ADVISORY SUMMARY Successful exploitation of these vulnerabilities could allow an attacker to write files, access unauthorized information, exhaust memory, or crash affected DCMTK client or server processes. 2. RECOMMENDED PRACTICES CISA recommends users take defensive measures to minimize the...

The vulnerability of the Remote Access SSL VPN microprogramming-based network interface device from Cisco Adaptive Security Appliance (ASA) and Cisco Secure Firewall Threat Defense (FTD) allows a attacker to cause a service outage.

The vulnerability of the Remote Access SSL VPN microprogramming network interface layer software developed by Cisco Adaptive Security Appliance ASA and Cisco Secure Firewall Threat Defense FTD is related to unlimited distribution of resources. Exploiting this vulnerability could allow a malicious...

Security--Fidelity Tradeoffs: The Hidden Cost of Prompt Injection Defense

We identify a security-fidelity tradeoff in defending LLMs against indirect prompt injection: defenses resist injected instructions largely by suppressing untrusted text, which corrupts tasks that must preserve it, such as translation and document editing. Attack-success metrics cannot see this,...

Hephaestus: Toward a Cybersecurity AI Scientist

Cyber offense is moving to machine speed; cyber research itself is not. Existing AI scientist systems make end-to-end research automation increasingly plausible, but they target relatively stable scientific domains. We argue that AI-native cybersecurity is a different kind of scientific object. I...

Wireless Backdoor Attack and Defense for Semantic Communications over Multiple Access Channel

Semantic communication SemCom aims to preserve semantic meaning and task-oriented information beyond conventional message recovery over wireless channels. The adoption of SemCom in shared-access wireless networks introduces new vulnerabilities for multi-user semantic inference. This paper conside...

OpenAI Previews GPT-5.6 Sol With Restricted Access and Stronger Cyber Safeguards

OpenAI on Friday released three versions of GPT-5.6 , called Sol, Terra, and Luna , as a limited preview to a small number of companies as part of an ongoing engagement with the U.S. government. While Sol is the latest flagship model and the most powerful, Terra strikes a balance between efficien...

FlipGuard: Defending Large Language Models against Quantization-Conditioned Backdoor Attacks

Model quantization is essential for the efficient deployment of Large Language Models LLMs, but introduces a critical vulnerability: Quantization-Conditioned Backdoor QCB attacks. In these attacks, malicious behaviors remain dormant in full-precision models and activate only after specific...

LLM Agents Security Duality: A Comprehensive Survey of Self-Security and Empowered Cybersecurity

Large language model LLM agents are rapidly being integrated into real-world systems. Their autonomy and tool-use capabilities generate substantial value while simultaneously expanding the security attack surface. This survey provides a comprehensive overview of the opportunities and challenges o...

Beyond IOCs: AI-enabled threat intelligence

Welcome to this week's Threat Source newsletter. The issue of AI in cybersecurity is often portrayed as a binary choice: either a force multiplier for our adversaries, or a tool bringing professional obsolescence. The reality is more nuanced. While AI certainly brings some advantage to attackers,...
