What is R4IoT?
How can I protect my business against it?
Ransomware for IoT (R4IoT) is a new threat that has emerged over the past few years. A type of malware that targets internet-connected devices, such as smart home appliances and wearables. They provide particular attention to operational technology (OT) settings and critical infrastructure industries.
Are your perimeter security cameras opening a door for an attack?
Is your aircon opening up chilly access to your business?
The most common way that ransomware affects Internet of Things (IoT) devices is by encrypting files. The ransomware then demands a ransom to be paid before the encryption is removed.
How does R4IoT work?
R4IoT works by infecting an organisation's network using a combination of bots and internet-connected devices (including TVs and smart speakers). The bots scan the network for vulnerable devices and send instructions to download malicious software. The malicious software then locks down the device, preventing access to files or data until the user pays a ransom fee to decrypt them.
How can organisations protect themselves against R4IoT?
Organisations can prevent an attack on their network by implementing appropriate security measures such as firewalls, antivirus software and encryption. These can be installed on both the internet-facing side (the "edge") as well as on internal networks (the "core").
More steps to protecting your business from ransomware for IoT include;
- Implement an effective backup strategy and an incident response plan in case your business becomes infected with ransomware.
- Ensure that all of your devices are up-to-date. This includes not just computers but also smartphones and tablets.
- Ensure your employees know the dangers of ransomware and what to look out for. Educate them on how to spot suspicious emails or websites so they can avoid falling victim to a scammer's ploy.
- Consider investing in an antivirus program that includes ransomware protection for IoT devices. While this might seem overkill for something like a smart lightbulb or thermostat, it will help safeguard against more sophisticated attacks on essential items such as medical equipment or other mission-critical systems.
