Those skilled at the housekeeping functions built into SS7 can locate callers anywhere in the world, listen to calls as they happen or record hundreds of encrypted calls and texts at a time for later decryption (Google translation of German original). There is also potential to defraud users and cellular carriers by using SS7 functions, the researchers say. This is another result of security being considered only after the fact, as opposed to being part of the initial design.
What makes Ripple different from Bitcoin? Strictly speaking, Ripple isn't the name of the digital currency but of the decentralized payment network and protocol created and maintained by the eponymous Ripple Labs. Users of the Ripple system are able to transact in both cryptocurrency and regular fiat currency like the dollar without passing through a central exchange. XRP is the name of the native unit of exchange used in the Ripple network to facilitate conversion between different currency types.
Although Comcast has said its subscribers have the right to disable the secondary signal, the suit claims the company turns the service on without permission. It also places "the costs of its national Wi-Fi network onto its customers" and quotes a test conducted by Philadelphia networking technology company Speedify that concluded the secondary Internet channel will eventually push "tens of millions of dollars per month of the electricity bills needed to run their nationwide public Wi-Fi network onto consumers." The suit also says "the data and information on a Comcast customer's network is at greater risk" because the hotspot network "allows strangers to connect to the Internet through the same wireless router used by Comcast customers."
