The Zscaler Virus Download threat blocked analytic is designed to monitor and identify attempts to download viruses that have been blocked by Zscaler's web proxy service within a corporate network. It operates by analyzing web proxy logs to detect blocked actions specifically related to virus downloads. Critical fields such as device owner, user identity, URL category, destination URL, and source IP address are scrutinized to flag suspicious activities. This detection approach is highly valuable as it allows security teams to identify potential threats early, facilitating timely intervention to prevent potential breaches or further infections by leveraging key indicators of compromise. By promptly addressing these alerts, organizations bolster their defenses against malware and malicious actors.
