CISA Publishes Voluntary Cybersecurity Performance Goals for Critical Infrastructure Organizations
A set of cross-sector Cybersecurity Performance Goals (CPGs) have been published by the Cybersecurity and Infrastructure Security Agency (CISA) for critical infrastructure organizations to adopt to help them achieve a minimum standard of cybersecurity and better protect their networks and systems from attacks that threaten their ability to operate. In response to the May 2021 ransomware attacks on the oil pipeline system operator, Colonial Pipeline, and the food processing firm JBS, President Biden signed an Executive Order on Improving the Nation’s Cybersecurity. As part of that initiative, President Biden signed the National Security Memorandum on Improving Cybersecurity for Critical Infrastructure Control Systems on July 28, 2021, which called for CISA to publish a baseline set of CPGs with the aim of improving the cybersecurity of all critical infrastructure in the United States on which Americans depend. According to CISA, the CPGs are “a prioritized subset of IT and operational technology (OT) cybersecurity practices that critical infrastructure owners and operators can...
PHI of Almost 34,000 Patients Potentially Compromised in Michigan Medicine Phishing Attack
University of Michigan Health (Michigan Medicine) has recently announced that the protected health information of approximately 33,850 patients has potentially been compromised in a phishing attack. Suspicious activity was detected within its email environment and steps were immediately taken to secure the accounts to prevent further unauthorized access. Michigan Medicine said it was targeted in a phishing campaign between August 15 and August 23, 2022, and four email accounts were compromised. Michigan Medicine said in its breach notice that employee email accounts were protected with multi-factor authentication at the time of the attack. Four employees responded to the phishing emails, visited a malicious website, disclosed their Michigan Medicine login information, and responded to the multi-factor authentication prompts, which allowed their accounts to be accessed. The forensic investigation found no evidence of data theft and it appeared that the accounts were not compromised in order to obtain patient information; however, Michigan Medicine has assumed that all information in...
Adoption of Passwordless Authentication Grows But Poor Password Practices Persist
Passwords are an inexpensive and convenient form of authentication. While passwords can provide a high degree of protection, in practice they are a weak point that is commonly exploited by threat actors to gain access to internal networks and sensitive data. Brute force attacks are conducted to guess weak passwords, credential stuffing attacks succeed because people reuse passwords on multiple platforms, and employees divulge their passwords by responding to phishing emails. Many of these attacks targeting passwords succeed because employees engage in risky password practices, such as setting easy-to-remember passwords or using the same password for multiple accounts. Businesses can take steps to eliminate these bad password practices by providing security awareness training to teach employees password best practices, enforcing password complexity rules, and providing a password manager; however, risk can only be reduced, not eliminated entirely. Employees will make mistakes, and some will circumvent the rules. The best approach for businesses to eliminate password risks is to do...
Only One in Five Organizations Follow the 3-2-1 Rule for Data Backups
The healthcare industry is an attractive target for cybercriminals and data thieves. Healthcare organizations store vast amounts of sensitive data that can be easily monetized. Large health systems are often targeted due to the high ransoms that can be demanded, as the recent attack on CommonSpirit Health demonstrated; however, attacks are conducted on healthcare organizations of all sizes. The ransomware remediation firm, Coveware, reported earlier this year that 82% of ransomware attacks in 2021 occurred at firms with fewer than 1,000 employees. Healthcare providers are heavily reliant on access to data, which makes them a prime target for ransomware gangs. When data is rendered unavailable, that naturally has an impact on business operations and causes considerable financial losses, and threatens patient safety. Without access to EHRs and medical histories, healthcare organizations are left with little alternative but to cancel appointments. Fast recovery of data is essential, which is why many healthcare organizations choose to pay the ransom to try to accelerate the data...
California Appellate Court Confirms Trial Court’s Decision to Toss Class Action Insider Breach Lawsuit
A Californian appellate court has recently confirmed the decision of the lower court to deny class action status for a lawsuit filed against a Californian healthcare provider over an insider data breach that affected 5,485 patients. In May 2018, the healthcare provider – Muir Medical Group IPA – discovered a former employee had accessed and copied the records of patients before leaving employment and took patient information to her new employer. The investigation determined the breach occurred in December 2017 and affected patients who received treatment between November 2013 and February 2017. The information copied by the employee included names, contact information, treatment information, and other sensitive data. A lawsuit was filed in the wake of the breach – Vigil v. Muir Medical Group IPA, Inc. – that alleged negligence and violations of the Confidentiality of Medical Information Act (CMIA), the Customer Records Act, and unlawful business practices under the Unfair Competition Law. The lawsuit also alleged violations of the Security Management Process...
