November 29, 2023

As humans become more dependent on digital technology to live, work, and play, the risk of cyberattacks has increased substantially.

According to a study conducted by Comparitech, over 71 million people are victims of cybercrime every year. Further, the number of cyberattacks has continued to increase year over year.


As a result, healthcare organizations, financial institutions, and leaders in the cybersecurity industry have begun to search for ways to minimize the risk of a successful cyberattack. The cyberattack statistics below indicate that the best time to prioritize cybersecurity awareness was roughly two years ago before cyberattacks became the fastest-growing crime in the United States.

Becoming familiar with the stats in this article can help you and your organization understand security incidents' prevalence and severity. Read on to learn about the latest information on cybersecurity spending, the average cost of a data breach, and the ways cybercriminals look to steal an organization's sensitive data.

Cryptojacking Statistics

Cryptojacking is a form of e-crime in which hackers use an individual or organization's computer system to mine cryptocurrencies like Bitcoin or Ethereum. While relatively new, cryptojacking statistics indicate an uptick in mining activities.

Criminals may initiate a cryptojacking attack in several ways, such as installing malicious software through an email attachment or infecting a webpage with JavaScript that launches the mining process when opened in a browser. Regardless of how criminals initiate a cryptojacking attack, the cyberattack consumes system resources and energy while impacting the integrity of its security processes.

Key Statistics:

  • An estimated 25% of organizations have become victims of a cryptojacking attack.

Most Common Causes of Data Breaches in Cybersecurity

With sophisticated phishing campaigns causing more than 30% of all data breach incidents worldwide, organizations have become increasingly aware of their substandard cybersecurity practices, which often contribute to the attacks.

Poor cybersecurity measures aren't the only reasons for data breaches, though. Other common causes include a lack of cybersecurity awareness training, easily accessible systems, and a lack of managed security services or adequately trained cybersecurity professionals.

Key Statistics:

  • Physical actions make up 4% of all data breaches, such as stealing paperwork or mobile devices.
  • Social engineering attacks and financial pretexting account for 22% of security breach incidents worldwide.

The Cost of Cybersecurity

Cyberattackers have begun launching more advanced – and expensive – attacks in recent years. In 2020, the average cost of successful attacks reached $133,000. While high, the number doesn't come as a surprise since the cost of web attacks has increased by 15% annually since 2016.

Experts expect the numbers to continue to grow, with estimated global cybercrime costs reaching $10.5 trillion by 2025.

Key Statistics:

  • On average, data breach incidents cost companies more than $3.9 million.
  • The average cost of cybersecurity breaches increased by an average of 27% worldwide in 2017.

Recent Cyberattacks and Breaches

In recent years, e-criminals have increased their efforts. As a result, even vanguard tech companies have seen some of the biggest cyberattacks and supply chain attacks on record, resulting in millions of exposed files, compromised user information, and an inability to continue daily operations.

Some of the most recently hacked organizations include:

  • Facebook
  • LinkedIn
  • T-Mobile
  • Robinhood
  • Twitch
  • GoDaddy
  • Android
  • First American Financial Corporation
  • Yahoo
  • Marriott International

Below, we'll look at some of the most impactful cyberattacks throughout various industries.

Federal and Local Government

In 2020, a cyberattack by a Russian-backed group led to a string of data breach incidents throughout the United States federal government. The attack resulted in the exposure of extremely high-profile, sensitive records. Upon further investigation, analysts found that the hackers may have had access to files for as long as nine months before the US government discovered the breach.


Another breach–also contributed to a Russian hacking group–occurred in March 2021. Hackers accessed the US State Department's email server and stole thousands of communications.

At the same time, reports showed local government bodies experienced an increasing number of phishing attempts in 2020 and 2021, including DDoS attacks and zero-day attacks, which occur when hackers exploit a cybersecurity vulnerability.

Small Businesses / Enterprise

According to cyberattack statistics, small businesses account for 43% of cybercrime.


Even so, less than 15% of enterprises are prepared for an attack.

Small businesses and enterprises often find themselves at the heart of cyber attacks for several reasons. First, they rarely have adequate security measures to protect their data and systems.

Secondly, cyberattacks have become increasingly frequent, with more than 66% of small businesses experiencing web attacks within 12 months. Lastly, e-criminals have launched sophisticated attacks, resulting in highly targeted attempts to breach websites, cloud-based systems, and databases.

Generally speaking, small businesses and enterprises most frequently experience phishing or social engineering attacks. However, compromised or stolen devices make up 33% of small business cyberattacks, while credential theft accounts for 30% of breaches.

Financial Institutions

Throughout 2021, the financial sector experienced a 238% increase in web attacks throughout the first few months. In addition, 75% of insurance groups and financial institutions have noticed a rise in cybercrime since the beginning of the pandemic.

Further, the US Department of Treasury's Financial Crimes Enforcement Network revealed in September 2020 that financial institutions had lost more than $1 billion in web attacks each month. In addition, more than 100 financial institutions experienced DDoS threats, while hackers turned to mobile banking apps for access to financial information, personal details, and more.

In total, the financial services sector experienced average costs of $5 million per breach. However, experts believe escalated, frequent attacks could result in higher costs or potential financial crises.

Higher Education and School Districts

Since 2005, higher education institutions have been involved in nearly 1,000 data breaches, resulting in roughly 18 million exposed records. According to experts, school districts and higher education institutes have become targets for hackers for several reasons, including large amounts of personal information, poor cybersecurity measures, and easily accessible databases.

Similarly, US school districts have experienced more than 1,000 cyberattacks since 2016. In 2020 alone, 53 school districts became the victim of an attack, costing more than $7.5 billion to the education sector.
