You're getting downvoted, but the guidelines explicitly say:
> Please don't insinuate that someone hasn't read an article. "Did you even read the article? It mentions that" can be shortened to "The article mentions that."
Yeah and guess how good it works offline. You don't even know which country a place is in if you only know coordinates and have no access to the smartphone. Do a typo and there's no redundancy or error correction. You'll end up in some ocean then.
These attacks are valuable inputs for new generations, but no cause to consider 3G and 4G insecure in practice.
The authors learn about user's activity and location. But the comments often lack understanding what that means in context of mobile networks. Usually, it simply means:
* Is the user currently active in the cell?
If yes, the user's location is known (somewhere in this cell) and also his activity (he's online, otherwise he wouldn't be present). The authors here present an issue where the authentication procedure allows tracking with some probability.
> or when you wanna ride more relaxed, you ride on the sidewalk.
Common misconception. Riding on the sidewalk is considerably more dangerous than riding in the street. While you are less likely to be hit from behind, you are much more likely to be hit by drivers turning.
> If you were in a car, you would be the type of person that honks at cyclist because in their mindset, it's illegal.
The difference is that blocking the bike lane is typically illegal (and dangerous to cyclists), and riding a bike on the road is typically legal (and at most irritating to drivers). The two are not equivalent.
Riding a bicycle on the sidewalk is illegal in almost every state and country. Riding a bicycle in the street is never illegal. I think you should learn the rules before you tell people that they should risk their lives for your convenience.
Riding a bicycle is illegal on some roads, especially the highway (unless it's the only reasonable road, such as though a canyon).
That being said, far too many assume it's illegal to ride on the road, and "share the road" signs don't seem to effectively correct that misconception. I've even heard of drivers telling cyclists to ride on the sidewalk when they're already riding in a bike lane...
That being said, and as others have stated, riding on the sidewalk is not illegal in many areas, though it's less safe in most.
The Internet was English speaking, western and had a keyboard with the Latin alphabet. These days are over, but it's injust to argue with ideology and a negative tone here.
The Internet serves people all-over the world and must respect local laws, because it serves the local people.
Also, free expression is stronger than ever before. You can now even claim your opinion is a fact.
To me, it's absolutely unclear what the author is actually talking about. Should telcos be responsible for monitoring the devices in their network?
Mobile networks provide Internet access with all the risks associated to the Internet. But the radio access is reasonably secure, if we compare with public WiFi. It's encrypted, authenticated and the operators are more trustworthy than the random person that puts up an Access-Point with years-old firmware. (the operators have something to loose here)
"use VPN" is a pretty strange advice if you consider how any shady providers there are. Switching you phone to 4G-only pretty much gives the same level of trust in the radio access.
Covering the webcam is just ridiculous. If someone has access to the webcam without obeying the standard interfaces in your browser and asking for permission, then the problem is not the webcam picture. Your computer is controlled by someone else.
Also I have trouble recommencing 2FA. User, password and e-mail access is considered one factor. Adding another one increases security over that - even if it's insecure SMS. But it often completely disables fallback authentication. The advice for 2FA should be: if you need 2FA, add a minimum of tree factors to allow recovery.
> Do international tensions actually reach down to students, if they obey the law and manner of respect?
Yes, international tensions are often about things that aren't illegal, and even where they concern things which one state views as illegal, they often target people suspected who may not always be guilty. And even if they target only the actually guilty, when it relates to communication systems, that can have impacts on people several hops removed from an actual target.
