Every merger or acquisition follows a familiar script: two companies, two networks, two security stacks, one clock. Partners who deliver Day-1 access quickly, then guide a clean path to standardization and modernization, help customers realize deal value sooner. Do that repeatedly and you become the trusted M&A partner across the portfolio.

It was a quiet Monday morning until John, head of IT, opened his laptop and saw 424 new support tickets. Users across the office were reporting issues like “apps won’t load” and “internet not working.” After hours of investigation that stretched into the next day, the team traced the problem to a branch router overwhelmed by malformed DNS queries from a misbehaving IoT device.

Millions of homes, businesses, and hospitals depend on solar power, a clean and cost-effective source of renewable energy. Adoption has accelerated worldwide thanks to major government initiatives such as the Inflation Reduction Act (IRA) in the U.S., the Renewable Energy Directive (RED II) in the EU, the Smart Export Guarantee in the UK, and Australia’s Small-scale Renewable Energy Scheme (SRES). As clean energy infrastructure expands, a new vulnerability is emerging.

JSCEAL is an information stealer that’s been targeting users of cryptocurrency applications. As reported by Check Point Research (CPR) in July 2025, JSCEAL has developed into a more advanced form. In a new campaign observed by Cato CTRL in August 2025, JSCEAL has adopted a revamped command-and-control (C2) infrastructure, enhanced anti-analysis safeguards, and an updated script engine designed for increased stealth. The campaign remains active.

Phishing remains one of the most effective methods for stealing credentials and breaching enterprise environments. Despite advanced email and browser protections, attackers now leverage AI, and automation to outpace traditional defenses. The Verizon 2024 Data Breach Investigations Report found that 68% of breaches involve the human element, often triggered within seconds of a phishing lure, just 21 seconds to click and 28 seconds to submit credentials.

On Wednesday, December 3, a critical remote code execution (RCE) vulnerability in React Server Components (RSC), dubbed React2Shell (CVE-2025-55182), was disclosed. The CVE was discovered by security researcher Lachlan Davidson. It quickly gained traction with multiple third-party proof of concepts (PoCs) being published of varying quality and credibility.

AI tools have proved their worth in the workplace. They help us write, research, code, plan, and automate. They’re making employees faster and more productive, and helping businesses move and innovate at a pace that wasn’t possible before. But AI’s rise wasn’t orchestrated by IT. It didn’t always arrive through formal adoption plans or procurement cycles. It turned up in shared links to popular GenAI and other tools, self-sanctioned and adopted by users in minutes.

Claude Skills is a new feature from Anthropic that has gained rapid adoption, with more than 17,000+ GitHub stars already since its launch in October 2025, allowing users to create and share custom code modules that expand Claude’s capabilities and streamline workflows. But as this ecosystem grows, Cato CTRL uncovered a serious oversight into how Skills are executed.
