In the January 2026 edition of "This month in security," ESET Chief Security Evangelist Tony Anscombe highlights critical shifts in the global threat landscape. A primary focus is ServiceNow's remediation of CVE-2025-12420, a severe AI-driven vulnerability that could have allowed unauthenticated attackers to gain administrative access. Additionally, the month saw massive spam campaigns targeting Zendesk support systems and an alleged 1.4 TB data theft from Nike by a ransomware group.
Beyond specific incidents, wider industry trends indicate a significant change in executive priorities. According to the World Economic Forum, cyber-fraud has now surpassed ransomware as the leading concern for global CEOs. This shift emphasizes the growing sophistication of financial deception techniques and the need for security teams to adapt their defense strategies for the coming year.
