Hydraq is a data-theft trojan first used by Elderwood in the 2009 Google intrusion known as Operation Aurora, though variations of this trojan have been used in more recent campaigns by other Chinese actors, possibly including APT17.[1][2][3][4][5][6][7][8]
Enterprise ATT&CK only. Any Mobile or ICS rows on the same ATT&CK page are not carried.

Standing S0203
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
77th percentile · 77% of 825 ATT&CK software entries have this many Enterprise techniques or fewer.
89th percentile · 89% of 825 ATT&CK software entries have this many tactics spanned or fewer.
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
Coverage
60th percentile · 60% of 825 ATT&CK software entries have this many detection rules per technique or fewer.
Detection coverage S0203
782 distinct rules cover the 19 techniques recorded for this tool. The 824 technique-to-rule mappings resolve to 782 distinct rules, because one rule can cover several techniques. 530 Sigma · 252 Splunk.
