How Does a Data Breach Happen?
Data Breach is when a business or organization experiences an attack that exposes their confidential, sensitive, and protected information. It can result in severe consequences that include financial loss, damaged reputation with customers and clients, and regulatory fines from increasingly stringent data and privacy regulations like GDPR and CCPA.
How Does a Data Breach Happen?
Hackers typically use a combination of methods to breach organizations. They start by researching the target through open-source intelligence, court records, and financial filings. Then they scan systems, enumerate devices and accounts, and find vulnerabilities. They exploit these flaws by delivering malware, taking over accounts, or leveraging physical security weaknesses to enter the network. They then download their payload, which may be intellectual property, customer PII, or anything else they’re after.
Once they’re inside a system, hackers install tools to maintain access and cover their tracks. They also may wipe logs and reroute redirection mechanisms to prevent detection.
A major example was the 2024 hack against National Public Data that exposed up to 2.9 billion records with highly personal information of individuals in the U.S, Canada, and the U.K. Thieves used this information to sign up for new accounts and commit tax identity theft. People who are notified of breaches early can take steps to limit damage, such as changing passwords and monitoring accounts for fraud activity. If your company has suffered a breach, it’s important to create a response plan and know how to report the breach to authorities. You’ll want to identify the source of the breach and consult legal counsel with expertise in data security and privacy laws, such as GDPR and CCPA.
