The number of devices connected to the internet is expected to reach 50 billion worldwide by the end of 20301, posing dangerous risks to people, businesses, and critical systems. To illustrate the divide between cyberattacks on these devices and business preparedness, Sectigo, a leading provider of automated digital identity management and web security solutions, today released its Evolution of IoT Attacks study.
The study report and associated infographic chronicles the progression, variety, and growing sophistication of many of the most infamous vulnerabilities and attacks on connected devices, as well as the emerging defences used by organisations to fight them.
Sectigo has categorised IoT attacks into three eras:
The Era of Exploration
Beginning in 2005, cybercriminals started to explore the potential to cause lasting damage to critical infrastructure, and even life. Security defences at the time were rudimentary, with organisations unaware of the value the IoT could have for hostile actors.
The Era of Exploitation
Spanning 2011-2018, cybercriminals actively exploited the lucrative and damaging potential of attacking the IoT, thus expanding attacks to more targets with increased severity. However, they found organisations more prepared to withstand the onslaught. White hat hackers exposed potential IoT vulnerabilities to help shore up defences before attacks occurred in the wild. Meanwhile, as organisations fortified their defenses, cybercriminals found more ways to monetise their attacks through crypto-mining, ad-click fraud, ransomware, and spam email campaigns.
The Era of Protection
By 2019, enterprises and other organisations had become increasingly capable of countering these attacks. Just recently, governments have begun enacting regulations to protect IoT assets, and businesses and manufacturers are heeding the warnings. In fact, according to the recent 451 Research Enterprise IoT Budgets and Outlook report2, organisations are investing more than half of their IoT budgets, 51%, to implement security controls in devices, using security frameworks and unified solutions with strong technologies that work together to provide multiple layers of protection.
“As we move into this decade, protecting the vast Internet of Things has never been more critical for our safety and business continuity,” said Alan Grau, VP of IoT/Embedded Solutions at Sectigo. “Cybercriminals are retooling and honing their techniques to keep striking at vulnerable targets. Yes, businesses and governments are making laudable efforts to protect all things connected, but we are only at the beginning of the Era of Protection and should assume that these efforts will be met by hackers doubling down on their efforts.”
IoT security must start on the factory floor with manufacturers and continue throughout the device’s lifecycle. Power grids, highways, data security, and more depend on organisations adopting ever- evolving, cutting-edge security technologies in order to withstand attacks.
