The NSA and Britain's GCHQ hacked the world's biggest SIM card maker to harvest the encryption keys needed to silently and effortlessly eavesdrop on potentially millions of people. That's according to documents obtained by surveillance whistleblower Edward Snowden and leaked to the web on Thursday. "Wow. This is huge – it's one of the most significant findings of the Snowden files so far," computer security guru Bruce Schneier told The Register this afternoon. "We always knew that they would occasionally steal SIM keys. But all of them? The odds that they just attacked this one firm are extraordinarily low and we know the NSA does like to steal keys where it can." The damning slides, published by Snowden's chums at The Intercept, detail the activities of the as-yet unheard-of Mobile Handset Exploitation Team (MHET), run by the US and UK. The group targeted Gemalto, which churns out about two billion SIM cards each year for use around the world, and targeted it in an operation dubbed DAPINO GAMMA.

Gemalto's hacking may also bring into question some of its other security products as well. The company supplies chips for electronic passports issued by the US, Singapore, India, and many European states, and is also involved in the NFC and mobile banking sector. It's important to note that this is useful for tracking the phone activity of a target, but the mobile user can still use encryption on the handset itself to ensure that some communications remain private. "Ironically one of your best defenses against a hijacked SIM is to use software encryption," Jon Callas, CTO of encrypted chat biz Silent Circle told The Register. "In our case there's a TCP/IP cloud between Alice and Bob and that can deal with compromised routers along the path as well as SIM issues, and the same applies to similar mobile software."

On Wednesday the UK government admitted that its intelligence agencies had in fact broken the ECHR when spying on communications between lawyers and those suing the British state, so GCHQ might want to reconsider that statement.

When I first started reading Ars Technica, performance of a processor was measured in megahertz, and the major manufacturers were rushing to squeeze as many of them as possible into their latest silicon. Shortly thereafter, however, the energy needs and heat output of these beasts brought that race crashing to a halt. More recently, the number of processing cores rapidly scaled up, but they quickly reached the point of diminishing returns. Now, getting the most processing power for each Watt seems to be the key measure of performance. None of these things happened because the companies making processors ran up against hard physical limits. Rather, computing power ended up being constrained because progress in certain areas—primarily energy efficiency—was slow compared to progress in others, such as feature size. But could we be approaching physical limits in processing power? In this week's edition of Nature, The University of Michigan's Igor Markov takes a look at the sorts of limits we might face.

"When NSA whistleblower Edward Snowden came forth last year with U.S. government spying secrets, it didn't take long to realize that some of the information revealed could bring on serious repercussions — not just for the U.S. government, but also for U.S.-based companies. The latest to feel the hit? None other than Apple, and in a region the company has been working hard to increase market share: China. China, via state media, has today declared that Apple's iPhone is a threat to national security — all because of its thorough tracking capabilities. It has the ability to keep track of user locations, and to the country, this could potentially reveal "state secrets" somehow. It's being noted that the iPhone will continue to track the user to some extent even if the overall feature is disabled. China's iPhone ousting comes hot on the heels of Russia's industry and trade deeming AMD and Intel processors to be untrustworthy. The nation will instead be building its own ARM-based "Baikal" processor.

AMERICAN AND BRITISH spies hacked into the internal computer network of the largest manufacturer of SIM cards in the world, stealing encryption keys used to protect the privacy of cellphone communications across the globe, according to top-secret documents provided to The Intercept by National Security Agency whistleblower Edward Snowden. The hack was perpetrated by a joint unit consisting of operatives from the NSA and its British counterpart Government Communications Headquarters, or GCHQ. The breach, detailed in a secret 2010 GCHQ document, gave the surveillance agencies the potential to secretly monitor a large portion of the world’s cellular communications, including both voice and data. The company targeted by the intelligence agencies, Gemalto, is a multinational firm incorporated in the Netherlands that makes the chips used in mobile phones and next-generation credit cards. Among its clients are AT&T, T-Mobile, Verizon, Sprint and some 450 wireless network providers around the world. The company operates in 85 countries and has more than 40 manufacturing facilities. One of its three global headquarters is in Austin, Texas and it has a large factory in Pennsylvania. In all, Gemalto produces some 2 billion SIM cards a year. Its motto is “Security to be Free.”

