Enterprise ATT&CK only. Any Mobile or ICS rows on the same ATT&CK page are not carried.
Evilnum has used malicious JavaScript files on the victim's machine.2
Evilnum can deploy additional components or tools as needed.4
Evilnum has sent spearphishing emails designed to trick the recipient into opening malicious shortcut links which downloads a .LNK file.5
EVILNUM has used the malware variant, TerraTV, to run a legitimate TeamViewer application to connect to compromised machines.6
Evilnum has used a component called TerraLoader to check certain hardware and file information to detect sandboxed environments. 7
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.
35th percentile · 65% of 176 ATT&CK groups have more Enterprise techniques.
39th percentile · 61% of 176 ATT&CK groups have more tactics spanned.
47th percentile · 53% of 176 ATT&CK groups have more tools and malware.
89% of the population shares a single value across only 4 distinct values, so a percentile here would rank the tie, not the entity.
79th percentile · 79% of 176 ATT&CK groups have this many detection rules per technique or fewer.
463 distinct rules cover the 11 techniques recorded for this group. 344 Sigma · 119 Splunk.
