ChChes is a Trojan that appears to be used exclusively by menuPass. It was used to target Japanese organizations in 2016. Its lack of persistence methods suggests it may be intended as a first-stage tool. [1][2][3]

ChChes copies itself to an .exe file with a filename that is likely intended to imitate Norton Antivirus but has several letters reversed (e.g. notron.exe).4

Reach is how much of ATT&CK this malware 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.
