AI Security Verdict

Moderate Risk

Confidence: 55%

4
Risk Score

Bare JavaScript loader file from a random free workers.dev subdomain. No forms, no threat-intel, no malware patterns, no exfiltration observed, but the script's purpose is unverifiable and the host is anonymous — moderate suspicion only.

Risk Factors (3)
Opaque, uninspectable JavaScript delivered as a raw file from a free hosting-platform subdomain with no surrounding context
Randomly generated subdomain name with a 'js_loader' path hint, consistent with a disposable payload-delivery endpoint
Effective subdomain creation date unknown — cannot be corroborated by domain age
Safety Factors (5)
Zero forms and zero password, payment or disguised-password fields — no credential or payment collection present
No Indicators of Compromise matched against the page or any loaded resource
No JavaScript malware patterns detected; no obfuscation, DevTools blocking or credential exfiltration behaviour observed
No third-party script hosts — all JavaScript originates from the same domain
The two Suricata alerts are ET INFO notifications about the workers.dev platform itself (DNS query and TLS SNI), not malware or phishing signatures
Domain age information unavailable
