CHAPTER 1

What Are Data Breaches?

We live in a technical society that is both exciting and terrifying at the same time. Never

before have we had instant access to information and services at the touch of a button—

from the devices we carry in our pockets, the computers on our desks, or the TVs in our

houses. While this unprecedented level of access to online services is exciting, it also

brings a lot of personal risks. To access these services, we have to give up our information

to companies that we must entrust with it. Unfortunately, although we trust these

companies with our data, we are continually hearing in the news about data accounts

being stolen.

First, let’s discuss what a data breach means. A data breach is where the sensitive or

confidential data that a company is responsible for holding has been viewed by, used by,

or stolen by a person who is unauthorized to do so. A data breach can happen for a lot of

reasons. For example, an employee at a company could deliberately or accidentally copy

or reveal information to someone who is not authorized to view it. Another example is

someone who has inadvertently left a phone, laptop, or USB memory stick on a train or

in a café. While this may be accidental as opposed to a deliberate action, it is still a data

breach. Another example, and the one that is reported in the press the most, is when

someone outside of an organization manages to infiltrate a company’s IT systems and

steal data. This could be through hacking and taking advantage of exploits in the system,

or by coercing a staff member through social engineering.

Just how prevalent are data breaches? There are some fantastic resources online

that illustrate just how much of a problem data breaches are, but I want to draw your

attention to one in particular on a website called Have I Been Pwned, by security

researcher, speaker, and trainer, Troy Hunt (see Figure1-1).

could also include sensitive information, such as credit card numbers, and health

information, such as prescriptions. This data has a lot of value to people on the black

market because it helps with identify theft. When breached data includes unencrypted

credit card numbers, it can be used to make online purchases, leaving the owner of

that data with a financial loss. These risks are very worrying, and as well as just being

inconvenient, the result of some of these data breaches can have a genuine human impact.

A prime example of this was the Ashley Madison data breach in 2015. Ashley

Madison is a dating website for people looking to have extramarital affairs. In 2015,

a hacking group called the Impact Team stole the site members’ personal data. The

Impact Group threatened to release the members’ personal information if the website

was not immediately shut down. Ashley Madison didn’t comply with this request, and

on August 18, 2015, the group leaked more than 25GB of the site members’ data onto

the Internet.

Setting aside the nature of this website, imagine if you were a site member having

extramarital affairs. How would you feel? No doubt, very nervous that your partner

would find out. Shortly after the leak of this data, many Internet sites appeared to let you

publicly search this information for someone’s name or email address. This enabled

suspicious wives, husbands, or partners to search for information. You can only imagine

the fallout from this, as many people’s relationships broke down and divorces were filed.

Many celebrities and government officials were also exposed, which had an impact on

their careers. Not only does being exposed like this affect the people involved directly,

but imagine the hurt it can also cause families and children. Sadly, there were even a few

suicides reported due to this data breach.

The reason I mention the Ashley Madison data breach is to explicitly highlight

the human consequences that a data breach can cause. I am not only talking about

stolen money from a credit card, or someone’s identity impersonated to apply for

credit, although these are very serious in their own right, I am talking about actual

consequences to people’s lives and families. No matter what your personal opinion is

about a website like this, the people that signed up for the service should expect that the

company would look after their data and assume that the data would be kept private.

In other words, it is the company’s responsibility to look after private and personally

identifiable information correctly.

Securely looking after personal data is a difficult problem to solve, and it can be an

expensive problem for companies to deal with secure storage of data. Unfortunately,

there is still an attitude with some companies that they are too small to be attacked,

Chapter 1 What are Data BreaChes?

Regulatory Impact

Penalties handed down by regulatory bodies have a direct financial impact on

organizations that suffer data breaches. For example, if you lose credit card information,

then you may have stiff fines because of violations of PCI-DSS (Payment Card Industry–

Data Security Standard) regulations. I have worked for a financial organization that

suffered a breach of customer cards, which resulted in hefty fines. These fines are

designed to be large enough to cause pain to the companies involved.

The financial services industry isn’t the only regulated industry that can hand

down penalties. The healthcare industry is monitored to protect patient data. Medical

records are very sensitive and private, and if not handled carefully, customers or patients

can suffer a lot of distress, so the fines are sized to act as a harsh punishment to the

organizations involved.

In addition to industry-specific regulatory bodies monitoring companies, each

country has government regulatory bodies to protect the consumer. In the European

Union, for example, this comes in the form of regulations, such as the General Data

Protection Regulation (GDPR). Any company that trades with an EU company has to

comply with these regulations, and the rules governing GDPR and the safe storage of

personal information are rigorous.

Loss ofReputation

All the impacts and penalties discussed so far are very serious and can cause a company

significant problems if they are experienced in the event of a data breach, but by far the

most severe impact a company can face is that of reputational damage. Trust between

a company and its customers is very hard to build, yet very easy to lose. If your business

encounters a data breach that is then exposed in the press, it is very likely that you will

lose the trust of your customers, and they will take their business elsewhere. Overnight,

this could drastically impact business revenue streams. Loss of revenue, coupled with

stiff financial penalties from regulators, can be tough to recover from. Larger companies

can bounce back, but it is a very steep uphill struggle. Smaller organizations might not

be so lucky, and the impact can force them out of business.

All of these impacts can be devastating to an organization, but you can protect

yourself from the consequences. While it might not be entirely possible to entirely

outsmart determined career criminals, if you make your security sturdy enough,
