All You Knew to Know About a Data Breach

What is a Data Breach?

A data breach occurs when confidential, sensitive, or protected data is accessed or disclosed without authorization, compromising the data’s confidentiality, integrity, or availability. This can affect individuals, businesses, and governments, making it crucial to implement robust cybersecurity measures to prevent data breaches.

Common Cyberattacks Used in Data Breaches


Malware is malicious software designed to infiltrate and damage your systems, often to steal information. For example, a Trojan horse disguises itself as a legitimate file to trick users into downloading it, giving attackers access to the system.


Phishing attacks start with deceptive emails that appear to come from trusted sources, coaxing recipients into revealing their login credentials on a fake login page.


Vishing involves fraudulent phone calls or voicemails claiming to be from reputable companies to trick individuals into divulging personal information, such as bank details.


Similar to phishing, smishing uses text messages to impersonate legitimate companies and solicit personal information from victims.

Brute Force Attacks:

Hackers use brute force attacks to systematically guess passwords until they find the correct one. Weak passwords and automated tools make this process faster for attackers.

Software Exploits:

Cybercriminals exploit vulnerabilities in software and systems to gain unauthorized access. These vulnerabilities can exist in operating systems, web browsers, and other applications.
