The Netwalker DLL has been injected reflectively into the memory of a legitimate running process.6
Netwalker has been written in PowerShell and executed directly in memory, avoiding detection.78
Operators deploying Netwalker have used batch scripts to retrieve the Netwalker payload.9
Standing S0457
Reach is how much of ATT&CK this tool touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.

75th percentile · 75% of 825 ATT&CK software entries have this many Enterprise techniques or fewer.

Threat groups061% tie · 22 values
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
Campaigns085% tie · 8 values
85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
