Top data breach statistics 

The Identity Theft Resource Center (ITRC) defines a data breach as “when unauthorized individuals access and/or remove personal information from the place where it is stored.” Basically, it’s when any type of data is accessed by someone who is not meant to access it, often for malicious purposes. 

Recent data breaches have shown us how threat actors are getting more creative with how they access information. They’re using tried-and-true methods of access, like malware and phishing, with AI tools to make their jobs easier. Below are key cybersecurity statistics that show the state of data breaches in 2025. 

1. Data breaches, or unauthorized access to data, are among the top concerns of IT professionals in remote work environments. (Huntress)

2. Data breaches often span multiple environments, with 40% involving data stored across various platforms. (IBM)

3. 2023 was a record-breaking year for reported data compromises, with 3,205. 2024 was similar, with 3,158. However, the number of victim notices went up exponentially, by 211%, with 1.3 billion notices going out in 2024. (ITRC)

4. This means that approximately six victim notices went out for every adult in the United States. (ITRC)

5. But if you were to exclude the top five mega-breaches of 2024, there was actually a 47% decrease in the number of victim notices sent out. (ITRC)

6. The Ticketmaster attack, which threat actors claim compromised 560 million individuals, was the largest data breach of 2024. (ITRC)

Impact and cost of a data breach

Data breaches have both short- and long-term effects. Downtime and lost data can have massive financial impacts on the organization. For the end user, that lost data isn’t just a major inconvenience and invasion of privacy, but can also be a financial blow and even lead to stolen identities.

That’s not something that just goes away, either. Any negative impact on your credit score generally lasts at least seven years. And while we mostly talk about the financial impact of data breaches and other cyberattacks, there’s no doubt an implied emotional component is there, too.

7. The average cost of a data breach in the United States from 2006 to 2024 was nearly $9.5 million. (Statista)

8. Data recovery (81%), data breaches (80%), and ransomware (63%) are among the most commonly covered types of cyber events in insurance policies. (Huntress)

9. For 27% of organizations, cyberattacks cost between $100,001–$500,000 per year. (Huntress)

10. Data breaches cost an average of $4.9 million globally in 2024, which marked a 10% increase from the previous year. (IBM)

Data breach frequency and common causes

How common are data breaches? They’re happening more and more, so let’s start there.

While human error is one of the most common causes of data breaches, the threat landscape is also changing fast. Even if the average person were better about following cybersecurity best practices to reduce their attack surface, the way threats are developing would have them constantly playing catch-up.

More than that, though, threat actors are persistent. Here are some common causes of data breaches. 

20. Poor password management or using common passwords is a big concern for both in-person and remote teams, with 28% of IT professionals saying they think it’s the worst habit of remote and hybrid employees. That’s ahead of things like opening obvious phishing scams and not using a secure network. (Huntress)

21. About 9% of IT professionals feel that their organization’s data loss prevention measures are underfunded or underresourced. (Huntress)

22. It’s estimated that nearly all data breaches (95%) can be blamed on human error, such as poor cyber hygiene and falling for phishing attacks. (Mimecast)

59. Three-quarters of ransomware attacks in government are state, local, tribal, or territorial (SLTT). (Verizon)

Types of data most commonly compromised 

Data breaches frequently expose personally identifiable information (PII), like names, addresses, Social Security numbers, and dates of birth, which are highly sought after for identity theft. Beyond individual information, corporate intellectual property and sensitive internal documents are often compromised, leading to major business disruption and competitive disadvantages.

