A new tool is revealing the invisible networks inside cancer

Spanish researchers have created a powerful new open-source tool that helps uncover the hidden genetic networks driving cancer. Called RNACOREX, the software can analyze thousands of molecular interactions at once, revealing how genes communicate inside tumors and how those signals relate to patient survival. Tested across 13 different cancer types using international data, the tool matches the predictive power of advanced AI systems—while offering something rare in modern analytics: clear, interpretable explanations that help scientists understand why tumors behave the way they do.

Week in review: Exploited zero-day in Cisco email security appliances, Kali Linux 2025.4 released

Here’s an overview of some of last week’s most interesting news, articles, interviews and videos: How researchers are teaching AI agents to ask for permission the right way People are starting to hand more decisions to AI agents, from booking trips to sorting digital files. The idea sounds simple. Tell the agent what you want, then let it work through the steps. The hard part is what the agent does with personal data along the … More → The post Week in review: Exploited zero-day in Cisco email security appliances, Kali Linux 2025.4 released appeared first on Help Net Security.

The 98% mystery: Scientists just cracked the code on “junk DNA” linked to Alzheimer’s

Researchers have revealed that so-called “junk DNA” contains powerful switches that help control brain cells linked to Alzheimer’s disease. By experimentally testing nearly 1,000 DNA switches in human astrocytes, scientists identified around 150 that truly influence gene activity—many tied to known Alzheimer’s risk genes. The findings help explain why many disease-linked genetic changes sit outside genes themselves. The resulting dataset is now being used to train AI systems to predict gene control more accurately.

Dismantling Defenses: Trump 2.0 Cyber Year in Review

The Trump administration has pursued a staggering range of policy pivots this past year that threaten to weaken the nation’s ability and willingness to address a broad spectrum of technology challenges, from cybersecurity and privacy to countering disinformation, fraud and corruption. These shifts, along with the president’s efforts to restrict free speech and freedom of the press, have come at such a rapid clip that many readers probably aren’t even aware of them all.

AI isn’t one system, and your threat model shouldn’t be either

In this Help Net Security interview, Naor Penso, CISO at Cerebras Systems, explains how to threat model modern AI stacks without treating them as a single risk. He discusses why partitioning AI systems by function and impact matters, how to frame threat modeling for business leaders, and which assumptions break down as AI becomes core infrastructure. What’s the right way to partition a modern AI stack for threat modeling so teams avoid lumping everything under … More → The post AI isn’t one system, and your threat model shouldn’t be either appeared first on Help Net Security.

LLMs work better together in smart contract audits

Smart contract bugs continue to drain real money from blockchain systems, even after years of tooling and research. A new academic study suggests that large language models can spot more of those flaws when they work in coordinated groups instead of alone. Researchers at Georgia Tech have developed a framework called LLMBugScanner that combines fine tuned language models with ensemble voting to detect vulnerabilities in Ethereum smart contracts. The research evaluates whether pairing domain specific … More → The post LLMs work better together in smart contract audits appeared first on Help Net Security.
