Fast Facts 1. Global cyber threats like phishing, malware, and deepfakes persist, but India’s threat detections decreased by 12% in 2025, indicating improved awareness and prevention efforts. 2. Ransomware attacks surged by 70% in India from late 2024 to mid-2025, with AI making threat tactics more effective and attack detection more complex. 3. Increasing AI-driven threats blur the line between real and fake videos, especially targeting unpatched edge systems and appliances with zero-day vulnerabilities. 4. Organizations need to partner with advanced cybersecurity vendors for threat intelligence and remain vigilant to evolving risks, particularly in high-stakes sectors like BFSI, mining, and…
Quick Takeaways Microsoft’s latest Patch Tuesday fixes 83 vulnerabilities across its enterprise software, with no actively exploited zero-day bugs for the first time in six months. Over half of the vulnerabilities allow privilege escalation, and six are rated as more likely to be exploited, indicating ongoing targeted risks. Two publicly known vulnerabilities (CVE-2026-21262 and CVE-2026-26127) pose less threat, described as “more bark than bite,” while others could enable arbitrary code execution, especially in Office applications. A notable information-disclosure flaw in Excel (CVE-2026-26144) could be exploited for zero-click data exfiltration, underscoring the importance of applying updates promptly to prevent widespread attacks.…
Fast Facts OpenAI has acquired Promptfoo, a cybersecurity platform that helps enterprises identify and fix vulnerabilities in AI during development, aiming to prevent threats like prompt injection and jailbreaks before deployment. The integration of Promptfoo’s technology into OpenAI Frontier will enable automated security testing, red-teaming, and compliance monitoring, embedding security into the AI development workflow. Promptfoo’s tools are trusted by over 25% of Fortune 500 companies and include open-source resources for evaluating and red-teaming large language models, with ongoing development by OpenAI. This move strengthens enterprise AI security by providing systemic risk detection, proactive mitigation, and comprehensive oversight, addressing critical…
Fast Facts Cybersecurity remains an open-loop system, detecting issues without ensuring systems stay in a trusted, known-good state. This reactive approach causes security teams to focus on symptoms rather than proactively preventing security breaches. Integrating integrity assurance with Secure Access Service Edge (SASE) offers a comprehensive solution to close the security loop. Combining Zero Trust, C2C (Cloud-to-Cloud), and ransomware defenses with integrity guarantees enables organizations to achieve closed-loop security and prevent attacks more effectively. The Issue The story explains that cybersecurity currently faces a significant issue: it functions as an open-loop system. This means that although tools can detect alerts,…
Fast Facts The majority of cloud security incidents (47.1%) are caused by weak or missing credentials, emphasizing the urgent need for stronger identity and access management controls. Threat actors increasingly exploit legitimate cloud services through social engineering, stolen session cookies, and misconfigurations, while remote code execution remains a persistent threat requiring timely patching. Backup infrastructure and recovery processes are targeted by ransomware attacks, making the adoption of isolated recovery environments with immutable backups crucial for cyber resilience. Advanced persistent threats exploit cloud storage for hosting malicious files and decoy documents, underlining the importance of continuous monitoring, security hygiene, and unified…
Fast Facts Non-compliance with emerging AI regulations, like the EU AI Act, can lead to severe fines up to 35 million Euros or 7% of global revenue, emphasizing the need for demonstrable API governance. Insecure and poorly governed APIs are causing significant innovation debt, with security holdups halting AI projects post-development, leading to wasted time and money. Legacy security tools generate overwhelming false positives, wasting valuable cybersecurity resources; advanced behavioral threat protection improves detection and operational efficiency. Securing APIs is a critical financial imperative, reducing regulatory fines, safeguarding AI project investments, and optimizing security workforce productivity in the AI-driven economy.…
Top Highlights A sophisticated iPhone hacking toolkit called “Coruna,” initially developed by U.S. contractor L3Harris for Western intelligence, has been stolen and sold to Russian and Chinese cybercriminals. The toolkit, which contains 23 exploits, was leaked when insider Peter Williams stole and sold parts of it for $1.3 million, enabling Russian espionage against Ukrainian targets. Coruna shares major vulnerabilities and internal module names with the previously exposed Operation Triangulation, indicating possible ties to L3Harris’s hacking units. The leak exemplifies the risks posed when nation-state cyberweapons are compromised and proliferated into the criminal underground. Underlying Problem The story centers around a…
Top Highlights OpenAI plans to acquire Promptfoo, enhancing security testing for AI systems, including adversarial prompts and safety compliance. Promptfoo’s tools, used by over 25% of Fortune 500 companies, will integrate into OpenAI’s Frontier platform for building AI coworkers. The acquisition addresses rising enterprise concerns over AI-related threats such as impersonation, malware, disinformation, and prompt injection. AI testing, similar to traditional security practices, is becoming essential at early development stages, with continuous evaluation to mitigate vulnerabilities in deployed AI systems. Underlying Problem OpenAI is planning to acquire Promptfoo, an AI testing startup, to improve the security of AI systems used…
The OT Security Time Bomb: Why Legacy Industrial Systems Are the Biggest Cyber Risk Nobody Wants to Fix
Top Highlights Legacy OT systems, often still running on outdated protocols and unsupported Windows versions, pose significant cybersecurity risks, enabling attackers to exploit vulnerabilities across interconnected infrastructure. Critical infrastructure sectors like energy and pharma face heightened risks due to the convergence of IT/OT networks, poor segmentation, and insufficient monitoring, leading to potential widespread disruptions and regulatory liabilities. Successful attacks typically start with IT breaches via phishing or weak access controls, then lateral movement into OT, exploiting outdated systems and weak network architecture—highlighting the importance of segmentation and proactive monitoring. Addressing the OT time bomb requires a phased approach: comprehensive asset…
Fast Facts Hackers often exploit legitimate, authenticated access rather than complex exploits, highlighting vulnerabilities in authorization, not just authentication. The true scope of an organization’s identity risk is underestimated due to incomplete inventory beyond managed applications, with attackers probing shadow IT and legacy systems. Single Sign-On (SSO) is not foolproof; it leaves gaps where assets aren’t modernized or can be bypassed, expanding attack surfaces and amplifying risks. Growing non-human identities and AI-driven automation complicate governance, while decision-making pitfalls like rubber-stamping approvals and latent entitlements undermine least privilege principles. Problem Explained The story centers around a significant security breach that occurred…
