18th November 2025 - Ransomware attacks rose sharply in October, increasing 41% month-on-month to 594 incidents, according to global cyber security firm NCC Group’s monthly Threat Intelligence Report. The surge indicates that threat actors are intensifying their operations ahead of what is typically the most active period for cyber crime. The fourth ‘golden quarter’ of the year sees peak consumer spending from Black Friday, Cyber Monday, and Christmas, presenting greater opportunity for cyber threat actors.
