Financial institutions are experiencing a rising wave of sophisticated ransomware attacks—3,348 incidents were documented—with attackers increasingly performing reconnaissance, lateral movement, data exfiltration, and “triple extortion” (encryption, data theft, and DDoS) to pressure victims. The report highlights high cost (average $6.08M per breach), long detection/containment timelines (~258 days), common initial vectors (malicious macro-laden financial templates leading to PowerShell backdoors), high ransom payment rates, and significant business, regulatory, and reputational impacts; it frames the problem as an urgent, sector-wide resilience gap and includes promotional content for a vendor solution.
