The Rapid Growth of Telemedicine and Its Consequences

Telehealth adoption skyrockets

Telehealth was once a niche option limited to rural outreach and follow-up care. The COVID-19 pandemic shattered those boundaries, and usage has continued to climb. In 2020 alone, telehealth claims to private insurers increased by 4,347 % compared with 2019, and analysts projected a seven-fold growth by 2025 healthsectorcouncil.org. Hospitals embraced the technology: the American Hospital Association reported that 86.9 % of U.S. hospitals offered telehealth services by 2022, up from 72.6 % in 2018 aha.org. Physicians followed suit; by 2024, 71.4 % of doctors used telehealth weekly, almost triple the 25.1 % usage rate in 2018. Behavioral health providers are particularly reliant on video visits, with psychiatrists using telehealth for more than one-fifth of their weekly appointments.

This surge brings tremendous benefits: greater access for rural patients, continuity of care for chronic conditions, and decreased infection risk. However, it also expands the attack surface for cybercriminals. The combination of lax security controls, remote work and connected devices has made healthcare one of the most targeted sectors for cyberattacks. The FBI reported 460 ransomware attacks against the U.S. healthcare sector in 2025, far more than any other critical infrastructure sector. Since 2020, more than 3,200 hacking incidents have been reported to the Department of Health and Human Services’ Office for Civil Rights, affecting 574 million people. These statistics underscore the urgent need for stronger safeguards.


Understanding e-health versus telemedicine

Telemedicine refers specifically to the provision of clinical services—diagnosis, treatment or consultation—via telecommunications. Telehealth is broader; it encompasses non-clinical activities such as remote monitoring, patient education and administrative services. Both fall under the umbrella of e-health, which includes electronic health records (EHRs), mobile health apps and health information exchange. Because telemedicine services exchange electronic protected health information (ePHI), they are subject to privacy laws like the U.S. Health Insurance Portability and Accountability Act (HIPAA) and the European Union’s General Data Protection Regulation (GDPR). For a deeper discussion of telemedicine’s benefits and challenges, see Fredash Education’s article on maximizing healthcare efficiency through telemedicine.


Categorizing Security Risks: Confidentiality, Integrity and Availability

Security threats in e-health can be grouped into the CIA triad—compromise of confidentiality, integrity and availability. Recognizing these categories helps organizations develop targeted defenses.

Confidentiality risks

Confidentiality attacks aim to steal or expose patient information. A systematic review of telehealth privacy risk factors found that environmental issues (lack of private spaces, unauthorized family members overhearing conversations), technology gaps (unstable internet connections, unencrypted devices) and operational factors (insufficient training or unclear policies) undermine confidentiality pmc.ncbi.nlm.nih.gov. Hackers exploit these weaknesses through techniques such as:

  • Credential harvesting and phishing. Ransomware gangs often gain initial access via phishing emails. In late 2025, healthcare ransomware attacks increased by 36 % over the previous year, and 96 % of incidents involved data exfiltration. Attackers lure staff into revealing login credentials or clicking malicious links that install malware.
  • Third-party vendor compromises. Modern healthcare relies on cloud providers, billing processors and file-transfer services. When one of these business associates is breached, the impact cascades. During a 2024 attack on a major clearinghouse, over 190 million Americans’ health records were compromised, contributing to a record total of 259 million individuals affected by healthcare breaches by the end of the year. AHA analysts found that over 80 % of stolen records were taken from third-party vendors rather than hospitals meriplex.com.
  • Insider misuse. Disgruntled employees or untrained staff may intentionally or accidentally leak data. Environmental factors—such as working from home on personal devices or taking calls in public—heighten this risk.

Integrity risks

Integrity attacks compromise the accuracy and trustworthiness of medical data. Examples include:

  • Clinical data manipulation. Attackers might alter lab results or medication orders, leading to misdiagnosis or incorrect treatment. A White House threat report documented numerous cases where ransomware gangs modified EHR data during extortion attempts.
  • Financial exploitation. Cybercriminals may redirect payments or manipulate billing systems. The U.S. government’s NIST smart home integration paper warns that voice-enabled devices could be used to spoof identities and authorize fraudulent transactions nist.gov.
  • AI poisoning. As artificial intelligence becomes integral to diagnostics and triage, attackers can poison training data or deploy deep fakes. The AHA warns that autonomous AI-facilitated attacks are emerging; they leverage AI to generate convincing audio or video deep fakes and may use “data poisoning” to corrupt algorithms aha.org.


