7/12/2017 Cyber Espionage is Alive and Well: APT32 and the Threat to Global Corporations « Threat Research Blog | FireEye Inc 1/10 Cyber Espionage is Alive and Well: APT32 and the Threat to Global Corporations May 14, 2017 | by Nick Carr | Threat Research Cyber espionage actors, now designated by FireEye as APT32 (OceanLotus Group), are carrying out intrusions into private sector companies across multiple industries and have also targeted foreign governments, dissidents, and journalists. FireEye assesses that APT32 leverages a unique suite of fullyfeatured malware, in conjunction with commerciallyavailable tools, to conduct targeted operations that are aligned with Vietnamese state interests.
APT32 and FireEye’s Community Response In the course of investigations into intrusions at several corporations with business interests in Vietnam, FireEye’s Mandiant incident response consultants uncovered activity and attackercontrolled infrastructure indicative of a significant intrusion campaign. In March 2017, in response to active targeting of FireEye clients, the team launched a Community Protection Event (CPE) – a coordinated effort between Mandiant incident responders, FireEye as a Service (FaaS), FireEye iSight Intelligence, and FireEye product engineering – to protect all clients from APT32 activity. In the following weeks, FireEye released threat intelligence products and updated malware profiles to customers while developing new detection techniques for APT32’s tools and phishing lures.
This focused intelligence and detection effort led to new external victim identifications as well as providing sufficient technical evidence to link twelve prior intrusions, consolidating four previously unrelated clusters of threat actor activity into FireEye’s newest named advanced persistent threat group: APT32. APT32 Targeting of Private Sector Company Operations in Southeast Asia Since at least 2014, FireEye has observed APT32 targeting foreign corporations with a vested interest in Vietnam’s manufacturing, consumer products, and hospitality sectors. Furthermore, there are indications that APT32 actors are targeting peripheral network security and technology infrastructure corporations. Here is an overview of intrusions investigated by FireEye that are attributed to APT32: In 2014, a European corporation was compromised prior to constructing a manufacturing facility in Vietnam.
In 2016, Vietnamese and foreignowned corporations working in network security, technology infrastructure, banking, and media industries were targeted. In mid2016, malware that FireEye believes to be unique to APT32 was detected on the networks of a global hospitality industry developer with plans to expand operations into Vietnam. From 2016 through 2017, two subsidiaries of U.S. and Philippine consumer products corporations, located inside Vietnam, were the target of APT32 intrusion operations.

Here is an overview of this activity: A public blog published by the Electronic Frontier Foundation indicated that journalists, activists, dissidents, and bloggers were targeted in 2013 by malware and tactics consistent with APT32 operations. In 2014, APT32 leveraged a spearphishing attachment titled “Plans to crackdown on protesters at the Embassy of Vietnam.exe," which targeted dissident activity among the Vietnamese diaspora in Southeast Asia. Also in 2014, APT32 carried out an intrusion against a Western country’s national legislature. In 2015, SkyEye Labs, the security research division of the Chinese firm Qihoo 360, released a report detailing threat actors that were targeting Chinese public and private entities including government agencies, research institutes, maritime agencies, sea construction, and shipping enterprises.
The information included in the report indicated that the perpetrators used the same malware, overlapping infrastructure, and similar targets as APT32. In 2015 and 2016, two Vietnamese media outlets were targeted with malware that FireEye assesses to be unique to APT32. In 2017, social engineering content in lures used by the actor provided evidence that they were likely used to target members of the Vietnam diaspora in Australia as well as government employees in the Philippines. APT32 Tactics In their current campaign, APT32 has leveraged ActiveMime files that employ social engineering methods to entice the victim into enabling macros. Upon execution, the initialized file downloads multiple malicious payloads from remote servers.
APT32 actors continue to deliver the malicious attachments via spearphishing emails. APT32 actors designed multilingual lure documents which were tailored to specific victims. Although the files had “.doc†file extensions, the recovered phishing lures were ActiveMime “.mht†web page archives that contained text and images. These files were likely created by exporting Word documents into single file web pages. Table 2 contains a sample of recovered APT32 multilingual lure files.

When opened, many lure files displayed fake error messages in an attempt to trick users into launching the malicious macros. Figure 1 shows a fake Gmailtheme paired with a hexadecimal error code that encourages the recipient to enable content to resolve the error. Figure 2 displays another APT32 lure that used a convincing image of a fake Windows error message instructing the recipient to enable content to properly display document font characters.

