The Crucial Need for Mobile Security in Retail Point of Sale Systems - Zimperium

In an era where flexibility and efficiency define consumer interactions, the adoption of software-only point of sale (SoftPOS) applications is rapidly transforming the retail industry. SoftPOS, also known as “Tap on Phone”, allows merchants to use their NFC-enabled smartphones or tablets to accept contactless payments directly—no specialized hardware is required. This shift not only democratizes payment processing across businesses of all sizes but also introduces significant convenience for both shoppers and sellers.

The Security Imperative

However, with great convenience comes great responsibility—specifically, the responsibility to ensure the security of every transaction processed. SoftPOS solutions operate alongside numerous other applications on consumer-grade devices, which expose them to new attack vectors and vulnerabilities. It is crucial to ensure security in the following areas:

1. Compliance and Certification: To establish trust and ensure secure operations, all SoftPOS solutions must adhere to stringent security standards. These include PCI security standards and EMVCo certifications, which are crucial for demonstrating the security capabilities of the devices and the applications. SoftPOS systems undergo multiple levels of certification, focusing on everything from the device’s NFC capabilities (EMVCo L1) to the functionality of the contactless kernel (L2) and comprehensive security evaluations (PCI MPoC). 

2. Data Integrity and Confidentiality: The integrity of the SoftPOS application and its interaction with the backend systems is essential. It ensures that transaction data is accurately and securely handled, maintaining both confidentiality and integrity to prevent data compromise incidents.

Vulnerabilities in Mobile SoftPOS Applications

Despite the certification requirements of SoftPOS applications, they are not immune to cyber threats. Common vulnerabilities include:

• Memory Scraping: This involves attackers accessing unauthorized data directly from the device’s memory, which might include sensitive payment information.
• Malware Attacks: Malicious software can be designed to infiltrate mobile applications, leading to data breaches or unauthorized transactions.
• Insufficient Encryption: Without comprehensive encryption practices, sensitive data, and key transaction details can be exposed to potential interception or manipulation.
