China-Linked Hackers Step Up Quiet Spying Across South-East Asia Threat actors linked to China have been blamed for a new wave of cyber-espionage campaigns targeting government and law-enforcement agencies across South-East Asia during 2025, according several media reports. Researchers at Check Point Research said they are tracking a previously undocumented cluster, which they have named Amaranth-Dragon, that has targeted Cambodia, Thailand, Laos, Indonesia, Singapore and the Philippines.  The activity shows technical and operational links to APT41, a well-known Chinese hacking ecosystem.  “Many of the campaigns were timed to coincide with sensitive local political developments, official government decisions, or regional security events,” Check Point said. “By anchoring malicious activity in familiar, timely contexts, the attackers significantly increased the likelihood that targets would engage with the content.”  The firm described the operations as tightly scoped and deliberately restrained, suggesting an effort to establish long-term access rather than cause disruption. Infrastructure was configured to communicate only with victims in specific countries, reducing the risk of discovery.  A key technique involved exploiting CVE-2025-8088, a now-patched flaw in WinRAR that allows arbitrary code execution when a malicious archive is opened. Check Point said the group began exploiting the vulnerability within days of its public disclosure in August. “The speed and confidence with which this vulnerability was operationalised underscores the group’s technical maturity and preparedness,” the researchers said.  Although the initial infection vector remains unclear, analysts believe spear-phishing emails were used to distribute malicious RAR files hosted on cloud services such as Dropbox. Once opened, the archive launches a loader using DLL side-loading, a tactic frequently associated with Chinese groups. The loader then retrieves an encryption key from one server, decrypts a payload from another location and executes it directly in memory.  The final stage deploys Havoc, an open-source command-and-control framework. Earlier versions of the campaign relied on ZIP files containing Windows shortcuts and batch files, while a separate operation in Indonesia delivered a custom remote-access trojan known as TGAmaranth RAT. That malware used a hard-coded Telegram bot for command and control and supported functions such as taking screenshots, running shell commands and transferring files.  Check Point said the command infrastructure was shielded by Cloudflare and restricted by geography, accepting traffic only from targeted countries. Compilation times and working patterns pointed to operators based in China’s time zone.  “In addition, the development style closely mirrors established APT41 practices,” the company said, adding that overlaps in tools and techniques suggest shared resources within the ecosystem. The findings come as another Chinese group, Mustang Panda, was linked to a separate espionage campaign uncovered by Dream Research Labs. The operation, dubbed PlugX Diplomacy, targeted officials involved in diplomacy, elections and international coordination between December 2025 and mid-January 2026.   “Rather than exploiting software vulnerabilities, the operation relied on impersonation and trust,” Dream said.  Victims were lured into opening files disguised as diplomatic or policy documents, which triggered infection automatically. The files installed a modified version of PlugX, a long-used Chinese espionage tool, through a multi-step process involving Windows shortcuts, PowerShell scripts and DLL search-order hijacking using a legitimate signed executable. A decoy document was shown to victims while the malware quietly embedded itself in the system.  “The correlation between actual diplomatic events and the timing of detected lures suggests that analogous campaigns are likely to persist as geopolitical developments unfold,” Dream concluded.

Chinese Hackers Attack Prominent U.S Organizations Chinese cyber-espionage groups attacked U.S organizations with links to international agencies. This has now become a problem for the U.S, as state-actors from China keep attacking.  Attackers were trying to build a steady presence inside the target network. Series of attacks against the U.S organizations  Earlier this year, the breach was against a famous U.S non-profit working in advocacy, that demonstrated advanced techniques and shared tools among Chinese cyber criminal gangs like APT41, Space Pirates, and Kelp. They struck again in April with various malicious prompts checking both internal network breach and internet connectivity, particularly targeting a system at 192.0.0.88. Various tactics and protocols were used, showing both determination and technical adaptability to get particular internal resources. Attack tactics  Following the connectivity tests, the hackers used tools like netstat for network surveillance and made an automatic task via the Windows command-line tools. This task ran a genuine MSBuild.exe app that processed an outbound.xml file to deploy code into csc.exe and connected it to a C2 server.  These steps hint towards automation (through scheduled tasks) and persistence via system-level privileges increasing the complexity of the compromise and potential damage. Espionage methods  The techniques and toolkit show traces of various Chinese espionage groups. The hackers weaponized genuine software elements. This is called DLL sideloading by abusing vetysafe.exe (a VipreAV component signed by Sunbelt Software, Inc.) to load a malicious payload called sbamres.dll. This tactic was earlier found in campaigns lkmkedytl Earth Longzhi and Space Pirates, the former also known as APT41 subgroup. Coincidentally, the same tactic was found in cases connected to Kelp, showing the intrusive tool-sharing tactics within Chinese APTs.

APT41 Exploits Google Calendar in Stealthy Cyberattack; Google Shuts It Down   Chinese state-backed threat actor APT41 has been discovered leveraging Google Calendar as a command-and-control (C2) channel in a sophisticated cyber campaign, according to Google’s Threat Intelligence Group (TIG). The team has since dismantled the infrastructure and implemented defenses to block similar future exploits. The campaign began with a previously breached government website — though TIG didn’t disclose how it was compromised — which hosted a ZIP archive. This file was distributed to targets via phishing emails. Once downloaded, the archive revealed three components: an executable file and a dynamic-link library (DLL) disguised as image files, and a Windows shortcut (LNK) masquerading as a PDF. When users attempted to open the phony PDF, the shortcut activated the DLL, which then decrypted and launched a third file containing the actual malware, dubbed ToughProgress. Upon execution, ToughProgress connected to Google Calendar to retrieve its instructions, embedded within event descriptions or hidden calendar events. The malware then exfiltrated stolen data by creating a zero-minute calendar event on May 30, embedding the encrypted information within the event's description field. Google noted that the malware’s stealth — avoiding traditional file installation and using a legitimate Google service for communication — made it difficult for many security tools to detect. To mitigate the threat, TIG crafted specific detection signatures, disabled the threat actor’s associated Workspace accounts and calendar entries, updated file recognition tools, and expanded its Safe Browsing blocklist to include malicious domains and URLs linked to the attack. Several organizations were reportedly targeted. “In partnership with Mandiant Consulting, GTIG notified the compromised organizations,” Google stated. “We provided the notified organizations with a sample of TOUGHPROGRESS network traffic logs, and information about the threat actor, to aid with detection and incident response.” Google did not disclose the exact number of impacted entities.
