GCVE-110-CERTFI-2025-0046

This week, we highlight a severe alert we have issued concerning M365 account compromises and attempted breaches. The target audience for the alert includes all companies and other organisations—as well as their employees—who use M365 products. We also introduce the August edition of Cyber weather and provide a summary of the Kriittinen koodi (Critical Code) webinar held this week, which focused on software security as a key element of security of supply. Finally, we take a closer look at the Hummer malware.
