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...
Blue Cross Blue Shield of Minnesota Starts Correcting 200,000 Critical and Severe Vulnerabilities
Blue Cross Blue Shield of Minnesota, the largest health insurer in the state, is now taking steps to fix around 200,000 unaddressed vulnerabilities on its servers that, in some cases, are more than a decade old. In August 2018, Tom Yardic, a cybersecurity engineer at BCBS Minnesota discovered patches were not being applied on its servers, even though the vulnerabilities were rated critical or severe. The engineer met with executives at BCBS Minnesota to raise the alarm, yet no action appeared to be taken. Around a month later, Yardic alerted the BCBS Minnesota board of trustees as a last resort to get action taken to address the flaws, according to a recent report in the Star Tribune. According to the newspaper report, evidence was obtained that revealed vulnerabilities had not been addressed for many years. There were around 200,000 critical or severe vulnerabilities that had not been addressed on approximately 2,000 servers. Around 44% of the vulnerabilities were more than 3 years old and approximately 12% of the flaws dated back 10 or more years. Approximately 3.9 million...
Truman Medical Centers Notifies 114,466 Patients of Potential PHI Exposure
Truman Medical Centers, the largest provider of inpatient and outpatient services in Kansas City, MO, has discovered the protected health information of 114,466 patients was stored on an unencrypted laptop computer that was stolen from the vehicle of one of its employees. The laptop was protected with a password, but it is possible that the password could be cracked and data on the device accessed. At the time of issuing the notifications, Truman Medical Centers has not uncovered any evidence to suggest that any patient information has been accessed by unauthorized individuals or has been misused. The types of information on the laptop varied from patient to patient and may have included patient names along with one or more of the following types of information: Dates of birth, patient account numbers, medical record numbers, Social Security numbers, health insurance information, and limited medical and treatment information, such as diagnoses, dates of service, and provider names. The theft occurred on July 18, 2019, but it took until October 29, 2019 to determine that patient...
Rep. Jayapal Seeks Answers from Google and Alphabet on Ascension Partnership
Pressure is continuing to be applied on Google and its parent company Alphabet to disclose information about how the protected health information (PHI) of patients of Ascension will be used, and the measures put in place to ensure PHI is secured and protected against unauthorized access. The partnership between Google and Ascension was announced on November 11, 2019 following the publication of a story in the Wall Street Journal. A whistleblower at Google had shared information with the WSJ and expressed concern that millions of healthcare records had been shared with Google without first obtaining consent from patients. It was also alleged that Google employees could freely download PHI. In its announcement, Google stated that the collaboration – named Project Nightingale – involved migrating Ascension’s infrastructure to the cloud and that it was helping Ascension implement G Suite tools to improve productivity and efficiency. Patient data was also being provided to Google to help develop AI and machine learning technologies to improve patient safety and clinical quality....
