North Korean state-sponsored ransomware operators are operating a marketing campaign actively focusing on healthcare companies, according to an advisory issued by the FBI alongside the Cybersecurity and Infrastructure Security Company (CISA) and the Treasury Department.
The Maui ransomware strain has been used by North Korean hackers considering the fact that “at the very least Could 2021”, in accordance to the joint advisory.

The FBI also states it is noticed and responded to “multiple ransomware incidents” at health care providers throughout the sector, in which the malicious program is being employed to encrypt servers responsible for health care providers.
These incidents involve critical things such as digital healthcare information solutions, as properly as diagnostic, imagining, and intranet providers. In some circumstances, these were identified to have disrupted the services delivered by the specific organizations for extended durations.
The CSA mentioned that the condition-sponsored cyber criminals likely think health care companies would be keen to pay back huge ransoms because they supply expert services critical to human life and wellbeing.
“Because of this assumption, the FBI, CISA, and Treasury evaluate North Korean condition-sponsored actors are possible to continue on targeting HPH Sector companies,” it warned.
Minimising the ransomware risk
Despite the fact that it’s not known exactly how the hackers attain first entry to these healthcare systems, the CSA notes the ransomware is built for guide execution. In essence, the remote actor will use a command-line interface to interact with the malware and to identify which documents to encrypt.
To assist mitigate likely hurt, companies are urged to apply and retain a selection of practices. These contain limiting accessibility to knowledge making use of authentications and digital certificates, minimising use of administrative accounts, turning off network device administration interfaces for large area networks (WANs), as nicely as applying a host of other resources to secure personalized identifiable data.
Furthermore, the authorities stated health care organizations really should stick to its list of cyber security tips for making ready for, mitigating, and stopping ransomware. Crucially, on the other hand, the doc advises organizations versus caving in to the requires of the cyber criminals.
A increase in healthcare attacks
Regrettably, ransomware attacks on health care organisations and providers are growing at a swift rate. Again in June, cloud security firm Zscaler’s 2022 ThreatLabz Ransomware Report discovered that attacks on the healthcare sector experienced grown exponentially, with double extortion ransomware attacks increasing by a staggering 650% in excess of 2021.
Somewhere else, an Outpost24 report very last year uncovered that 90% of web apps used by healthcare operators are thought of ‘critically exposed’ and highly inclined to vulnerabilities.
That report also identified US health care businesses have a a lot bigger attack area when when compared to EU pharmaceutical companies, inspite of US health care vendors 30% much less external web apps.
“Any kind of information breach and downtime for health care organizations can be deadly, thus they have to just take a proactive stance to identify and mitigate potential security issues just before critical care can be impacted,” reported Nicolas Renard, security researcher at Outpost24, at the time.
