Why Holidays Are Peak Ransomware Season

As the year winds down, cyber attackers are gearing up. Semperis’ 2025 Ransomware Holiday Risk Report reveals that over half of ransomware attacks hit during weekends or holidays, when most organisations sharply reduce monitoring and response capability. With identity systems at the heart of almost every major breach, and with global cybercrime costs set to reach USD 10.5 trillion, the stakes have never been higher.

Jeff Wichman, Director of Incident Response at Semperis, discusses what really happens when attackers strike, why identity weaknesses amplify the damage, and what frontline ransomware negotiations can teach business leaders. A grounded, visual, and highly practical conversation on how every organisation – from SMEs to large enterprises – can strengthen resilience before the next holiday season.