With these stolen encryption keys, intelligence agencies can monitor mobile communications without seeking or receiving approval from telecom companies and foreign governments. Possessing the keys also sidesteps the need to get a warrant or a wiretap, while leaving no trace on the wireless provider’s network that the communications were intercepted. Bulk key theft additionally enables the intelligence agencies to unlock any previously encrypted communications they had already intercepted, but did not yet have the ability to decrypt.

Leading privacy advocates and security experts say that the theft of encryption keys from major wireless network providers is tantamount to a thief obtaining the master ring of a building superintendent who holds the keys to every apartment. “Once you have the keys, decrypting traffic is trivial,” says Christopher Soghoian, the principal technologist for the American Civil Liberties Union. “The news of this key theft will send a shock wave through the security community.”

In but the latest in a continuing saga of big tech tracking and surveillance stories which should serve to convince us all we are living in the beginning phases of a Minority Report style tracking and pansophical "pre-crime" system, it's now confirmed that the world's most powerful tech company and search tool will always find a way to keep your location data. The Associated Press sought the help of Princeton researchers to prove that while Google is clear and upfront about giving App users the ability to turn off or "pause" Location History on their devices, there are other hidden means through which it retains the data.

According to the AP report: Google says that will prevent the company from remembering where you’ve been. Google’s support page on the subject states: “You can turn off Location History at any time. With Location History off, the places you go are no longer stored.” That isn’t true. Even with Location History paused, some Google apps automatically store time-stamped location data without asking. For example, Google stores a snapshot of where you are when you merely open its Maps app. Automatic daily weather updates on Android phones pinpoint roughly where you are. And some searches that have nothing to do with location, like “chocolate chip cookies,” or “kids science kits,” pinpoint your precise latitude and longitude — accurate to the square foot — and save it to your Google account. The issue directly affects around two billion people using Google's Android operating software and iPhone users relying on Google maps or a simple search. Among the computer science researchers at Princeton conducting the tests is Jonathan Mayer, who told the AP, “If you’re going to allow users to turn off something called ‘Location History,’ then all the places where you maintain location history should be turned off,” and added, “That seems like a pretty straightforward position to have.”

The encryption debate dates back to Clinton administration proposals for the “clipper chip” and mandatory deposit of decryption keys. But that debate reached new prominence in connection with the FBI’s efforts to compel Apple to decrypt the phone of a dead terrorist in the San Bernardino case. A new study by the National Academies of Sciences, Engineering, and Medicine tries to shed some light, and turn down the heat, in the debate over whether government agencies should be provided access to plaintext versions of encrypted communications and other data. FBI and other law enforcement officials, and some intelligence officials, have argued that in the face of widespread encryption provided by smart phones, messaging apps, and other devices and software, the internet is “going dark.” These officials warn that encryption is restricting their access to information needed for criminal and national security investigations, arguing that they need a reliable, timely and scalable way to access it. Critics have raised legal and practical objections that regulations to ensure government access would pose unacceptable risks to privacy and civil liberties and undermine computer security in the face of rising cyber threats, and may be less necessary given the wider availability of data and alternative means of obtaining access to encrypted data. As the encryption debate has become increasingly polarized with participants on all sides making sweeping, sometimes absolutist, assertions, the new National Academies’ report doesn’t purport to tell anyone what to do, but rather provides a primer on the relevant issues.

As traders focused on bank earnings and the outlook for global growth, NBC News wrested the market's attention back toward Facebook by publishing a report on what appears to be the largest leak of internal documents since the data privacy scandal that has dogged the company for more than a year erupted with the first reports about Cambridge Analytica's 'improper' leveraging of Facebook user data to influence elections.

Some 4,000 pages of documents shared with the network news organization by a journalist affiliated with the ICIJ, the same organization that helped bring us the Panama Papers leaks, revealed that Facebook had employed sensitive user data as a bargaining chip to attract major advertisers and close other deals between 2011 and 2015, when the company was struggling to cement its business model following its botched 2012 IPO.

Facebook essentially offered companies like Amazon unfettered access to its data in exchange for agreeing to advertise on Facebook's platform, according to the documents, only a small fraction of which have been previously reported on. All of this was happening at a time when the company publicly professed to bee safeguarding user data.
