GoldFinder is a custom HTTP tracer tool written in Go that logs the route a packet takes between a compromised network and a C2 server. It can be used to inform threat actors of potential points of discovery or logging of their actions, including C2 related to other malware. GoldFinder was discovered in early 2021 during an investigation into the SolarWinds Compromise by APT29.[1]

MITRE reference S0597
GoldFinder has used HTTP for C2.3
GoldFinder logged and stored information related to the route or hops a packet took from a compromised machine to a hardcoded C2 server, including the target C2 URL, HTTP response/status code, HTTP response headers and values, and data received from the C2 node.4
Standing S0597
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.
Reach
Techniques3Bottom 12%
12th percentile · 88% of 825 ATT&CK software entries have more Enterprise techniques.
Tactics3Bottom 21%
21st percentile · 79% of 825 ATT&CK software entries have more tactics spanned.
Threat group161% 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.
Campaign185% 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.
