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.

ESET researchers uncovered a cyberespionage campaign by BladedFeline, an Iran-aligned APT group likely tied to OilRig. The group has targeted Kurdish and Iraqi government officials since at least 2017, using various malicious tools including the Whisper backdoor, PrimeCache IIS module, and reverse tunnels. BladedFeline maintains persistent access to high-ranking officials in both the Kurdistan Regional Government and Iraqi government, likely for espionage purposes. The group's toolset includes sophisticated backdoors, webshells, and custom tunneling applications. ESET assesses with medium confidence that BladedFeline is a subgroup of OilRig, based on shared code, targets, and tactics. The campaign also extended to a telecommunications provider in Uzbekistan.
