Taking a step back from digital crime, the simple act of listening to two people talk in the real world using microphones and recorders can often lead to the gain of personal information. Phones can be hacked into by remotely activating the device's speaker function.
The same can be done to laptops, where microphones are switched on discretely to listen in on the owner. As there are hackers looking to eavesdrop on every person's digital conversations, there are also cyber security experts working non-stop to ensure online conversations are kept as secure as possible. There are a number of ways this is done, including:. A large part of the duties of a cyber security expert is to encrypt data before it is transferred using digital networks.
Encryption basically refers to scrambling the data before sending it to the receiver so that any third party that tries to read the data only sees a string of gibberish. The receiver, on the other hand, has an encryption key which can be used to unscramble the message and retrieve the information in a safe and secure manner.
Another important duty for cyber security experts is to build digital networks for their companies that are capable of withstanding attacks from hackers and are immune to attempts at digital eavesdropping. A host of firewalls and anti-virus software are used by security experts to make sure all the information that travels between the network's nodal points does not lie exposed before hackers who may have accessed a particular port. Far too many people who use the internet know nothing about keeping data secure, or believe in using outdated methods of protection that have long since been made obsolete by new and improved hacking methods.
Working for a company as a cyber security expert means you will often be called upon to explain the basics of cyber security to other employees who use the company's digital network. You will have to teach them to pick a strong password, to keep changing the password at regular intervals, not to download or open unknown files off the internet and other security basics which will help protect the company's network.

For instance, computer users have, from time to time, reported speaking words in online conversations that subsequently seem to trigger pop-up advertisements on certain web pages and social media networks, though these claims are usually denied. It has not always been clear to what extent some legitimate apps, like Microsoft's Cortana, gather information about what you're saying, leading to genuine privacy concerns.
And, on the other side of the law, hackers have demonstrated how they can trick their way into computers and smartphones to switch on microphones without users being aware. A couple of years ago, computer security firm Panda identified spyware that could switch on a phone's mic, identify where the device was located, record conversations and track the user all day. This sort of eavesdropping goes hand-in-hand with illegal or questionable remote accessing of web cameras, which we reported on in an earlier issue, Webcam Safety Threatened by Crooks and Spies.
There's no better evidence that the risk of this spying is real than the recent publication of a photo of Facebook founder Mark Zuckerberg, whose laptop, in the background of the photo, was seen to have tape placed over both the camera and mic. You can usually tell if your camera is in use because most of them have a tiny light next to the lens that switches on with the camera.
But with a microphone, there's generally no visible signal. It's also reportedly possible in some circumstances for headphones and even speakers to be used to collect conversation, even when a microphone is turned off or disconnected. It's all this uncertainty over whether, how and why speech is being eavesdropped that creates user concern. While we can't guarantee to make you soundproof, there are a number of key actions you can take to minimize the risk of being overheard or recorded, or of your microphone being activated without your knowledge.
Then, disable the mic when you don't need it.
