has to have physical access, if they have physical access, that's your own fault
That's the issue and why I don't think this is a design flaw. The verification is access to your phone. If I decided to not put authentication on my phone then you can access What's App and do whatever you want. But you can also access the entire SD card, the phone book, all my messages on sms, emails, everything. So why not say it's a design flaw of those apps ? It's like saying if I don't put a lock on my front door and I have a drawer with no lock with money in it and someone steals it. What do I do blame the drawer and say that's a design flaw when the front door is always open ?
