    Question

    Zscaler Report Cites 275% Rise in AI Ransomware and $328M in Extortion

    Direct answer

    The 2026 Ransomware Report from Zscaler underscores an evolving enterprise security risk profile. Threat actors are deploying AI tooling to execute massive data breaches, totaling roughly 900 terabytes across targeted organizations. Extortion demands have reached high dollar values, causing aggregate enterprise losses of $328 million. Enterprise collaboration platforms, including Microsoft Teams, are cited as primary vectors for executive credential compromise and payload delivery. The findings suggest enterprise IT leaders will face renewed urgency to prioritize identity-based zero-trust security platforms.
