APT34’s Saitama Agent: Phishing and DNS Tunneling in Jordan
- Actor Motivations: Espionage,Exfiltration
- Attack Vectors: Backdoor,Dropper,Malicious Macro,Malware,Spear Phishing
- Attack Complexity: Medium
- Threat Risk: Unknown
Threat Overview
APT34's Saitama Agent employs a spear phishing email with a malicious Excel attachment to deliver malware using unique DNS tunneling and stateful programming techniques. The Excel document contains a VBA macro that hides its activities and communicates with the C2 server using DNS requests. The macro checks for mouse connections, drops multiple files, and uses a scheduled task for persistence. The campaign appears to be targeting Jordan, leveraging a Jordanian government ministry's logo to deceive victims.

Understanding the APT34 Saitama Malware Attack
A new malware called "Saitama," linked to the APT34 group, was delivered through a phishing email containing a malicious Excel attachment. When the file is opened and macros are enabled, the malware installs a stealthy backdoor.
The attack is attributed to APT34, a known Iranian cyber espionage group that targets government, energy, and critical infrastructure organizations in the Middle East and beyond.
The malware aims to silently take control of infected systems, gather internal information, execute commands, and exfiltrate data without detection using DNS tunneling techniques.
The attack appeared to impersonate a Jordanian government ministry, suggesting regional government organizations or contractors may have been targeted.
The malware was embedded in an Excel document. When the user enabled macros, it dropped a malicious program that communicates with external servers using hidden DNS queries and responds based on pre-defined program states.
Government and infrastructure organizations often store sensitive information and control critical systems, making them high-value targets for espionage.
Organizations should disable macros by default, monitor DNS traffic for suspicious patterns, and implement strict access controls and endpoint detection solutions.
This appears to be a targeted attack with specific goals, likely focused on espionage. However, the underlying techniques could be reused in broader campaigns.
