Mobile payments are exploding in popularity, with fintech apps like Apple Pay, Google Pay and CashApp enabling easy peer-to-peer transactions. But convenience often comes at the cost of security. As mobile payments gain adoption, evaluating their cyber risks and whether biometric authentication lives up to its promises becomes critical.

The Rise of Mobile Payments

Financial services delivered via mobile devices have grown exponentially, providing users new ways to bank, invest, and pay. Driving this growth is the convenience mobile payments offer over cash and cards for activities like:

– Splitting bills between friends
– Paying contractors or service providers
– Donating to charities or political campaigns
– Buying online products and services
– Transferring funds overseas

Industry surveys indicate over 90 million Americans used mobile payment apps in 2021, nearly double from two years prior. However, this rapid growth has attracted cybercriminals eager to exploit vulnerabilities.

Attack Avenues and Security Pitfalls
Mobile payments face many of the same security challenges as online banking, while introducing new risks related to devices. Potential attack vectors include:

– Malware or spyware on devices to steal login credentials and financial data.

– Phishing scams inducing users to download fake payment apps containing malware.
– Intercepting or rerouting authentic SMS messages used for account verification.
– Exploiting vulnerabilities in NFC payments like Apple Pay and Google Pay to steal money.
– Leveraging SIM swap fraud to hijack target users’ phone numbers.

– Cracking weaker PIN codes or passwords protecting payment apps.

– Harvesting biometric data like fingerprints or face scans to enable account takeover.

Additionally, data privacy is a concern with payment apps having access to spending habits, merchant relationships, and other sensitive information.While providers implement fraud monitoring and encryption, mobile introduces new surfaces of risk.

The Promise and Limitations of Biometrics
In response to growing threats, many payment apps now offer biometric logins using fingerprints or facial recognition. Biometrics addresses security pain points like cumbersome passwords and risks of SIM swapping or phishing. Fingerprints and facial scans are certainly harder for hackers to steal than credentials stored digitally.

However, biometrics has limitations:

– Once leaked, fingerprints and facial data become permanent vulnerabilities.
– Presentation attacks use spoofed fingerprints or images to fool scanners.

– Device readers can have reliability issues related to image quality.

– Legal protections against compelled biometric logins remain weak.

Implementing biometrics securely requires utilizing presentation attack detection, improving reader resilience, and combining biometrics with secondary factors like device ID, location services or user behaviors.

Best Practices for Users

Users should follow security best practices to protect mobile payment accounts:

– Avoid sideloading shady apps with malware or spyware.

– Carefully examine app permissions and data access.

– Enable multi-factor authentication using biometrics alongside passwords/PINs.

– Be skeptical of any SMS messages or in-app requests asking for sensitive data.

– Monitor financial accounts routinely for unauthorized activity.

– Report suspicious transactions immediately and deactivate affected accounts.

As mobile payments expand, fintech providers and consumers must remain vigilant against increasingly sophisticated cyber threats. Biometrics offers improved security but is not a panacea. Following cybersecurity best practices and implementing layered safeguards provides more reliable protection.

Fintech innovation continues revolutionizing how users access financial services, with mobile payment apps delivering unmatched convenience. However, these services also expose consumers to cyber risks if proper precautions aren’t taken. The industry should continue advancing biometric and behavioral profiling techniques while educating consumers on mobile payment security. With vigilance, the promise of fintech can be realized securely.
