In just 10 cyber incidents last year, over $600 million in cash was stolen or taken as ransom, tens of millions of citizen records stolen, 40,000 businesses’ IT operations put at risk, one billion airline passenger details compromised and at least one bank was effectively shut down for over a week, according to Tokio Marine HCC International’s (TMHCCI) second annual Cyber Incidents Report.

The vast majority of the incidents listed in this year’s top 10 involved large institutions where cybersecurity plays an integral role in operations, but this did not prevent their sophisticated defense systems from coming under attack, confirmed the report, titled “Top 10 Cyber Incidents 2021.”

Indeed, some of the most damaging attacks were experienced by the likes of Microsoft, Kaseya and SITA, organizations whose products and services feed directly into the systems of third parties.

“We are noticing a drastic increase in both likelihood and severity of all types of cyber attack. We have seen a marked increase in ransomware attacks, their complexity and in the appetite to target smaller organizations,” said Isaac Guasch, cybersecurity specialist at TMHCCI and author of the report.

“But whether you are a small independent business or a large international organization, the increasingly interconnected nature of the businesses that form our economies is a key threat,” he added.

“Even if you are confident that your cybersecurity measures are up to date, those of your partners may not be, so you may need to constantly redefine your perimeter.”

Ranking the top 10 global cyber incidents by impact shows that targets of attacks operate in a range of business sectors including IT, airport security, banking, energy, software component providers and government databases, said TMHCCI in its analysis of the data.

“It’s clear that organizations of all shapes and sizes need to understand that wherever they are and whatever they are engaged in, their business is at risk,” said Xavier Marguinaud, head of Cyber at TMHCCI.

“But by gathering, analyzing and understanding the nature of these incidents, TMHCCI is able to better understand threat trends, attacker motivation and modus operandi. This insight allows us to provide effective insurance solutions that include tailored pre- and post-incident services to ensure your organization is best prepared for any cyber threats,” Marguinaud continued.

The report named the top 10 cyber incidents in 2021 as:
