Phishing Attack Impacts Saint Alphonsus Health System and Saint Agnes Medical Center Patients

A phishing attack on Saint Alphonsus Health System in Boise, ID has resulted in the exposure of patient information and has also impacted patients of Saint Agnes Medical Center in Fresno, CA.

Saint Alphonsus identified unusual activity in an employee’s email account on January 6, 2021. The account was immediately secured, and an investigation was conducted to determine the source and nature of the activity. Saint Alphonsus determined that the account had been accessed by an unauthorized individual on January 4, 2021, giving the individual access to the account and information contained therein for 2 days. The account was used to send phishing emails to other individuals in an attempt to obtain usernames and passwords.

The employee whose credentials were compromised assisted with certain business functions that required access to protected health information, including performing billing functions for the West Region of Trinity Health, which includes Fresno.

A review of all emails and attachments revealed the account contained the protected health information of certain patients. The PHI in the account varied from patient to patient and included full names in combination with one or more of the following data elements: Address, telephone, date of birth, email, medical record number, treatment information, and/or billing information. The account also contained a limited number of Social Security numbers and credit card numbers.

While unauthorized account access was confirmed, it was not possible to determine which emails, if any, had been accessed. At the time of issuing notifications, no evidence was found to indicate any patient information has been misused. Credit monitoring services are being offered to affected individuals and employees have received further training on email and cybersecurity to prevent similar breaches in the future.

It is not currently known how many patients have been affected by the breach. This post will be updated when further information becomes available.

4,122 Individuals Affected by Southeastern Minnesota Center for Independent Living Phishing Attack

Southeastern Minnesota Center for Independent Living (SEMCIL), a provider of disability and support services in Rochester and Winona, has discovered an unauthorized individual gained access to an employee’s email account that contained the protected health information of 4,122 individuals.

Up to 100,000 Individuals Affected by Cochise Eye and Laser Ransomware Attack

The Sierra Vista, AZ-based ophthalmology and optometry provider Cochise Eye and Laser experienced a ransomware attack on January 13, 2021 that resulted in the encryption of its patient scheduling and billing software.

The attack prevented Cochise Eye and Laser from accessing any data in its scheduling system. Eye care services continued to be provided to patients, with the practice reverting to using paper charts. According to a February 17, 2021 breach notice on its website, paper charts were still in use as the scheduling system remained out of action.

The investigation into the ransomware attack found no evidence to indicate any patient data were exfiltrated prior to the encryption of files; however, data theft could not be ruled out. The types of information potentially accessed by the attackers included names, dates of birth, addresses, phone numbers and, for some individuals, Social Security numbers.

Since the attack, Cochise Eye and Laser has been working on improving the security of its systems and is implementing a new offsite backup system. Efforts to recover the encrypted data are ongoing and patient charts will be used to rebuild its schedules.

The ransomware attack has been reported to the HHS’ Office for Civil Rights as affecting up to 100,000 patients.

Petersburg Medical Center Discovers Insider Privacy Breach

Petersburg Medical Center in Alaska has discovered an employee accessed the medical records of certain patients without authorization, when there was no legitimate work reason for doing so.

An internal investigation was launched as soon as the unauthorized access was discovered, and the medical center was satisfied that there have been no further disclosures by the employee and no patient information was removed from the medical center.

Following the breach, the medical center took steps to prevent the employee “from accessing any patient records now or in the future.” It is unclear whether the sanctions included termination. Steps have since been taken to prevent any further privacy violations at the medical center and affected individuals have been notified by mail.

Tens of Thousands of Individuals Affected by AllyAlign Health Ransomware Attack

AllyAlign Health, a Glen Allen, VA-based Medicare Advantage health plan administrator, has started notifying members and providers about an attempted ransomware attack that occurred on November 13, 2020.

According to the breach notification letters sent to affected individuals, AllyAlign Health first became aware of the attack on November 14, 2020. An investigation of the incident found the systems accessed by the attackers contained members’ first and last names, addresses, dates of birth, Social Security numbers, Medicare health insurance claim numbers, Medicare beneficiary identifiers, medical claims histories, health insurance policy numbers, and other medical information.

