A data leak occurs when sensitive information is exposed outside of its intended environment. It may be the result of malicious intent or simple internal human error like misconfiguration of software, lost/stolen endpoints, and poor security protocols. This can compromise personal details, financial records, and trade secrets. Data leaks and breaches lead to expensive regulatory fines, litigation costs, and loss of customer trust.
The most common causes of a data leak are human error and technical misconfigurations, which are often preventable with strong password protection, regular software updates, and staff training on best practices. Malicious actors use phishing, malware attacks, and credential compromise to gain access to systems, where they can then exploit weaknesses in the security infrastructure.
Malicious insiders can also cause a data leak, whether it is intentional for financial gain or retribution, or simply because they want to take the information with them when they leave for another job. Leaked data can also include intellectual property, which cybercriminals can use to commit fraud and other crimes.
The cost of a data leak can be severe, especially for a small business, impacting the ability to attract customers, investors, and employees. Reputational damage can also be devastating, and it can be difficult to recover from. However, it is possible to minimize the damage from a data leak by promptly and transparently informing existing parties that their information has been compromised. This helps maintain the integrity of the organization, reassures them that you are taking steps to prevent future incidents, and allows individuals to protect themselves from harm.
