AI-driven tools are empowering even amateur hackers, increasing ransomware attacks and putting critical sectors like healthcare at greater risk

New Delhi, May 5, 2026 — Cybercrime has entered a far more dangerous phase as artificial intelligence lowers the barrier for launching attacks, former Federal Bureau of Investigation cyber division assistant director Cynthia Kaiser has warned in an interview with Times Radio.

“Cyber criminals are stealing a generation of wealth from our nations,” Kaiser said, adding that the impact is no longer confined to large corporations but extends to everyday businesses and public services. “It’s affecting our main streets… the businesses we go to every day, as well as the organisations that employ us,” she added.

Kaiser highlighted the growing threat of ransomware attacks, particularly those targeting critical infrastructure such as hospitals. “We see ransomware actors targeting hospitals, endangering the lives of our citizens,” she said, noting that cybercrime groups have increasingly abandoned earlier informal restraints.

What makes the current phase more alarming, according to Kaiser, is the role of AI in expanding the pool of attackers. While sophisticated cybercriminal groups are using AI to enhance efficiency, the bigger concern is the rise of inexperienced hackers now equipped with powerful tools.

“The amateurs — those who couldn’t conduct an attack yesterday — now have some of the most powerful tools humanity has ever had in their hands,” she said. Though these attacks may lack sophistication, their sheer volume is overwhelming cybersecurity teams worldwide.

Kaiser pointed out that the surge in low-level but persistent cyberattacks is creating significant operational strain across organisations, increasing vulnerabilities and response fatigue.

One of the most disturbing trends is the targeting of healthcare institutions. “Hospitals aren’t off limits anymore,” she said, adding that studies have linked ransomware attacks to at least 47 deaths between 2016 and 2021 due to disruptions in medical services.

Despite the escalating threat, Kaiser emphasised that basic cybersecurity practices remain highly effective. She advised individuals and organisations to use strong, complex passwords, enable multi-factor authentication, and deploy reliable antivirus and firewall protections.

She also cautioned against urgency-based scams, a common tactic used by cybercriminals. “If someone is rushing you, they’re trying to ensure you don’t think before you click,” she said, urging users to pause and verify before responding to suspicious messages.

As AI continues to evolve, experts warn that the line between sophisticated and amateur cybercrime is rapidly blurring, making vigilance and preparedness more critical than ever.
