The Different Types of Data Breaches Explained

Cybercriminals can access data with a variety of tools. They may try to brute force their way through your passwords or use malware to gain access to your computers, networks and devices. If you aren’t able to have your very own Business IT Support, then consider learning enough so your data is safe.

Human error is also a common cause of a breach. For example, a careless employee left a prototype of the new iPhone lying around, and within hours, it was available online for anyone to view.

Intentional Attacks

If you are curious about what is a data breach, it is an incident where sensitive or confidential information is accessed unauthorizedly. This information can be anything from personal health records, social security numbers or driver’s license numbers to corporate data like customer lists, manufacturing processes and source code software. Data breaches occur in companies of all sizes and can result from cyber attacks or internal threats.

Some data breaches are intentional and are a common target for hackers seeking to steal your private information or financial details. 

Malware is a popular tool for criminals looking to steal your data and compromise your device. It works by installing itself on your computer or network, then stealing and transmitting your digital activity to hackers who can use it for malicious purposes. This could include accessing your emails or location and sending your private information to strangers.

Hackers can crack passwords by trying every possible combination, often without detection. They may also install spyware to monitor your activities and steal or erase data from your servers. This can be devastating for companies, risking their reputation and financial stability. Consulting with security experts, such as those at frsecure.com, can help you establish robust security measures and respond effectively to cyber attacks.

In addition to these threats, issues can arise when tokenization has failed. Tokenization is a critical security process that replaces sensitive card information with a unique identifier, or token. This method enhances security by ensuring that actual card data is not exposed during transactions. However, failures in the tokenization process can lead to increased risks of data breaches and fraud. This highlights the importance of robust security measures to address potential tokenization failures and maintain secure transactions.

By understanding these various threats and implementing comprehensive security strategies, businesses can better protect their sensitive data and ensure safe, reliable operations.

Denial-of-Service Attacks

Cybercriminals often use data breaches to steal personal information that can be used to commit identity theft and other types of fraud. Those affected by these attacks can lose their bank accounts, be locked out of social media accounts, have their credit rating destroyed, and much more. For example, the Yahoo hack allowed attackers to access 1.5 billion user accounts and get their email addresses, names, unencrypted security questions and answers, and other sensitive information.

Data breaches often result from human error or a gap in an organization’s security posture. This can include negligence, carelessness or a failure to follow industry or government compliance mandates.

Examples include:

• Need to secure a website with SSL/TLS encryption.
• Leaving a database online without password restrictions.
• Accidentally sharing a document with the wrong person.

These mistakes are more common than you might think; even well-known companies fall prey to them. 

In addition to leaking information to the general public, some criminals will sell this information in dark web marketplaces. This can include stolen credit card details, business intellectual property, SSNs, and other confidential data. Other crimes that can occur due to a breach are:

• Point-of-sale data theft.
• Credential stuffing (when login credentials are exposed).
• Phishing.

Malicious Insiders

Data breaches can be caused by malicious insiders and employees who steal confidential information for financial gain or revenge. These hackers can cause a lot of damage to a company, causing lost productivity, fines and lawsuits, and reputation.

Insider threats include disgruntled employees or former workers who retain credentials to sensitive systems. They may be motivated by financial gains, a desire to get revenge on their employers or a need for recognition. They are often employed as engineers, programmers, scientists or salespeople. They may also be members of a corporate espionage team, stealing trade secrets to give third parties a competitive edge. These types of insider threats typically occur two months before an employee leaves or after resigning from their current position.

When a malicious insider threatens an organization, they must first scope out their target by searching for security weaknesses in the network and identifying which users can access unauthorized assets. They may also scan the company for hardware that can be used to infiltrate the network.  During this reconnaissance phase, an attacker might attempt to escalate their privileges without authorization or use unauthorized storage media to obtain files from the computer. These activities indicate that an attacker is trying to hide their actions from IT staff and conceal their attacks. You need to be prepared for these events and choose an LMS that meets important security factors to ensure your data is safe and secure.

Human Error

Humans are prone to making mistakes that can cost their company hundreds of thousands, if not millions, of dollars. In a typical case, someone will leave a file in the wrong place or click the “forgot password” link on their computer to let hackers inside their system. Before you know it, personally identifiable information, proprietary data or even embarrassing emails are being shared over the Internet.

Human error can also lead to a breach due to flaws in the physical security of businesses, schools and public spaces. For example, if a security guard doesn’t look out for a bomb in a building or doesn’t have enough staff to deal with a disaster, that can easily result in an intentional or unintentional breach.

In many cases, malicious attacks take time and planning to be successful. Hackers often survey where vulnerabilities lie, such as outdated software or employees’ susceptibility to phishing. They may then develop a campaign to exploit these weak points or directly attack the network. For instance, if a group of vigilante justice trolls decides they don’t like how a pharmaceutical business takes advantage of patients, they might launch a denial-of-service attack against it to compel the company to shut down.
