Industry breach research reported that system intrusions accounted for around 80% of Asia-Pacific breaches in its 2025 edition, up from 38% the previous year, with malware present in 83% of regional breaches against 58% previously, and ransomware in 51%.
A Category Doubling In A Year Needs Explaining
System intrusions going from roughly a third to four fifths of breaches in twelve months is not a plausible change in adversary behaviour. Attack patterns do not move that fast, and nothing else in this corpus records a comparable shift over 2025.
The likelier explanations are a change in what falls into the category, a change in the contributing dataset, or a change in the regional sample. Large annual studies aggregate incidents from contributors who join and leave, and the population being measured is not stable.
This desk applies the same reading to the 2025 healthcare and retail figures at 25-0630 and 25-0808. A number that moves faster than the world does is measuring the instrument.
What Survives Is The Regional Contrast
The useful output of a study like this is not the absolute level but the difference between regions measured the same way in the same year. If APAC shows a materially higher malware share than other regions on identical methodology, that is a finding the methodology problem does not destroy.
Graded medium accordingly: the year-on-year figures should not be quoted, and the cross-regional comparison is the part worth keeping.
