Cyberattacks on the healthcare sector are a rising menace in Latin America, and the massive quantity of confidential information these organizations deal with makes these assaults a prime concern.
The worth of healthcare information within the unlawful market, reminiscent of the non-public, medical and monetary data of sufferers and healthcare corporations, creates an interesting goal for menace actors. This will have severe penalties for the privateness and data security of those organizations. Cyberattacks might result in reputational dangers, interruption of operations, information theft and disclosure and even the lack of human lives when medical items and providers are unavailable.
So what do healthcare organizations and sufferers have to find out about cyberattacks on the healthcare sector in Latin America?
In accordance with the IBM Safety X-Power Menace Intelligence Index 2023 report, the proportion of incidents to which X-Power Incident Response has responded within the healthcare sector has remained at roughly 5% to six% of complete incidents over the previous three years. Ransomware outpaced different assaults in Latin America, accounting for 32% of the circumstances to which X-Power responded.
Moreover, the principle entry vectors for healthcare corporations in Latin America are the exploitation of public-facing purposes (T1190), the abuse of legitimate accounts (T1078) and the exploitation of exterior distant providers (T1133).
3 important threat elements
Exploitation of Public-Going through Purposes
IBM X-Power Incident Response noticed that attackers primarily exploit weaknesses and vulnerabilities in providers and applications with web entry, particularly web sites. In different circumstances, they exploit vulnerabilities in internet servers (Apache Tomcat, outdated variations of Apache and outdated security patches, for instance).
Abuse of Legitimate Accounts
Attackers exploit distant system accounts and externally obtainable providers, reminiscent of digital non-public networks (VPNs), community units and distant desktops. In different circumstances, they exploit inactive accounts or accounts that don’t expire passwords (exfiltrated on the Deep Net) with dictionary-based or credential-stuffing assaults.
Exploitation of Exterior Distant Providers
Exploiting distant entry providers reminiscent of Citrix desktops, entry gateways and VPNs permits attackers to connect with inside healthcare enterprise sources from exterior areas.
IBM X-Power incident response advice
These are some examples of the principle intrusion vectors that IBM X-Power Incident Response has recognized in healthcare corporations within the Latin American area. All healthcare organizations within the area should put together to face these threats and have enough security measures to guard affected person data’s privateness and security.

- Implement security operations facilities to detect and handle security breaches via early alerts, present real-time infrastructure security monitoring, implement preventive measures and enhance responsiveness to future assaults.
- Embody extra endpoint safety layers on the technological infrastructure of healthcare corporations.
Scale back vendor threat
To mitigate the principle entry vectors, remember the next:
- Segregate exterior servers and providers from the remainder of the community with a DMZ or separate internet hosting infrastructure.
- Handle privileged accounts by implementing minimal privileges for service accounts.
- Keep all computer systems, servers and medical units with patching and vulnerability administration processes.
- Scan exterior methods for vulnerabilities recurrently.
- Audit person accounts for uncommon exercise and disable or delete these which might be not wanted.
- Make sure that purposes don’t retailer delicate information or credentials insecurely (clear textual content).
- Enhance the insurance policies and administration of passwords for all applied sciences which might be a part of the well being sector firm to make sure security in system entry. It’s endorsed that these passwords be longer than 12 characters, together with particular symbols and numbers, along with verifying the relevance of multifactor authentication within the case of important providers.
- Disable or block remotely obtainable providers which may be pointless.
- Conduct analysis on the Deep Net to determine attainable data leaks, together with credentials.
Rising to satisfy the menace
