WITH  cyber attacks increasingly targeting critical infrastructure such as healthcare and power grids, the global threat landscape has moved beyond mere data theft to pose direct risks to human lives, a senior cybersecurity expert has said. Gaurav Shukla, Partner and Leader - Cyber at Deloitte South Asia, noted that the convergence of Information Technology (IT) and Operational Technology (OT) has expanded the attack surface, making sectors like aviation, transport, and public utilities highly vulnerable. For the past two years, we observed that cyber threats were not limited only to the IT systems. They were pervading beyond

 

IT systems, and the perpetrators were targeting more of the critical infrastructure. A lot of digital transformation, which has taken place in the last few years or so, has expanded the attack surface, and whenever the attack surface increases, it provides more opportunities for the attackers to come and cause disruption. “If you are driving a connected car on a highway at 120 km/h and suddenly find the steering is no longer in your control, you are not going to be worried about how much money is in your bank account.

 

You are worried about the danger to your life,” Shukla said, highlighting that cybersecurity boundaries are now shifting from data security to human safety. Shukla explained that a cyber attack on a medical device altering patient data could be fatal, while a hack on power generation and transmission components could cause severe national blackouts. Highlighting the surge of connected devices, Shukla pointed out that the global population of eight billion is currently surrounded by over 30 billion IoT (Internet of Things) sensors, meaning an average human is surrounded by more than 3.5 sensors at any given time.
