RealSecu Co., Ltd.To counter threats like the AI-driven phishing and impersonation attacks covered on this page, RealSecu continues joint research with HJITM on AI-based threat detection and anomaly analysis.

Today's trendAI is weaponized—from model‑extraction leaks and deep‑fake videos to autonomous hacking agents—creating attack vectors that endanger privacy, supply chains and cyber expertise. Defences: Dell flags supply‑chain risks; ISC² launches a Cyber‑AI Workforce Coalition and a pilot AI security certification.

Vulnerabilities & Jailbreaks

OpenAI Compaction Flaw Allows Researchers to Extract Hidden Reasoning

Original headline: OpenAI Compaction Flaw Let Researchers Bypass Hidden Reasoning Protections

Security firm Xint demonstrated that a flaw in OpenAI’s compaction feature can be leveraged to copy a model’s hidden reasoning in plain text. The compaction function, which compresses long conversations to save space, normally returns encrypted reasoning that users cannot read, but the exploit bypasses this protection.

Exposure of hidden reasoning could undermine defenses against prompt injection and jailbreak attacks.
