cellphones

When the mobile phone or data device is turned on, it registers with the mobile telephone exchange, or switch, with its unique identifiers, and can then be alerted by the mobile switch when there is an incoming telephone call. The handset constantly listens for the strongest signal being received from the surrounding base stations, and is able to switch seamlessly between sites. As the user moves around the network, the "handoffs" are performed to allow the device to switch sites without interrupting the call. Cell sites have relatively low-power (often only one or two watts) radio transmitters which broadcast their presence and relay communications between the mobile handsets and the switch. The switch in turn connects the call to another subscriber of the same wireless service provider or to the public telephone network, which includes the networks of other wireless carriers. Many of these sites are camouflaged to blend with existing environments, particularly in scenic areas.

Prosty gadget!

From the "Our Street Walkers Need to be Better Equipped" department come the platform shoes for prostitutes. Designed by the Aphrodite Project, these are the latest in greatest in hooker safety. The shoes have an audible alarm system, which emits a piercing noise to scare off attackers. The shoes are also outfitted with a built in GPS receiver and an emergency button that relays both the prostitute's location and a silent alarm signal to public emergency services. Where there are problematic relations with law enforcement.... the shoes will relay the signal to sex workers' rights groups. I don't even know what to say about this except that I'm getting them for all my girls. I'm tired of always trying to track them down to demand my money. Now I'll just use the GPS and threaten to run them over with the car.

Hackers alert

“We are in a lot of trouble,” said IOActive security specialist Dan Kaminsky, who stumbled upon the Domain Name System (DNS) vulnerability about six months ago and reached out to industry giants to collaborate on a solution. “This attack is very good. This attack is being weaponised out in the field. Everyone needs to patch, please,” Kaminsky said. “This is a big deal.” DNS is used by every computer that links to the Internet and works similar to a telephone system routing calls to proper numbers, in this case the online numerical addresses of websites. The vulnerability allows “cache poisoning” attacks that tinker with data stored in computer memory caches that relay Internet traffic to its destination. Attackers could use the vulnerability to route Internet users wherever the hackers wanted, no matter what website address is typed into a web browser.