Here’s an overview of the most commonly compromised types of data:

60. 1 in 3 data breaches involve shadow data, or data created without an organization's knowledge, such as an employee saving work emails to their personal account or creating copies of sensitive information. This data goes unaccounted for by IT teams when there’s a breach, because they don’t know it exists. (IBM)

61. 84% of compromised data in 2024 was classified as sensitive data, like financial or medical information. (ITRC)

62. Passkeys are the key to prevention, particularly in breaches that involve stolen credentials. Some believe that the majority of stolen credential breaches in 2024 could’ve been avoided if organizations had made passkeys mandatory. (ITRC)

63. More than 2.8 billion passwords were posted on criminal forums in 2024. (Verizon)

64. Emails were compromised in 61% of data breaches in 2025. (Verizon)

65. Phone numbers were compromised in 39% of data breaches in 2025. (Verizon)

66. Passwords were compromised in 28% of data breaches in 2025. (Verizon)

73. Credential abuse was the initial access vector in 22% of non-error, non-misuse breaches, where human errors weren’t the main cause, in 2025. Credential abuse as an access vector can be linked to an increased use of zero-day exploits targeting VPNs and edge devices. (Verizon)

74. Exploitation of vulnerabilities was the initial access vector in 20% of non-error, non-misuse breaches in 2025. (Verizon)

75. Phishing was the initial access vector in 16% of non-error, non-misuse breaches in 2025. (Verizon)

Data breach trends

While there are consistencies year-over-year when it comes to data breaches like the human aspect of breaches and financial motivations, things also change. A major trend in 2025 is the rise in breaches involving cloud environments and shadow data. Below is an overview of some of the data breach trends this year. 

76. More than 3 of 4 remote access incidents involved remote access trojans (RATs) in 2024. (Huntress)

77. Almost a quarter (24%) of IT professionals rate cloud security breaches as one of the emerging threats they’re most concerned about. (Huntress) 

78. Infostealers were responsible for nearly a quarter (24%) of threats in 2024. (Huntress)

79. Financial gain (27%) and data theft (23%) are considered the most common motivations for threat actors. (Huntress)

80. Ransomware was present in 44% of all data breaches in 2025, up from 32% in 2024. (Verizon)

81. Ransomware impacts smaller organizations more than larger ones. It was used in 39% of data breaches on large organizations but only 88% of breaches on non-enterprise businesses. (Verizon)

Data breach response statistics

Data breach response matters almost as much as prevention. Here’s an overview of some stats that show how long reporting takes and how managed security support can improve data breach outcomes.

82. On average, it takes organizations 4.1 months to report a data breach after ransomware attacks. (Comparitech)

83. The average savings for those who use automated detection and response is $2.2 million. (IBM)

84. Organizations within designated industries, such as finance and government sectors, are required to report data breaches and other cyber incidents to Homeland Security within 72 hours. (CISA)

How to protect against data breaches

Proactive measures are important in preventing data breaches. Here are our tips for protecting your personal and organizational data from data breaches and other cyberattacks. 

• Perform regular updates and audits: Evaluate cybersecurity measures at regular intervals to make sure there are no potential vulnerabilities and all systems are compliant. 

• Invest in EDR: EDR solutions give you continuous monitoring and analysis of endpoint activities for rapid detection, investigation, and automated response to sophisticated cyber threats that traditional antivirus solutions might miss. This visibility and quick containment minimize the impact of attacks, reduce response times, and help maintain business continuity.

• Train employees: Human error is a major factor in data breaches. Conduct regular security awareness training for all employees, focusing on spotting phishing attempts, recognizing social engineering tactics, secure data handling practices, and reporting suspicious activity.

• Use passkeys: Passkeys shift the security burden away from easily compromised human memory and vulnerable server-side password storage, placing it firmly on secure, device-based authentication. This reduces the impact and likelihood of breaches stemming from stolen or phished credentials.

• Implement least privilege: Adhere to the principle of least privilege, where individuals only have access to the data and systems absolutely necessary for their role. Regularly review and revoke access as roles change or employees leave.

• Have an incident response plan: In the event of a data breach, it’s important to have an incident response plan already in place. This includes steps for assessing damage, locking down and backing up accounts, and reporting through the proper channels, such as to the Internal Crime Complaint Center.
