Pod2g Confirms IOS 6, IOS 6.1 Beta 4 Untethered Jailbreak

hypnosec writes “Well known iOS security researcher Pod2g has confirmed that a working untethered iOS 6 jailbreak is ready and would be released as soon as iOS 6.1 GM is released. In an interview with iDigitalTimes, the security researcher has revealed that they are already in possession of a functional untethered iOS 6 and iOS 6.1 beta 4 jailbreak and majority of the work has been done by @planetbeing and @pimskeks. “6.0 is jailbroken, 6.1 beta 4 also. Now we are waiting 6.1 to confirm and release,” said the researcher. He said that the jailbreak would have been possible without him as he came into the iOS 6 jailbreak scene at a later stage and provided pointers that pushed the other researchers to the maximum.” Read more of this story at Slashdot.

With MS Research Help, UN Attempts To Model All of Earth’s Ecosystems

An anonymous reader writes “Microsoft Research and UN scientists have teamed up to build the first general-purpose computer model of whole ecosystems across the entire world. The project was detailed in a recent Nature article [note: yet another expensively paywalled original article] titled ‘Ecosystems: Time to model all life on Earth.'” Read more of this story at Slashdot.

Credit Card Swipe Fees Begin Sunday In USA

An anonymous reader writes “A speedbump on the road to a cash-free economy will go into effect Sunday in the USA, as retailers in 40 states will have the option of passing along a surcharge to customers who pay with credit cards. The so-called swipe fees arose from the settlement of a seven-year lawsuit filed by retailers against Visa, Mastercard, and big banks, who collect an electronic processing fee averaging 1.5 to 3 percent on transactions involving credit cards. The banks naturally have opposed the consumer surcharges, preferring that the extra costs to be passed along in the form of higher prices. Consumers in ten states (California, Colorado, Connecticut, Florida, Kansas, Maine, Massachusetts, New York, Oklahoma, Texas) won’t be affected, since laws in those states forbid the practice (it seems that gasoline station owners here in Massachusetts got a different memo, though). Also, the surcharges won’t be collected for debit or prepaid cards.” Read more of this story at Slashdot.

BitTorrent Launches Dropbox Alternative

redletterdave writes “On Friday morning, BitTorrent launched the alpha test of a new, free public service called BitTorrent Sync, which allows users to securely back up and sync files over the Web using BitTorrent’s platform. Unlike competing services such as Box or Dropbox, BitTorrent Sync doesn’t store files on remote servers (which means that no third party has access to one’s files), and also has no storage limits other than what your devices can hold.” Read more of this story at Slashdot.

Secret backdoors found in firewall, VPN gear from Barracuda Networks

A variety of firewall, VPN, and spam filtering gear sold by Barracuda Networks contains undocumented backdoor accounts that allow people to remotely log in and access sensitive information, researchers with an Austrian security firm have warned. The SSH, or secure shell, backdoor is hardcoded into “multiple Barracuda Networks products” and can be used to gain shell access to vulnerable appliances, according to an advisory published Thursday by SEC Consult Vulnerability Lab. “This functionality is entirely undocumented and can only be disabled via a hidden ‘expert options’ dialog,” the advisory states. The boxes are configured to listen for SSH connections to the backdoor accounts and will accept the username “product” with no Update: a “very weak” password to log in and gain access to the device’s MySQL database. While the backdoors can be accessed by only a small range of IP addresses, many of them belong to entities other than Barracuda. Read 4 remaining paragraphs | Comments

Grammar badness makes cracking harder the long password

Comparison of the size of password search space when treating the password as a sequence of characters or words, or as words generated by grammatical structure. Rao,et al. When it comes to long phrases used to defeat recent advances in password cracking, bigger isn’t necessarily better, particularly when the phrases adhere to grammatical rules. A team of Ph.D. and grad students at Carnegie Mellon University and the Massachusetts Institute of Technology have developed an algorithm that targets passcodes with a minimum number of 16 characters and built it into the freely available John the Ripper cracking program. The result: it was much more efficient at cracking passphrases such as “abiggerbetter password” or “thecommunistfairy” because they followed commonly used grammatical rules—in this case, ordering parts of speech in the sequence “determiner, adjective, noun.” When tested against 1,434 passwords containing 16 or more characters, the grammar-aware cracker surpassed other state-of-the-art password crackers when the passcodes had grammatical structures, with 10 percent of the dataset cracked exclusively by the team’s algorithm. The approach is significant because it comes as security experts are revising password policies to combat the growing sophistication of modern cracking techniques which make the average password weaker than ever before . A key strategy in making passwords more resilient is to use phrases that result in longer passcodes. Still, passphrases must remain memorable to the end user, so people often pick phrases or sentences. It turns out that grammatical structures dramatically narrow the possible combinations and sequences of words crackers must guess. One surprising outcome of the research is that the passphrase “Th3r3 can only b3 #1!” (with spaces removed) is one order of magnitude weaker than “Hammered asinine requirements” even though it contains more words. Better still is “My passw0rd is $uper str0ng!” because it requires significantly more tries to correctly guess. Read 9 remaining paragraphs | Comments

Swiss Federal Lab Claims New World Record For Solar Cell Efficiency

Zothecula writes “Scientists based at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have set a new efficiency record for thin-film copper indium gallium (di)selenid (or CIGS) based solar cells on flexible polymer foils, reaching an efficiency of 20.4 percent. This is an increase from a previous record of 18.7 percent set by the team back in 2011.” Read more of this story at Slashdot.

Replicating Hardest Known Biomaterial Could Improve Solar Cells and Batteries

cylonlover writes “Inspired by the tough teeth of a marine snail and the remarkable process by which they form, assistant professor David Kisailus at the University of California, Riverside is working toward building cheaper, more efficient nanomaterials. By achieving greater control over the low-temperature growth of nanocrystals (abstract), his research could improve the performance of solar cells and lithium-ion batteries, lead to higher-performance materials for car and airplane frames, and help develop abrasion-resistant materials that could be used for anything from specialized clothing to dental drills.” Read more of this story at Slashdot.
