| The bad news
In March, a well-known security researcher warned that AI agents can now generate working exploits for previously unknown vulnerabilities in hours rather than weeks. As a result, bad actors threaten to identify and weaponize weaknesses faster than it’s possible to patch them. This is bad news across the board but particularly for healthcare. The sector already struggles with legacy endpoints, limited network oversight, and silos between IT and OT. The arrival of an even tighter exploitation window only makes successful hacks (and costly payouts) more likely. 72 hours Timing is everything in cybersecurity and can be the difference between a successful and thwarted attack. Right now, the median dwell time is three days. This means that once an attacker is in your network, there are about 72 hours before they move laterally, infect more widely, and inflict greater damage. Not only is this shorter than previous years but it’s faster than most healthcare incident response cycles. This is why getting teams on the same page and achieving a single shared view is crucial. Fighting back
Map out the infrastructure and onboard solutions that work across IT and OT. This provides a foundation for understanding what’s connected, its state, and its behavior. Ideally, this requires a single view across the network that eliminates false positives and reduces alert fatigue. Then, use architecture to limit the blast radius. Segmenting by device category – clinical equipment on one network, building systems on another, administrative systems on a third – means a breach in one zone stays in that zone. Finally, don’t just let the hacking side of the ledger benefit from AI. Once your monitoring is standardized and unified, intelligent interpretation of baseline activity quickly flags abnormalities. Remember, attackers can hide malware but they can’t hide traffic. Keeping a finger on the network pulse and understanding what’s healthy activity (and what’s not) can go a long way to identifying breaches as soon as they happen. — By MedCity Influencer David Montoya |
