Critical Zen Cart Vulnerability Could Spell Black Friday Disaster For Shoppers

Mark Wilson writes: It’s around this time of year, with Black Friday looming and Christmas just around the corner, that online sales boom. Today security firm High-Tech Bridge has issued a warning to retailers and shoppers about a critical vulnerability in the popular Zen Cart shopping management system. High-Tech Bridge has provided Zen Cart with full details of the security flaw which could allow remote attackers to infiltrate web servers and gain access to customer data. Servers running Zen Cart are also at risk of malware, meaning that hundreds of thousands of ecommerce sites pose a potential danger. Technical details of the vulnerability are not yet being made public, but having notified Zen Cart of the issue High-Tech Bridge says the date of full public disclosure is 16 December.

Scientists Produce Graphene 100 Times Cheaper Than Ever Before

Zothecula writes that researchers at the University of Glasgow have found a way to produce large sheets of graphene 100 times more cheaply than previous methods. Gizmag reports: “Since first being synthesized by Andre Geim and Kostya Novoselov at the University of Manchester in 2004, there has been an extensive effort to exploit the extraordinary properties of graphene. However the cost of graphene in comparison to more traditional electronic materials has meant that its uptake in electronic manufacturing has been slow. Now researchers at the University of Glasgow have discovered a way to create large sheets of graphene using the same type of cheap copper used to manufacture lithium-ion batteries.” Read more of this story at Slashdot.

Managing a 100-percent renewable grid, without batteries

(credit: US DOE ) Stanford researcher Mark Jacobson likes to take current thinking about renewable energy and supersize it. Rather than aiming for 50 percent renewables, like California is , he has analyzed what it would take for each of the 50 states to go fully renewable . It would apparently involve so many offshore wind turbines that hurricanes headed toward the States would be suppressed. Now, he and a few collaborators are back with a more detailed look at how to manage the grid stability issues that come with large amounts of intermittent generators, like photovoltaic panes and wind turbines. Normally, issues of intermittency are expected to be handled by fossil fuel power and batteries. But the new analysis suggests we don’t need any of that—and we don’t need biofuels or nuclear, either. Instead, it suggests we could manage a 100-percent renewable grid through a combination of hydrogen production and heat storage. None of this is entirely new. People have been talking about generating hydrogen from renewable energy for years—with a fuel cell, it can be used to power cars or generate electricity as needed. And the paper cites an existing community that’s already using solar energy to generate heat that’s stored under ground. But, as with Jacobson’s past analyses, they are taken to new scales here.

Iranian military spear-phish of State Department employees detected first by Facebook

The Facebook and email accounts of US State Department officials focused on Iran were hacked, and possibly used to gather data about US-Iranian dual citizens in Iran. More details have emerged about the hacking the computers of US State Department and other government employees, first revealed earlier this month in a Wall Street Journal report . The intrusions by hackers purported to be associated with the Iranian Revolutionary Guard may be tied to the arrest of an Iranian-American businessman in Tehran in October and other arrests of dual citizens in Iran. The attackers used compromised social media accounts of junior State Department staff as part of a “phishing” operation that compromised the computers of employees working in the State Department’s Office of Iranian Affairs and Bureau of Near Eastern Affairs and computers of some journalists. The first warning of the attacks came from Facebook, which alerted some of the affected users that their accounts had been compromised by a state-sponsored attack, the New York Times reports . The Iranian Revolutionary Guard hackers used the access to identify the victims’ contacts and build “spear-phishing” attacks that gave them access to targeted individuals’ e-mail accounts. The attack “was very carefully designed and showed the degree to which they understood which of our staff was working on Iran issues now that the nuclear deal is done,” an unnamed senior US official told the Times . This most recent attack, which came after a brief period of little or no Iranian activity against US targets over the summer according to data from Check Point and iSight Partners, was a change from tactics previously associated with Iranian hackers. Earlier attacks attributed to Iran were focused on taking financial services companies’ websites offline  and destroying data—such as in the attack attack on casino company Las Vegas Sands Corp. last year after its majority owner called for a nuclear attack on Iran. These attacks may not have been carried out by the Iranian government but by Iranian or pro-Iranian “hacktivists.” The State Department attack, however, was more subtle and aimed at cyber-espionage rather than simple vengeance—bearing hallmarks of tactics attributed to Chinese state-sponsored hackers.

New Wearable Tech Translates Sign Language Into Text

An anonymous reader writes: A new wearable technology developed by a team of biomedical engineers at Texas A&M University seeks to aid seamless communication between deaf people who use sign language and those who do not understand it. The arm device contains a network of sensors which track hand movements, as well as the electromyography (EMG) signals generated by the muscles in the wrist, and process and translate the different signals into text in real-time.The prototype currently uses Bluetooth to translate the sign language to a computer or smartphone.

Even the Dumbest Ransomware Is Almost Unremovable On Smart TVs

An anonymous reader writes: Apparently even the easiest-to-remove ransomware is painfully hard to uninstall from smart TVs, if they’re running on the Android TV platform, and many are. This didn’t happen in a real-world scenario (yet), and was only a PoC test by Symantec. The researcher managed to remove the ransomware only because he enabled the Android ADB tool beforehand, knowing he would infect the TV with the ransomware. “Without this option enabled, and if I was less experienced user, I’d probably still be locked out of my smart TV, making it a large and expensive paper weight, ” said the researcher.