Availability risks

Availability attacks disrupt care delivery by denying access to systems or devices. Major examples include:

  • Ransomware and double-extortion. Ransomware remains healthcare’s top threat. Attackers encrypt systems and exfiltrate data, demanding payment for decryption keys and for not publishing stolen information. Healthcare experienced 86 ransomware attacks in a single three-month period in late 2025, representing 32 % of all known incidents. Organizations with immutable backups and rehearsed recovery plans recovered in hours, while others required weeks.
  • Distributed denial-of-service (DDoS) attacks. Overwhelming network traffic can render telehealth platforms unusable. IoT devices, if hijacked, can form botnets that amplify these attacks.
  • Unpatched IoMT devices. A 2022 FBI report found that 53 % of connected medical devices had at least one known critical vulnerability, and one in five devices ran unsupported operating systems. Such vulnerabilities allow attackers to take devices offline or disrupt vital patient monitoring.

These threats illustrate why confidentiality, integrity and availability must be addressed holistically. The next sections explore real-world breaches and regulatory frameworks.


Real-World Incidents: Lessons Learned

The Change Healthcare ransomware attack (2024)

In February 2024, a ransomware group known as ALPHV/BlackCat attacked Change Healthcare—a clearinghouse processing roughly 15 billion health transactions annually. The intrusion disrupted claims processing and prescription services across the U.S. A survey of hospitals conducted by the American Hospital Association revealed that 74 % experienced direct patient-care impacts such as delayed authorizations, 94 % suffered financial strain, and 60 % needed two weeks to three months to restore normal operations aha.org. This event underscores that cybersecurity breaches are not just data-theft crimes; they are threats to life and institutional solvency.


Rising ransomware and the double-extortion model

The AHA’s 2026 cyber-risk advisory notes that hackers increasingly steal data before encrypting systems, a technique called double extortion. In 2025 alone, the healthcare sector suffered 460 ransomware attacks, and cumulative hacking incidents since 2020 affected 574 million individuals. The advisory warns that nation-state adversaries—especially from Russia, Iran, China and North Korea—encourage proxy groups to launch ransomware against hospitals for plausible deniability. Additionally, attacks on mission-critical third parties produce a “ransomware blast radius” that disrupts multiple providers simultaneously. These trends emphasize the need for robust third-party risk management.


IoMT vulnerabilities and the PATCH Act

The proliferation of networked medical devices (IoMT) offers clinical advantages but expands the attack surface. Industry research predicts that smart hospitals will deploy over 7 million IoMT devices by 2026, more than double the number in 2021. To address these vulnerabilities, the U.S. Food and Drug Administration (FDA) implemented the PATCH Act and related guidance, requiring manufacturers to submit cybersecurity plans, provide software bills of materials and design update mechanisms into devices. Healthcare providers must inventory devices and segment clinical networks to prevent lateral movement meriplex.com.


The cost of a breach

Breaches are expensive. IBM’s 2025 cost of a data breach report found that the average U.S. healthcare breach cost $10.22 million, significantly higher than the global average of $4.44 million. The average breach lifecycle lasted 279 days—five weeks longer than the global average. A separate HIPAA Journal analysis attributes high costs to the value of medical data on the black market and mandatory notification requirements. Hospitals that detect breaches internally can shorten the lifecycle and save millions hipaajournal.com.


Regulatory Frameworks and Standards

HIPAA, HITECH and CISA

The Health Insurance Portability and Accountability Act (HIPAA) establishes national standards for protecting ePHI. Its Privacy and Security Rules require administrative, physical and technical safeguards; the Breach Notification Rule mandates reporting of incidents. The Health Information Technology for Economic and Clinical Health (HITECH) Act strengthened enforcement and encouraged adoption of EHRs. The Cybersecurity Information Sharing Act (CISA) promotes sharing threat information across sectors. Telehealth providers must comply with these regulations while adapting to evolving technology healthsectorcouncil.org.


