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.

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.

One Family Suffering Through Years-Long Trolling Campaign

blottsie writes: Since 2010, the Straters have been under assault from an online campaign of ever-increasing harassment — prank deliveries, smear attacks, high-profile hacks, and threats of violence against schools and law enforcement officials in their name — and it’s slowly torn them apart. Masterminding it all is a teenage Lizard Squad hacker from Finland, at war with their son, Blair, over a seemingly minor dispute. “When the family started getting notices about their utilities being disconnected, they realized things were escalating out of control. Utility provider Commonwealth Edison once called the house to iron out the details about a request to have the power turned off after a supposed move. Something similar happened with their trash service. On Halloween 2013, Comcast shut off their cable and Internet service.” Read more of this story at Slashdot.

Understanding the Antikythera Mechanism

szczys writes: We attribute great thinking to ancient Greece. This is exemplified by the Antikythera Mechanism. Fragments of the mechanism were found in a shipwreck first discovered in 1900 and visited by researchers several times over the next century. It is believed to be a method of tracking the calendar and is the first known example of what are now common-yet-complicated engineering mechanisms like the differential gear. A few working reproductions have been produced and make it clear that whomever designed this had an advanced understanding of complex gear ratios and their ability to track the passage of time and celestial bodies. Last year research by two scientists suggested that the device might be much older than previously thought. Read more of this story at Slashdot.
