Hackers have been compromising wireless baby-monitors since 2013, but the more popular they've become, the more vulnerable they've become, and the attacks just keep getting more terrible.
Shodan is a search engine for the Internet of Things, scanning the public Internet for devices communicating on ports and over protocols that are commonly used by IoT devices. By feeding it the right parameters -- Real Time Streaming Protocol (RTSP, port 554) -- you can find innumerable publicly shared webcams, ranging from CCTVs that oversee marijuana grow-ops and many, many baby-monitors.
"The consumers are saying 'we're not supposed to know anything about this stuff [cybersecurity]," he said. "The vendors don't want to lift a finger to help users because it costs them money."
If consumers were making an informed decision and that informed decision affected no one but themselves, perhaps we could let the matter rest. But neither of those conditions are true. Most consumers fail to appreciate the consequences of purchasing insecure IoT devices. Worse, such a quantity of insecure devices makes the Internet less secure for everyone. What botnet will use vulnerable webcams to launch DDoS attacks? What malware will use insecure webcams to infect smart homes? When 2008-era malware like Conficker.B affects police body cams in 2015, it threatens not just the reliability of recorded police activity but also serves as a transmission vector to attack other devices.
"The bigger picture here is not just personal privacy, but the security of IoT devices," security researcher Scott Erven told Ars Technica UK. "As we expand that connectivity, when we get into systems that affect public safety and human life—medical devices, the automotive space, critical infrastructure—the consequences of failure are higher than something as shocking as a Shodan webcam peering into the baby's crib."
Internet of Things security is so bad, there’s a search engine for sleeping kids

It’s free for anyone to take, and Finns can get credit at the Open University of University of Helsinki (yes, that’s what it’s called).
The Dirty Cow vulnerability dates back to code included in the Linux kernel in 2007, and it can be trivially weaponized into an easy-to-run exploit that allows user-space programs to execute as root, meaning that attackers can take over the entire device by getting their targets to run apps without administrator privileges.
A China-based maker of surveillance cameras said Monday it will recall some products sold in the United States after a massive “Internet of Things” malware attack took down a major DNS provider in a massive DDOS attack. The stunningly broad attack brought much internet activity to a halt last Friday.
TV antennas are making a comeback, and the Ghost Indoor HDTV antenna is a great example of why. Unlike the old bunny ear-style antennas, this compact antenna is barely noticeable and picks up channels easily. Plus with the addition of streaming services like Netflix, we find ourselves with plenty to watch without a pricey monthly cable bill. The Ghost […]
I’ve never really felt the need to purchase a smartwatch because a lot of them aren’t very functional, but at just shy of $30, the Martian Notifier Smartwatch was worth checking out. For that low of a price, it actually does feature an impressive amount of functionality, and comes in handy when you don’t want to be carrying around your […]