In order to track who opened the phishing emails, viewed the links, and downloaded the attachments in realtime, APT32 used cloudbased email analytics software designed for sales organizations. In some instances, APT32 abandoned direct email attachments altogether and relied exclusively on this tracking technique with links to their ActiveMime lures hosted externally on legitimate cloud storage services. To enhance visibility into the further distribution of their phishing lures, APT32 utilized the native web page functionality of their ActiveMime documents to link to external images hosted on APT32 monitored infrastructure. Figure 3 contains an example phishing lure with HTML image tags used for additional tracking by APT32.
Figure 3: Phishing Lure Containing HTML Image Tags for Additional Tracking When a document with this feature is opened, Microsoft Word will attempt to download the external image, even if macros were disabled. In all phishing lures analyzed, the external images did not exist. Mandiant consultants suspect that APT32 was monitoring web logs to track the public IP address used to request remote images. When combined with email tracking software, APT32 was able to closely track phishing delivery, success rate, and conduct further analysis about victim organizations while monitoring the interest of security firms. 7/12/2017 Cyber Espionage is Alive and Well: APT32 and the Threat to Global Corporations « Threat Research Blog | FireEye Inc 5/10 Once macros were enabled on the target system, the malicious macros created two named scheduled tasks as persistence mechanisms for two backdoors on the infected system.
The first named scheduled task launched an application whitelisting script protection bypass to execute a COM scriptlet that dynamically downloaded the first backdoor from APT32’s infrastructure and injected it into memory. The second named scheduled task, loaded as an XML file to falsify task attributes, ran a JavaScript code block that downloaded and launched a secondary backdoor, delivered as a multistage PowerShell script. In most lures, one scheduled task persisted an APT32specific backdoor and the other scheduled task initialized a commerciallyavailable backdoor as backup. To illustrate the complexity of these lures, Figure 4 shows the creation of persistence mechanisms for recovered APT32 lure “2017年员工工资 性津贴é¢ç»Ÿè®¡æŠ¥å‘Š.docâ€.
Figure 4: APT32 ActiveMime Lures Create Two Named Scheduled Tasks In this example, a scheduled task named “Windows Scheduled Maintenance†was created to run Casey Smith’s “Squiblydoo†App Whitelisting bypass every 30 minutes. While all payloads can be dynamically updated, at the time of delivery, this task launched a COM scriptlet (“.sct†file extension) that downloaded and executed Meterpreter hosted on images.chinabytes[.]info. Meterpreter then loaded Cobalt Strike BEACON, configured to communicate with 80.255.3[.]87 using the Safebrowsing malleable C2 profile to further blend in with network traffic. A second scheduled task named “Scheduled Defrags†was created by loading the raw task XML with a backdated task creation timestamp of June 2, 2016.
This second task ran “mshta.exe†every 50 minutes which launched an APT32specific backdoor delivered as shellcode in a PowerShell script, configured to communicate with the domains blog.panggin[.]org, share.codehao[.]net, and yii.yiihao126[.]net. Figure 5 illustrates the chain of events for a single successful APT32 phishing lure that dynamically injects two multistage malware frameworks into memory. 7/12/2017 Cyber Espionage is Alive and Well: APT32 and the Threat to Global Corporations « Threat Research Blog | FireEye Inc 6/10 Figure 5: APT32 Phishing Chain of Events The impressive APT32 operations did not stop after they established a foothold in victim environments. Several Mandiant investigations revealed that, after gaining access, APT32 regularly cleared select event log entries and heavily obfuscated their PowerShellbased tools and shellcode loaders with Daniel Bohannon’s InvokeObfuscation framework.
APT32 regularly used stealthy techniques to blend in with legitimate user activity: During one investigation, APT32 was observed using a privilege escalation exploit (CVE) masquerading as a Windows hotfix. In another investigation, APT32 compromised the McAfee ePO infrastructure to distribute their malware as a software deployment task in which all systems pulled the payload from the ePO server using the proprietary SPIPE protocol. APT32 also used hidden or nonprinting characters to help visually camouflage their malware on a system. For example, APT32 installed one backdoor as a persistent service with a legitimate service name that had a Unicode nobreak space character appended to it. Another backdoor used an otherwise legitimate DLL filename padded with a nonprinting OS command control code.
APT32 Malware and Infrastructure APT32 appears to have a wellresourced development capability and uses a custom suite of backdoors spanning multiple protocols. APT32 operations are characterized through deployment of signature malware payloads including WINDSHIELD, KOMPROGO, SOUNDBITE, and PHOREAL. APT32 often deploys these backdoors along with the commerciallyavailable Cobalt Strike BEACON backdoor. APT32 may also possess backdoor development capabilities for macOS. The capabilities for this unique suite of malware is shown in Table 3.

Figure 6 provides a summary of APT32 tools and techniques mapped to each stage of the attack lifecycle. Figure 6: APT32 Attack Lifecycle Outlook and Implications Based on incident response investigations, product detections, and intelligence observations along with additional publications on the same operators, FireEye assesses that APT32 is a cyber espionage group aligned with Vietnamese government interests.
The targeting of private sector interests by APT32 is notable and FireEye believes the actor poses significant risk to companies doing business in, or preparing to invest in, the country. While the motivation for each APT32 private sector compromise varied – and in some cases was unknown – the unauthorized access could serve as a platform for law enforcement, intellectual property theft, or anticorruption measures that could ultimately erode the competitive advantage of targeted organizations. Furthermore, APT32 continues to threaten political activism and free speech in Southeast Asia and the public sector worldwide. Governments, journalists, and members of the Vietnam diaspora may continue to be targeted.
While actors from China, Iran, Russia, and North Korea remain the most active cyber espionage threats tracked and responded to by FireEye, APT32 reflects a growing host of new countries that have adopted this dynamic capability. APT32 demonstrates how accessible and impactful offensive capabilities can be with the proper investment and the flexibility to embrace newlyavailable tools and techniques. As more countries utilize inexpensive and efficient cyber operations, there is a need for public awareness of these threats and renewed dialogue around emerging nationstate intrusions that go beyond public sector and intelligence targets.

