Data Theft Repackaged: A Case Study in Malicious Wrapper Packages on npm
The Socket Research Team breaks down a malicious wrapper package that uses obfuscation to harvest credentials and exfiltrate sensitive data.
Since the authors of the original package decided to stage their dumb protest that makes most of the community unable to access their package without vulnerabilities, I decided to make this project. It automatically takes a fresh version of SheetJS from their git repository, and publishes to npm if the version is different. The whole process is automated and works through Github Actions. https://github.com/e965/sheetjs-npm-publisher
The SheetJS Community Edition offers battle-tested open-source solutions for extracting useful data from almost any complex spreadsheet and generating new spreadsheets that will work with legacy and modern software alike.
SheetJS Pro offers solutions beyond data processing: Edit complex templates with ease; let out your inner Picasso with styling; make custom sheets with images/graphs/PivotTables; evaluate formula expressions and port calculations to web apps; automate common spreadsheet tasks, and much more!
