Are you concerned that AI-powered cyberattacks will make your personal data less secure?

Dell security chief John Scimone warned that artificial intelligence is significantly lowering the cost and skill barriers for cybercriminals. A recent review of banned accounts reveals that the vast majority of attackers now leverage AI to craft malicious software.

Why it matters

The shift toward AI-enabled attacks means traditional defenses may struggle against faster, more accessible threats. As entry barriers fall, security teams must increasingly rely on advanced AI to counter automated adversarial techniques.

A Dell review of 832 banned accounts found that 560 used AI to write malware, while 54 utilized the technology for network movement. The company has also deployed advanced AI models to monitor internal networks and remediate system vulnerabilities.

The players

John Scimone

He serves as the security chief at Dell and is responsible for overseeing the company's defense strategies against emerging cyber threats.

Dell

This multinational technology corporation develops and sells computers, servers, and data storage solutions for both consumers and enterprises.

The details

Security teams are increasingly adopting automated AI tools to keep pace with threats that now utilize machine learning to bypass conventional detection. By identifying and fixing vulnerabilities within internal code faster, organizations aim to mitigate the risks posed by these lower-barrier attacks.

March 2025 to March 2026: Dell conducted a review of 832 banned accounts.
June 5, 2026: Dell began using Claude Mythos Preview to secure its products.
October 20, 2026: John Scimone delivered his warnings at a New York symposium.

The Tech Race

The adoption of Anthropic's Claude Mythos Preview reflects a broader industry trend of integrating generative AI to automate vulnerability management and preemptively patch software code. This shift marks a departure from legacy manual security audits toward real-time, AI-driven protection.

As hackers gain more sophisticated tools, standard individual security practices like using multi-factor authentication become critical defenses against automated incursions. Users may also notice more robust, AI-powered security features integrated into their personal devices and software updates.

The takeaway

The democratization of cyberattack tools through AI necessitates a proactive approach to digital security for both corporations and individuals. Organizations are responding by deploying their own AI defensive models to identify and remediate vulnerabilities faster than human teams could manage alone.
