Zfone™ is a new secure VoIP phone software product which lets you make encrypted phone calls over the Internet. Its principal designer is Phil Zimmermann, the creator of PGP, the most widely used email encryption software in the world. Zfone uses a new protocol called ZRTP, which has a better architecture than the other approaches to secure VoIP.

* Doesn't depend on signaling protocols, PKI, or any servers at all. Key negotiations are purely peer-to-peer through the media stream * Interoperates with any SIP/RTP phone, auto-detects if encryption is supported by other endpoint * Available as a "plugin" for existing soft VoIP clients, effectively converting them into secure phones * Available as an SDK for developers to integrate into their VoIP applications * IETF has published the protocol spec as RFC 6189, and source code is published

Tetsunari Iida, a former nuclear engineer who currently heads the Institute for Sustainable Energy Policies, says that the industry is dominated by a closely-knit nuclear establishment. Those who graduate from universities and graduate from schools with degrees in nuclear power engineering go on to work at power companies, energy-related manufacturers, or municipalities that host nuclear power stations. Everything comes down to personal networks, and who the graduating students go on to work for is largely influenced by the connections and interests of the students' professors. Regardless of whether the employers are public or private organizations, the newly inducted engineers are raised to become full-fledged members of the nuclear establishment.

Security researchers presenting at the Where 2.0 conference have revealed a hidden, secret iOS file that keeps a record of everywhere you've been. The record is synched to your PC and subsequently resynched to your other mobile devices. The file is not transmitted to Apple, but constitutes a substantial privacy breach if your PC or mobile device are lost or seized. The researchers, Alasdair Allan and Pete Warden, have released a free/open application called "iPhone Tracker" that allows you to retrieve the location data on your iOS device and examine it. They did not discover a comparable file on Android devices.

“Right now, it's just an illusion of security,” said Moxie Marlinspike, a security researcher who has repeatedly poked holes in the technical underpinnings of SSL. “Depending on what you think your threat is, you can trust it on varying levels, but fundamentally, it has some pretty serious problems.”

Just a month before a powerful earthquake and tsunami crippled the Fukushima Daiichi plant at the center of Japan’s nuclear crisis, government regulators approved a 10-year extension for the oldest of the six reactors at the power station despite warnings about its safety.

The regulatory committee reviewing extensions pointed to stress cracks in the backup diesel-powered generators at Reactor No. 1 at the Daiichi plant, according to a summary of its deliberations that was posted on the Web site of Japan’s nuclear regulatory agency after each meeting. The cracks made the engines vulnerable to corrosion from seawater and rainwater. The generators are thought to have been knocked out by the tsunami, shutting down the reactor’s vital cooling system.

We do not know their names, their faces, their families or their personal stories. Nobody really does. They are strangers, in a faraway land, doing the unthinkable. In Japan they have a name: The Fukushima 50. A coterie of nuclear plant employees - some reports indicate 50, others suggest four working rotations of 50 - who stayed behind while 700 of their co-workers were evacuated from the stricken Fukushima-Daiichi facility on the Japanese coast.

Five have been killed. Two are missing. Twenty-one have been injured in a struggle where, in the words of Japan's Prime Minister Naoto Kan, "retreat is unthinkable." The men understand the stakes. They know there is no turning back. One worker told a departing colleague he was prepared to die - that it was his job. Another informed his wife he wouldn't be coming home anytime soon.

The unfolding disaster at the Fukushima nuclear plant follows decades of falsified safety reports, fatal accidents and underestimated earthquake risk in Japan’s atomic power industry.

Nuclear engineers and academics who have worked in Japan’s atomic power industry spoke in interviews of a history of accidents, faked reports and inaction by a succession of Liberal Democratic Party governments that ran Japan for nearly all of the postwar period.

A Bash script aimed at making the Wireless Hacking process a lot easier.

The EFD (Electronic Flight Data) system rolled out at the Scottish and Oceanic Air Traffic Control (ATC) Centre at Glasgow Prestwick Airport has had difficulty handling complex inputs, according to people posting on an air traffic control forum.

"[Controllers] don't want to use this system, not because they like to have a whinge, but because they know it is neither safe, nor efficient enough to do the job," wrote one Prestwick controller, Arty-Ziff, on the Pprune forum in February. "This system should have been tested properly before it went into live operations."

A passenger managed to waltz past JFK's ramped-up security gantlet with three boxcutters in his carry-on luggage -- easily boarding an international flight while carrying the weapon of choice of the 9/11 hijackers, sources told The Post yesterday.

The stunning breach grounded the flight for three hours Saturday night and drew fury from Port Authority cops, who accused the Transportation Security Administration of being asleep on the job.

...

The TSA spokeswoman Davis insisted that the traveling public was not at risk.

"There have been a number of additional security layers that have been implemented on aircraft that would prevent someone from causing harm with boxcutters," she insisted.

Presumably, he didn't bring any toothpaste on board, so there was never any real danger.
