| Binary provenance | 6 on a recognised distribution platformThe strongest signal against a repackaged installer: the file should come from the publisher, not from a mirror nobody vouches for. | 29.8 / 35 |
| Served over HTTPS | 6 of 6 over HTTPSAn installer fetched over plain HTTP can be modified in transit. | 15 / 15 |
| Release recency | last release about 1 months agoSoftware that has not shipped in years accumulates unpatched vulnerabilities. | 15 / 15 |
