A very strange (and worrying) new form of computer virus appears to be able to infect your PC through its speakers.
The rootkit virus is apparently able to communicate with other computers using your speaker and microphone.
Named "badBIOS", the virus has apparently been around for years - but exactly how it works has only just been revealed.
An in-depth report on Ars Technica quotes researcher Dragos Ruiu who said that the virus appears to be able to jump through the air to other machines - even when they were not connected to the internet, or each other.
The theory is that the software is using inaudible high-frequency sounds to send data to other machines, e
The report admits that the virus is "the stuff of urban legend" but says that the evidence appears to prove that it exists.
That said, the evidence for the bug has mainly been collected by one researcher, and has not yet been peer reviewed, which for some reduces its credibility.
However elements of the story have been proven by multiple teams, so it appears that there's something real, and a bit terrifying, about the whole tale. It's also eerily reminiscent of the "world's most advanced virus" Flame,
discovered in 2012, which is capable of controlling a computer's speakers and microphones apparently to enable large-scale espionage.
We recommend heading over to Ars Technica to read the full story.

White Noise Generator
Worried someone around you is <a href="http://articles.businessinsider.com/2011-07-28/strategy/29998051_1_bank-employee-consent-conversation" target="_hplink">secretly recording everything you do?</a> No fear! There's a relatively low-tech way to defeat such snoops, via white-noise-producing <a href="http://www.amazon.com/Productive-Home-Security-Prducts-Jammer/dp/B002PJ7PYS" target="_hplink">audio jammers</a>. These tiny devices use white noise to blur the sound picked up by hidden microphones and other surreptitious recording devices.
Hidden cameras got you down? Blind them all with a simple baseball cap lined with infrared LEDs. <a href="http://creator.wonderhowto.com/amiehold/" target="_hplink">Amie, a hacker on WonderHowTo</a>, shows the world <a href="http://mods-n-hacks.wonderhowto.com/how-to/make-infrared-mask-hide-your-face-from-cameras-201280/#" target="_hplink">how to make one</a>, while <a href="http://translate.google.com/translate?u=http%3A%2F%2Fwww.oberwelt.de%2Fprojects%2F2008%2FFilo%2520art.htm&langpair=de%7Cen&hl=en&ie=UTF8" target="_hplink">this German art exhibition</a> lays out how these ingenious devices work.
These receivers reveal the telltale electronic crackle of hidden mics and cameras. Strangely enough, they were around long before "surveillance culture" became a <a href="http://digitalcommons.law.yale.edu/ylsspps_papers/64/" target="_hplink">common phrase</a>. Today they're sold in all sorts of <a href="http://www.gadget-playground.com/bug-detection.html" target="_hplink">shops for surveillance paranoids</a>.
Sometimes hiding your face isn't enough; sometimes you don't want to be seen at all. For those days, there's camera maps. The <a href="http://www.mediaeater.com/cameras/locations.html " target="_hplink">NYC Surveillance Camera Project</a> in the US is currently working to document the location of and working status of every security camera in New York City. <a href="http://bigbrotheriswatching.co.uk/Anpr_Camera_Locations.html" target="_blank">A similar project</a> is also in progress in the UK.

Disposable mobile phones <a href="http://www.amazon.co.uk/Pre-Pay-Mobile-Phones-Communication/s?ie=UTF8&page=1&rh=n%3A10394961" target="_blank">are more expensive than you think</a>, but they don't require personal information when you sign up.
Radio-Frequency Identification (RFID) chips are now <a href="http://electronics.howstuffworks.com/gadgets/high-tech-gadgets/rfid.htm" target="_hplink">regularly implanted</a> in passports, ID cards, credit cards and travel papers. These tiny chips make machine-reading your documents easier -- but could also let anyone with the right type of scanner <a href="http://articles.cnn.com/2006-07-10/tech/rfid_1_rfid-industry-rfid-journal-rfid-chips?_s=PM:TECH " target="_hplink">scrape your information <em>and</em> track your whereabouts</a>. Luckily, gadget geeks have come to the rescue again, this time with<a href="http://www.thinkgeek.com/product/8cdd/" target="_hplink"> RFID-blocking wallets</a>. These wallets create a Faraday cage around your items, keeping their data secure until you take them out to be scanned where they're supposed to be scanned. Destroying the chip is simpler: <a href="http://www.instructables.com/id/How-to-blockkill-RFID-chips/" target="_hplink">just nuke it in the microwave for five seconds</a>. Of course, whatever you're microwaving might <a href="http://www.youtube.com/watch?v=4_5UYcyO3Pg" target="_hplink">burst into flames</a> first...
The progress of the government's so-called 'Snooper's Charter' is currently stalled in Parliament, but using Skype may be a way to avoid officials tracking your phone calls. <a href="http://www.techweekeurope.co.uk/comment/how-to-avoid-gchq-snooping-use-skype-71410">Tech Week Europe suggests that Skype users have less cause to be worried about their data</a> being intercepted. The reasons are pretty technical, and any system is fallible, but it may be worth looking into.
