Thanks for the nice words... This (having a rogue top CA ruining the entire SSL system) is a known vulnerability in the SSL architecture and it has already been used to infiltrate MS Windows updates. For this reason if you want real security you dont' use the current SSL CA structure. People don't talk too much about it for various reasons, banks don't want to create panic, government wants easy wiretap, etc. If you are happy with current top CA lists that comes with the standard browsers you really are giving your security keys to people you don't know and that are not "certified" at all. Good luck!

Submission + - Bitcoin: earn money on emerging market BTC rate spread (mercadobitcoin.com.br)

fabrica64 writes: If you are an EU national residing in Brazil you can, theoretically, earn on Brazilian inflated BTC rates at biggest local exchange (www.mercadobitcoin.com.br)
Local BTC exchange is trading BTC with a 13% premium over BTC-EUR rate, so, for example, if I have 1 bitcoin I can trade it for 1473 Reals (BRL) and then trade 1473 Reals for 489 Euro (at 3.011 rate) and buy 1.132 BTC at current rates on BTC-e (July 30, 2014, 19:19 UTC) with a 13+% gain
Transferring Reals to Euro, if you are a legal resident in Brazil, will cost you no more than 4%, and even paying another 4% for additional fees you end up with 5% gain...
I guess the same is valid for USD.
Has anyone ever tried that?

The system works this way:
- there is a blacklist of TAC (initial part of IMEI that identify manufacturer, model and sub model: http://en.wikipedia.org/wiki/T... [wikipedia.org])
- actually info for this blacklist is furnished by manufacturers, that will probably include all their models regardless of being or not sold in Brazil, but this can be later changed by Anatel, restricting the list
- there will be a whitelist of "blacklisted IMEIs" activated in the network before March 17th, 2014
- there will be a blacklist of permitted IMEI (e.g. an iPhone sold in Brazil) that were used (i.e. cloned) in "IMEI configurable" Chinese smartphones/tablet
- there will be a whitelist of IMEI+IMSI to identify the original cloned (I don't know who will identify the original one if many claims to be the original one)
- block will be set in the network on each individual IMEI
- permission will be set in the network for specific IMEI+IMSI
- the system is tailored to control individual IMEIs and not only generic TAC
Do you see the potential of chaos? Chinese smartphone seller will setup "change your IMEI daily" services and it will be cat and mouse play until a complete mess... and mobile operator will hardly divert resource to help in solving it or handle complaints...
