CMS Blue Button 2.0 Coding Bug Exposed PHI of 10,000 Medicare Beneficiaries
The Centers for Medicare and Medicaid Services (CMS) has discovered a bug in its Blue Button 2.0 API exposed the protected health information of around 10,000 Medicare beneficiaries. Access to the Blue Button API has been temporarily suspended while the CMS completes a comprehensive code review. The CMS has not produced a timeline for when the Blue Button 2.0 service will be resumed. On December 4, 2019, the CMS was alerted to a data anomaly with the Blue Button API by a third-party application partner. The CMS confirmed the data anomaly and immediately suspended access to the production environment while the matter was investigated. The CMS determined the anomaly was due to a coding bug. That bug potentially allowed data to be shared with incorrect Blue Button 2.0 applications and the wrong beneficiaries. The CMS determined 30 applications have been impacted by the bug. The Blue Button platform is used by Medicare beneficiaries to authorize third-party applications, services, and research programs to access their claims data.

Email Security Breaches Reported by Conway Medical Center and Equinox Inc.
The email accounts of several employees of Conway Medical Center in South Carolina have been accessed by unauthorized individuals. The phishing attack was detected on October 7, 2019 and affected email accounts were immediately secured to prevent further unauthorized access. External cybersecurity experts were engaged to investigate the breach and determine whether patient information had been viewed or acquired. The investigators determined that the first email accounts were compromised in or before July 2019. It took until November 20, 2019 for the investigators to confirm that the protected health information of patients had been exposed as each email had to be checked to determine whether it contained PHI and if it had been accessed. That was largely a manual process. The way the email accounts were accessed meant emails may have synchronized with the attacker’s computer and could have been automatically downloaded. Those emails contained names, addresses, Social Security numbers, dates of birth, phone numbers, dates of admission, discharge dates, CMC account numbers, amount...
Tidelands Health Recovering from Malware Attack
Tidelands Health in Georgetown, SC, is working round the clock to restore its computer systems after the discovery of malware on its network on December 12, 2019. The attack has forced the healthcare provider to shut down parts of its network and implement emergency protocols. Staff have been using paper records for patients while the malware is removed and systems are restored and brought back online. Patients are being seen and quality care is still being provided, although a limited number of non-emergency appointment have had to be rescheduled, according to Tidelands Health spokesperson, Dawn Bryant. The type of malware involved has not been disclosed, although Tidelands Health has said no data was lost and patient information was not compromised. Third-party cybersecurity experts have been engaged to investigate the attack, remove the malware, and restore its systems. That is a time-consuming, methodical process as the stability and integrity of every system must be thoroughly assessed before it is possible to bring each back online.

Poor RSA Encryption Implementation Opens Door to Attacks on Medical Devices and Implants
Encryption renders data inaccessible to unauthorized individuals, provided the private key to decrypt data is not compromised and strong encryption is used. Not all algorithms provide the same level of protection. The strength of encryption relies on the length of the key. The longer the key, the more computational power is required to break the encryption. When strong encryption is used, the computing power and time required to break the encryption renders the data virtually inaccessible. DES was once considered a strong form of encryption but the computing power now available makes cracking the encryption possible even on relatively inexpensive computers. DES used 56-bit keys, which were fine in the 1970’s, but today the keys are nowhere near long enough. Strong encryption today is generally considered to require 256-bit keys, such as those generated by the AES algorithm. With AES-256, for the time being at least, sensitive data can be adequately secured. Providing the key is not disclosed, encrypted data cannot be accessed. RSA is an alternative encryption standard that is...
15 Million Customers Potentially Impacted by Ransomware Attack on Large Canadian Medical Testing Company
A major data breach has been reported by one of Canada’s largest medical testing and diagnostics companies. Toronto-based LifeLabs said hackers have potentially gained access to the personal and health information of up to 15 million customers, most of whom are in British Columbia and Ontario. The number of people potentially affected makes this one of the largest healthcare ransomware attacks to date. The privacy commissioners in both provinces said the scale of the attack “extremely troubling.” After gaining access to its systems, the attackers deployed ransomware and encrypted an extensive amount of customer data. The cyberattack is still under investigation, so it is unclear what, if any, data has been stolen. It has been confirmed that the attackers gained access to parts of the system that contained the test results of around 85,000 Ontarians. The test results were from 2016 and earlier. No evidence has been found to suggest more recent test results, or medical test results from customers in other areas, have been compromised. Some of those test results include highly...
