O2 Giving out phone numbers?

If this was really an issue wouldn't we all be getting flooded with cold sales callers, because personally I'm not and I'm on o2

Not if no one knew about it. Now the cats out the bag it can be used.

Can't say I'm particular happy about it. Once loopholes are found they can be exploited. Imagine if a few advertising banners started searching the header.
 
Exactly. This is the first I've heard of it.

*Runs off to modify all his websites to grab x-up-calling-line-id and store it in a database.... Muwahahaha*

depends:

it could be a new thing.

its possible that it just hasn't been spotted before, if it isn't documented then nobody bothered to look I suppose. It was only seen in this case by random chance.

edit: beaten like a ginger step-child
 
The potential for spam abuse is lower on the cell network than land-line but that potential is only likely to increase sooner I fear than later.

Personally I'm rather unamused that this detail is transmitted in the headers.
 
Google suggests its been known since 2006
Back in 2006 - or even 2010 - no one cared about what mobile browsers did. Now though mobile internet browsing is becoming ever more prevalent - to the point where sites are being specifically designed with mobile in mind.

Any security holes or privacy breeches, however seemingly minor, will be big issues the more people become susceptible to them.

My point is, people that want this sort of data aren't stupid and if this http header has been in use as far back as 2006 they'd be mining the data already.

As for the fact that if it's not being used as no one knows about it this thread is kinda ironic.. :D

I agree, looking in google it certainly does appear to be documented quite a bit so its surprising it hasn't be raised much as issue publicly, however, if you did get a spam call and you didn't know about this issue you would just think it was random when in fact it was targeted.

Also, im not trying to witch hunt O2 it just felt like something that people would want to be aware of, thats all.
 
Ignoring (un)reality for a moment. But if your home adsl connected PC was churning out your land-line number to every site you visited ... well the repercussions do not even bear thinking about!
