NSA collects nearly 5 billion cellphone location records per day | Ars Technica - 0 views

  • The Washington Post added another noteworthy finding to the growing pile of information leaked by former NSA contractor Edward Snowden: the NSA is collecting nearly five billion cellphone location records per day from across the world.
  • This gigantic data collection feeds a database that stores information on "hundreds of millions of devices," according to the documents obtained by
  • 27 terabytes

  • The paper spoke with an intelligence lawyer who continued to emphasize that this program focuses beyond the US, which seems to prevent the data from falling under the Fourth Amendment (unreasonable search and seizures).

NSA Is Tracking Mobile Phone Location On So Many People It Can't Handle The Data Storag... - 0 views

  • The NSA cannot know in advance which tiny fraction of 1 percent of the records it may need, so it collects and keeps as many as it can — 27 terabytes, by one account, or more than double the text content of the Library of Congress’s print collection.
  • NSA defends the program by saying that it uses the location data to find "unknown associates of known intelligence targets." Basically, it's tracking where everyone goes, just in case people end up spending time with people the NSA deems as being terrorists.
  • Elsewhere in the article, they quote NSA officials repeatedly saying that the program is "tuned to be looking outside the United States," but not saying it only collects info outside the US. Also, they make clear, once a person leaves the US, the NSA no longer believes the 4th Amendment applies to them, so their location is fair game in this giant database.. Asked for specific numbers, an NSA person said:

Ask Ethan #55: Could a Manned Mission to Mars Abort? - Starts With A Bang! - Medium - 0 views

  • No humans have ever traveled farther away from Earth than the crew of Apollo 13 did, as they circled around the far side of the Moon close to lunar apogee, achieving a maximum distance of 400,171 km above the Earth’s surface on April 15, 1970. But when the first manned spaceflight to another planet occurs, that record will be shattered, and in a mere matter of days.
  • The way we currently reach other worlds with our present technology — or any remote location in the Universe — involves three distinct stages:The initial launch, which overcomes the Earth’s gravitational binding energy and starts our spacecraft off with a reasonably large (on the order of a few km/s) velocity relative to the Earth’s motion around the Sun.On-board course corrections, where very small amounts of thrust accelerate the spacecraft to its optimal trajectory.And gravity assists, where we use the gravitational properties of other planets in orbit around the Sun to change our spacecraft’s velocity, either increasing or decreasing its speed with every encounter.It’s through the combination of these three actions that we can reach any location — if we’re patient and we plan properly — with only our current rocket technology.

      How we can do it now, if we plan right.
  • The initial launch is a very hard part right now. It takes a tremendous amount of resources to overcome the Earth’s gravitational pull, to accelerate a significant amount of mass to the Earth’s escape velocity, and to raise it all the way up through the Earth’s atmosphere.

  • The most optimal one for a one-way trip to Mars, for those of you wondering, that minimizes both flight time and the amount of energy needed, involves simply timing your launch right.

      The cheapest and the fastest. The one way ticket option.
  • When a planet orbits the Sun, there’s a lot of energy in that system, both gravitational energy and kinetic energy. When a third body interacts gravitationally as well, it can either gain some energy by stealing it from the Sun-planet system, or it can lose energy by giving it up to the Sun-planet system. The amount of energy performed by the spacecraft’s thrusters is often only 20% (or less) of the energy either gained-or-lost from the interaction!

Rent-to-own PCs surreptitiously captured users' most intimate moments | Ars Technica - 0 views

  • The software, known as PC Rental Agent, was developed by Pennsylvania-based DesignerWare. It was licensed by more than 1,617 rent-to-own stores in the US, Canada, and Australia to report the physical location of rented PCs. A feature known as Detective Mode also allowed licensees to surreptitiously monitor the activities of computer users. Managers of rent-to-own stores could use the feature to turn on webcams so anyone in front of the machine would secretly be recorded. Managers could also use the software to log keystrokes and take screen captures.
  • In some cases, webcam activations captured images of children, individuals not fully clothed, and people engaged in sexual activities, the complaint alleged. Rental agreements never disclosed the information that was collected, FTC lawyers said.
  • PC Rental Agent also had the capability to display fake registration pages for Microsoft Windows, Internet Explorer, Microsoft Office, and Yahoo Messenger. When customers entered their names, addresses, and other personal information in the forms, the data was sent to DesignerWare servers and then e-mailed to the rent-to-own licensees.

