| Factor | Weight | Score | Contribution | Where it came from |
|---|---|---|---|---|
| Corroborationleads | 0.35 | 0.39 | +0.135 47% | 1 independent org on the story. Tier-3 aggregators never corroborate — they can show something is circulating, never that it is true. |
| Source trust | 0.25 | 0.47 | +0.117 41% | BleepingComputer is the highest-trust source on this story. Trust is taken from the best source, not averaged. |
| Pickup rate | 0.20 | 0.00 | +0.000 0% | One counted organisation, so there is no spread to measure — nothing has picked this up to set a rate. |
| Freshness | 0.20 | 0.17 | +0.035 12% | Halves every 10 hours from the newest item on the story. This is the only factor that rewards a story for nothing more than being recent. |
