Best Practices
This article is the second in a series illuminating the developer’s perspective on mobile app security by guest contributor and developer Evan Rose — managing partner at Rose Digital. The first post covered planning mobile API security, and in this installment Evan explains what developers need to keep in mind as they code their mobile apps. […]
This is part two of three in a series about building a mobile app security program from NowSecure Director of Services Katie Strzempka. Part one defines a mobile app security program and summarizes how to create a high-efficiency team. Part two explains how to choose the right mobile app security testing tools to drive consistency in […]
Certificate Pinning and Hostname Verification: Don’t Get Pinned by a Mobile Man-In-The-Middle Attack
Recent news stories have brought attention to a research paper (“Spinner: Semi-Automatic Detection of Pinning without Hostname Verification”) published this week highlighting man-in-the-middle (MITM) vulnerabilities in a number of public mobile apps. The vulnerability springs from a failure to validate that the hostname on the certificate matches the actual host to which an app connects.
There is no denying that mobile applications have become ubiquitous. For many companies, building an app is a foregone conclusion. We have applications for social, for fitness, for productivity, for organization and even for things as sensitive as our finances. We are all increasingly turning over more of our personal information and data to applications […]
Researchers unveiled a startling discovery this week: 41 percent of the most popular Android apps that implement OAuth 2.0 allow an attacker to remotely impersonate any user account, access personal information from within the app, and make in-app purchases on the user’s dime. In this post I explain OAuth 2.0 and how it affects mobile app security and risk.
Security leaders are tasked with quickly and consistently managing mobile risk within and beyond their organization’s walls, a task that will only get more difficult as mobile app usage and development continues to rise. The purpose of this post is to familiarize developers, QA professionals, and security analysts with the OWASP MASVS, as well as provide additional guidance from the NowSecure Secure Mobile Development Best Practices about how to avoid or remediate the top ten risks.
The long-term costs of design choices that maximize short-term convenience. They far outweigh the benefits.
I’ve recently noticed a spike in questions from our customers — and specifically security analysts — about App Transport Security (ATS), or NSAppTransportSecurity, for iOS apps. ATS is a critical security practice for our customers in financial services and other regulated industries. A lot of ATS documentation already exists, but questions persist. A core part […]
Many government agencies are not taking full advantage of the productivity gains and cost savings that can come from using mobile apps, and part of that hesitation probably comes from concerns about security.
Implementing certificate pinning in mobile apps that handle highly sensitive data provides too much benefit to be passed over. Users can be tricked into installing a malicious self-signed certificate on a mobile device, setting the stage for a man-in-the-middle attack. In those situations, certificate pinning can still prevent the interception of an app’s network traffic.
