5. Why do criminals wish to perform medical data theft?
Relating to cybersecurity, it's the what or how that must be unraveled and the why. Stealing sufferers’ or insured folks’s medical data is, at first, a really profitable enterprise for cybercriminal teams. How do they use folks’s well being info and personal data?
5.1. Extorting firms within the healthcare sector… and their sufferers
Generally the place malicious actors use ransomware to steal the medical data of hundreds or tens of millions of residents, they contact the attacked firms or establishments to demand a ransom fee to return the data and never expose it publicly.
For instance, RansomHouse, the felony group that efficiently attacked the Hospital Clínic, demanded a ransom fee of 4.2 million euros from the Catalan well being authorities.
Nonetheless, the direct victims of extortion aren't solely the healthcare sector firms but additionally their sufferers or policyholders.
In mid-November 2023, The Hunters Worldwide, a felony group that markets Ransomware-as-a-Service, carried out a cyberattack towards a medical heart specializing within the battle towards most cancers, the Fred Hutchinson Cancer Center.
Though the corporate claimed that the attackers had not succeeded in stealing its sufferers’ medical data, the gang has made public paperwork on its Darkish Net extortion portal that suggest in any other case.
As well as, they've despatched emails to completely different sufferers on the heart, threatening to publish their Social Safety numbers, medical data, or lab take a look at outcomes.
The criminals demand the fee of $50 from every sufferer to stop their private info from being utilized in different assaults or traded on the black market, making it simpler for different actors to commit fraud with data reminiscent of Social Safety numbers. If, because the malicious actors declare, they've been capable of steal the medical and private data of 800,000 sufferers, we may very well be speaking a couple of huge haul if the victims comply with the blackmail.
5.2. Advertising and marketing info to facilitate identification theft and monetary fraud
Even when firms or residents pay the ransom demanded by criminals, there isn't any assure that they'll hold their phrase. That is why each public administrations and cybersecurity consultants advise towards making any fee. This may even assist finance felony teams’ future actions, giving them extra assets to hold out extra complicated assaults.
In such a method that, after finishing up the medical data theft, cybercriminals can, along with extorting folks:
- Using this info to launch new, extra refined assaults that enable them to acquire extra important monetary acquire or injury firms, residents and public administrations.
- Promoting folks’s medical data on the Darkish Net. With info reminiscent of Social Safety numbers, different malicious actors can commit monetary fraud by stealing victims’ identities to acquire credit score from banks.
6. NIS2 Directive: Managing dangers successfully
