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.
A sophisticated espionage campaign has been identified leveraging malware that exploits Microsoft Graph API to transform compromised Microsoft 365 calendars into covert command-and-control infrastructure. The malware creates calendar events dated to 2050 with encrypted attachments to exfiltrate files and receive instructions. A secondary DNS tunneling channel using IPv6 AAAA records refreshes Microsoft Entra ID credentials for authentication. Communications are secured using hybrid RSA and AES-256-GCM encryption with separate key pairs for inbound and outbound channels. Twelve infected systems have been identified, primarily targeting Israeli entities, with only three actively communicating with attackers. The operation demonstrates high technical sophistication and disciplined targeting, suggesting a well-resourced adversary conducting focused espionage operations since at least June 2026.