HIPAA guidelines for telemedicine

To meet HIPAA obligations during remote visits, providers should:

  1. Audit communication technologies. Use platforms that meet HIPAA’s technical safeguards, including encryption, access control and audit trails.
  2. Conduct a formal risk analysis. Identify vulnerabilities in hardware, software and workflows; implement remediation plans.
  3. Develop policies and train staff. Document telehealth procedures, verify patient identity, obtain informed consent and ensure Business Associate Agreements are in place.
  4. Secure documentation. Record telehealth encounters in the same manner as in-person visits and protect data at rest and in transit hipaajournal.com.

Updated requirements in 2025–2026

In January 2025, the Department of Health and Human Services (HHS) revised the HIPAA Security Rule. Previously “addressable” safeguards—such as multi-factor authentication (MFA), end-to-end encryption, regular vulnerability scanning and biannual penetration testing—became mandatory. Backup retention of ePHI was limited to 48 hours, and organizations must restore systems within 72 hours following disruptions. Compliance costs are estimated at $9 billion initially and $34 billion over five years, but HHS argues the investment will reduce breach impacts.

Regulators also extended telehealth flexibilities. HHS allows Medicare patients to receive non-behavioral telehealth services at home through December 31, 2027, with no geographic restrictions. Federally Qualified Health Centers and Rural Health Clinics can act as distant site providers through the same date telehealth.hhs.gov. These extensions solidify telehealth’s role in routine care.


NIST guidance and smart-home integration

The National Institute of Standards and Technology (NIST) published a 2025 white paper on telehealth smart-home integration that highlights new vulnerabilities. The report warns that voice-enabled assistants can be exploited for identity spoofing and recommends controls such as strong access control, phishing-resistant authentication, continuous monitoring, data encryption, network segmentation and governance frameworks nist.gov. NIST’s guidance reinforces the need for zero-trust architectures and emphasizes that security must be built into device procurement and deployment.


Solutions: Building a Robust Security Posture

Protecting patient data in the digital age requires layered defenses, organizational discipline and continuous improvement. Below are practical strategies for healthcare leaders, IT teams and clinicians.

1. Governance and Risk Management

  • Perform comprehensive risk analyses. OCR penalties in 2025 revealed that failing to conduct enterprise-wide risk analyses was a common deficiency, with fines ranging from $25,000 to $3 million. A thorough risk analysis should inventory all assets (systems, devices, vendors), identify threats and vulnerabilities and quantify their likelihood and impact.
  • Establish a cybersecurity governance program. Assign responsibility for information security to a cross-functional team that includes clinicians, IT, compliance and senior leadership. Develop policies for data classification, incident response and vendor management.
  • Manage third-party risk. Maintain an inventory of all vendors that handle ePHI, require cybersecurity questionnaires and audits, insist on contract clauses mandating MFA, encryption and timely patching, and categorize vendors by risk tier. Build the governance program before an incident occurs.


2. Technical Safeguards

  • Encrypt data at rest and in transit. Adopt end-to-end encryption for video calls, messaging and file transfers. Use secure protocols (HTTPS, TLS) and ensure encryption keys are managed securely.
  • Deploy multi-factor authentication (MFA). Enforce MFA for all remote logins, administrative functions and device access. HHS’s 2025 update makes MFA mandatory for administrative and critical system access.
  • Implement network segmentation and zero-trust. Separate clinical systems from corporate IT and guest networks. Adopt Zero Trust Network Access (ZTNA) so that every connection—whether from the hospital or a remote worker—is authenticated and authorized. Limit lateral movement by isolating IoMT devices from core networks.
  • Patch management and vulnerability scanning. Ensure all software and firmware, including IoMT devices, are patched promptly. Conduct vulnerability scans at least every six months and penetration tests twice a year.
  • Immutable backups and disaster recovery. Maintain off-site, air-gapped backups of critical systems and test restoration procedures. Organizations that rehearsed downtime procedures recovered from ransomware in hours. Under the new rules, backups must be retained for 48 hours with restoration within 72 hours.
  • Identity and access management (IAM). Implement least-privilege access, regularly review user permissions and immediately disable accounts when employees leave or change roles. Use role-based access control to limit who can view or edit sensitive data.
  • Secure IoMT devices. Create an asset map of all connected devices, monitor network traffic for anomalies and ensure devices can receive over-the-air updates. Procure devices only from vendors that provide security plans and software bills of materials as required by the PATCH Act.

