November 2025: Major Cyber Attacks Ransomware Attacks, Data Breaches

November 2025 proved to be another pivotal month in the global cybersecurity landscape. Organizations across sectors faced widespread data breaches, major operational disruptions, and highly coordinated supply chain attacks.

One of the most alarming incidents was the cyberattack on the London Councils, which triggered emergency service disruptions impacting more than half a million residents — a powerful reminder that local authorities remain extremely vulnerable to full-scale operational shutdowns. In the digital finance sector, the $120 million Balancer DeFi breach showcased the increasing sophistication of crypto-focused threat actors, who continue to exploit logic gaps in widely adopted blockchain protocols.

Several high-profile institutions also suffered exposure of sensitive data this month. Notable victims included The Washington Post, the University of Pennsylvania, and real estate financial services leader SitusAMC. Even consumer-facing giants like DoorDash were affected, underscoring that employee-targeted social engineering attacks remain one of the most reliable infiltration tactics for cybercriminals.

Across these incidents, a few critical themes stand out. Third-party and supply-chain exposure has become one of the most severe — and least controlled — security risks facing modern enterprises. Data-theft-only extortion campaigns are rising sharply, meaning organizations can no longer rely on ransomware encryption as the first indicator of compromise; silent exfiltration now precedes detection in many breaches. Additionally, both public and private sector environments showed ongoing challenges around rapid detection, identity compromise, and effective segmentation of critical systems.

Our NCSC-Assured Cyber Incident Planning & Response training enables security teams to identify and contain threats at speed. Our Incident Response Playbooks and Cyber Tabletop Exercises strengthen organizational readiness, ensuring teams can act decisively against emerging and evolving attacks.

Are You Prepared for the Next Wave of Healthcare Cyber Threats?

Image
In the current digital landscape, where organizations highly depend on online communications, cybercriminals are become more than just a nuisance. They are targeting every kind of institution across every sector, which means contrary to their traditional ways, they aren’t just stopping at making finance or IT firms their targets, but they’re also targeting hospitals, clinics, as well as telemedicine apps. Hackers are well aware that the healthcare sector is most vulnerable and likely to give in to their ransom demands as the medical professionals have to deal with emergency cases of patients and can hardly afford any delays or interruptions. Also, the patient’s data & information are extremely sensitive, and the healthcare sector has a responsibility to keep it private ensuring it is safe from unwanted outside access. It also doesn’t help that a large number of healthcare centres and institutions continue to operate with IT systems & equipment that are long outdated, along with...
