The Internet of Things (IoT) is amazing, but it’s not perfect and, in particular, there are plenty of security vulnerabilities that you need to know about.

You can barely move without bumping into an IoT device now and, whilst this allows you to be more productive, it also means that the security risk to your organization’s network is increasing. We’ve all heard about how coffee machines can get hacked and it’s these types of stories that demonstrate the extent of IoT security concerns.

Whilst you may rely on a humble kettle rather than a fancy Wi-Fi controlled coffee machine, there are still plenty of IoT security vulnerabilities you need to be aware of. Let’s take a look at of the most important ones you should be aware of.

  1. Network Services Present a Back Door

IoT devices often come with diagnostic and debugging services built in to help facilitate troubleshooting tasks, but these are often operating on ports which are not secure. Now, maintenance services are probably one of the least likely to be secured pieces of code to be found on an IoT device, so this scenario is highly attractive to hackers. Therefore, you need to make sure that you investigate all potential security concerns on new IoT devices you install.

  1. Lack of Transport Encryption

When data is transported across the internet or your local network, it needs to be encrypted to thwart any external parties who are listening to your data traffic. However, many IoT devices fail to employ transport encryption in their data transmissions when sending data – this is estimated to be around 41% of all IoT devices. And this is why you need to make sure that your organization only works with highly secure IoT devices to protect data security.

  1. Weak Password Protection

The lack of strong password protection is a major security vulnerability when it comes to IoT devices. A good password should incorporate more than 8 characters and these should include numbers, symbols and mixed case letters – more often than not, though, these can often be nothing more than four digits such as an iPhone’s default password protection. And, as we all know, the weaker a password, the quicker and easier it can be hacked by brute force.

  1. Different Computer Languages Prevent Security

PCs all speak a common language, so getting a network full of PCs to operate on the same network in the same manner is not too big a problem. However, a smart photocopier running on a code all of its own is going to struggle to communicate effectively with the rest of your network. And this means that guaranteeing a secure connection between network devices is more difficult than ever. You also need to consider the fact that many IoT devices fail to receive regular updates, so this has the potential to be a long term security risk.

We’re all still learning about the security vulnerabilities that the IoT is bringing to the security table, so a firm knowledge of the potential pitfalls is vital. By taking note of the above you should be able to improve your security just enough to prevent being hacked.

Feb 2018

If you want to keep the IoT (Internet of Things) secure in 2018 then you’re going to have your work cut out due to the number of threats on the horizon.

Significant progress has been made in the last couple of years when it comes to understanding the security concerns presented by IoT devices, but this is only encouraging hackers to become more innovative. And 2018 is going to deliver more IoT security threats than ever before, so you’re going to need to be ready for this surge in activity and the new hacking methods employed.

Let’s take a look at the most pressing IoT security concerns coming in 2018.

  1. IoT Attacks Being Undetectable

Many IoT attacks take place on a micro scale compared to large scale attacks such as Distributed Denial of Service Attacks. The problem with micro attacks is that conventional security systems are unlikely to recognize them as a threat, whereas major attacks are likely to ring alarm bells very quickly. Therefore, investing in highly sensitive security systems and manual monitoring may become vital to any organization using IoT devices.

  1. Automation Will Become More Important

Some organizations can have thousands of IoT devices operating on their network at any one time, so manually monitoring this activity is virtually impossible. And that’s why automation and artificial intelligence could prove highly popular in 2018 when it comes to providing a front line defence against IoT attacks e.g. installing crucial firmware upgrades immediately.

  1. The Irresistible Allure of Cryptocurrency

You only have to take a quick look at the financial headlines to understand just how valuable cryptocurrencies are at the moment. And, to a hacker, the financial rewards on offer are hard to resist. The Satori botnet, for example, takes control of IoT devices and also allows the hackers to exploit Bitcoin mining software. So, if your organization is involved with cryptocurrencies in any capacity, it’s going to pay to monitor your activity very closely.

  1. More and More Devices Will Be Targeted

Automobiles, security cameras and baby monitors are just a small selection of the IoT devices which have been hacked in the last couple of years, but this is set to increase further in 2018. In particular, devices which come with weak passwords (or even no password) are constantly being scouted by hackers. And, when they discover one, this can easily be leaked online, so the need to enforce a strong password culture remains essential.

  1. Privacy Concerns

Trusting IoT devices to transmit and receive personal and sensitive data is going to come under serious scrutiny in 2018. Due to the recent IoT attacks which have exploited weak passwords and poor security protocols in IoT devices, the public concern is growing over how their data is handled. Naturally, hackers are excited by the prospect of being given a free run at such a huge number of vulnerable devices without adequate security frameworks in place. 2018, therefore, is going to find organizations having to soothe customer concerns by only working with secure hardware and software.

