Dependency confusion and typosquatting campaign by threat actor "saif777". Packages use inflated version numbers (9999.9999.9999, 9999.9999.10000, 50.50.50, 7.66.5) to win version resolution in environments with private registries. All active packages execute a postinstall hook ("node index.js") that collects a system fingerprint — public IP (via api.ipify.org), username, hostname, CPU model, RAM, working directory, OS platform — and exfiltrates it as a Discord embed to a shared webhook (base64-obfuscated in source). Payloads include sandbox/bot detection: machines with ≤1 CPU or <2 GB RAM are flagged as sandbox/CI; real machines trigger a green embed. Typosquats the official @google-cloud/storage package. After exfiltrating system data the payload attempts to silently proxy to the legitimate @google-cloud/storage library (if installed) to avoid detection and maintain normal application behaviour.
