107 Must-Know Data Breach Statistics for 2020

As more and more companies experience crippling security breaches, the wave of compromised data is on the rise. Data breach statistics show that hackers are highly motivated by money to acquire data, and that personal information is a highly valued type of data to compromise. It’s also apparent that companies are still not prepared enough for breaches even though they are becoming more commonplace.

In fact, the 2019 Data Risk Report found that companies still keep thousands of files unprotected and open for anyone inside the company to access. Let’s take a look back at some of the most impactful and damaging data breaches statistics on record and take a deep dive into the origin of data breaches.

We’ve compiled 107 data breach statistics for 2020 that also cover types of data breaches, industry-specific stats, risks, costs, as well as data breach defense and prevention resources. Hopefully, this will help organizations understand the importance of data security and how to better allocate their security budgets.

What is a Data Breach?

A data breach is any incident where confidential or sensitive information has been accessed without permission. Breaches are the result of a cyberattack where criminals gain unauthorized access to a computer system or network and steal the private, sensitive, or confidential personal and financial data of the customers or users contained within.

The U.S. Department of Justice defines a breach as “the loss of control, compromise, unauthorized disclosure, unauthorized acquisition, access for an unauthorized purpose, or other unauthorized access, to data, whether physical or electronic.”

Common cyber attacks used in data breaches are:

• Ransomware
• Malware
• Phishing
• Denial of Service

The Origin of Data Breaches

Although data breaches seem more prevalent nowadays due to cloud computing and increased digital storage, they have existed as long as companies have maintained confidential information and private records. However, publicly disclosed data breaches increased in frequency in the 1980s and awareness of data breaches grew in the early 2000s.

According to the Office of Inadequate Security website, in 1984 the global credit information corporation known as TRW (now called Experian) was hacked and 90 million records were stolen. In 1986, 16 million records were stolen from Revenue Canada.

Most public information on data breaches only dates back to 2005. In 2019, surveys showed that over half of Americans were concerned about data breaches in the healthcare industry, making data security a top concern for consumers and companies. Data breaches today tend to impact millions of consumers in just one attack on a company.

In a recent data breach literacy survey that ran in October 2019, Varonis found that 64% of Americans have never checked to see if they were affected by any major data breach. 56% said they wouldn’t know what to do if their information was involved in a data breach.

How Do Data Breaches Occur?

A data breach occurs when a cybercriminal infiltrates a data source and extracts confidential information. This can be done by accessing a computer or network to steal local files or by bypassing network security remotely. While most data breaches are attributed to hacking or malware attacks, other breach methods include insider leaks, payment card fraud, loss or theft of a physical hard drive of files and human error. The most common cyber attacks used in data breaches are outlined below.

Ransomware

Ransomware is software that gains access to and locks down access to vital data. Files and systems are locked down and a fee is demanded commonly in the form of cryptocurrency.

Common Target: Enterprise companies and businesses

Malware

Malware, commonly referred to as “malicious software,” is a term that describes any program or code that harmfully probes systems. The malware is designed to harm your computer or software and commonly masquerades as a warning against harmful software. The “warning” attempts to convince users to download varying types of software, and while it does not damage the physical hardware of systems, it can steal, encrypt or hijack computer functions.

Malware can penetrate your computer when you are navigating hacked websites, downloading infected files or opening emails from a device that lacks anti-malware security.

Common Target: Individuals and businesses

Phishing

Phishing scams are one of the most common ways hackers gain access to sensitive or confidential information. Phishing involves sending fraudulent emails that appear to be from a reputable company, with the goal of deceiving recipients into either clicking on a malicious link or downloading an infected attachment, usually to steal financial or confidential information.

Common Target: Individuals and businesses

Denial of Service (DoS)

Denial of Service is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. It is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.

Common Target: Sites or services hosted on high-profile web servers such as banks

Historical Data Breach Statistics

Some of the biggest data breaches recorded in history were from 2005 or later. Once governments and businesses moved from paper to digital, data breaches became more commonplace.

In 2005 alone there were 136 data breaches reported by the Privacy Rights Clearinghouseand more than 4,500 data breaches have been made public since then. However, it is fair to believe the actual number of data breaches is likely higher since some of the data breaches that the  Privacy Rights Clearinghouse reports on have unknown numbers of compromised records. The 2014 Verizon Data Breach Investigation alone reported on 2,100 data breaches where 700 million records were exposed.
