Cyber crime is a common occurrence in today’s interconnected world, especially when it comes to businesses. It’s not hard to see why: corporations are increasingly relying on technology to run crucial aspects of their businesses and safeguard personal and financial information.

This interconnectivity brings risk. According to ISACA’s 2017 State of Cybersecurity, 53% of enterprises experienced more cyberattacks this year than the year prior, with attacks affecting both small businesses and corporate giants.

The Equifax data breach, touted by some as the worst security breach in recent history, put 145.5 million Americans—as well as 700,000 British consumers and 8,000 Canadians—at risk of identity theft; in October, it was revealed that 3 billion accounts were affected by a Yahoo data breach that took place in 2013. Below, we’ve compiled a list of the worst data breaches of 2017.

These breaches show no signs of slowing down. Cybercrime is one of the fastest growing threats globally, and cyber crime damages are slated to cost the world $6 trillion annually by 2021.

Data breaches don’t just affect corporations and their users. According to IBM’s 2017 X-Force Threat Intelligence Index, common attacks that target individuals are also on the rise, with the volume of spam emails (the top delivery mechanism for most malware) increasing 4x in 2016.

The increasing sophistication of hackers makes it more important than ever to protect yourself and your data against threats. Develop a security strategy to keep your data safe, including creating unique passwords, using good online habits and being mindful of what data you share and who you share it with.
