Online security breaches pose significant risks to both consumers and businesses, particularly in eCommerce, where financial data is often stored for convenience. Cybercriminals exploit vulnerabilities through methods such as credential theft, phishing, social engineering, and cookie stuffing to access personal and financial information. This stolen data, especially if validated, can be highly lucrative when sold on darknet markets. Businesses face challenges in protecting customer data and preventing account takeovers, especially since security partly relies on user habits. Tools like bot detection technology and fraud prevention libraries, such as Fingerprint, can help mitigate these risks by identifying and blocking unauthorized access attempts, thereby safeguarding sensitive information and maintaining consumer trust.
