BlackTech is a suspected Chinese cyber espionage group that has primarily targeted organizations in East Asia--particularly Taiwan, Japan, and Hong Kong--and the US since at least 2013. BlackTech has used a combination of custom malware, dual-use tools, and living off the land tactics to compromise media, construction, engineering, electronics, and financial company networks.[1][2][3]
Enterprise ATT&CK only. Any Mobile or ICS rows on the same ATT&CK page are not carried.

Standing G0098
Reach is how much of ATT&CK this group 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 176 ATT&CK groups 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
43rd percentile · 57% of 176 ATT&CK groups have more Enterprise techniques.
34th percentile · 66% of 176 ATT&CK groups have more tactics spanned.
67th percentile · 67% of 176 ATT&CK groups have this many tools and malware or fewer.
89% of the population shares a single value across only 4 distinct values, so a percentile here would rank the tie, not the entity.
Coverage
41st percentile · 59% of 176 ATT&CK groups have more detection rules per technique.
Detection coverage G0098
603 distinct rules cover the 14 techniques recorded for this group. The 642 technique-to-rule mappings resolve to 603 distinct rules, because one rule can cover several techniques. 381 Sigma · 222 Splunk.
