RedDelta, a state-sponsored threat actor from China, has been identified as the mastermind behind a complex espionage campaign targeting several countries in Southeast Asia, Mongolia, Taiwan, and beyond. The group's use of PlugX malware and sophisticated attack vectors highlights its focus on governments and diplomatic organizations, as well as its interest in expanding its reach into other regions.
RedDelta, a Chinese state-sponsored threat actor, has been identified as the mastermind behind a complex espionage campaign targeting Southeast Asia, Mongolia, Taiwan, and beyond. The campaign employs PlugX, a highly sophisticated backdoor malware, to infiltrate high-value targets' computer systems. RedDelta uses spear-phishing emails, phishing emails with attachments, and vulnerabilities in legitimate software applications to deliver malicious payloads. The group's attack chain involves DLL side-loading techniques and the use of Cloudflare content delivery networks (CDNs) to proxy C2 traffic. The campaign has targeted government entities, diplomatic organizations, and individuals in multiple countries, including Malaysia, Japan, and India.
RedDelta, a state-sponsored threat actor from China, has been identified as the mastermind behind a complex and sophisticated espionage campaign targeting several countries in Southeast Asia, Mongolia, Taiwan, and beyond. According to recent analysis by Recorded Future's Insikt Group, RedDelta has been actively engaging in cyber espionage activities since at least 2012, employing an array of tactics, techniques, and procedures (TTPs) to infiltrate the computer systems of high-value targets.
At the heart of this campaign is PlugX, a highly sophisticated backdoor malware that allows RedDelta's operatives to gain unauthorized access to targeted networks. The use of PlugX has been observed in several recent campaigns, including those targeting government entities in Southeast Asia and diplomatic organizations in Mongolia and Taiwan.
To deliver these malicious payloads, RedDelta has relied on a range of attack vectors, including spear-phishing emails containing links to HTML files hosted on Microsoft Azure, as well as phishing emails with attachments containing Visual Studio Code tunnels. The group's attack chain typically begins with the exploitation of vulnerabilities in legitimate software applications, such as Windows and Microsoft Office.
Once an initial infection is established, RedDelta's malware payload is deployed using DLL side-loading techniques, which enable the malicious code to execute without the need for a separate executable file. This allows the attackers to maintain a low profile and avoid detection by traditional security solutions.
In recent campaigns, RedDelta has also employed more advanced tactics, including the use of Cloudflare content delivery networks (CDNs) to proxy command-and-control (C2) traffic to its attacker-operated servers. This technique is designed to blend in with legitimate CDN traffic, making it increasingly difficult for security analysts to detect and track the malicious activity.
The Insikt Group's analysis reveals that RedDelta's campaign has targeted several high-value targets, including government entities in Mongolia and Taiwan, as well as diplomatic organizations in Southeast Asia. The group's operatives have also been observed targeting various victims in Malaysia, Japan, the United States, Ethiopia, Brazil, Australia, and India.
To further obscure its activities, RedDelta has registered 10 administrative servers communicating with two known C2 servers, all of which are linked to China Unicom Henan Province. This indicates that the group is leveraging existing infrastructure and services provided by Chinese state-owned enterprises to support its espionage operations.
The deployment of PlugX malware to target Mongolia and Taiwan in espionage campaigns highlights RedDelta's focus on governments and diplomatic organizations in Southeast Asia, as well as its interest in expanding its reach into other regions. The group's historical targeting of groups seen as threats to the Chinese Communist Party's power is consistent with this trend.
In conclusion, RedDelta's sophisticated espionage campaign highlights the evolving nature of state-sponsored threat actors and their willingness to adapt and innovate their tactics to achieve their objectives. As security professionals and policymakers continue to grapple with the challenges posed by these actors, it is essential to stay vigilant and proactive in countering their activities and protecting against future attacks.
