What is PDFsharp

PDFsharp is a .NET library used for creating and processing PDF documents. It is a powerful tool that allows developers to create documents based on an object model with paragraphs, tables, styles, etc., and render them into PDF or RTF. It supports common raster image formats and is compatible with .NET 6 or higher. Developers can use PDFsharp to perform tasks such as editing, converting PDF documents, and even creating PDF annotations. However, it’s important to note that there is a malicious program that impersonates the legitimate PDFsharp program. This malware is often installed by users, knowingly or unknowingly, through advertisements, cracks for games, or bundled with other software. Once installed, the fake PDFsharp program waits until an Internet connection becomes available to connect to a remote server or website. This Trojan may install adware, Trojans, rootkits, and other types of malware.
