Types of Data Breaches to Watch For: Security Alert!

Key Takeaways

A data breach occurs when sensitive, protected, or confidential data is accessed, stolen, or disclosed without authorization. There are several ways data breaches can occur. These incidents might be the result of malicious attacks, human error, or physical theft of information.

A data breach means the exploitation of privacy and exposure of sensitive data.

A company should protect its confidential information with every means.

Even with all security measures in the organization, a data breach is still a genuine threat to data security.

There are various types of data breaches and that possess a higher amount of risk to the sensitive data. The organization must take pre-data breaching measures and ready for the post-data breaching steps.

Most Common Types of Data Breaches

Data breaches come in various forms, each with unique risks and implications.

Below are some of the most common types of data breaches:

1. Hacking and IT Incidents

Hacking breaches are the most well-known type of data breach.

These occur when cybercriminals use sophisticated techniques to gain unauthorized access to data stored in a network or computer system.

Hackers may exploit software vulnerabilities, phishing emails, or brute-force attacks to break into an organization’s systems.

Common Methods:

• • Phishing: Cybercriminals impersonate legitimate organizations to trick employees into revealing login credentials. Clicking on phishing links will share your information with them.

• • Malware: Malicious software can be introduced into a system to steal or corrupt data.

• • Ransomware: Cybercriminals encrypt data and demand a ransom for its release.

These attacks can result in the theft of a wide range of sensitive information, including financial records, personal identities, and intellectual property.

2. Insider Threats

An insider threat occurs when an individual within the organization, such as an employee or contractor, intentionally or unintentionally accesses or leaks sensitive data.

Insider threats can be difficult to detect, especially when the person involved has legitimate access to the data.

Examples:

• • Employees who download sensitive data onto personal devices without authorization.

• • Disgruntled employees who steal company data to harm the organization.

• • Employees who make accidental mistakes, such as sending confidential files to the wrong recipient.

3. Lost or Stolen Devices

Another common type of data breach occurs when devices containing sensitive information are lost or stolen.

This could include laptops, smartphones, external hard drives, or USB drives.

If these devices are not properly encrypted or secured, any data stored on them can be exposed.

Prevention Measures:

• • Always encrypt devices containing sensitive information.

• • Enable remote wipe capabilities on mobile devices.

• • Ensure lost or stolen devices are reported immediately.

4. Physical Breaches

Physical breaches occur when unauthorized individuals gain access to physical records or systems.

These breaches might involve someone breaking into a facility or stealing physical records containing personal or confidential data.

These incidents are less common in the digital age but still pose significant risks, especially for industries dealing with large volumes of physical records.

Examples:

• • Someone stealing paper records from a hospital or bank.

• • Unauthorized individuals accessing an office and copying data from unsecured computers.

5. Data Disposal Issues

Improper data disposal is another form of data breach.

When data is not securely destroyed or erased before disposal, it may be recovered and used maliciously.

Businesses often use hard drives, storage devices, and paper documents to store sensitive data, but when these materials are not properly discarded, the information can be exposed.

Examples:

• • Selling old computers or printers without properly wiping the hard drive.

• • Throwing out sensitive documents without shredding them first.

6. Social Engineering Attacks

Social engineering breaches occur when attackers manipulate individuals into revealing confidential information or performing actions that compromise security.

These attacks are often based on psychological manipulation, where the attacker creates a sense of urgency or trust to exploit the victim.

Common Tactics:

• • Phishing emails and phone calls asking for login credentials or financial information.

• • Pretexting, where attackers pose as someone trustworthy to gain access to personal information.

7. Third-Party Data Breaches

A third-party breach occurs when a company’s data is compromised due to vulnerabilities in a third-party service provider.

Many organizations rely on third-party vendors for services such as cloud storage, payment processing, or IT support.

A breach in one of these providers can lead to the exposure of sensitive information.

Examples: A cloud service provider suffers a breach that exposes client data.

A payment gateway company experiences a breach, exposing credit card information.

8. Password Guessing:

It is also another most simple type of threat that can cause data breaches and damage your security.

This happens when you set up a very common password that anyone can guess like your birth year, birth date, or your name with some numbers.

Hackers think differently and can crack these kinds of passwords easily.

To protect your data, avoid using easy passwords, use some pattern combinations in it and secure data from hacker attacks.

9. Recording Keystrokes:

Nowadays there are some software and web applications available that can record your keystrokes on the keyboard, this software is called keyloggers.

When you enter your credentials for logging into your account, it will record your keys, hence they note your password and can access your data.

Except password-sensitive information can also be leaked.

They can then use these things for an illegal purpose or for blackmailing, as have access to your sensitive information now.

10. Malware or Virus:

Whenever hackers want to wipe out the data from the systems of organization, he tries to inject malware or virus in their system.

This can be troublesome for those companies who rely on the data.

Consider the computer virus had sent to a school’s database that wiped out the student’s information. This can cause a problem for the school administration.

Organizations can prevent these threats by avoiding spam messages and insecure links. Thus database security is quite vital.

11. Distributed Denial of Service (DDoS):

Luckily, small ventures are almost free from this threat.

Distributed Denial of Service targets the larger companies.

The reason for attacking the larger companies is the need for coordination for this attack.

It is a kind of protest that the people can do against the company.

Suppose there is a cosmetic manufacturing company, and some people dislike the way the company is running.

They can start a denial-of-service attack that will make it impossible for them to access their systems and databases.

Third-Party and Supply Chain Breaches

Understanding the Risk

Third-party and supply chain breaches occur when a vendor, contractor, or service provider is compromised, and their access to your systems or data leads to a breach.

These breaches are particularly dangerous because they exploit trust relationships and external connections that are often outside the immediate control of the organization.

How These Breaches Occur?

These breaches typically occur when a third-party vendor has direct or indirect access to your network or data. For example:

• A contractor with access to your company’s internal systems could unintentionally expose sensitive information by falling victim to a phishing attack.
• An external IT service provider might not follow proper security protocols, allowing hackers to infiltrate their systems and access client data.

Consequences of Third-Party Breaches

Third-party breaches can have devastating effects, including:

• Loss of client trust.
• Legal and regulatory consequences.
• Financial losses due to the theft or misuse of sensitive data.

How to Mitigate Third-Party Risks?

To prevent third-party and supply chain breaches:

• Conduct thorough due diligence before working with vendors or partners.
• Regularly audit third-party access and permissions to ensure that they are following your security protocols.
• Ensure that all third-party vendors are compliant with industry standards for data protection and security.

Preventing Data Breaches

To protect against the various types of data breaches, organizations and individuals must adopt robust security practices.

Some effective strategies include:

1. Strong Password Management

Using complex, unique passwords for different accounts and systems is one of the simplest yet most effective ways to prevent unauthorized access. Password managers can help store and generate secure passwords.

2. Encryption

Encrypting sensitive data, both at rest and in transit, ensures that even if data is intercepted, it cannot be read without the decryption key.

3. Regular Security Audits

Performing regular security audits allows organizations to identify vulnerabilities before they can be exploited.

This includes patching software, securing endpoints, and evaluating access control.

4. Employee Training

Employees should be trained on how to recognize phishing attacks and how to follow best practices for data security.

Ensuring that everyone within an organization is aware of the risks is crucial for preventing breaches.

5. Monitoring and Response Plans

Organizations should implement continuous monitoring to detect unusual activity.

In addition, they should have a data breach response plan in place to quickly address and contain any incidents that occur.
