- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 1.2.0
- **Selected version is latest:** No
- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)
