Black Hat Researchers Actively Trying To Deanonymize Tor Users 79

Posted by Soulskill
from the good-research-vs-bad-research dept.
An anonymous reader writes: Last week, we discussed news that a presentation had been canceled for the upcoming Black Hat security conference that involved the Tor Project. The researchers involved hadn't made much of an effort to disclose the vulnerability, and the Tor Project was scrambling to implement a fix. Now, the project says it's likely these researchers were actively attacking Tor users and trying to deanonymize them. "On July 4 2014 we found a group of relays that we assume were trying to deanonymize users. They appear to have been targeting people who operate or access Tor hidden services. The attack involved modifying Tor protocol headers to do traffic confirmation attacks. ...We know the attack looked for users who fetched hidden service descriptors, but the attackers likely were not able to see any application-level traffic (e.g. what pages were loaded or even whether users visited the hidden service they looked up). The attack probably also tried to learn who published hidden service descriptors, which would allow the attackers to learn the location of that hidden service." They also provide a technical description of the attack, and the steps they're taking to block such attacks in the future.

Senate Bill Would Ban Most Bulk Surveillance 173

Posted by Soulskill
from the assuming-they-can-pass-anything dept.
An anonymous reader writes: Today Senator Patrick Leahy (D-VT) introduced a bill that would ban bulk collection of telephone records and internet data for U.S. citizens. This is a stronger version of the legislation that passed the U.S. House in May, and it has support from the executive branch as well. "The bill, called the USA Freedom Act, would prohibit the government from collecting all information from a particular service provider or a broad geographic area, such as a city or area code, according to a release from Leahy's office. It would expand government and company reporting to the public and reform the Foreign Intelligence Surveillance Court, which reviews NSA intelligence activities. Both House and Senate measures would keep information out of NSA computers, but the Senate bill would impose stricter limits on how much data the spy agency could seek."

UrsaMajor987 (3604759) writes I have a Asus Transformer tablet that I dropped on the floor. There is no obvious sign of damage but It will no longer boot. Good excuse to get a newer model. I intend to sell it for parts (it comes with an undamaged keyboard) or maybe just toss it. I want to remove all my personal data. I removed the flash memory card but what about the other storage? I know how to wipe a hard drive, but how do you wipe a tablet? If you were feeling especially paranoid, but wanted to keep the hardware intact for the next user, what would you do?

Private Data On iOS Devices Not So Private After All 100

Posted by timothy
from the it's-totally-intuitive dept.
theshowmecanuck (703852) writes with this excerpt from Reuters summarizing the upshot of a talk that Jonathan Zdziarski gave at last weekend's HOPE conference: Personal data including text messages, contact lists and photos can be extracted from iPhones through previously unpublicized techniques by Apple Inc employees, the company acknowledged this week. The same techniques to circumvent backup encryption could be used by law enforcement or others with access to the 'trusted' computers to which the devices have been connected, according to the security expert who prompted Apple's admission. Users are not notified that the services are running and cannot disable them, Zdziarski said. There is no way for iPhone users to know what computers have previously been granted trusted status via the backup process or block future connections. If you'd rather watch and listen, Zdziarski has posted a video showing how it's done.

FBI Studied How Much Drones Impact Your Privacy -- Then Marked It Secret 139

Posted by timothy
from the awfully-suggestive dept.
v3rgEz writes When federal agencies adopt new technology, they're required by law to do Privacy Impact Assessments, which is exactly what the FBI did regarding its secretive drone program. The PIAs are created to help the public and federal government assess what they're risking through the adoption of new technology. That part is a little trickier, since the FBI is refusing to release any of the PIA on its drone project, stating it needs to be kept, er, private to protect national security.

hypnosec writes: The government of Russia has announced a ~$110,000 bounty to anyone who develops technology to identify users of Tor, an anonymising network capable of encrypting user data and hiding the identity of its users. The public description (in Russian) of the project has been removed now and it only reads "cipher 'TOR' (Navy)." The ministry said it is looking for experts and researchers to "study the possibility of obtaining technical information about users and users' equipment on the Tor anonymous network."

From the article: Sony has finally agreed to a preliminary settlement of $15m, which may be able to appease most of the customers that suffered from this attack. The PlayStation Network users that did not partake in the "Welcome Back" program that Sony unveiled shortly after their online services were brought back will be able to choose from two of several options for compensation: One PlayStation 3 or PlayStation Portable game selected from a list of 14 games; three PlayStation 3 themes selected from a list of six themes; or a three-month subscription to PlayStation Plus free of charge. Claiming these benefits will be done on a first come, first serve basis ...The settlement isn't just about free games or services. Customers with documented identity theft charges are eligible for up to $2,500 per claim.

