Top Highlights Cyber threats are escalating with nearly 2,000 weekly attacks per organization in early 2025, driven by industrialized cybercrime, targeted social engineering, and rapid AI-enabled tactics. Leaders must adopt a core business resilience approach through “assume breach” strategies, robust identity controls, staff training, and incident response planning, positioning cybersecurity as a growth enabler. Dependency management and third-party oversight are crucial; organizations should ensure supply chain resilience and clear response plans for compromised partners. Cybersecurity requires translating technical risks into business language for board-level understanding, focusing on measurable outcomes such as faster detection, recovery, and sustaining revenue streams. Problem Explained…

Essential Insights ASUS released firmware updates to patch nine security vulnerabilities, including a critical authentication bypass flaw (CVE-2025-59366) in routers with AiCloud enabled. The vulnerability allows remote attackers to exploit a path traversal and OS command injection flaw, enabling unauthorized function execution without user interaction. To mitigate risks, users should immediately update their router firmware and disable internet-accessible services like remote access, port forwarding, and VPN. Previously, ASUS patched another critical flaw (CVE-2025-2492) exploited in the Operation WrtHug campaign, which hijacked devices globally and suspected to be used in Chinese hacking operations. Underlying Problem Recently, ASUS released a firmware update…

Fast Facts The RomCom malware family was delivered via SocGholish, a JavaScript loader exploiting compromised websites, marking the first observed use of SocGholish for RomCom distribution. The attack is attributed with medium-to-high confidence to Russia’s GRU Unit 29155, targeting entities with ties to Ukraine, using fake browser updates to trick users into installing malware. Threat actor RomCom employs spear-phishing and zero-day exploits to breach networks, deploying tools like the Mythic Agent and custom backdoors, primarily targeting Ukraine and NATO-related organizations. The attack chain is rapid, taking less than 30 minutes from infection to payload delivery, highlighting SocGholish’s widespread threat and…

Summary Points Cyber threat activity surged significantly in October, following a 28% increase in September, as threat actors accelerate operations ahead of peak holiday shopping season. The October spike aligns with the “golden quarter” (Black Friday, Cyber Monday, Christmas), bringing increased opportunities for cybercriminals. Industrial sectors remained the top targets, accounting for 28% of attacks, with consumer discretionary and healthcare also heavily impacted. NCC monitors leak sites associated with ransomware groups to track attacks, highlighting the intensifying cyber threat landscape during this period. The Issue The report highlights a notable increase in cyber attacks during the fall, especially in October,…

Essential Insights Managing Non-Human Identities (NHIs) is crucial for securing cloud infrastructures across industries like healthcare, finance, and travel, where machine identities facilitate critical transactions and data protection. Effective NHI management requires lifecycle oversight—from discovery to decommissioning—to detect anomalies, ensure security, and reduce vulnerabilities in dynamic, ephemeral environments. Leveraging advanced technologies such as AI, ML, and blockchain can enhance real-time monitoring, automate processes, and provide secure, transparent management of machine identities. Building a security-first organizational culture through education, collaboration, and adoption of identity-centric and DevSecOps practices is essential for addressing complex NHI challenges and future-proofing cybersecurity defenses. Problem Explained The…
