Summary Points Adversaries are exploiting AI and zero-day vulnerabilities faster, shrinking the window for detection and response. Many organizations underutilize cloud security controls due to deployment complexity and risk of disruption. Native offers a platform to enforce security intent across multiple clouds, translating it into provider-specific configurations without adding extra layers. The company raised $42M to commercialize its solution, founded by cloud security veterans with high-profile industry experience. Native Introduces Security Control Plane for Multicloud Environments Native has launched a new platform designed to improve security across multiple cloud services. As cyber threats grow more advanced, companies need stronger ways…
Essential Insights The ransomware group Interlock exploited a critical Cisco firewall vulnerability (CVE-2026-20131) as a zero-day for over a month before a patch was released, highlighting the threat of unpatched zero-day vulnerabilities. Amazon’s honeypot system uncovered initial attacks on January 26, confirming that Interlock had a significant head start in exploiting the vulnerability before it was publicly patched. Interlock’s attack tools were linked to their ransomware operation, possibly a RaaS offshoot of Rhysida, targeting sectors like education, healthcare, and government, emphasizing widespread risk. The incident underscores the critical need for defense in depth due to the challenge zero-day exploits pose,…
Quick Takeaways The U.S. CISA has issued an urgent alert urging organizations to strengthen security of endpoint management systems, especially Microsoft Intune, after a cyberattack on Stryker Corporation exploited its environment. The attack highlights rising threats targeting endpoint management platforms, enabling attackers to deploy malicious apps, modify configurations, wipe devices, or move laterally across networks. CISA recommends implementing Microsoft’s best practices, including least-privilege role design, phishing-resistant multi-factor authentication, and multi-admin approval for sensitive operations to mitigate risks. The agency emphasizes the critical need for organizations, particularly in critical infrastructure, to audit and secure their Intune configurations to prevent exploitation of…
Top Highlights CISA has added a high-severity, actively exploited vulnerability (CVE-2025-66376) in Zimbra Collaboration Suite, specifically in its Classic UI, enabling malicious email-based cross-site scripting (XSS) attacks. Exploiting this flaw allows attackers to execute scripts within user sessions, risking data theft, session hijacking, or unauthorized commands; remediation is urgent. Zimbra released patches (versions 10.1.13 and 10.0.18) to address this, including security and performance improvements, with timely patch application essential, especially as version 10.0 has reached EOL. CISA mandates all federal agencies patch by April 1, 2026, and recommends private sector organizations do the same or cease using the vulnerable versions…
Quick Takeaways AI-driven “vibe coding” is exploited by cybercriminals to rapidly create malware, leading to widespread infections through disguised malicious files on popular platforms. A major campaign discovered in January 2026 involved over 443 infected ZIP files, distributing malware that used 48 variants of a malicious DLL to infect users across multiple countries, especially the U.S. and UK. The malware employs dynamic command-and-control servers, fileless techniques, and utilizes multiple cryptocurrency wallets, amassing nearly $11,500, with actual gains possibly higher due to privacy coins. Infections occur via trojanized files that load malicious DLLs, redirect browsers, and install fake dependencies to distract…
Rising Threats to Endpoint Systems Post-Stryker Breach: Urgent Call for Stronger Defense
Summary Points The U.S. CISA is monitoring increased malicious cyber activity targeting endpoint management systems, especially following the March 11, 2026, attack on Stryker, linked to suspected Iran-linked threat actors, which disrupted medical device operations. Stryker is actively restoring its systems, prioritizing customer support, with ongoing efforts to bring electronic ordering back online amid the incident’s impact on supply chains. CISA recommends organizations enhance cybersecurity by applying Microsoft’s best practices for securing endpoint management tools, including least privilege access, multi-factor authentication, multi-admin approval, and zero trust principles. The agency emphasizes collaboration with federal partners like the FBI, and urges organizations…
Cybersecurity Shakeup: DarkSword Emerges as ShieldGuard Falls, NK IT Workers Profit Amid Chaos
Top Highlights Cybersecurity researchers identified “DarkSword,” an iOS exploit kit linked to Russian-backed groups, capable of stealing sensitive data from older iPhones, though patched by Apple. The “ShieldGuard” crypto scam browser extension was dismantled after it was found to harvest users’ wallet and browsing data, revealing a broader malicious network. North Korea operates a network of up to 100,000 fake IT workers across 40+ countries, generating around $500 million annually through infiltration and espionage activities. A major Cisco firewall zero-day flaw was exploited by ransomware group Interlock weeks before its official patch, enabling remote code execution and persistent control over…
Summary Points Most cloud breaches are due to simple misconfigurations, not advanced hacking, with nearly all incidents caused by overlooked settings or errors made by humans. The scale of damage from these breaches is enormous, with U.S. companies averaging over $10 million per event, and incidents like Snowflake affecting hundreds of millions of users due to basic login lapses. Common mistakes include leaving storage open publicly, neglecting multi-factor authentication, and ignoring logs, which collectively prolong the time hackers can exploit vulnerabilities—sometimes for months. Immediate actions such as enabling MFA, auditing storage permissions, activating comprehensive logs, and deploying Cloud Security Posture…
Quick Takeaways Black Kite has launched Open FAIR-based Risk Assessments, automating financial impact calculations for cyber risks like data breaches and ransomware, streamlining the CRQ process within its AI-powered assessments. This integration allows real-time, scenario-based modeling during onboarding and periodic reviews, enabling organizations to evaluate how vendor decisions impact financial risk and compare vendors consistently. Benefits include instant quantification of financial risks, enhanced decision-making for vendor selection and insurance, and tracking risk trends over time by combining assessment data with continuous monitoring. Advanced features support automated model population, scenario customization, and private modeling, empowering organizations to make data-driven, financially focused…
Quick Takeaways North Korea-linked group WaterPlum has introduced a sophisticated, modular malware called StoatWaffle, deployed via compromised VSCode repositories mimicking blockchain projects, and activated automatically when developers open trusted folders. The malware’s infection chain involves downloading and executing scripts to install Node.js if absent, then connecting to command-and-control servers to fetch and run second-stage modules like credential stealers and remote access Trojans, providing persistent, deep system access. This campaign leverages stealthy triggers—specifically the ‘folderOpen’ setting in VSCode—enabling silent infection without user prompts, making it a particularly insidious threat targeting blockchain and developer communities. Security experts advise developers to scrutinize VSCode…