Dutch Court Says Government Can Receive Bulk Data from NSA 109

from the convenient-loophole dept.
jfruh (300774) writes Dutch law makes it illegal for the Dutch intelligence services to conduct mass data interception programs. But, according to a court in the Hague, it's perfectly all right for the Dutch government to request that data from the U.S.'s National Security Agency, and doing so doesn't violate any treaties or international law.

Dropbox Head Responds To Snowden Claims About Privacy 176

Posted by samzenpus
from the protect-ya-neck dept.
First time accepted submitter Carly Page writes When asked for its response to Edward Snowden's claims that "Dropbox is hostile to privacy", Dropbox told The INQUIRER that users concerned about privacy should add their own encryption. The firm warned however that if users do, not all of the service's features will work. Head of Product at Dropbox for Business Ilya Fushman says: "We have data encrypted on our servers. We think of encryption beyond that as a users choice. If you look at our third-party developer ecosystem you'll find many client-side encryption apps....It's hard to do things like rich document rendering if they're client-side encrypted. Search is also difficult, we can't index the content of files. Finally, we need users to understand that if they use client-side encryption and lose the password, we can't then help them recover those files."

Verizon's Offer: Let Us Track You, Get Free Stuff 75

Posted by samzenpus
from the do-your-worst dept.
mpicpp points out a new program from Verizon that is perfect if you don't mind being tracked. Are you comfortable having your location and Web browsing tracked for marketing purposes? If so, Verizon's got a deal for you. The wireless giant announced a new program this week called 'Smart Rewards' that offers customers credit card-style perks like discounts for shopping, travel and dining. You accrue points through the program by doing things like signing onto the Verizon website, paying your bill online and participating in the company's trade-in program. Verizon emphasizes that the data it collects is anonymized before it's shared with third parties. The program is novel in that offers Verizon users some compensation for the collection of their data, which has become big business for telecom and tech companies. Some privacy advocates have pushed data-collecting companies to reward customers for their personal information in the interest of transparency.

Jason Koebler writes: According to plaintiffs in a class-action lawsuit against Google, personal information about you and your browsing, email, and app-using habits that is regularly sent between apps on you Android phone is harming your battery life. As odd as it sounds, this minor yet demonstrable harm is what will allow their lawsuit to go forward. A federal judge ruled that the claim "requires a heavily and inherently fact-bound inquiry." That means there's a good chance we're about to get a look into the ins and outs of Google's advertising backbone: what information is shared with whom, and when.

EFF Releases Wireless Router Firmware For Open Access Points 56

Posted by Soulskill
from the secure-is-as-secure-does dept.
klapaucjusz writes: The EFF has released an experimental router firmware designed make it easy to deploy open (password-less) access points in a secure manner. The EFF's firmware is based on the CeroWRT fork of OpenWRT, but appears to remove some of its more advanced routing features. The EFF is asking for help to further develop the firmware. They want the open access point to co-exist on the same router as your typical private and secured access point. They want the owner to be able to share bandwidth, but with a cap, so guests don't degrade service for the owner. They're also looking to develop a network queueing, a minimalist web UI, and an auto-update mechanism. The EFF has also released the beta version of a plug-in called Privacy Badger for Firefox and Chrome that will prevent online advertisers from tracking you.

Black Hat Presentation On Tor Cancelled, Developers Working on Bug Fix 52

Posted by Soulskill
from the you-can't-say-that-on-television dept.
alphadogg writes A presentation on a low-budget method to unmask users of a popular online privacy tool Tor will no longer go ahead at the Black Hat security conference early next month. The talk was nixed by the legal counsel with Carnegie Mellon's Software Engineering Institute after a finding that materials from researcher Alexander Volynkin were not approved for public release, according to a notice on the conference's website. Tor project leader Roger Dingledine said, "I think I have a handle on what they did, and how to fix it. ... Based on our current plans, we'll be putting out a fix that relays can apply that should close the particular bug they found. The bug is a nice bug, but it isn't the end of the world." Tor's developers were "informally" shown materials about the bug, but never saw any details about what would be presented in the talk.