With Internet of Things (IoT) devices becoming more prolific at work, their security risks are increasing. In particular, botnets are posing a major threat.

Botnets have been associated with hacking since the start of the 21st century and don’t show any signs of disappearing soon. Therefore, it’s no surprise that hackers are adopting these services into their attacks on IoT devices. The aim of a botnet is to create a huge network of infected computers connected to the internet to carry out DDoS attacks, spam campaigns and steal data. And, with the proliferation of unsecured IoT devices now online, it’s not hard to see why they’re so attractive to hackers.

One botnet which has been creating a few headlines recently is Reaper, so it’s a good place to start understanding their method of operation and how you can protect yourself.

The IoT Reaper Comes to Town

IoT devices, partly due to their recent emergence, aren’t exactly the most safe and secure devices to be connecting to your organization’s network. Sure, many of them are safe, but there are so many reports of devices being released with vulnerabilities in their code, a lack of firmware updates and default password exploitation issues. Accordingly, the warnings attributed to IoT devices need to be taken seriously. And when it comes to botnets such as Reaper, you can begin to understand why.

The Mirai botnet was the first big hack which took advantage of shortfalls in IoT security and its legacy is Reaper. Evolving the operation and build of Mirai (Reaper even shares some code with it), Reaper is a more sophisticated piece of malware. Mirai’s approach was to act purely as a password cracker, but Reaper is taking nine different approaches to exploit known vulnerabilities in devices manufactured by Linksys, GoAhead and NetGear to name but a few.

Reaper has the potential to create a huge botnet army and, with its myriad infection methods, could carry this out with much more ease than Mirai ever managed. Security researchers Checkpoint even estimate that around one million networks have been scanned in order to begin recruiting vulnerable devices. Reaper is also built to ensure that it can receive regular updates through new script updates and indicates a potential for the malware to be regularly strengthened.

Thankfully, the number of recruited bots has remained relatively low compared to initial estimates with around 10,000 to 20,000 drones being active at any one time. Experts suspect this may be down to poor coding, but with the potential for new updates to be patched into the malware, this could be rectified very quickly. A further benefit to consumers is that the hardware providers being targerted are tight on security and regularly issue firmware updates.

Keeping the Reaper at Bay

Allowing automatic firmware updates – and regularly checking manufacturers’ websites/social media for security updates – is paramount to keeping your organization’s IoT devices secure. Not only can botnets launch global attacks on computer networks, but they can also slow down individual devices and render them redundant.

Default Passwords: The Biggest Weakness in IoT Security

Passwords have always been one of the simplest security methods, but the presence of default passwords in the IoT (Internet of Things) is very dangerous.

Many IoT devices come set up with a default password in place which is certainly a nice option, but when that default password is the same across the entire product range then it presents a major security flaw. Say, for example, you buy an IoT fish tank (yes, these actually exist) and it shares the same default password as all other IoT fish tanks in that product range, it’s not going to take much research to discover that password, is it? Sure, it’s just as easy to change the password, but how many people would think about adjusting security settings on a fish tank?

As more and more organizations are installing IoT devices, it’s a good idea to familiarize yourself with the dangers of default passwords and how to make your passwords more secure.

Default Passwords and their Dangers

It’s estimated that 15% of IoT device owners fail to change their default password, so it’s almost certain that all medium and large businesses have at least one employee with a susceptible IoT device. It’s partly laziness on the owners’ parts and it’s partly down to IoT technology being so new that people aren’t aware of the security risks. Nonetheless, it’s presenting a major security issue for organizations as hackers are taking full advantage of the situation.

Hackers are concentrating on the construction of malware which comes preloaded with huge lists of default passwords, so that breaking through defenses becomes that little bit easier and quicker. And this is exactly what happened when the Mirai botnet managed to infect nearly 185,000 IoT devices by exploiting default passwords. Default passwords are regularly being leaked and shared online, so the importance of changing these as soon as possible should be a paramount concern for organizations.

Protecting Against Default Passwords

If you want to improve the security on your IoT devices and protect the rest of your organization’s network, then you need to take note of the following tips:

  • Change the Password on a Protected Network: Before your IoT device is connected to the internet, make sure that it’s connected to an exclusive, protected network that cannot be accessed externally. This allows you to, first, test the device and, secondly, to change the password before it’s detected by IoT search engines such as Shodan. 
  • Run Regular Audits on All IoT Devices: Detecting and monitoring new devices on your network should become a priority. Any new and unknown devices to your network should instantly be blocked and an authentication process put in place. With this information you can then track down the device owner and ensure that any default passwords are changed before further access to the network is granted.
  • Don’t Use Admin as a Username: Admin is probably the most common username used in IT departments and hackers are well aware of this. Even if you’ve changed your default password to something highly cryptic, a simple username such as ‘admin’ instantly halves the amount of work a hacker has to do.
