How do cyber operations from groups in Iran and Vietnam compare in tactics and targets?
While both Iranian and Vietnamese cyber groups engage in state-sponsored cyber operations, their primary motivations, geopolitical contexts, and consequently, their tactics and targets, differ significantly.
Iranian Cyber Groups (e.g., APT33/Elfin, APT34/OilRig, APT35/Charming Kitten, MuddyWater)
Main Motives:
Iran's cyber activities are strongly driven by its geopolitical aspirations, regional rivalries (especially with Saudi Arabia and Israel), and desire to counter international sanctions. Their motivations include:
Espionage: Gathering intelligence on political, military, and economic developments, particularly in the Middle East, U.S., Europe, and Israel.
Disruption and Retaliation: Disrupting critical infrastructure, especially against perceived adversaries (e.g., in response to sanctions or political actions). They are willing to engage in destructive attacks.
Influence Operations: Spreading propaganda, manipulating public opinion, and sowing discord in rival nations.
Intellectual Property Theft (Secondary): While they do engage in this, it's often more opportunistic or tied to specific military/dual-use technologies rather than broad economic development.
Internal Control: Surveillance and repression of dissidents, both domestically and abroad.
Tactics:
Iranian groups often leverage a blend of technical sophistication and social engineering.
Aggressive Spear-Phishing & Social Engineering: Highly sophisticated and persistent phishing campaigns are a hallmark. They often impersonate legitimate entities (journalists, academics, government officials, recruiters) to build trust and trick targets into revealing credentials or downloading malware. They're known for using compromised accounts for further phishing.
Exploitation of Known Vulnerabilities: They are quick to exploit newly disclosed vulnerabilities (N-days) in widely used software and internet-facing systems (VPNs, firewalls, Exchange servers) to gain initial access.
Living Off The Land (LotL) & OSINT: They frequently use legitimate system tools (PowerShell, RDP, Mimikatz) and open-source intelligence (OSINT) to evade detection and understand victim networks.
Web Shells & Backdoors: Deployment of web shells for persistent access and custom backdoors.
Destructive Malware/Wipers: Iranian groups have a history of deploying destructive malware (e.g., Shamoon, ZeroCleare) to wipe data and disable systems, particularly against targets in the energy and industrial sectors.
Hybrid Operations: Increasingly, they combine hacking and data theft with information operations, leaking stolen data online, and using social media for amplification and harassment.
Ransomware (Collaborative/Opportunistic): While not their primary goal like North Korea, some Iranian groups have been observed collaborating with cybercriminal ransomware affiliates or directly deploying ransomware for financial gain or disruption.
Targets:
Middle East Region: Heavily focused on Gulf Cooperation Council (GCC) countries (especially Saudi Arabia, UAE), Israel, and other regional rivals.
Government & Military: Foreign ministries, defense contractors, intelligence agencies, and government officials, particularly those involved in nuclear policy, sanctions, or regional security.
Energy Sector (Oil & Gas): A long-standing target for both espionage and potential disruption, reflecting Iran's strategic interests.
Critical Infrastructure (OT/ICS): Increasing focus on industrial control systems and operational technology, potentially for pre-positioning or disruptive attacks.
Telecommunications & Financial Services: For intelligence gathering and network access.
Journalists, Academics, Dissidents, Human Rights Activists: Both within Iran and among the diaspora, for surveillance and repression.
Vietnamese Cyber Groups (e.g., APT32/OceanLotus, APT30/Naikon)
Main Motives:
Vietnamese cyber operations are strongly linked to national economic development, protecting sovereignty claims (especially in the South China Sea), and maintaining political stability.
Economic Espionage: Stealing intellectual property, trade secrets, and competitive intelligence to support Vietnamese industries and accelerate economic growth. This is a very significant motivation.
Political Espionage: Gathering intelligence on foreign governments, political organizations, and diplomats relevant to Vietnam's geopolitical interests, particularly concerning regional rivals and partners.
Surveillance and Monitoring: Tracking and monitoring political dissidents, journalists, NGOs, and foreign entities perceived as a threat to the ruling party or national stability.
South China Sea Disputes: Gaining intelligence on rival claimants and international actors involved in the South China Sea disputes.
Tactics:
Vietnamese groups often demonstrate high levels of sophistication and persistence, with a focus on long-term access and stealth.
Sophisticated Spear-Phishing: Highly customized and contextualized spear-phishing emails, often impersonating trusted contacts or organizations, are a primary initial access vector.
Watering Hole Attacks: Compromising websites frequented by specific targets and implanting malware to infect visitors.
Custom Malware and Backdoors: Development and use of sophisticated custom malware (Remote Access Trojans, info-stealers) designed for covert data exfiltration and persistent access.
Exploitation of Zero-Day and N-Day Vulnerabilities: While less frequent than Iranian groups' aggressive N-day exploitation, they are capable of exploiting zero-days.
Supply Chain Attacks: There have been instances where Vietnamese groups have targeted software or hardware vendors to compromise their clients downstream.
Leveraging Cloud Services: Using legitimate cloud services for command and control (C2) or data exfiltration to blend in with normal network traffic.
Evasion Techniques: Employing various techniques to avoid detection by security software, including code obfuscation and anti-analysis checks.
Targets:
Southeast Asian Governments: Particularly those involved in the South China Sea disputes, for political intelligence.
Foreign Businesses & Multinational Corporations: Across various sectors (e.g., automotive, media, hospitality, manufacturing, technology, healthcare, e-commerce) for economic espionage and IP theft.
Political Dissidents & Human Rights Activists: Both domestic and international, for surveillance and control.
Journalists and NGOs: Especially those reporting on Vietnam or human rights issues.
Critical Infrastructure (Limited Public Reporting): While less publicly highlighted than Iranian or Chinese groups, there have been some reports of Vietnamese groups targeting critical infrastructure, but often for intelligence gathering rather than overt disruption.
Comparison Summary:
Feature- Iranian Cyber Groups----
Primary Motive- Geopolitical influence, regional rivalries, countering sanctions, disruption, espionage, retaliation.
Willingness for Disruption- High – known for destructive attacks/wipers.
Key Regions of Focus- Middle East (GCC, Israel), U.S., Europe.
Tactics Emphasis- Aggressive spear-phishing, N-day exploitation, LotL, web shells, destructive malware, information operations.
Financial Crime- Opportunistic ransomware or collaboration with criminals.
Vietnamese Cyber Groups-
Primary Motive-
Economic development (IP theft), political espionage (Sovereignty, South China Sea), internal control.
Willingness for Disruption-
Lower – focus on stealth, long-term access, and data exfiltration, less on overt disruption.
Key Regions of Focus-
Southeast Asia (ASEAN), U.S. (related to economic/political ties).
Tactics Emphasis-
Sophisticated spear-phishing, custom malware, watering holes, supply chain (less common), long-term stealth, cloud usage.
Financial Crime-Less prominent, but some engagement in cybercrime for revenue.
Export to Sheets-
In essence, Iranian groups are more overt and willing to engage in destructive actions driven by immediate geopolitical tensions, while Vietnamese groups are generally more focused on stealthy, long-term espionage and IP theft to support national development and strategic interests in their region.