FBI surveillance malware in bomb threat case tests constitutional limits | Ars Technica - 0 views

  • The FBI has an elite hacker team that creates customized malware to identify or monitor high-value suspects who are adept at covering their tracks online, according to a published report.
  • as the capability to remotely activate video cameras and report users' geographic locations—is pushing the boundaries of constitutional limits on searches and seizures
  • Critics compare it to a physical search that indiscriminately seizes the entire contents of a home, rather than just those items linked to a suspected crime. Former US officials said the FBI uses the technique sparingly, in part to prevent it from being widely known.

  • "We have transitioned into a world where law enforcement is hacking into people’s computers, and we have never had public debate,” Christopher Soghoian, principal technologist for the American Civil Liberties Union, told The Washington Post, speaking of the case against Mo. "Judges are having to make up these powers as they go along."

NSA reportedly 'piggybacking' on Google advertising cookies to home in on surveillance ... - 0 views

  • US surveillance agency may be using Google's advertising cookies to track and "pinpoint" targets for government hacking and location-tracking. According to Snowden's leaked presentation slides, both the NSA and the British equivalent, the GCHQ, are using a Google-specific ad cookie (know as "PREF") as a way of homing in on specific surveillance targets. While Google's cookie doesn't contain personal information like a name or email address, it does contain numeric codes that uniquely identify a user's browser.
  • The report notes that the NSA doesn't use this technique to find suspicious activity amidst the massive flood of internet communication that takes place every day — instead, it uses it to home in on targets already under suspicion.

Active malware operation let attackers sabotage US energy industry | Ars Technica - 0 views

  • Researchers have uncovered a malware campaign that gave attackers the ability to sabotage the operations of energy grid owners, electricity generation firms, petroleum pipelines, and industrial equipment providers.

  • "This campaign follows in the footsteps of Stuxnet, which was the first known major malware campaign to target ICS systems," the Symantec report stated. "While Stuxnet was narrowly targeted at the Iranian nuclear program and had sabotage as its primary goal, Dragonfly appears to have a much broader focus with espionage and persistent access as its current objective with sabotage as an optional capability if required."

  • "The Dragonfly group is technically adept and able to think strategically," the Symantec report stated. "Given the size of some of its targets, the group found a 'soft underbelly' by compromising their suppliers, which are invariably smaller, less protected companies."

Mega Goes Legal, Issues Ultimatum Over Cyberlocker Report | TorrentFreak - 0 views

  • Mega was founded by Kim Dotcom but the site bears little resemblance to his now defunct Megaupload. Perhaps most importantly, Mega was the most-scrutinized file-hosting startup ever, so every single detail simply had to be squeaky clean. As a result the site took extensive legal advice to ensure that it complies with every single facet of the law. Nevertheless, NetNames took the decision to put Mega in its report anyway, bundling the site in with what are described as some of the market’s most dubious players. This was not received well by Mega CEO Graham Gaylard. In a TorrentFreak article he demanded a full apology from NetNames and Digital Citizens Alliance and for his company to be withdrawn from the report. Failure to do so would result in “further action”, he said.
  • “Mega’s legal counsel has written to NetNames, Digital Citizens Alliance and The Internet Technology & Innovation Foundation (ITIF) stating that the report is clearly defamatory,” Mega CEO Graham Gaylard told TorrentFreak this morning.
  • Firstly, Mega’s legal team are now demanding the removal of the report, and all references to it, from all channels under the respondents’ control. They also demand that further circulation of the report must be discontinued and no additional references to it should be made in public.

  • Finally, Mega is demanding a full public apology “to its satisfaction” to be published on the homepages of the respondents’ websites.
  • Mega has given the companies seven days to comply with the above requests.
