Preventing SQL injection in C# with Entity Framework

SQL injection (SQLi) is one of the most severe security vulnerabilities in web applications. It occurs when an attacker is able to manipulate the SQL queries executed by an application by injecting malicious SQL code into user input fields. SQLi can lead to unauthorized access to sensitive data, data corruption, or even complete control over the database server.

Best Practices for Cybersecurity in .NET Applications

In today's digitally interconnected world, cybersecurity is not just a priority-it's a necessity. For developers working with.NET applications, ensuring robust security measures can protect sensitive data, maintain user trust, and prevent costly breaches. Here are the essential best practices for enhancing cybersecurity in.NET applications. Keeping your.NET applications updated is crucial for maintaining security. For example, migrating from.NET Core 3.1 to.NET 6 can bring significant security enhancements and performance improvements.

Uncover vulnerabilities in C# applications using Coverity Rapid Scan Static | Synopsys

In this video you will discover how Coverity’s Rapid Scan Static Analysis can help developers find and fix vulnerabilities in their code early in the development cycle by providing quick feedback on the most impactful issues. This new update in the Coverity 2024.6.0 release highlights how developers can run quick scans for C# applications via the Coverity Rapid Scan Static engine; returning quick and accurate static analysis results related to issues such as deserialization, hardcoded secrets, unsafe API calls, single-file data flow, etc. at record speeds.

Securing Samba Ports: Essential Practices for Safeguarding Your Network

In the vast and interconnected world of information technology, the security of network services and protocols is paramount for organizations of all sizes. Among these, Samba—a free software re-implementation of the SMB/CIFS networking protocol—plays a crucial role in facilitating file and print services across various operating systems, including Unix, Linux, IBM System 390, and Windows.

.NET developers alert: Moq NuGET package exfiltrates user emails from git

On August 8, 2023, the.NET community was informed that the testing library called Moq exfiltrates developer's emails from their development machine and sends them off to third-party remote servers. Snyk has already published a security advisory and will alert developers who scan and monitor their.NET projects with Snyk.

New .NET Malware "WhiteSnake" Targets Python Developers, Uses Tor for C&C Communication

The JFrog Security Research team recently discovered a new malware payload in the PyPI repository, written in C#. This is uncommon since PyPI is primarily a repository for Python packages, and its codebase consists mostly of Python code, or natively compiled libraries used by Python programs. This finding raised our concerns about the potential for cross-language malware attacks.

Attackers are starting to target .NET developers with malicious-code NuGet packages

Malicious packages are often spread by the open source NPM and PyPI package repositories, with few other repositories affected. Specifically – there was no public evidence of severe malicious activity in the NuGet repository other than spam packages used for spreading phishing links. As with other repositories, the JFrog Security Research team regularly monitors the NuGet repository for malicious packages, including manual analysis of suspicious code.

Best practices for containerizing .net applications

Containerization with Docker has become a major trend in web application development that many.NET developers have adopted. There are many compelling advantages for developers and DevOps engineers to containerize.NET applications, even when working with the older.NET Framework 4.x versions. However, if we don’t know how to use containers properly, we’ll experience little benefit from them.
