From help desk impersonation to AD CS abuse: Investigating ESC1 and ESC8 intrusion pathsMicrosoft Threat Intelligence analysis of two human-operated intrusions that began with Teams help desk impersonation and Quick Assist sessions, then diverged at AD CS. Case 1 abused an ESC1 template for privileged certificates and DCSync, with an excluded account later used for Rclone exfiltration. Case 2 used PetitPotam and ESC8 relay to get a domain controller certificate and PKINIT. Includes investigation steps, AD CS hardening and KQL hunting queries.

Perceiving and Predicting Dynamic Sports: Spatiotemporal Intelligence in Vision Models for Egocentric Tennis VideoThis paper presents an annotated egocentric tennis dataset (egocentric video synced with five allocentric views, global positions, contact times, stroke types) and evaluates image encoders, video encoders and vision-language models on seven prediction tasks. Best models reach 0.14 m player and 0.54 m ball localization error and 0.14 s contact-time error. Depth input helps 3D ball localization, and longer histories do not help forecasting. A conditional diffusion model generates whole-body tennis motion in real time.

LiteLLM suspects its October 21 release compromise began with Claude Code responses containing GitHub CLI OAuth tokens that were written to logs of an internet-facing internal LiteLLM gateway. Attackers allegedly stole those tokens, used an organization-owner token to disable branch protections, and pushed poisoned artifacts from a lookalike repository. How they entered the gateway is unconfirmed, and this is not a proven Claude Code vulnerability.
