The delivery-ci-notify npm package version 35.2.5 contains malicious code that downloads and executes a native binary payload from hardcoded Cloudflare worker hosts or via a DNS TXT record covert channel. The payload is saved under disguised filenames and executed detached from the main process, using techniques to evade static detection and impersonate legitimate dotnet diagnostic files. The package masquerades as a CI notification tool but includes intentional evasion mechanisms consistent with malicious intent.
