Nx Console vulnerability

Nx Console contained embedded malicious code that allowed a compromised version to harvest credentials from disk and memory via obfuscated payloads.

Verdict

Today item, not a backlog item.

A malicious Nx Console extension was published, fetching obfuscated code to extract credentials from multiple sources. The vulnerability enabled supply-chain compromise with active exploitation and ransomware deployment.
