At least 4,000 IoT devices, and probably more were bricked thanks to a new strain of malware called Silex and the 14-year-old hacker who unleashed it. Silex was first discovered by Akamai senior intelligence response engineer Larry Cashdollar. It’s similar to 2017’s Brickerbot in that it targets insecure IoT devices, specifically ones that run a Linux or Unix OS and have known or easily guessable default passwords. Silex uses the insecure logins to destroy the device’s storage and remove their network configuration, effectively turning them into paperweights.Cashdollar told Threatpost that he was contacted by the hacker via Twitter and was told that the goal was to remove vulnerable IoT devices to prevent other hackers from using them to create botnets. At some point however, the command and control center server vanished.

Google announced that together with Amazon and Apple (the big 3 smart home players) they will work on the adoption of a joint wireless IoT standard for the smart home. This new connectivity standard is designed to make it easier for smart home products to work with each other.In the statement, Google said they were “joining Amazon, Apple and others to create Connected Home over IP, a new independent working group managed by the Zigbee Alliance (separate from the existing Zigbee 3.0/Pro protocol). We’re contributing two of our market-tested and open-source smart home technologies, Weave and Thread. Both are built on IP and have been integrated into millions of homes around the world.”

Four ways to ensure IoT success

Article | February 12, 2020

Three out of four IoT projects are considered a failure, according to Cisco. This is troubling but even more so when Cisco also found 61 per cent of companies say they believe they’ve barely begun to scratch the surface of IoT can do for their business? Businesses believe in the long-term value offered by integrating IoT into their business plan, however, they lack the knowledge of what is required to ensure the success of such a complex project. By studying past failed projects, technology leaders can gain a better understanding of why they failed and what they can do differently when evaluating and undertaking new IoT initiatives.

IoT as a Service: Lowering the Cost Barrier of IoT for Small and Mid-Sized Businesses

Article | February 12, 2020

There are already 20 billion IoT-connected devices, and 8 billion of those are devices used by enterprises, according to a report by Gartner. The impact of the Internet of Things market is potentially $11 trillion by 2025. The investment in IoT has come primarily from large businesses, but the technology is increasingly available via ‘as-a-service’, making it possible for businesses of all sizes to benefit. The ‘as-a-service’ model reduces the cost of ownership and capital expenditures and makes it easy for small businesses to investigate IoT with smaller up-font investments and less risk. Frank Della Rosa, research director at IDC, said that “Software as a Service (SaaS) continues to be the most highly deployed cloud segment, representing a commanding 62.4% of the total cloud market revenues.”

IoT developers to focus more on smart healthcare post-COVID-19

Article | February 12, 2020

Healthcare technologies will be a greater priority among IoT service providers once the disruptions caused by the COVID-19 die down, according to Forrester Research. Based on its latest figures, only 7% of the work that major IoT service providers deliver in APAC is on Smart Healthcare. The crisis has triggered a lot of ideas and solutions, however there was simply no time to look at a more strategic approach for both the technologies and the processes. This will be the focus of governments, health care providers, and others, once the acute crisis is behind us,” said Achim Granzen, principal analyst at Forrester, told FutureIoT. He added: “I expect this number to increase past Covid-19, as governments, healthcare providers, and others will seek to harden many of the ad-hoc systems and measures they have put into place during the crisis.”
