According to Dimension Data’s Executive’s Guide to the NTT Security 2017 Global Threat Intelligence Report, the number of denial-of-service (DoS) or distributed-denial-of-service (DDoS) cyber attacks doubled from 3% to 6% in 2016, due to a lack of security controls around Internet-connected Internet of Things (IoT) devices.
The report also indicated that of all IoT attacks, 60% originated from Asia, 21% from EMEA and another 19% from the Americas. The most likely reason for the high volume of attacks from Asia is that technology sourced from the region has historically been susceptible, and compromised infrastructure tends to be reused to perpetrate additional nefarious activities.
The report was compiled from data collected by NTT Security and other NTT operating companies including Dimension Data, from the networks of 10,000 clients across five continents, 3.5 trillion security logs, 6.2 billion attempted attacks, and global ¹honeypots and ² sandboxes located in over 100 different countries.
Global honeypot sensors monitored IoT cyberattacks and their targets over a six-month period. Based on the credentials used by threat actors, it was determined that 66% of attacks targeted specific IoT devices such as a particular model of video camera. These attacks appeared to be from compromised IoT devices attempting to find and compromise even more such devices. This would be consistent with an attacker acquiring a large number of devices to use in DDoS and other forms of attack. Of the balance of 34% of the analysed attacks, it’s likely these were also attempting to grow the attacker’s arsenal by targeting other types of devices.
DDoS attacks using IoT devices can impact an organisation in multiple ways. They can:
– Prevent customers, partners, and other stakeholders from accessing their organisations’ Internet-facing resources, thereby impacting sales and other daily operations;
– Prevent employees and internal systems from accessing the Internet, disrupting many facets of operations; and
– Affect organisations providing services from the Internet, which can cause supply chains to be broken.
“There’s nothing about a DDoS attack which requires use of IoT devices only, so attackers may look for as many devices as possible regardless of type,” explained Mark Thomas, Dimension Data’s Cybersecurity strategist. He points out that while DDoS attacks are the most recognised threat, they’re not the only potential outcome of an organisation’s IoT and ²operational technology (OT) devices being compromised.”
There are a number of actions that organisations can take to protect their businesses including:
· Make security a primary consideration for all Internet of Things and operational technology
device purchases;
device purchases;
· Authorise funding as needed to replace older Internet of Things and operations technology
devise purchases;
devise purchases;
· Conduct threat and vulnerability assessments; and
· Ensure devices are discovered and profiled within an organisation.
According to a February 2017 press release by research firm, Gartner Inc, 8.4 billion connected things will be in use worldwide in 2017- up 31% on 2016. This number will reach 20.4 billion by 2020. And total spend on endpoints and services will reach almost $2 trillion in 2017.*
Jay Reddy, Solutions Executive for Dimension Data Middle East and Africa, “The number of ways that IoT devices can help people and organisations is boundless. However, there’s also much evidence that the expansion of the Internet enabled through mobility, cloud adoption, and the proliferation of the Internet of Things, has exposed new attack surfaces. Vulnerabilities are rife, data is exponentially increasing, privacy is being eroded, and the cost of breaches is becoming debilitating.”
