Cyber premiums face pressure as AI accelerates attacks
Moody's flagged AI-driven speedups that can compress attack timelines from weeks to hours, alongside warnings that AI security tools are not a standalone fix.
Moody's has warned that cyber risk is becoming an increasingly significant corporate exposure for insurers, with pressure coming from two fronts: the underwriting risk tied to cyber policies and the operational risk of securing insurers' own systems. The firm frames the challenge around rising geopolitical tensions that are boosting both the frequency and complexity of cyberattacks, as well as the role of AI in strengthening capabilities for attackers and defenders.
In its 2026 Cyber Risk Outlook, Moody's said AI has amplified existing attack methods such as deepfakes, adaptive malware, and phishing rather than creating entirely new threat types. The firm also cautioned that attackers can scan networks for vulnerabilities at machine speed, often faster than defenders can patch them, compressing what used to be a weeks-long attack timeline into hours.
Moody's does not expect fully autonomous self-adapting malware for another three to five years, but it noted early indications of autonomous attacks already emerging. On the defense side, it said AI-powered security tools are not a silver bullet, warning that they can introduce new risks and require strong governance, citing issues such as unpredictable behavior and error accumulation.
The backdrop is a cyber insurance market that is growing but still small versus the exposure it is meant to cover. Munich Re estimates global cyber premiums at $15.3 billion in 2024, with North America accounting for 69%, and projects the market will more than double to over $30 billion by 2030, while noting cyber insurance remains less than 1% of total global property and casualty premiums, according to the source.
