Malicious code in @osl-design/react (npm)

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

--- _-= Per source details.

That script loads `runtime/support/telemetry/probe/impl.js`, which reads the installer's OS username (`os.userInfo().username`), hostname (`os.hostname()`), and current working-directory basename, concatenates them with a prefix into a DNS label, and issues a `dns.resolve4` query against the hardcoded domain `oob.algamil7x.xyz` — a DNS out-of-band exfiltration channel. Sensitive strings, including the module names `os`/`dns`, the API names `userInfo`/`hostname`/`cwd`/`resolve4`, the label prefix `osldr`, and the destination domain `oob.algamil7x.xyz`, are hidden as hex/char-code arrays decoded at runtime, and `os` and `dns` are loaded through `module.constructor._load(...)` rather than literal `require()` calls to evade static analysis. The README contradicts the shipped behavior by asserting the package has no file system access and no network requests beyond registry probes, and the scope name `@osl-design/react` resembles a design-system package to lend plausibility. Installing this package leaks host-identifying information about the installer's machine to an attacker-controlled DNS resolver.