Providers affected by the breach have been notified that names, addresses, dates of birth, Social Security numbers, and Council for Affordable Quality Healthcare (CAQH) credentialing information may have been compromised.

It is unclear exactly how many individuals have been affected by the incident. According to the breach notification sent to the Maine Attorney General, the protected health information of 76,348 individuals was potentially compromised in the breach. The breach report submitted to the Department of Health and Human Services’ Office for Civil Rights indicates 33,932 individuals have been affected. The 33,932 individuals could be members and the rest providers.

The Attorney General notification indicates the breach was discovered on February 2, 2021. This could be the date when the breach investigation was completed, and the number of individuals affected became known.

AllyAlign Health said it acted quickly to respond to the breach and engaged IT specialists to ensure the security of its network environment. Since the breach occurred, policies and procedures have been updated relating to the security of its systems and servers and information life cycle management.

IBM X-Force: Healthcare Cyberattacks Doubled in 2020

A new report from IBM X-Force shows healthcare cyberattacks doubled in 2020 with 28% of attacks involving ransomware. The massive increase in healthcare industry cyberattacks saw the sector rise from last place to 7th, with the finance and insurance industry the most heavily targeted, followed by manufacturing, energy, retail, professional services, and government. Healthcare accounted for 6.6% of cyberattacks across all industry sectors in 2020.

The 2021 X-Force Threat Intelligence Index report was compiled from monitoring data from over 130 countries and included data from more than 150 billion security events a day, with the data gathered from multiple sources including IBM Security X-Force Threat Intelligence and Incident Response, X-Force Red, IBM Managed Security Services, and external sources such as Intezer and Quad9.

The most common way networks were breached was the exploitation of vulnerabilities in operating systems, software, and hardware, which accounted for 35% of all attacks up from 30% in 2019. This was closely followed by phishing attacks, which were the initial entry point in 33% of attacks, up from 31% in 2019.

2020 was the first year since IBM X-Force started publishing its annual threat index reports that the exploitation of vulnerabilities was more common than phishing as the initial attack vector, which was largely due to the global shift to a distributed workforce in response to the pandemic.

Around 1 in 5 cyberattacks in 2020 involved the exploitation of vulnerabilities in Citrix servers, which were used to support remote workforces. Out of all attacks involving the exploitation of Citrix vulnerabilities, healthcare placed third with 17% of all attacks. Credential theft-related attacks secured third place in the initial attack vector list and accounted for 18% of attacks, down from 29% in 2019.

In healthcare especially, ransomware attacks increased sharply. Overall, 23% of security events in 2020 involved ransomware, up from 20% in 2019. 28% of all cyberattacks on the healthcare industry involved ransomware. These attacks often involved data theft prior to file encryption to pressure victims into paying the ransom to prevent the exposure or sale of stolen data. 59% of ransomware attacks in 2020 involved the use of this double-extortion tactic.

Sodinokibi was used in 22% of all ransomware attacks. The researchers estimate that the Sodinokibi gang generated $123 million in ransom payments in 2020. Other highly active ransomware operations included RagnarLocker, Netwalker, Maze, and Ryuk, which each had a share of 7% of the attacks.

Ransomware was the leading attack type, followed by data theft, and server access. Data theft increased 160% year-over-year, with a large proportion of the attacks due to the Emotet Trojan. Server access increased 233% in the past 12 months, mostly involving the exploitation of vulnerabilities and the use of stolen credentials. Remote Access Trojan (RAT) attacks had a notable increase from 2% of attacks in 2019 to 6% in 2020. Business email compromise attacks decreased in 2020, falling from 14% of attacks in 2019 to 9% in 2020. Insider breaches fell from 6% to 5% of attacks, with misconfigurations unchanged, accounting for 5% of attacks.

The second and third most common types of healthcare cyberattacks were server access and BEC attacks, each accounting for 18% of attacks in 2020. Data theft, insider incidents, and misconfigurations accounted for 9% of attacks each.

