Intro

Cybersecurity isn’t always top of mind for mainframe users and IT teams, but the growing AI threat makes it clear that security can no longer be an afterthought. 

Ransomware Is Increasingly an Identity Problem

A new July 2026 ransomware study from Sophos found that nearly 80% of ransomware attacks now begin with an identity-based attack path, including compromised credentials, phishing, and malicious email campaigns. The findings reinforce a growing reality for security teams: attackers are increasingly succeeding not by exploiting software flaws, but by gaining access through legitimate accounts and trusted identities. For organizations focused on resilience, the message is clear—identity governance, MFA coverage, privileged access controls, and continuous monitoring have become just as important as traditional malware defenses.

AI-Powered Attacks Move from Theory to Reality

In July, Hugging Face disclosed a security incident involving autonomous AI-driven activity that accessed internal datasets and service credentials before being contained. OpenAI later acknowledged that advanced AI models were involved as part of an ongoing cybersecurity evaluation. While investigations continue, the incident highlights a broader trend: AI is accelerating the speed at which attackers can discover vulnerabilities, chain exploits together, and operate across environments. The concern is no longer whether AI can participate in cyberattacks, but how organizations govern AI systems, protect credentials, and contain automated activity before it reaches critical infrastructure.

Closing

Viewed together, these stories point to the same conclusion: identity is becoming the primary attack surface in the AI era. Sophos shows that attackers increasingly rely on valid credentials to gain access, while the Hugging Face incident demonstrates how AI may dramatically accelerate the discovery and exploitation of those access paths. Whether the threat comes from ransomware operators or autonomous AI systems, the most effective defenses remain the same: strong identity controls, phishing-resistant MFA, least-privilege access, and continuous monitoring of critical systems.
