Artificial Intelligence

Industry-changing technological advancements occur in waves. Mobile, the cloud, big data, IoT – are all examples of major technological advancement waves. The latest wave is Artificial Intelligence (AI). Quantum and nano waves are yet to fully arrive. While the technology of previous waves is still very relevant, often it is the latest flavour-of-the-month which commands front-page attention.

Wi-Fi routers – the internet’s next Archilles heel

IoT heralds a quantum leap in the number of devices connected through a Wi-Fi router. In the home for example, devices such as lights, electric plugs, cameras, alarms, kettles, refrigerators, etc. communicate with each other on the local Wi-Fi network, and to the internet through the home router/modem. If one device on the Wi-Fi network is compromised, the attack could compromise the router itself, as well as data from other devices on the network. An example is a recent vulnerability discovered in a connected kettle which is able to steal router passwords.

Evil maid and the short-comings of full-disk encryption

Stefan Esser is an iOS security researcher based in Cologne, Germany. Last month when returning to his Frankfurt hotel room after dinner one evening, he noticed that his laptop had been tampered with in his absence. On investigation he concluded that the hard drive had been removed and then improperly replaced. It appears Stefan may have become victim of an Evil Maid attack. A bit of a give-away indication was the hotel room door handle which also appeared to have been the target of tampering.

Of Volkswagens and malware sandboxing

So everyone knows about the VW emissions scandal. Software in the car’s engine management system can detect when an emission test is being carried out (a give-away clue is when the vehicle is on a dynamometer), and reduce engine performance in order to provide better emissions test results. Malware developers use a similar technique to evade file-based sandbox detection methods.

The ascension of man over fridge

Comments I’ve seen indicate that many are concerned about the advent of IoT. Specifically, misgivings are about the security and privacy of data. Historically, the information technology sector has not had a good track record with security and privacy, and people are worried that more connected devices will only exacerbate the situation.

Dridex elicits same old tired advice

This week saw a resurgence of the Dridex malware. There is little novel or outstanding about the malware – it infects PCs through a Microsoft Office document which victims are encouraged to open in order to trigger a malicious macro. Once installed, the malware harvests data when the victim conducts online banking. Normal stuff. Reports say £20 million has been stolen.

The future shape of IoT

ThingBook5

Three core components make up the IoT ecosystem: Things, People and Events. A simple example is a smart thermostat (Thing), operated by the home owner (People), which activates home heating when the temperature drops below a certain point (Event). IoT is essentially about the interaction and relationships between, and within, these three core components.