The increase in healthcare industry cyberattacks was largely due to the industry being heavily targeted by ransomware gangs and threat actors targeting COVID-19-related research organizations. It could have been far worse for the healthcare industry. Security researchers became aware that the Ryuk ransomware gang was planning a targeted campaign in October that would have seen 400 hospitals attacked. Fortunately, efforts by cybersecurity companies and law enforcement limited the attacks to just 9 out of the 400 hospitals.

Roundup of Recent Healthcare Phishing and Malware Incidents

A round up of recent healthcare privacy breaches that have been reported to the HHS’ Office for Civil Rights and state Attorneys General recently.

Twelve Oaks Recovery Discovers Malware Infection and Data Theft

Twelve Oaks Recovery, a Navarre, FL-based addiction and mental health treatment center, has discovered an unauthorized individual gained access to its network, installed malware, and stole documents from its systems. The attack was detected on December 13, 2020 when unusual network activity was detected. A forensic investigation confirmed malware had been deployed on December 13, and the following day data exfiltration was confirmed.

A review of the documents obtained by the attacker revealed they contained the protected health information of 9,023 patients, and included names, addresses, dates of birth, medical record numbers, and Social Security numbers.

Twelve Oaks Recovery has enhanced its network monitoring tools and taken steps to prevent similar breaches from occurring in the future.

Rainbow Rehabilitation Centers Discovers Email Account Breach

Rainbow Rehabilitation Centers, a Livonia, MI-based provider of therapeutic rehabilitation services for individuals with brain and spinal cord injuries, has discovered an unauthorized individual gained access to an employee’s email account that contained the protected health information of 1,749 patients and information about its employee group health plans.

Third party forensic experts were engaged to investigate the breach and confirmed that a single email account was breached. A review of the account revealed it contained PHI such as names, social security numbers, driver’s license numbers, appointment scheduling notes, and medical plan and benefits enrollment information. It was not possible to determine if any of that information was accessed by the attacker, but no reports have been received that suggest any patient information has been misused.

Affected individuals have been notified and offered a complementary 12-month membership to credit monitoring and identity theft protection services.

Summit Behavioral Healthcare Email Accounts Compromised

Summit Behavioral Healthcare, a Brentwood, TN-based provider of behavioral health services and operator of 18addition treatment centers throughout the United States, has discovered two employee email accounts were compromised, starting in late May 2020.

A third-party digital forensics firm was engaged to investigate the breach and on January 21, 2021 it was confirmed that protected health information was contained in the compromised accounts and may have been accessed or obtained by unauthorized individuals.

The information in the accounts varied from individual to individual and may have included names in combination with one or more of the following types of data: Social Security number, diagnosis or symptom information, treatment information, prescription information, health insurance numbers, medical history, financial account information, Medicaid / Medicare identification numbers, and health care provider information.

Affected individuals have been notified and offered a complementary 12-month membership to credit monitoring and identity theft protection services.

Email Account Breach Discovered at Jacobson Memorial Hospital and Care Center

Jacobson Memorial Hospital and Care Center in Elgin, ND has discovered an email account containing the protected health information of 1,547 patients has been accessed by an unauthorized individual.

The breach was detected on or around August 5, 2020 and a third-party cybersecurity firm was hired to investigate the breach and determine if any information had been accessed. It appears that the attack was conducted in order to send spam emails from the account; however, it is possible that patient information was viewed.

The account contained names, addresses, dates of birth, email addresses, Social Security numbers, phone numbers, insurance policy numbers, credit card numbers, bank account numbers, and some health information.

A new facility-wide security system has now been implemented, policies and procedures have been updated, and additional training has been provided to staff and vendors on data protection. Affected individuals have been offered complementary credit monitoring and identity theft restoration services.

Kaiser Permanente Fires Employee for Inappropriate PHI Access

Kaiser Permanente has fired an employee for accessing members’ medical records without authorization. The privacy breach was detected on December 28, 2020 and the investigation confirmed the records were accessed for reasons unrelated to individuals’ healthcare service needs. The types of information in the records included names, addresses, telephone numbers, email addresses, dates of birth, and photographs, but no other sensitive information.

