List of data breaches

List of data breaches is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of data breaches rather than just read about it. In short: This is a non-exhaustive list of reports about data breaches, using data compiled from various sources, including press reports, government news releases, and mainstream news articles. The list includes those involving the theft or compromise of 30,000 or more records, although many smaller breaches occur continually.

Key takeaways

List of data breaches belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect List of data breaches to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of List of data breaches from memory before moving on to harder problems.

Reference excerpt

This is a non-exhaustive list of reports about data breaches, using data compiled from various sources, including press reports, government news releases, and mainstream news articles. The list includes those involving the theft or compromise of 30,000 or more records, although many smaller breaches occur continually. Note that other sources compile more complete lists. Breaches of large organizations where the number of records is still unknown are also listed. In addition, the various methods used in the breaches are listed, with hacking being the most common. As a result of data breaches, it is estimated that in first half of 2018 alone, about 4.5 billion records were exposed. In 2019, a collection of 2.7 billion identity records, consisting of 774 million unique email addresses and 21 million unique passwords, was posted on the web for sale. In January 2024, a data breach dubbed the "mother of all breaches" was uncovered. Over 26 billion records, including some from Twitter, Adobe, Canva, LinkedIn, and Dropbox, were found in the database. No organization immediately claimed responsibility.

Worked examples

Example 1 — a first encounter with List of data breaches

Start with the simplest possible case. Write down what List of data breaches claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of data breaches before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of data breaches ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of data breaches

In research: List of data breaches appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of data breaches in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of data breaches is common in secondary-school and first-year university syllabi. It links to neighbouring topics Crime-related lists, Cyberwarfare, Data breaches, so understanding it makes those chapters shorter.
In everyday life: Look for List of data breaches outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
