Iranian Poachers Hunt Diplomats

An Iran-nexus group linked to Homeland Justice has mounted a coordinated, multi-wave spear-phishing campaign aimed at embassies, consulates, ministries of foreign affairs, and international organizations worldwide. By disguising malicious messages as legitimate diplomatic communications, the attackers leveraged over 100 compromised accounts—including one from the Oman Ministry of Foreign Affairs in Paris—to distribute weaponized documents during a period of escalating Iran–Israel tensions. This operation illustrates how Tehran continues to sharpen its espionage tradecraft to infiltrate trusted diplomatic channels, exfiltrate sensitive intelligence, and undermine geopolitical rivals.
Phase 1: The Lure and Delivery
The first phase revolved around credibility and scale, ensuring that the bait was irresistible.
Themes that resonate: Emails referenced urgent MFA communications and geopolitical disputes involving Iran and Israel, exploiting diplomats’ need for timely information.
Hijacked legitimacy: Instead of relying solely on spoofed addresses, the attackers used 104 real, compromised email accounts belonging to ministries, embassies, and quasi-government entities, giving their messages extraordinary trustworthiness.
Target distribution: The campaign was not limited to one region. Recipients included diplomatic missions across Europe, Africa, the Middle East, Asia, and the Americas, with European embassies and African organizations most heavily targeted.
Weaponized attachments: Each email contained a malicious Microsoft Word document. When opened, recipients were prompted to “Enable Content,” a social engineering tactic well known to work in bureaucratic workflows where macros are often tolerated.
Multi-wave orchestration: Rather than a single burst, the group launched the campaign in several waves, adjusting timing and volume to increase success rates and evade mass detection.
This phase highlights how compromised trust + geopolitical urgency + staged delivery created near-perfect conditions for the attack to succeed.
Phase 2: Breach and Execution
Once the bait was taken, the breach unfolded silently.
Macro execution: Enabling content triggered VBA macros that downloaded and ran a malware executable.
Persistence mechanisms: The malware embedded itself to survive reboots, ensuring continuous access.
C2 communication: Infected systems immediately contacted attacker-controlled command-and-control servers, giving operators remote management over compromised hosts.
Multi-wave depth: Because the operation was coordinated in layers, attackers could refine delivery, bypass filters, and sustain the infection chain across multiple regions.
The goal here was not immediate disruption but the establishment of stealthy, persistent footholds inside highly sensitive diplomatic environments.
Phase 3: Espionage and Exploitation
After establishing access, the campaign shifted toward intelligence harvesting.
System reconnaissance: Malware collected host details, creating an operational picture of embassy networks.
Diplomatic espionage: Access to MFA inboxes gave attackers visibility into confidential communications, negotiation drafts, and strategic instructions—information of high value for Iranian intelligence.
Espionage vs. disruption: Unlike ransomware operations, this was carefully espionage-focused, with persistence and stealth prioritized over noise or financial gain.
Continuity with past activity: Similar methods were observed in 2023 attacks against Mojahedin-e-Khalq in Albania, pointing to the same ecosystem of Iranian-aligned threat actors refining their phishing tactics over time.
Operational impact: Compromised diplomatic accounts could also be weaponized in secondary attacks, amplifying reach and credibility across other governments and organizations.
This phase effectively turned the global diplomatic email ecosystem into an espionage tool, repurposing trusted channels against their owners.
Measures to Fend Off
Defending against such state-aligned, multi-wave campaigns requires a mix of technical controls, organizational readiness, and user awareness:
Block macro-enabled documents: Disable or restrict VBA macros in Word files across ministries and embassies.
Enforce MFA universally: Apply multi-factor authentication to all diplomatic and government accounts, minimizing the impact of compromised credentials.
Validate senders rigorously: Deploy SPF, DKIM, and DMARC, and cross-check “urgent” diplomatic instructions with secondary channels.
Monitor outbound anomalies: Detect and investigate unexpected communications with C2 infrastructure.
User awareness training: Train diplomatic staff to distrust urgent attachments—even from known accounts—without secondary validation.
Incident readiness: Maintain response playbooks for MFA-themed phishing and ensure embassies have rapid channels for IT and security coordination.
Threat intelligence integration: Subscribe to regional threat intelligence feeds to correlate Iran-aligned infrastructure and block it preemptively.
The Iranian spear-phishing waves tied to Homeland Justice show how diplomacy has become a battlefield not just of words, but of code. By hijacking trusted diplomatic accounts and disguising malware as urgent communications, attackers exploit the very channels meant to build trust between nations. The campaign’s scale and coordination reveal a threat that is persistent, adaptive, and tailored to undermine international institutions. For defenders, the lesson is clear: vigilance must extend beyond traditional borders, ensuring that even the most routine messages are questioned, validated, and fortified against manipulation. In today’s climate, securing diplomacy means securing the inbox.
