Financial documents are records that show how a business or person handles money, such as invoices, purchase orders, bank statements, tax files, payroll records, contracts, and payment instructions. In cyber security, these files are high-value targets because they reveal cash flow, suppliers, account details, and internal processes. If exposed, they can increase fraud, legal, and commercial risk.
Attackers often steal financial documents during ransomware, phishing, or insider incidents to support extortion, invoice fraud, business email compromise, or social engineering. Defenders treat them as sensitive data by limiting access, encrypting storage, logging downloads, and separating payment workflows. Strong backups and data loss prevention help reduce the impact if attackers try to copy or leak these records.
