Security researchers from Socket have discovered a troubling digital trap targeting Russian-language users within JavaScript packages. Two npm packages, named @link-loom/ui-sdk and @link-loom-react-sdk, initially appear benign, designed to assist developers in creating visually appealing pop-up notifications for web applications. However, hidden beneath this seemingly harmless surface lies a politically motivated functionality.
When a user, whose language settings are set to Russian, visits a website that employs these JavaScript packages, a jarring experience ensues. The website becomes unresponsive, freezing interaction completely, while the Ukrainian national anthem plays on repeat. This surprising outcome is not trivial—these packages have accumulated thousands of downloads, potentially affecting numerous developers who have integrated the code into their projects.
The original package garnered over 7,000 downloads before being deprecated, yet its successor retained the problematic code. The sophistication of this coded protest is notable. The misleading functionality is buried approximately 5,000 lines deep within a dense codebase exceeding 100,000 lines.
It activates only under specific conditions: users must have Russian language settings, visit a Russian or Belarusian website, and it cannot be their first visit. While some may view this as a harmless political statement, it poses serious concerns regarding software supply chain security. Imagine the frustration for an online shop or essential service if a segment of users is rendered unable to access their site due to hidden code no one was aware of.
Although the creator has since stripped newer versions of this functionality, the risk remains for sites still relying on the corrupted versions. This incident underscores the pressing need for developers to be vigilant about the packages integrated into their projects. While third-party code offers conveniences, it also introduces significant risks that could have far-reaching consequences.
As global geopolitical tensions persist, developers increasingly use their skills to manifest political messages through code, raising questions about the implications of such actions within the tech community.
