Obfuscation Density: high encoded/escaped-token density

Trust signals

Why this verdict

PkgRadar discounts a release’s score when public reputation argues against novel malware. The verdict above already reflects these — the panel just explains what was applied.

Weekly downloads: 16,111Mainstream · −50% score
Versions published: 522Mature · −50% score
First published: Jan 2017
Publisher: microsoft1es

Effective trust discount applied: −50% (max across signals — discounts don’t stack). New install-lifecycle deltas vs the previous release would clear the discount.