Kaiser Permanente is reviewing its policies and procedures and will be implementing additional safeguards, as appropriate, to prevent similar privacy breaches in the future.

Universal Health Services Ransomware Attack Cost $67 Million in 2020

2020 was a particularly bad year for healthcare industry ransomware attacks, with one of the worst suffered by the King of Prussia, PA-based Fortune 500 healthcare system, Universal Health Services (UHS).

UHS, which operates 400 hospitals and behavioral health facilities in the United States and United Kingdom, suffered a cyberattack in September 2020 that wiped out all of its IT systems, affecting its hospitals and other healthcare facilities across the country.

The phone system was taken out of action, and without access to computers and electronic health records, employees had to resort to pen and paper to record patient information. In the early hours after the attack occurred, the health system diverted ambulances to alternative facilities and some elective procedures were either postponed or diverted to competitors. Patients reported delays receiving test results while UHS recovered from the attack.

UHS worked fast to restore its information technology infrastructure following the attack and worked around the clock to return to normal business operations; however, the recovery process took around 3 weeks. The disruption naturally had a major impact financially, with the UHS quarterly earnings report for Q4, 2020 showing $42.1 million in losses, which equated to 49 cents per diluted share. UHS ended the quarter with profits of $308.7 million, up 6.6% from Q4, 2019.

Restoring its IT infrastructure resulted in significant increase in labor costs, both internally and externally. Cash flows were also affected as certain administrative functions such as coding and billing had to be delayed until December 2020.

UHS has reported total pre-tax losses of an estimated $67 million in 2020 due to the ransomware attack, mostly as a result of the loss of operating income, reduction in patient activity, and increased revenue reserves as a result of the billing delays. UHS believes it is entitled to recover the majority of the $67 million in insurance payouts.

Gore Medical Management Alerted to 2017 Breach 79,100 Patients’ PHI

Gore Medical Management, a medical practice company based in Griffin, GA, has discovered a historic data breach involving the protected health information (PHI) of 79,100 individuals. The breach occurred in 2017 and affects patients of Family Medical Center in Thomaston, which is now part of Upson Regional Medical Center.

In November 2020, Gore Medical Management was informed by the Federal Bureau of Investigation that a third-party computer had been recovered as part of an investigation which was found to contain the PHI of Family Medical Center patients.

The breach investigation confirmed that the vulnerability exploited by the hacker to gain access to the Family Medical Center network had been identified and corrected a few months after the breach, although the breach itself was not detected at the time. The medical record system was not compromised, but files containing names, addresses, dates of birth, and Social Security numbers were exfiltrated. No financial information or healthcare records were involved.

There does not appear to have been further access of its systems or any other transfers of data since 2017. Gore Medical Management has now notified all affected patients and has offered them a 12-month membership to an identity theft protection and credit monitoring service.

Pennsylvania Adult & Teen Challenge Discovers Compromised Email Accounts Containing PHI of 7,771 Individuals

Pennsylvania Adult & Teen Challenge, a Rehrersburg, PA-based provider of addiction treatment programs for adults and young people, has discovered an unauthorized individual gained access to employee email accounts that contained the protected health information of 7,771 individuals.

Suspicious activity was detected in an email account on July 29, 2020 and steps were taken to prevent further access and investigate the breach. The investigation confirmed that certain email accounts had been accessed by an unauthorized individual between July 27, 2020 and July 30, 2020.

A forensic investigation was conducted, and the compromised accounts were reviewed to determine the information potentially obtained by the attacker. That process was completed on December 29, 2020.

The types of information in the accounts varied from individual to individual and may have include names along with one or more of the following data elements: Social Security Number, driver’s license number, financial account information, payment card information, date of birth, prescription information, diagnosis information, treatment information, treatment provider, health insurance information, medical information, Medicare/Medicaid ID number, employer identification number, electronic signature, username and password.

It was not possible to determine if information in the email accounts was accessed or exfiltrated, but no reports have been received to date to indicate any patient information has been misused. Notification letters have recently been sent to affected individuals and complimentary identity theft protection services have been offered.
