A new kind of vulnerability popped up recently, one that lets hackers stick a USB thumb drive into a computer -- even if it's logged-off or locked -- type out a bit of attack code and steal whatever data they want.

In an effort to avoid this type of cyberattack, Microsoft issued its monthly software patches today and included a fix for this Windows vulnerability called MS13-027. This vulnerability lets a hacker get into the computer with a thumb drive and take over administrative privileges.

A suspected security hole affecting a handful of Samsung smartphones could give apps access to user data and leave the handset vulnerable to malicious apps and bricking, according to a developer.

The vulnerability, which was discovered and detailed by an XDA member with the handle "alephzain," lies in Exynos 4, the ARM-based system-on-chip typically found in Samsung smartphones and tablets. Alephzain developed an exploit he said bypasses the system permissions, allowing any app to extract data from the device's RAM or inject malicious code into the kernel.

Alephzain said that he stumbled upon the vulnerability while trying … Read more

After reports surfaced of its Chrome browser causing crashes on some of Apple's new MacBook systems, Google has publicly acknowledged the issue, claiming a workaround is immediately available and a true fix is in the works.

Owners of Apple's new MacBook Air had been experiencing persistent kernel panics on their systems, which after investigation were found to be rooted in actions like closing tabs and otherwise managing windows in Google's Chrome Web browser. Unfortunately, being kernel panics, the crashes did not just close the browser, but caused the entire system to require rebooting.

In a statement to Gizmodo, … Read more

Apple's MacBook Air is one of the more popular of its laptop offerings, and in its recent hardware announcements Apple updated the Air with speed and storage bumps, in addition to including the faster Intel HD 4000 graphics capabilities. While these updates have been enticing to new buyers, a number of people who have been using the new systems are experiencing crashes.

After using the systems for a while, many users are noticing that they seem to randomly crash with a kernel panic, which fades the display and presents a message that states the user needs to press the … Read more

Ordinary folks may not notice much right away from the fact that Google's Android programmers are bringing their work back into the Linux kernel fold.

But it's an entirely different situation for a smaller but important group: the programmers who like to experiment with Google's open-source mobile operating system.

So predicts Tim Bird, the Sony programmer who's centrally involved in the merge of Google's Android Linux work with the "mainline" Linux kernel project. That cooperation took a big step Sunday when Linux leader Linus Torvalds released version 3.3 of the heart of … Read more

A number of events happen when you boot your Mac that activate the hardware and load the system software. Understanding these and some of the behaviors that the system might show when problems occur during these steps can help determine what you should do if your system will not boot properly.

Powering up Upon pressing the power button on your system, computer components such as hard drives, add-in cards, and other controllers receive power and start initialization routines to ensure that their hardware is working OK. If these components are all in working order, then they will assume a "… Read more

An issue that has been plaguing some owners of MacBook Pro systems is a black-screen bug where systems will suddenly show a black and unresponsive display after performing specific tasks that may be as simple as moving a window, resizing screen elements, or when waking the system from sleep. The problem may show a kernel panic, but generally just displays the black screen and requires users to press the power button to restart the systems.

This issue was first widely noted when OS X 10.7 was released, but it soon became clear that the problem was present (albeit less … Read more

If you launch the Activity Monitor utility on your Mac, you will be able to see what processes are running and what system resources they are using. As expected, some processes will take up more RAM and CPU time than others. Seeing this in Activity Monitor can be handy for figuring out which tasks are taking up an unexpected amount of CPU or RAM. One regular culprit for using a lot of RAM is Safari, but in addition you will see another process called "kernel_task" that also will regularly use a few hundred megabytes of real RAM and … Read more
