Cisco fixes serious denial-of-service flaws in wireless LAN controllers, other products

Cisco Systems has released patches to fix serious denial-of-service flaws in its Wireless LAN Controller (WLC) software, Cisco Adaptive Security Appliance (ASA) software and the Secure Real-Time Transport Protocol (SRTP) library that's used in many products.The Cisco WLC software contains two denial-of-service vulnerabilities, one of which is rated critical and could be exploited by an unauthenticated attacker through specially crafted HTTP requests sent to the device. This can cause a buffer overflow condition that, in addition to a device reload, might also allow for execution of arbitrary code on the device.To read this article in full or to leave a comment, please click here

But tablet has Intel's Skylake-based Core I processors, and it needed a cooling mechanism, and Acer didn't want fans in it.While announcing the tablet Thursday, Acer said it is the first fanless tablet with a Skylake Core I processor. The device doesn't use Intel's power-efficient Core M processors, which is offered in many Windows thin-and-lights and the new MacBook.The Acer device has a "closed-loop liquid system," which dissipates the heat as liquid floats through the system. The liquid cooling system takes up little space.To read this article in full or to leave a comment, please click here

No, Apple didn’t make $40 million mining gold from discarded iPhones

Jason Koebler at Motherboard has done the worlds of reading, writing and recycling a massive favor by clarifying – debunking, in many cases – a run-amok story from earlier this week that created the erroneous impression that Apple was profiting handsomely from the mining of millions of dollars worth of gold from old iGadgets. Koebler’s piece begins: You may have seen a viral headline floating around over the last few days: Apple recycled $40 million worth of gold last year, which was extracted from iPhones. Almost none of what was reported is true.To read this article in full or to leave a comment, please click here

Top drone startups find venture capital flying their way

With unmanned aerial vehicles (i.e., drones) here to stay, entrepreneurs are pouncing on the opportunity to safeguard people from having these flying machines drop in unexpectedly and venture capitalists are buying in. SkySafe, a San Diego startup formed last year by a team from MIT, UC San Diego, the Air Force Research Lab and more, says its goal is “to build safe, secure airspaces as a new wild west of drone development and innovation emerges.” The company this week announced it has raised seed funding, said to total $3 million, in a round led by Andreessen Horowitz. SkySafe’s possible customers would include prisons, stadiums and airports looking to keep their airspace safe by, if need be, downing intrusive drones after spotting them.To read this article in full or to leave a comment, please click here

You’ve been hit with ransomware. Now what?

Imagine waking up to an urgent 5 a.m. call: Something has taken over your corporate network and encrypted all of your data, and supposedly the only way to get it all back is to pay a significant sum to an anonymous third party using Bitcoin. While that scene might sound like something out of Hollywood, it is actually very real – and it’s exactly what several variants of ransomware are doing to organizations around the globe.Two recent appearances of ransomware in the news demonstrate that it is a problem that is growing in both volume and significance, as larger and larger organizations, some critical to public and social services, are impacted by an outbreak:To read this article in full or to leave a comment, please click here

IT salaries increase across 12 tech job categories

Salaries increase across 12 tech job categoriesImage by ThinkstockMondo's 2016-2017 IT Salary Guide points to steady increases in tech salaries across 12 verticals. The study points out that as technology influences every industry, the demand for STEM workers is only going to increase, with a projected 1.5 million open positions in STEM by the year 2020. If you are already in the technology field, or are hoping to break into it, it couldn't be a better time. Mondo tracks the salaries of popular technology jobs to see how the annual compensation range increases year over year and this most recent report shows increases in nearly every tech job evaluated; and for jobs that didn't increase in this report, they at least didn't show a decline in average salary either.

This tool can block ransomware on Mac OS X, for now

A security researcher has created a free security tool that can detect attempts by ransomware programs to encrypt files on users' Macs and then block them before they do a lot of damage.Called RansomWhere? the application is the creation of Patrick Wardle, director of research and development at security firm Synack. It's meant to detect and block the encryption of files by untrusted processes.The tool monitors users' home directories and detects when encrypted files are rapidly created inside them -- a telltale sign of ransomware activity.When such activity is detected, RansomWhere? determines the process responsible and suspends it. To limit false positives -- legitimate encryption programs being detected as ransomware -- the tool whitelists all applications signed by Apple and most of those that already exist on the computer when RansomWhere? is first installed.To read this article in full or to leave a comment, please click here

Jenkins as system job scheduler

Jenkins is an open software tool, typically used for continuous integration in software development. Network or system changes can be treated in a similar way as code changes are: developed, tested and deployed. Test frameworks are coming  to Network world (look at TODD) but are not popular yet.  Even without unit tests we can still use developer tools like Jenkins […]
