Sometimes a new technology comes along that\u2019s so promising, so revolutionary, that, over time, future citizens consider the innovation to be commonplace. Take sliced bread for example.<\/p>\n

Sliced bread, you may be surprised to hear, wasn\u2019t baked into the fabric of everyday life until 1928, when a man named Otto Rohwedder leveraged his device through a nearly bankrupt banker. His invention, almost snuffed out of existence thanks to an unfortunate fire in 1917<\/a>, went on to make life easier for people everywhere. Loaves no longer needed cutting, knives didn\u2019t need to be sharpened and fingers were shielded from the blade.<\/p>\n

The Internet of Things (IoT)<\/a> is a lot like sliced bread: it\u2019s simple in its revolutionary nature and promises to make life easier\u2014by optimizing home temperatures, updating your traffic maps and keeping track of exercise, among other things\u2014for everyone. But IoT has a flaw: like the fire that threatened the future of sliced bread, hackers threaten to reduce IoT to ashes by abusing device connections.<\/p>\n

How can they do this? Well, there are five distinct ways hackers can compromise IoT devices. Let\u2019s take a look:<\/p>\n

1.\u00a0Data Breaches<\/strong><\/h2>\n

2014 was not kind to personal data. Repeated breaches throughout multiple industries have shaken consumer confidence in retailer and credit card security. The IoT, which collects a treasure trove of data on consumers, from spending habits and activity levels to television history and eating habits, could be worse. When not properly secured, IoT devices threaten to expose sensitive information to hackers and other cybercriminals willing to use that information to further their illegal exploits.<\/p>\n

2.\u00a0Cross-Device Access<\/strong><\/h2>\n

IoT devices connect to a smartphone, a computer or directly to a Wi-Fi network. This introduces an additional path hackers can take to access sensitive devices like your desktop computer or smartphone. By installing a malicious program\u2014often referred to as malware<\/a>\u2014on an IoT device, hackers can monitor your network and communications, spread malware to additional devices and conduct what\u2019s known as a man-in-the-middle attack<\/a>\u2014where an entity either intercepts, eavesdrops or modifies a message sent between two people or two devices.<\/p>\n

3.\u00a0Spying on Your Whereabouts<\/strong><\/h2>\n

Many IoT devices and services tout their tracking abilities. Tracking features can help plot out running paths, commute routes and measure distances. They can also tell hackers when you\u2019re away from home. By monitoring your whereabouts through Internet-connected security cameras, wearables and even thermostats, hackers may have the ability to know precisely when you are and aren\u2019t home<\/a>\u2014provided they have access to your network.<\/p>\n

4.\u00a0Botnets<\/strong><\/h2>\n

One of the biggest threats to IoT devices are botnets<\/a>\u2014networks of computers working together to achieve a goal, often illegally. IoT devices lack sufficient security and encryption technologies, making them particularly vulnerable to hackers seeking to grow their army of computers. We\u2019ve already seen this happen. Last year, we reported on an IoT botnet that employed smart TVs and refrigerators (among other devices) to send out spam<\/a>. Unfortunately, the IoT threatens to drastically increase the number of computers hackers can use to grow their botnets, if not properly secured.<\/p>\n

5.<\/strong>\u00a0Ransomware<\/strong><\/h2>\n

One of the most troubling trends in Internet security is about to get more troubling. Ransomware<\/a>, a type of malware used to hold computers and devices hostage until a victim pays a fee, will make its way to IoT devices<\/a>\u2014and it could be dangerous. Internet-connected cars, drones and other items could be taken hostage and remotely disabled in life-threatening situations.<\/p>\n

Over the next few years, we\u2019ll see a massive boom in IoT devices. But security may not boom<\/a> with it. Thankfully, there are a few things you can do to protect yourself during this turbulent transition into the future. Here are a few tips:<\/p>\n
