Sanctioned, Seized, Still Scanning: Inside a Russian Bulletproof Hosting Network Targeting the EU
On 18 May 2026, Dutch investigators seized more than 800 servers and broke up a hosting operation that prosecutors say powered Russian cyberattacks across the EU. We had spent the previous year watching the same network from the other side. After the seizure, the scanning did not stop.
New Integrations for Microsoft Sentinel and MISP
ELLIO is expanding its threat intelligence ecosystem with two new integrations designed for SOC, detection engineering, and threat intelligence workflows: Microsoft Sentinel via TAXII 2.1 and a native MISP integration.
ELLIO expands with 10 new recon and scanner IP feeds
ELLIO Threat Intelligence & Blocklist Automation has been updated with 10 new scanner and recon IP address feeds. This improves detection and control of scanning activity at the network perimeter, enabling more accurate allow and block rules without manual IP range management.
Stories from ELLIO
Why Microsoft Sentinel Feels Noisy: It’s Not Volume, It’s Recon Blindness
Alert fatigue in Microsoft Sentinel is not caused by alert volume alone. It is a context and correlation problem. Read how reconnaissance-aware threat intelligence helps separate internet scanning noise from active exploitation activity to improve signal quality and reduce false-positive incidents.
Threat Intelligence Platforms by Use Case: 2026 Guide
Not all CTI platforms are built for the same purpose. Differences in data sourcing, architecture, and enrichment capabilities mean the “best” platform is defined by its fit for operational use cases, such as reducing SIEM noise, supporting threat hunting, or detecting fraud.
Internet Background Noise: The Hidden Cost Layer in Security Operations
The same layer that drives cost also carries early attack signals. With visibility into reconnaissance, teams separate signal from noise and stop attacks before they become operationally burdensome and costly.
