Majority of Microsoft 365 Admins Have Not Enabled Multi-Factor Authentication
A new report published by CoreView has revealed the majority of Microsoft 365 admins have not enabled multi-factor authentication to protect their accounts from unauthorized remote access and are failing to implement other basic security practices. According to the study, 78% of Microsoft 365 administrators have not activated multi-factor authentication and 97% of Microsoft 365 users are not using MFA. “This is a huge security risk – particularly during a time where the majority of employees are remote – that IT departments must acknowledge and address in order to effectively deter cyberattacks and strengthen their organization’s security posture,” explained the researchers. The SANS Institute says 99% of data breaches can be prevented by using MFA, while Microsoft explained in an August 2020 blog post that MFA is the single most important measure to implement to prevent unauthorized account access, explaining that 99.9% of account breaches can be prevented by using MFA. The CoreView study also revealed 1% of Microsoft 365 admins do not use strong passwords, even though hackers are...
Sky Lakes Medical Center and St. Lawrence Health System Attacked with Ransomware
Two more hospitals have experienced ransomware attacks that have taken their computer systems offline and have forced clinicians to switch to pen and paper to record patient information. Both ransomware attacks occurred on Tuesday, October 27, 2020, one on Sky Lakes Medical Center in Klamath Falls, OR and the other on St. Lawrence Health System in New York. Both attacks involved Ryuk ransomware. Sky Lakes Medical Center announced on Facebook that while its computer systems had been taken out of action, care continued to be provided to patients and its emergency and urgent care departments remained open and fully operational and most scheduled elective procedures were continuing as planned. At this stage, no evidence has been found to indicate any patient data were compromised in the attack; however, the investigation is still in the early stages. The attack on St. Lawrence Health System was detected several hours after the initial compromise. St. Lawrence Health System issued a statement saying its IT department had taken systems offline in an effort to contain the attack and...
Advisory Warns of Targeted Ryuk Ransomware Attacks on the Healthcare and Public Health Sector
The Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), and the Department of Health and Human Services (HHS) have issued an advisory warning about increased Ryuk ransomware activity targeting the healthcare and public health sector. Credible evidence has been obtained indicating an increased and imminent threat to hospitals and healthcare providers in the United States. The advisory details some of the tactics, techniques, and procedures (TTPs) used by the operators of Ryuk ransomware and other cybercriminal groups who are assisting with the distribution of the ransomware to help the healthcare sector manage risk and protect their networks from attacks. The advisory explains that Ryuk ransomware is commonly delivered as a secondary payload by the TrickBot Trojan. TrickBot is a banking Trojan that was first identified in 2016 and has since been updated with a host of new functions. In addition to stealing banking credentials, TrickBot is capable of mail exfiltration, cryptomining, data exfiltration from point of sale systems, and acts as...
Aetna Hit with $1 Million HIPAA Fine for Three Data Breaches
Aetna Life Insurance Company and the affiliated covered entity (Aetna) has agreed to settle multiple potential HIPAA violations with the Department of Health and Human Services’ Office for Civil Rights (OCR) that were discovered during the investigation of three data breaches that occurred in 2017. The first of those data breaches was reported to OCR in June 2017 and concerned the exposure of the protected health information (PHI) of health plan members over the Internet. Two web services were used to display health plan-related documents to its members, but those documents could be accessed over the Internet without the need for any login credentials. The lack of authentication allowed the documents to be indexed by search engines and displayed in search results. Aetna’s investigation revealed the PHI of 5,002 individuals had been exposed, which included names, insurance identification numbers, claim payment amounts, procedures service codes, and dates of service. The second two HIPAA breaches involved the exposure and impermissible disclosure of highly sensitive information in...
Sonoma Valley Hospital Suffers Significant EHR Downtime Event
Sonoma Valley Hospital in California experienced a computer security incident on October 11, 2020 which took its computer systems offline and caused “a significant downtime event.” The hospital implemented its business continuity plan which allowed care to continue to be provided to patients while its computer systems were out of action. Throughout the incident its emergency department remained open and elective and necessary surgeries continued to be performed. The majority of diagnostic services continued without interruption, although the incident did cause disruption for some patients. The patient portal has remained available throughout, although new results have not been posted since October 11. An investigation into the incident was immediately launched and third-party cybersecurity experts were engaged to assist with the investigation and recovery efforts. In a December 8, 2020 letter to patients, the hospital explained that patient data may have been compromised during the attack. The letter confirms ransomware was used to encrypt files in an attempt to extort money from...
