Week in review: Researcher breaks into Microsoft analytics service, NetScaler RCE 0-day exploited
Last week’s security news was dominated by active exploitation of multiple zero-days in Citrix NetScaler, Apple, Cisco SD-WAN, and FortiMail, alongside a major breach of OpenInfra Europe’s JFrog Artifactory and a reported FBI portal compromise linked to ShinyHunters. The roundup also highlighted growing AI-related risks, including malicious Custom GPT abuse, leaked company screenshots from coding agents, and research showing AI systems can expose secrets and weaken security controls. #Citrix #NetScaler #Apple #Cisco #FortiMail #OpenInfraEurope #JFrogArtifactory #ShinyHunters #DIVD #KillSec

Keypoints
