The Different Types of Data Breaches: Why a data breach can happen, and how you can avoid them before they happen.

Types of data breaches

When we think of a data breach, it’s easy to picture the cliché of a mysterious hacker in a dark room typing away on his computer. The reality, however, is something a little bit more down-to-earth. In fact, simple human error is often the biggest factor. Here are some of the most common types of data breaches and how simple they tend to be:

• Phishing: This is one of the most common methods. It involves an email or message designed to trick someone into sharing a password or clicking a link.

• Malicious software: Programs such as malware or keyloggers can enter your computer, quietly recording keystrokes or removing files. Ransomware is a variant of this that locks your files until a ransom is paid.

• Simple human error: This could range from accidentally emailing a private file to the wrong person to a developer leaving an access key in code where it can be found.

• Physical theft: Sometimes the breach is as simple as a work laptop or phone being stolen from a car or office.

• System weak spots: Sometimes software contains bugs or unpatched vulnerabilities that can be exploited to gain unauthorised access. Another common risk is eavesdropping, where data transmitted over unsecured public Wi-Fi networks is intercepted.

• Insider threats: This involves a current or former team member intentionally sharing data for their own gain.

The good news? Many of these data breaches can be avoided. By recognising that a breach can range from a sophisticated program to a misplaced laptop, businesses can start taking small, proactive steps to keep everything secure.

What are the signs that you’ve been involved in a data breach?

Data exposure isn’t always obvious. While some organisations notify users quickly, in many cases, the first warning sign is a small, unusual change in your day-to-day digital activity. Staying alert to these subtle signs can help you identify and address an issue before it escalates. Watch out for the following:

• Unexpected alerts: Password reset emails or login notifications from services or accounts you don’t recognise.

• Mystery messages: Verification codes for services you don’t use.

• Strange transactions: Unknown charges on your bank statement or changes to your online profiles.

• Official word: Receiving a formal notification that your email or credentials were part of a recent incident.

If something feels off, it’s always safer to check with an Managed IT specialist like Dynamic Business Technology for your peace of mind.
