Nonetheless, giant incidents just like the February 2024 ransomware assault on Change Healthcare are sufficient to shake up the {industry}. Within the wake of such a large breach, medical organizations of every type and sizes ought to take the chance to evaluate their safety postures.

What Occurred within the Change Healthcare Cyberattack

On February 21, Change Healthcare — the most important medical clearinghouse within the U.S. — suffered a ransomware assault, forcing it to take over 100 methods offline. A lot of its digital providers remained down for weeks, with full restoration taking till early April.

Every week after the assault, the notorious ransomware-as-a-service gang BlackCat claimed accountability. BlackCat was additionally liable for 2021’s Colonial Pipeline shutdown and a number of other assaults on well being care organizations all through 2023. This newest act towards Change Healthcare, nonetheless, stands as considered one of its most disruptive but.

As a result of Change and its dad or mum firm — UnitedHealth Group (UHG) — are such central {industry} gamers, the hack had industry-wide ripple results. A staggering 94% of U.S. hospitals suffered monetary penalties from the incident and 74% skilled a direct influence on affected person care. Change’s providers have an effect on one in each three affected person information, so the large outage created a snowball impact of disruptions, delays and losses.

Most of Change’s pharmacy and digital fee providers got here again on-line by March 15. As of early April, practically all the things is working once more, however the monetary fallout continues for a lot of enterprises reliant on UHG, because of substantial backlogs.

What It Means for the Broader Well being Care Sector

Contemplating the Change Healthcare cyberattack affected nearly the whole medical sector, it has important implications. Even the few medical teams untouched by the hack ought to think about what it means for the way forward for well being care safety.

1. No Group Is an Island

It’s tough to disregard that an assault on a single entity impacted nearly all hospitals within the U.S. This large ripple impact highlights how no enterprise on this {industry} is a self-contained unit. Third-party vulnerabilities have an effect on everybody, so due diligence and considerate entry restrictions are important.

Whereas the Change Healthcare hack is an excessive instance, it’s not the primary time the medical sector has seen giant third-party breaches. In 2021, the Crimson Cross skilled a breach of over 515,000 affected person information when attackers focused its information storage accomplice.

Well being care enterprises depend on a number of exterior providers and every of those connections represents one other vulnerability the corporate has little management over. In gentle of that danger, it should be extra selective about who it does enterprise with. Even with trusted companions like UHG, manufacturers should limit information entry privileges as a lot as potential and demand excessive safety requirements.

2. Centralization Makes the Business Weak

Relatedly, this assault reveals how centralized the {industry} has turn into. Not solely are third-party dependencies widespread, however many organizations depend upon the identical third events. That centralization makes these vulnerabilities exponentially extra harmful, as one assault can have an effect on the entire sector.

The well being care {industry} should transfer previous these single factors of failure. Some exterior dependencies are inevitable, however medical teams ought to keep away from them wherever potential. Splitting duties between a number of distributors could also be essential to cut back the influence of a single breach.

Regulatory adjustments could help this shift. Throughout a Congressional listening to on the incident, some lawmakers expressed issues over consolidation within the well being care {industry} and the cyber dangers it poses. This rising sentiment might result in a sector-wide reorganization, however within the meantime, non-public firms ought to take the initiative to maneuver away from giant centralized dependencies the place they’ll.

3. Well being Care Companies Want Dependable Response Plans

Well being care organizations must also pay attention to the size and price of UHG’s response timeline. It took weeks to revive the downed methods, even after reportedly paying a $22 million ransom to get well the stolen information. That’s far too lengthy.

Because the ransomware risk grows, companies on this {industry} should create emergency response plans.

The Change Healthcare ransomware assault additionally highlights the necessity for proactive safety. Whereas the precise reason behind the breach is unclear, BlackCat sometimes targets vulnerabilities in Distant Desktop Protocol or ConnectWise ScreenConnect. Each of those have patches obtainable, so proactive vulnerability administration might cease many assaults.

Vulnerabilities can come up in lots of areas of well being care, so detailed penetration testing and automatic assessments are essential to cowl sufficient floor. Automating updates is equally essential, as attackers transfer rapidly on this sector.

Medical teams should additionally emphasize worker coaching. Errors are a number of the most persistent threats on this {industry}, with 36% of information breaches stemming from misdelivery alone. Automating as a lot as potential and thorough cybersecurity coaching for all workers will decrease these dangers.

5. No One Is Secure

If the well being care sector doesn’t take the rest away from this incident, it ought to study no group is secure. UHG is among the {industry}’s largest forces and nonetheless fell sufferer to an assault. Comparable incidents can definitely have an effect on smaller firms with tighter safety budgets if they’ll trigger a lot injury to UHG.

It’s not essentially a matter of cybersecurity spending. Traditionally, safety has accounted for simply 6% of medical IT budgets, however greater than half of well being care organizations deliberate to extend their cybersecurity budgets in 2023. This development will seemingly proceed into 2024 and past, too. That development is essential, however the Change breach exhibits cash alone gained’t cease cybercriminals.

Investing in superior safety options is essential. Nonetheless, manufacturers should not turn into complacent simply because they’ve comparatively excessive cybersecurity budgets. Fixed vigilance and emergency restoration planning are nonetheless essential.

The Change Healthcare Hack Highlights the Want for Change

As well being care digitization rises, hospitals and their accomplice organizations will turn into more and more well-liked targets for ransomware gangs. This newest incident ought to function a wake-up name to this situation. Safety approaches within the sector should change.

The highway forward is lengthy and tough. Nonetheless, taking up this accountability now can save companies from substantial losses.
