Cyberattacks targeting industrial systems are becoming increasingly common and are now striking strategic points within the production chain. The Delta DIALink case reinforces the importance of regular updates and strict access controls on OT devices as essential defensive measures for industrial cybersecurity.
Samsung has released the September 2025 security update to patch a high-severity zero-day vulnerability, CVE-2025-21043 (CVSS 8.8). The flaw, an out-of-bounds write in the libimagecodec.quram.so image-processing library, allows remote attackers to execute arbitrary code without user interaction—similar to zero-click attacks. The vulnerability has already been exploited in the wild, likely through malicious image files sent via WhatsApp or other messaging applications.
