A botnet is a network of systems, combined with the purpose of taking control remotely and distributing malware. and phishing emails.With the rise of the Internet of Things (IoT) many objects and devices are under threat, or are already becoming part of the so-called CheeseBot – a botnet that incorporates independent connected objects.There are many different devices in the botnet as well as cheesebots, which are connected to each other

– from computers, laptops, smartphones and tablets to now “smart” devices.

These things have two main features: they are Internet enabled and they are able to transfer data automatically through a network. Anti-spam technology can very reliably spot if a machine sends thousands of similar emails, but it is very difficult to spot if those emails are being sent from different devices that are part of a botnet.

They all have a goal: If thousands of email requests hit a target, it doesn’t come as a big surprise if the platform crashes while struggling to cope with massive amounts of requests.Botnet took a major risk, for example attacks against critical infrastructure or gaining unwanted access to company networks. It grows without the knowledge of the device owner.

Day-to-day items such as printers, fridges,

or televisions often do not receive the same level of protection as smartphones or laptops, so they provide easy access for hackers who can use their next chance to launch an attack. Are looking for A well-known example was the attack on the Xbox and PlayStation networks last Christmas, where home Wi-Fi routers were used to mount the attack. Microsoft and Sony could not withstand the amount of server traffic through the DDoS (Distributed Denial of Service) attack, which stopped online services.

Many devices are meant to track your habits, such as what time you are at home and want to use heating, or a connected camera to protect against physical intruders. This is not only interesting information for your comfort and safety, but is also desirable for criminals. You need to keep in mind that the information that you can get through the Internet can also be viewed by hackers if it is not properly protected. And with IoT development still in its infancy, weak security is often still the case.

Different levels of protection

Why is it that we already use a high level of security for computers, or online banking, but ignore it when it comes to similarly protectable devices such as smart heating systems? We are used to two-factor authentication for online banking, happily combining password / username combinations with randomly generated security codes or similar. This is often not yet implemented for smart devices.

From Botnet to Thingboat

Whereas in the past the Windows operating system was primarily targeted as part of the botnet, now Apple and Android devices increasingly attract the attention of cybercriminals. but that’s not all. With the rapid development of the Internet of Things, those tools are already proving to be a popular target.

Worldwide it is believed that more than 500 million computers compromise every year. With 50 billion connected devices by 2020, it’s not hard to imagine that hackers are looking for cheesebat-heaven.

Securing IoT with Traditional PKI Deployment

Internet enabled devices are a huge threat, as they can be easily targeted. Most users have neither the possibility nor the knowledge to protect devices. Also a large number of devices allow areas for mass attack.

PKI is based on tried and tested decades-old standards, which provide sufficient flexibility to adapt to the changing requirements of IoT. It provides authentication, encryption and data integrity and thus ticks the three major security boxes

Encryption:

Looking at the types of devices coming for online privacy is a major concern. It is necessary to encrypt communication to and from devices. PKI-based solutions provide some basic and necessary encryption mechanisms to ensure the confidentiality of communications.
