The largest increase in malware was in the education sector, where volume climbed 157 percent. However, this number accounts for combined attacks against higher education and K–12 institutions; attacks specifically targeting higher education customers rose 26 percent, while attacks targeting K–12 more than tripled.
Malware attacks targeting Internet of Things devices also rose, climbing 87 percent year over year overall. The education sector saw a 146 percent increase in these attacks since 2021. According to the report’s authors, this increase can be attributed to weak security controls on smart devices, suggesting a need for stronger regulation.
