  • Hackers hijack AOMEI update servers to secretly spread malware

    Hackers hijack AOMEI update servers to secretly spread malware

    Between April and July 2026, hackers compromised AOMEI’s servers to distribute malware through its Backupper backup software. The attackers briefly modified configuration files controlling the software’s update and notification systems, then restored them to hide their tracks. Security researchers from ManageEngine, Google, and Mandiant discovered the campaign and attributed it to a threat actor called UNC7017, who used the compromised infrastructure to spread two malware programs: CROSSROAD, a downloader, and SHINYROAD, a backdoor. Organizations in multiple countries across IT services, telecommunications, and higher education sectors were affected.

    The attackers exploited three brief windows when malicious files were distributed, lasting between 5 and 10 minutes each. The CROSSROAD downloader performed reconnaissance and established persistence, while SHINYROAD used legitimate Radmin components to connect to attacker-controlled servers. Researchers also identified attempts to steal Windows authentication hashes. AOMEI stated that its chief technology officer was leading an investigation after the company secured its servers and patched vulnerabilities, though the company did not confirm how attackers gained initial access or whether the compromise was fully resolved.

  • AI-Found Linux Kernel Flaw Gives Local Users Root, and Can Break a Guest Out to the Host

    AI-Found Linux Kernel Flaw Gives Local Users Root, and Can Break a Guest Out to the Host

    A security vulnerability in the Linux kernel’s vhost subsystem, tracked as CVE-2026-74580 and named Vghost, allows local users to gain root access across nearly a decade of kernel versions. In certain virtualization setups, untrusted virtual machines can exploit the flaw to write to the host’s memory and take control of the program running the virtual machine. Tencent Zhuque Lab discovered the flaw and released a fix on August 3, publishing detailed documentation and working demonstrations on October 12. No public evidence of exploitation has emerged.

    The vhost subsystem manages network and input/output acceleration for virtual machines and containers. The vulnerability stems from a cache mechanism that fails to clear when ring configurations change, allowing attackers to access kernel memory without bounds checking. The flaw affects Linux kernels from version 4.11 through 7.2-rc4 and has been confirmed on major distributions. Users should install patched kernels or restrict access to vhost device nodes as a temporary measure. Major Linux distributors including Red Hat, Amazon, and Oracle have released fixes.

  • Microsoft: October Windows Server updates break Exchange sign-in, mail flow

    Microsoft: October Windows Server updates break Exchange sign-in, mail flow

    Microsoft has identified problems with this month’s Windows Server security updates that are disrupting Exchange Server operations. The company confirmed that users on Windows Server 2019 and later versions are experiencing difficulties signing into Outlook on the web and receiving email after installing the October updates. Some affected systems display specific error messages and event logs indicating mailbox access failures.

    Microsoft attributes the issues to a new default memory limit on Endpoint Mapper that restricts simultaneous lookup calls to 512, which proves insufficient during heavy Exchange Server usage. While the company works on a permanent solution, it has released a temporary workaround involving a registry modification that administrators can apply to affected systems. Microsoft clarified that the problems are not caused by Exchange Server security updates themselves and advised customers against uninstalling the Windows Server updates.

  • Unpatched Broadcom Wi-Fi Flaw Lets Attackers in Range Run Code as Root on Routers

    Unpatched Broadcom Wi-Fi Flaw Lets Attackers in Range Run Code as Root on Routers

    A vulnerability in Broadcom’s Wi-Fi setup software allows attackers within radio range to execute code with root privileges on affected routers without needing the network password, according to a disclosure by security researcher Quentin Kaiser on October 16. The flaw affects routers from multiple vendors, with Kaiser demonstrating successful attacks against home gateways supplied by three Belgian internet providers. In some cases, the exploit extracted the Wi-Fi password from the device, while in others it established a remote command shell over the air.

    The vulnerability exists in Broadcom’s Wi-Fi Protected Setup implementation and stems from improper handling of fragmented setup messages, which can corrupt router memory. Millions of devices worldwide are estimated to be affected, including older eCos-based chips that will likely never receive patches. No CVE has been assigned despite Broadcom’s knowledge of the flaw since 2018, and no fixes have been deployed to affected routers. Defenders can use YARA rules and scanning scripts to identify vulnerable equipment, though replacement remains the only option for devices incapable of receiving patches.

  • Scientists tested 39 sweeteners and uncovered surprising gut effects

    Scientists tested 39 sweeteners and uncovered surprising gut effects

    Researchers at the University of Cambridge tested 39 sweeteners against 25 species of gut bacteria in laboratory experiments and found that approximately three-quarters of the sweeteners altered the growth of at least one bacterial species. Some sweeteners slowed or stopped the growth of microbes associated with digestive health. The findings were published in Molecular Systems Biology, though scientists emphasized that these experiments occurred in laboratory settings rather than in human bodies, and further research is needed to determine real-world health implications.

    The study also examined how sweeteners interact with common medications and substances. Researchers discovered over 100 instances where a sweetener’s effect on bacteria changed when combined with other compounds. Notably, the sweetener isosteviol paired with the antidepressant duloxetine strongly suppressed two important gut bacteria involved in digestive health and blood sugar regulation, and altered the diversity of a simulated gut microbiome. The findings challenge the assumption that sweeteners are metabolically neutral and highlight the importance of studying how everyday combinations of ingredients and medications interact within the digestive system.
