## Snapshot Microsoft has observed several notable cyber and influence trends from China and North Korea since June 2023 that demonstrate not only doubling down on familiar targets, but also attempts to use more sophisticated influence techniques to achieve their goals. Chinese cyber actors broadly selected three target areas over the last seven months. - One set of Chinese actors extensively targeted entities across the South Pacific Islands. - A second set of Chinese activity continued a streak of cyberattacks against regional adversaries in the South China Sea region. - Meanwhile, a third set of Chinese actors compromised the US defense industrial base. Chinese influence actors-rather than broadening the geographic scope of their targets-honed their techniques and experimented with new media. Chinese influence campaigns continued to refine AI-generated or AI-enhanced content. The influence actors behind these campaigns have shown a willingness to **both amplify AI-generated media that benefits their strategic narratives, as well as create their own video, memes, and audio content**. Such tactics have been used in campaigns stoking divisions within the United States and exacerbating rifts in the Asia-Pacific region-including Taiwan, Japan, and South Korea. These campaigns achieved varying levels of resonance with no singular formula producing consistent audience engagement. North Korean cyber actors made headlines for **increasing software supply chain attacks and cryptocurrency heists over the past year**. While strategic spear-phishing campaigns targeting researchers who study the Korean Peninsula remained a constant trend, North Korean threat actors appeared to make greater use of legitimate software to compromise even more victims. ## Activity Overview ### Chinese cyber operations target strategic partners and competitors #### Gingham Typhoon targets government, IT, and multinational entities across the South Pacific Islands **** *Figure 1: Observed events from Gingham Typhoon from June 2023 to January 2024 highlights their continued focus on South Pacific Island nations. However, much of this targeting has been ongoing, reflecting a yearslong focus on the region. Geographic locations and diameter of symbology are representational. * During the summer of 2023, Microsoft Threat Intelligence observed extensive activity from China-based espionage group Gingham Typhoon that targeted nearly every South Pacific Island country. Gingham Typhoon is the most active actor in this region, hitting international organizations, government entities, and the IT sector with complex phishing campaigns. Victims also included vocal critics of the Chinese government. Diplomatic allies of China who were victims of recent Gingham Typhoon activity include executive offices in government, trade-related departments, internet service providers, as well as a transportation entity. Heightened geopolitical and diplomatic competition in the region may be motivations for these offensive cyber activities. China pursues strategic partnerships with South Pacific Island nations to expand economic ties and broker diplomatic and security agreements. Chinese cyber espionage in this region also follows economic partners. For example, Chinese actors engaged in large-scale targeting of multinational organizations in Papua New Guinea, a longtime diplomatic partner that is benefiting from multiple Belt and Road Initiative (BRI) projects including the construction of a major highway which links a Papua New Guinea government building to the capital city\'s main road.

Since the initial disclosure of CVE-2023-46805 and CVE-2024-21887 on Jan. 10, 2024, Mandiant has conducted multiple incident response engagements across a range of industry verticals and geographic regions. Mandiant\'s previous blog post, Cutting Edge, Part 3: Investigating Ivanti Connect Secure VPN Exploitation and Persistence Attempts, details zero-day exploitation of CVE-2024-21893 and CVE-2024-21887 by a suspected China-nexus espionage actor that Mandiant tracks as UNC5325. This blog post, as well as our previous reports detailing Ivanti exploitation, help to underscore the different types of activity that Mandiant has observed on vulnerable Ivanti Connect Secure appliances that were unpatched or did not have the appropriate mitigation applied. Mandiant has observed different types of post-exploitation activity across our incident response engagements, including lateral movement supported by the deployment of open-source tooling and custom malware families. In addition, we\'ve seen these suspected China-nexus actors evolve their understanding of Ivanti Connect Secure by abusing appliance-specific functionality to achieve their objectives. As of April 3, 2024, a patch is readily available for every supported version of Ivanti Connect Secure affected by the vulnerabilities. We recommend that customers follow Ivanti\'s latest patching guidance and instructions to prevent further exploitation activity. In addition, Ivanti released a new enhanced external integrity checker tool (ICT) to detect potential attempts of malware persistence across factory resets and system upgrades and other tactics, techniques, and procedures (TTPs) observed in the wild. We also released a remediation and hardening guide |
