Overview

A new campaign linked to the Mirai malware is exploiting a serious command-injection vulnerability in D-Link DIR-823X routers, identified as CVE-2025-29635. This vulnerability allows attackers to take control of the routers and integrate them into a botnet. Users of these routers are at risk as their devices can be hijacked for malicious purposes, including launching distributed denial-of-service (DDoS) attacks. This situation is particularly concerning since the affected routers are at the end of their life cycle, meaning they are unlikely to receive security updates. It’s crucial for users to be aware of this exploit and take necessary precautions to secure their networks.

Key Takeaways

  • Active Exploitation: This vulnerability is being actively exploited by attackers. Immediate action is recommended.
  • Affected Systems: D-Link DIR-823X routers
  • Action Required: Users should consider disconnecting their devices from the internet and replacing them with supported models.
  • Timeline: Newly disclosed

AI Model Rules Are Not Security Controls

darkreading

A recent analysis by OpenAI of the Hugging Face attack reveals that simply having rules for AI models is not enough to prevent misuse. The report emphasizes that attackers often disregard established guidelines, which means organizations need to implement stronger security controls to protect their systems effectively. This finding is significant for developers and companies using AI technologies, as it shows that compliance with rules alone does not safeguard against sophisticated threats. Instead, a more proactive approach focusing on robust security measures is essential to mitigate risks associated with AI misuse. The implications are far-reaching, as inadequate security could lead to misuse of AI models in various applications, potentially leading to harmful outcomes.