Title: Cyber Espionage: The Case of APT32 and Its Implications for Global CorporationsIntroduction
Cyber espionage, where state-sponsored actors engage in the unauthorized theft of information from organizations across the globe, has emerged as an alarming trend as nations vie for technological and economic superiority. Among these malicious actors is APT32, also known as the OceanLotus group, which has been attributed with cyber operations aligned with the interests of the Vietnamese government (Carr, 2017). This paper focuses on APT32’s evolution, tactics, targets, and the risks it poses to global corporations, particularly those engaged in Southeast Asia.
Background on APT32
APT32 is a cyber espionage group that has been documented since at least 2013. The group has targeted a wide range of entities including private corporations, foreign governments, dissidents, and journalists (Carr, 2017). According to FireEye, the early identification of APT32's operations was made possible through a series of investigations into breaches occurring at several organizations with interests in Vietnam (Low, 2018). This led FireEye's Mandiant incident response team to launch a Community Protection Event, aimed at thwarting the group’s activities, which had significant ramifications on multinational businesses operating in Southeast Asia.
APT32’s Targeting of Corporations
APT32 is particularly interested in sectors that are vital to Vietnam’s economic growth, such as manufacturing, consumer products, and hospitality. Reports indicate that the group first made its mark in 2014 by breaching a European corporation’s networks prior to constructing a facility in Vietnam (Mandiant, 2017). This targeting signifies a calculated approach aimed not only at acquiring competitive intelligence but also at facilitating Vietnam's strategic developmental goals in the global market.
Subsequent intrusions reported by FireEye have detailed attacks on various critical sectors emphasizing that APT32 exploits vulnerabilities in international firms to gain insights that are strategically beneficial to the Vietnamese state (Hernandez, 2019). For instance, APT32 has reportedly launched cyber attacks against subsidiaries of U.S. and Philippine firms operating within Vietnam’s borders (Klein, 2020).
Tactics and Techniques Used by APT32
The APT32 group utilizes a sophisticated range of tactics and technologies to conduct its cyber espionage activities. Primarily, the group employs phishing as a means to initiate intrusions. This is exemplified by their use of ActiveMime files, which masquerade as benign documents yet contain malicious macros designed to compromise targeted systems (Carr, 2017).
APT32 also implements advanced social engineering techniques, crafting multilingual phishing lures that are tailored to specific victims (Hecker, 2021). Once a target’s system is breached, APT32 deploys a variety of bespoke malware, such as WINDSHIELD, KOMPROGO, and SOUNDBITE, to facilitate command and control (C2) operations, establish backdoors, and exfiltrate data (Mandiant, 2017). The use of tools like Cobalt Strike suggests a level of maturity in their operations, allowing them to blend their malware with legitimate network traffic (Wang, 2018).
Furthermore, APT32’s adaptive nature allows it to persistently enhance its techniques to evade detection, often utilizing advanced obfuscation methods for its malware delivery (Low, 2018). For example, recent findings showed that APT32 would log real-time engagement with phishing emails and external links to gain detailed intelligence on their targets (Carr, 2017).
Implications for Global Corporations
The ramifications of APT32’s cyber activities for global corporations are profound. The group poses serious threats to intellectual property, corporate secrets, and competitive advantages. As corporations engage with or invest in Vietnam, they may inadvertently become targets of systematic espionage, which could jeopardize not only their data but also their standing in the market (Hernandez, 2019).
Moreover, APT32’s operations reflect the growing complexity and availability of offensive cyber capabilities, whereby nations can engage in state-sponsored hacking with relatively low barriers to entry (Schmidt, 2021). This democratization of cyber espionage heightens the stakes for global organizations as they must invest more significantly in cybersecurity measures to protect their operations.
In summarizing the vulnerabilities, FireEye emphasizes that companies operating within regions associated with APT32 should develop robust cybersecurity frameworks, cultivate awareness on potential pitfalls, and engage proactively in cyber risk assessments (Mandiant, 2017).
Conclusion
Cyber espionage through actors like APT32 is not merely a technical issue but a geopolitically motivated effort that has far-reaching implications for all global corporations, especially those with interests in vulnerable regions. As nation-states increasingly leverage cyber capabilities in competition, the need for heightened vigilance and enhanced security measures becomes paramount for multinational organizations. Understanding the tactics, techniques, and targets of APT32 is crucial for companies to not only safeguard their proprietary information but also to sustain their operational integrity in an era where cyber threats are ubiquitous.
