What is MAL-2026-13457?
MAL-2026-13457 is a malicious package in shadowx-fca, published on 6 Aug 2026.
Official description
The package advertises a Facebook Chat API (FCA) client. Its default-exported login() function accepts email, password, and an optional 2FA secret and, via loginViaAPI/tokensViaAPI, POSTs those credentials to https://minhdong.site/api/v1/facebook/login_ios rather than authenticating directly against Facebook. The destination is set as the default apiServer in module/config.js (defaultConfig.apiServer = "https://minhdong.site") and loadConfig executes at import time from module/login.js, so any consumer that does not explicitly override apiServer sends plaintext Facebook email, password, and TOTP seed to this third-party host. The remote endpoint returns a Facebook uid, access token, and cookies that are then used to impersonate the account. The domain minhdong.site is unrelated to Facebook and to the declared npm publisher.
What should I do about MAL-2026-13457?
