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.

A targeted intrusion campaign impacting Israeli organizations has been identified, leveraging compromised internal email infrastructure to distribute phishing messages. The attack uses a multi-stage, PowerShell-based infection chain, culminating in the delivery of a remote access trojan (RAT). Key characteristics include a full PowerShell-based delivery chain, obfuscated payloads, evidence of lateral movement, and potential overlap with MuddyWater campaigns. The attack begins with phishing emails, progresses through a spoofed Microsoft Teams page, and uses social engineering to execute malicious PowerShell commands. The payload retrieves additional data, deploys a RAT, and establishes communication with a command and control server. The campaign demonstrates the effectiveness of living-off-the-land techniques, layered evasion, and adaptive C2 communication.
