Tracking Hacking: The World’s Biggest Data Breaches

This data visualization comes to us from Information is Beautiful. Go to their site to see the highly-recommended interactive format that visualizes the same data, while providing additional details on each specific hack.

The graphic above shows a timeline of some of the biggest data breaches on record. Each bubble represents the number of records lost in any given breach, with the most sensitive data clustered toward the right side.

Before 2009, the majority of data breaches were the fault of human errors like misplaced hard drives and stolen laptops, or the efforts of “inside men” looking to make a profit by selling data to the highest bidder. Since then, the volume of malicious hacking (shown in purple) has exploded relative to other forms of data loss.

From Millions to Billions

Increasingly sophisticated hacking has altered the scale of data loss by orders of magnitude. For example, an “inside job” breach at data broker Court Ventures was once one of the world’s largest single losses of records at 200 million.

However, it was eclipsed in size shortly thereafter by malicious hacks at Yahoo in 2013 and 2014 that compromised over 1.5 billion records, and now larger hacks are increasingly becoming the norm.

Small But Powerful

The problems caused by hacks, leaks and other data breaches are not just ones of scale. For example, the accidental 2016 leak of information from spam/email marketing service River City Media stands out at an alarming 1.37 billion records lost. However, sorting by data sensitivity paints a different picture. The River City leak – represented by the larger blue dot below – is surpassed in severity by hacks at Yahoo, at web design platform Weebly, and even at adult video provider Brazzers.

Data Breaches Ranked by Severity

Much of the data lost in the River City hack was made up of long lists of consumer email addresses to be used for spam email distribution, while the other hacks listed compromised items like account passwords, banking information, addresses, phone numbers, or health records. While having your email address become the target for spam exploitation is a serious annoyance, the hacking of much more sensitive personal data has quickly become the norm.

The fact that more and more of our data is being stored “in the cloud” and among devices on the Internet of Things means that increasingly sensitive types of data are now more vulnerable than ever to being hacked. This looks to be even more cause for concern than the rapidly rising volume of records that have been exposed, whether intentionally or by accident.



Ranked: The Top Startup Cities Around the World

Here are the global startup ecosystem rankings, highlighting the scale and maturity of major tech hubs worldwide.

A richly connected network of founders, venture capital firms, and tech talent are some of the key ingredients driving a startup ecosystem.

As engines of growth, these tech clusters are evolving on a global scale. While the world’s leading startup cities are concentrated in America, several ecosystems, such as Beijing and Seoul, are growing in prominence as countries focus on technological advancement to spur innovation.

This graphic shows the best startup cities worldwide, based on data from Pitchbook.

The Global Startup Ecosystem Rankings

To determine the rankings, each city was analyzed based on the scale and maturity of their startup ecosystem over a six-year period ending in the second quarter of 2023.

Among the inputs analyzed and used to calculate the overall development score were fundraising activity, venture capital deals, and exit value:

San Francisco dominates the pack, with $427.6 billion in capital raised over the six-year period.

Despite a challenging funding environment, nearly 20,000 deals closed, highlighting its outsized role in launching tech startups. Both OpenAI and rival Anthropic are headquartered in the city, thanks to its broad pool of tech talent and venture capital firms. Overall, 11,812 startups were based in the San Francisco Bay Area in 2023, equal to about 20% of startups in America.

Falling next in line is New York City, which raised $179.9 billion over the same time period. Crypto firm Gemini and machine learning company, Hugging Face, are two examples of startups based in the city.

As the top-ranking hub outside of America, Beijing is home to TikTok’s parent company, ByteDance, which is one of the most valuable private companies in the world.

In recent years, much of the startup funding in China is being driven by government-backed funds. In particular, these funds are focusing heavily on “hard tech” such as semiconductor-makers and electric vehicle companies that align with the government’s strategic long-term goals.

Another leading tech hub, Singapore, has the highest venture capital funding per capita worldwide. In 2023, this was equal to an impressive $1,060 in venture funding per person. By comparison, venture funding was $345 per person in the U.S., the second-highest globally.
