Kaspersky identified a new .NET Native AOT communication module for Project CAV3RN, a sophisticated cyberespionage framework targeting Israel. This module replaces the previous HTTP/WebSocket component by exchanging commands through Outlook calendar events accessed via Microsoft Graph API. Commands and results are stored in a fixed time window (2050-05-13 22:00-23:00 UTC) using specific subject patterns to identify heartbeats, commands, and outputs. The module implements RSA and AES-GCM encryption for secure communications. If Microsoft Graph authentication fails, it retrieves replacement configuration settings through DNS AAAA record responses from actor-controlled nameservers. The infrastructure analysis and behavioral patterns suggest low-confidence attribution to OilRig (APT34), based on the use of Microsoft-hosted services for command and control and compromised regional infrastructure.

An exposed command and control server on RouterHosting infrastructure revealed an active Iranian-nexus intrusion campaign targeting twelve Omani government ministries. The operation primarily focused on the Ministry of Justice and Legal Affairs, deploying custom webshells that provided persistent access through April 2026. Over 26,000 user records containing judicial case data, committee decisions, and registry hives were exfiltrated. The attacker utilized ProxyShell exploits, DotNetNuke vulnerabilities, and custom Python scripts targeting Exchange servers, SQL databases, and Oracle systems. Infrastructure analysis revealed connections to spoofed Iranian diaspora media and censorship circumvention tools, with tactical overlaps indicating MOIS-linked groups such as APT34 and MuddyWater. The campaign specifically targeted judicial records, immigration systems, and citizen identity data across multiple government entities.
