Legacy Stripe API Exploited in Web Skimmer Campaign to Validate Stolen Payment Cards
TL;DR
Cybersecurity experts have identified a sophisticated web skimmer campaign leveraging an outdated Stripe API to validate stolen payment information. This tactic enhances the efficiency of the operation by ensuring only valid card data is exfiltrated.
Introduction
Cybersecurity researchers have uncovered a sophisticated web skimmer campaign that exploits an outdated Stripe API to validate stolen payment information before exfiltration. This tactic ensures that only valid card data is sent to the attackers, making the operation more efficient and potentially harder to detect.
Key Findings
- Exploitation of Legacy API: The campaign utilizes a legacy Stripe API to validate stolen payment card information.
- Enhanced Efficiency: By validating card data before exfiltration, the attackers ensure that only valid information is sent, making the operation more efficient.
- Detection Challenges: This method can make the operation harder to detect due to the reduced volume of invalid data being transmitted.
Details of the Campaign
Threat hunters have warned of a sophisticated web skimmer campaign that leverages a legacy application programming interface (API) from payment processor Stripe to validate stolen payment information prior to exfiltration. This tactic ensures that only valid card data is sent to the attackers, making the operation more efficient and potentially harder to detect” Jscrambler researchers Pedro.
Implications and Recommendations
This campaign highlights the importance of securing legacy APIs and maintaining robust cybersecurity measures. Organizations should:
- Regularly update and secure all APIs.
- Implement advanced threat detection mechanisms.
- Conduct regular security audits to identify and mitigate vulnerabilities.
Conclusion
The exploitation of the legacy Stripe API in this web skimmer campaign underscores the ongoing threat posed by cybercriminals. Organizations must remain vigilant and proactive in their cybersecurity efforts to protect against such sophisticated attacks.
