101+ Data Breach Statistics – The Big Scary Online
Updated · Apr 06, 2022
On March 18, 1990, two men in police uniforms entered an art museum in Boston. They performed the largest fine art theft in the history. 13 paintings of world famous artists were stolen that day.
To this day, their frames remain empty on the walls of the museum.
Now, 1990 also saw the dawn of another kind of robbery. Storing data on the internet is one of the greatest technological advancements and we have all enjoyed it immensely.
It came at a price though…
Since the advent of the global network, robberies have become much more subtle, as these comprehensive data breach statistics curated by Hosting Tribunal can tell you.
The modern ways of stealing are harder to track and can affect a lot more people.
Let’s look at some quick data breach facts first.

Responsible and Irresponsible Companies in the Times of Data Breaches
Data breaches alone are nasty enough. They can become even more dangerous if companies fail to inform their users and decide to keep the information for themselves.
Time is a key factor after a cyber attack has occurred. Every time a personal user account is breached, the user must be informed immediately.
As we will see in a moment, though, that almost never happens…
Here is a list that will shed some light on the response times for various data breaches:
Companies which Informed Their Customers Swiftly
- Sony – After the Sony PlayStation data breach, the company took less than a week to inform its customers about the attack.
- Target – The company did an amazing job with the detection of the data breach. It took them 16 days to detect and 20 days to inform the customers.
- Facebook – Super professional in how quickly they informed the public. Not that professional, considering the breach happened because they had been storing hundreds of thousands of user IDs and passwords in plain text for years before the incident.
Companies that Took Forever to Inform Customers
- Yahoo! – With the pending sale to Verizon, the company decided to remain quiet and keep its sale price.
- Uber – The company informed the public almost 1 year after the incident of 2016.
- Marriott – It took 2 months to inform customers their accounts have been attacked.
So, here we are, guys.
Now we have seen the ugly face of Cyber Attack Cerberus, and what he is capable of.
And he seems to know what he’s doing out there, terrorizing the village…
After all, if we just google how many data breaches took place in just 2018, we’ll come up with the mindblowing number of 945. Cerberus isn’t for the faint of heart.
Still, data breach statistics do have some good news to tell us. Namely, those companies are having more and more success in stopping those attacks. Their incentive is two-fold – they appreciate having their customers’ trust… as well as paying less money in case settlements.
Whatever the reason for this progress – we, the users, will take it.
