GlassWorm Returns: 24 Malicious Extensions Target Developers
🔍 The GlassWorm supply-chain campaign has resurfaced with 24 malicious extensions distributed across the Microsoft Visual Studio Marketplace and Open VSX, impersonating popular developer tools such as Flutter, React and Tailwind. Researchers say attackers inflated download counts and slipped malicious updates after initial approval to evade filters. Analysis found Rust-based implants that load platform-specific libraries (os.node and darwin.node) to fetch Solana-based C2 details and download encrypted JavaScript payloads, while a Google Calendar fallback is also used. Developers and repository maintainers are urged to audit installed extensions and review update histories.
