🛡️ Kaspersky developed a machine-learning model to detect DLL hijacking, a technique where attackers replace or sideload dynamic-link libraries so legitimate processes execute malicious code. The model inspects metadata such as file paths, renaming, size, structure and digital signatures, trained on internal analysis and anonymized KSN telemetry. Implemented in the Kaspersky Unified Monitoring and Analysis Platform, it flags suspicious loads and cross-checks cloud reputation to reduce false positives and support retrospective hunting.

🔒 Cloudflare describes recent security hardening applied to Cloudflare Workers, combining V8 runtime changes with CPU features to strengthen isolation of customer scripts. The post highlights use of memory protection keys (PKU) assigned per-isolate, adoption of V8's sandbox and compressed pointers to confine heap corruption, and custom memory placement to pack sandboxes efficiently. Together these mitigations improve defense-in-depth and reduce opportunities for cross-isolate data leaks.

🛡️ The shift to containers, Kubernetes, and serverless has made runtime visibility the new center of gravity for cloud-native security. CNAPPs that consolidate detection, posture, and response are essential, but observing active workloads distinguishes theoretical risk from live exposure. AI-driven correlation and automated triage reduce false positives and accelerate remediation. Vendors such as Sysdig stress mapping findings back to ownership and source code to drive accountable fixes.
