Another week, another attack vector, and this one deserves extra points for creativity.
New research has proved the viability of using something as simple and innocuous as sound waves to disrupt the normal functioning of HDDs, which can be used to sabotage a wide range of equipment from Pcs, to CCTV systems, ATMs and more.
Researchers have toyed with, and been aware of the possibility of using sound waves to disrupt the normal functioning of an HDD for more than a decade, but the most recent research conducted by scientists from Princeton and Purdue universities have outlined exactly how such an attack could be carried out.
The attack exploits a peculiar design feature of HDDs. Because they store large amounts of data on small platters, they’re designed to shut down in the presence of excessive vibration to avoid scratching or damaging the platter, and thus, destroying information on the drive.
If a hacker can determine the optimal attack frequency against a given HDD, then he could play a sound aimed at the drive that would cause it to stop functioning. If the sound were played long enough, it would require the system to be manually restarted to get it working again.
As the researchers demonstrated, finding the optimal attack frequency is a trivial enough task, but it should be noted that this is a fairly exotic type of attack, and not likely to see widespread use.
The biggest threat one would potentially face from such an attack would be the disruption of the functioning of security cameras to create a blind spot at a facility, which could then be physically breached. But given that the tones are within the range of human hearing, anyone in the vicinity could come and investigate.
Nonetheless, it’s an intriguing bit of research with potentially damaging implications.
AMD long ago dropped support of 32-bit operating systems, and now, Nvidia is following suit. The long-anticipated move by the company will mean the end of driver support for the 32-bit builds of Windows 7, Windows 8, Windows 8.1, Windows 10, Linux and FreeBSD.
“Paint” is one step closer to being a thing of the past.
Chromebooks have brought Android apps to a much wider market, making them accessible to virtually everyone, but the Chrome OS has always lagged behind other platforms developmentally.
One of the greatest challenges among small business owners today is making the decision about IT support and maintenance of the information system; whether to hire an in-house IT tech or to outsource IT support for their business. With the relatively recent availability of Managed Services for small business, the list of choices – and decisions – has grown once again.
Facebook scams are fairly common occurrences, owing to the sheer size of the platform’s user base. It’s no surprise that there’s a new one making the rounds that you should be aware of.
There’s some bad news if you own a computer driven by an Intel processor. Recently, a dangerous, catastrophic security flaw has been discovered in Intel’s X86-64 architecture that allows hackers to access the kernel, which sits at the heart of your OS. By accessing the kernel, a hacker can gain access to virtually everything on the targeted machine.
Not long ago, observant Reddit users noted and began discussing a curious phenomenon. It appeared that older iPhones were unexpectedly slowing down, and no one could name the reason why.
Few things are more ubiquitous in an office environment than printers. Of course, these days, most printers are much more than simply that. They can also scan, copy and even send emails. As such, they’ve become an increasingly attractive option to hack, according to the latest data released by Barracuda Networks.
