This is your Digital Dragon Watch: Weekly China Cyber Alert podcast.
Hey there, cyber guardians! Ting here, dropping your Digital Dragon Watch update for May 27th, 2025. Grab your coffee and buckle up—it's been a wild week in the China cyber scene!
First up, we've got UNC5221 hackers exploiting fresh Ivanti EPMM vulnerabilities since May 15th. They've been leveraging two critical flaws—CVE-2025-4427 and CVE-2025-4428—to gain remote access and steal data from global enterprises. Classic move, but effective. If you're running Ivanti EPMM, you need to patch yesterday!
But that's not all—EclecticIQ dropped a bombshell report on May 14th about Chinese state-backed actors targeting critical infrastructure worldwide through SAP NetWeaver Visual Composer. They're exploiting CVE-2025-31324, an unauthenticated file upload vulnerability that gives them remote code execution capabilities. Analyst Arda Büyükkaya caught them red-handed with an exposed directory at IP 15.204.56.106 that documented their intrusions. The campaign has been linked to several known groups including UNC5221, UNC5174, and CL-STA-0048.
Meanwhile, geopolitical tensions are heating up! Just today, mainland China accused Taiwan of orchestrating cyberattacks against approximately 1,000 sensitive networks across 10+ provinces. According to Guangzhou police, who made the announcement on May 20th, a hacker group allegedly backed by Taiwan's Democratic Progressive Party (DPP) targeted military-industrial assets, power grids, water infrastructure, transportation systems, and government networks. The Tianhe district Public Security Bureau claims the attackers used phishing emails, vulnerability exploitation, brute-force password attacks, and Trojan horses—launching operations from IPs in the US, France, and Japan.
On the regulatory front, China continues to strengthen its cybersecurity framework. The latest draft amendments to China's Cybersecurity Law introduce stricter penalties and clearer enforcement mechanisms, aligning more closely with existing data protection regulations.
My recommendation? If you're managing critical infrastructure or enterprise systems, prioritize patching those Ivanti and SAP vulnerabilities immediately. Implement robust email filtering to catch phishing attempts, and strengthen authentication protocols to prevent brute-force attacks.
Stay vigilant, stay patched, and remember—in the cyber realm, dragons don't sleep! This is Ting, signing off until next week's Digital Dragon Watch. Keep your firewalls hot and your coffee hotter!