3. Administrative and Physical Safeguards

  • Staff training and awareness. Educate clinicians and administrative staff on phishing, social engineering and secure telehealth practices. Simulated phishing exercises can reduce click rates. Ensure staff understand how to verify patient identity and handle consent during virtual visits.
  • Privacy during consultations. Encourage providers to conduct telehealth sessions in private rooms and ask patients to do the same. Use headphones and white-noise machines to prevent eavesdropping.
  • Physical device security. Require password or biometric locks on devices used for telehealth, enable remote wipe capabilities, and prohibit sharing work devices with others. When employees work remotely, ensure they use secure home networks or virtual desktop infrastructures.
  • Informed consent and documentation. Obtain and record patient consent for telehealth visits. Document encounters thoroughly and store records securely.


4. Step-by-Step Protocols for Telehealth Visits

The HHS Office for Civil Rights outlines practical steps for maintaining privacy and security before, during and after telehealth appointments:

  1. Before the visit:
    • Perform a risk analysis of telehealth technology and policies.
    • Review your organization’s telehealth policies and procedures; ensure they cover consent, identity verification and data handling.
    • Verify that the platform is HIPAA-compliant; ensure encryption and BAA agreements are in place.
    • Advise patients to use secure, password-protected devices and private rooms.
  2. During the visit:
    • Authenticate both patient and provider identities; ask the patient to show a government-issued ID.
    • Confirm patient location for emergency purposes.
    • Obtain oral or written consent if not already recorded.
    • Use unique meeting links and enable waiting-room features to prevent unauthorized access.
    • Maintain professional standards; avoid discussing patient information where others can overhear.
  3. After the visit:
    • Save documentation securely in the EHR.
    • Communicate follow-up instructions through secure messaging platforms; avoid sending PHI via unencrypted email or consumer texting.
    • Solicit patient feedback to identify usability or privacy concerns.
    • Review sessions internally to ensure policies were followed and update training as needed.


5. Emerging Technologies and Innovations

The future of secure telemedicine lies not only in better policies but also in technological innovation. Fredash Education’s overview of data security innovations in healthcare notes that innovations such as blockchain, artificial intelligence and zero-trust architecture can enhance privacy. Below are promising developments:

  • Blockchain for immutable records. Decentralized ledgers can provide tamper-evident logs of telehealth sessions and consent forms. Each transaction is cryptographically linked, making unauthorized changes detectable.
  • AI-driven threat detection. Machine-learning models can analyze network traffic and user behavior to identify anomalies indicative of phishing or ransomware attacks. However, organizations must guard against AI poisoning.
  • Privacy-enhancing technologies (PETs). Techniques like homomorphic encryption and secure multi-party computation allow data to be processed in encrypted form, reducing exposure.
  • Zero-trust principles. Adopt a mindset where no user or device is trusted by default, whether inside or outside the network. Continuous authentication and authorization enforce least privilege.
  • Federated identity management. Use standards such as OAuth 2.0 and OpenID Connect to provide single sign-on while reducing password fatigue.
  • Augmented reality (AR) and wearable security. As clinicians use AR headsets or smart glasses for remote surgery or instruction, ensure devices are hardened against tampering and that data streams are encrypted.


Implications for Patients and Providers

For healthcare organizations

Hospitals, clinics and telehealth startups must embrace a culture of cyber resilience. Cybersecurity budgets should be tied to patient safety, not just compliance. Leadership must champion security initiatives, allocate resources for training and invest in modern technologies. Incident response plans should be rehearsed regularly, with clear roles and escalation paths. Organizations should participate in threat-sharing networks such as the HHS 405(d) Program and local Health Information Sharing and Analysis Centers (HISACs).


For clinicians

Practitioners are often the first line of defense. Clinicians should:

  • Use approved platforms only and avoid consumer video apps for professional consultations.
  • Verify identity and document consent.
  • Report suspicious emails or system anomalies to IT immediately.
  • Limit use of personal devices; when necessary, ensure the devices are encrypted and protected by strong passwords or biometrics.


For patients

Patients play a role in protecting their own privacy:

  • Secure the environment. Conduct telehealth visits in a private room, use headphones and close browser windows when finished.
  • Verify providers. Confirm that you are speaking with the correct healthcare professional and platform; watch for unexpected requests to re-enter personal information.
  • Use trusted networks. Avoid public Wi-Fi; use a password-protected home network or mobile hotspot. Keep devices updated and protected with antivirus software.
  • Review privacy policies. Understand how your data will be used and ask questions about consent and data retention.