Exodus Intelligence Details Zero-Day Vulnerabilities In Tails OS 132

Posted by timothy
from the compared-to-what? dept.
New submitter I Ate A Candle (3762149) writes Tails OS, the Tor-reliant privacy-focused operating system made famous by Edward Snowden, contains a number of zero-day vulnerabilities that could be used to take control of the OS and execute code remotely. At least that's according to zero-day exploit seller Exodus Intelligence, which counts DARPA amongst its customer base. The company plans to tell the Tails team about the issues "in due time", said Aaron Portnoy, co-founder and vice president of Exodus, but it isn't giving any information on a disclosure timeline. This means users of Tails are in danger of being de-anonymised. Even version 1.1, which hit public release today (22 July 2014), is affected. Snowden famously used Tails to manage the NSA files. The OS can be held on a USB stick and leaves no trace once removed from the drive. It uses the Tor network to avoid identification of the user, but such protections may be undone by the zero-day exploits Exodus holds.

The Loophole Obscuring Facebook and Google's Transparency Reports 18

Posted by samzenpus
from the fuzzy-math dept.
Jason Koebler writes The number of law enforcement requests coming from Canada for information from companies like Facebook and Google are often inaccurate thanks to a little-known loophole that lumps them in with U.S. numbers. For example, law enforcement and government agencies in Canada made 366 requests for Facebook user data in 2013, according to the social network's transparency reports. But that's not the total number. An additional 16 requests are missing, counted instead with U.S. requests thanks to a law that lets Canadian agencies make requests with the U.S. Department of Justice.

Activist Group Sues US Border Agency Over New, Vast Intelligence System 82

Posted by samzenpus
from the lets-see-what-you-have-there dept.
An anonymous reader writes with news about one of the latest unanswered FOIA requests made to the Department of Homeland Security and the associated lawsuit the department's silence has brought. The Electronic Privacy Information Center (EPIC) has sued the United States Customs and Border Protection (CBP) in an attempt to compel the government agency to hand over documents relating to a relatively new comprehensive intelligence database of people and cargo crossing the US border. EPIC's lawsuit, which was filed last Friday, seeks a trove of documents concerning the 'Analytical Framework for Intelligence' (AFI) as part of a Freedom of Information Act (FOIA) request. EPIC's April 2014 FOIA request went unanswered after the 20 days that the law requires, and the group waited an additional 49 days before filing suit. The AFI, which was formally announced in June 2012 by the Department of Homeland Security (DHS), consists of "a single platform for research, analysis, and visualization of large amounts of data from disparate sources and maintaining the final analysis or products in a single, searchable location for later use as well as appropriate dissemination."

Researcher Finds Hidden Data-Dumping Services In iOS 98

Posted by samzenpus
from the don't-take-my-data-bro dept.
Trailrunner7 writes There are a number of undocumented and hidden features and services in Apple iOS that can be used to bypass the backup encryption on iOS devices and remove large amounts of users' personal data. Several of these features began as benign services but have evolved in recent years to become powerful tools for acquiring user data.

Jonathan Zdziarski, a forensic scientist and researcher who has worked extensively with law enforcement and intelligence agencies, has spent quite a bit of time looking at the capabilities and services available in iOS for data acquisition and found that some of the services have no real reason to be on these devices and that several have the ability to bypass the iOS backup encryption. One of the services in iOS, called mobile file_relay, can be accessed remotely or through a USB connection can be used to bypass the backup encryption. If the device has not been rebooted since the last time the user entered the PIN, all of the data encrypted via data protection can be accessed, whether by an attacker or law enforcement, Zdziarski said.

Ars Editor Learns Feds Have His Old IP Addresses, Full Credit Card Numbers 217

Posted by samzenpus
from the no-stone-left-unturned dept.
mpicpp writes with the ultimate results of Ars's senior business editor Cyrus Farivar's FOIA request. In May 2014, I reported on my efforts to learn what the feds know about me whenever I enter and exit the country. In particular, I wanted my Passenger Name Records (PNR), data created by airlines, hotels, and cruise ships whenever travel is booked. But instead of providing what I had requested, the United States Customs and Border Protection (CBP) turned over only basic information about my travel going back to 1994. So I appealed—and without explanation, the government recently turned over the actual PNRs I had requested the first time.

The 76 new pages of data, covering 2005 through 2013, show that CBP retains massive amounts of data on us when we travel internationally. My own PNRs include not just every mailing address, e-mail, and phone number I've ever used; some of them also contain: The IP address that I used to buy the ticket, my credit card number (in full), the language I used, and notes on my phone calls to airlines, even for something as minor as a seat change.
