MASSIVE CHINA-LINKED SMISHING CAMPAIGN LEVERAGED 194,000 DOMAINS

An extensive SMS phishing campaign, attributed to a Chinese-speaking group called Smishing Triad, has used over 194,000 domains since early 2024. The attackers impersonated services such as banks and delivery firms to steal personal data via urgent texts. Their tactics include cycling through disposable domains and running a phishing-as-a-service operation, making detection challenging for authorities worldwide.

WESTERN SYDNEY UNI SUFFERS DATA BREACH, AGAIN

Western Sydney University (WSU) reported its third security incident of the year, with an unauthorized user accessing data belonging to staff and students. The breached data includes tax file numbers, bank account details, passport and driver's license details, visa information, health and disability information, addresses, email addresses, phone numbers, names, dates of birth, ethnicities, and student and staff IDs. WSU stated that the breach was caused by a daisy chain of supply chain attacks culminating in a third-party student management system being breached.

MAKING A VIRTUAL MACHINE LOOK LIKE REAL HARDWARE TO MALWARE

Malware can easily detect VirtualBox environments through obvious indicators such as registry keys, file artifacts, MAC addresses, and VirtualBox-specific naming conventions, undermining VM-based malware analysis. Security researchers created vbox_stealth (Bash) and VBoxCloak (PowerShell) tools to mask VM indicators by renaming hardware identifiers, modifying registry entries, and removing VirtualBox-specific processes and files. While these tools improve VM stealth capabilities, sophisticated malware may still employ more subtle detection methods that remain difficult to circumvent.

ECS ON EC2: COVERING GAPS IN IMDS HARDENING

When launching AWS ECS tasks on EC2 instances, each task, by default, has access to the Instance Metadata Service (IMDS), which can be used to access credentials of other tasks or to escalate privileges to the instance role. Using IMDSv2 with a hop limit of 1 is not effective for stopping this attack vector, as some networking modes can still access IMDS. The article includes details for blocking IMDS access in each networking mode.

AI BROWSERS FACE A SECURITY FLAW AS INEVITABLE AS DEATH AND TAXES

Prompt injection is an increasingly critical security issue as AI-driven browsers gain agentic capabilities: they can now act on users' behalf, from opening web pages to handling emails and files. This opens up new attack vectors, such as direct injection via URLs or indirect injection hidden within website or document text, allowing attackers to trick bots into performing dangerous actions without user consent. While some countermeasures, such as reduced privileges and human oversight, can lower risks, experts believe prompt injection is unavoidable, not just a bug but a fundamental vulnerability whenever AI interprets untrusted data.

TOOLSHELL USED TO COMPROMISE TELECOMS COMPANY IN MIDDLE EAST

Chinese threat actors exploited the ToolShell SharePoint vulnerability (CVE-2025-53770) just two days after Microsoft patched it in July, compromising a Middle East telecoms company and multiple government agencies by using the Zingdoor backdoor, the ShadowPad Trojan, and KrustyLoader malware. The attackers demonstrated rapid exploitation capabilities by mass-scanning for vulnerable systems, then deploying sophisticated toolsets, including DLL sideloading techniques, credential-dumping utilities, and the Sliver C2 framework for persistent access. Organizations should prioritize immediate patching of SharePoint servers and monitor for indicators, including the provided file hashes, with particular focus on DLL sideloading activities and connections to the identified AWS-hosted C2 infrastructure.
