NSA Cybersecurity Guidance for Teleworkers and Other Useful COVID-19 Threat Resources
The National Security Agency has issued cybersecurity guidance for teleworkers to help improve security when working remotely. The guidance has been released primarily for U.S. government employees and military service members, but it is also relevant to healthcare industry workers providing telehealth services from their home computers and smartphones. There are many consumer and enterprise-grade communication solutions available and the cybersecurity protections offered by each can differ considerably. The guidance document outlines 9 important considerations when selecting a collaboration service. By assessing each service against the 9 criteria, remote workers will be able to choose the most appropriate solution to meet their needs. The NSA strongly recommends conducting high-level security assessments to determine how the security capabilities of each platform performs against certain security criteria. These assessments are useful for identifying risks associated with the features of each tool. The guidance document also provides information on using the collaboration...
Advice for Healthcare Organizations on Preventing and Detecting Human-Operated Ransomware Attacks
Human-operated ransomware attacks on healthcare organizations and critical infrastructure have increased during the COVID-19 pandemic. Dozens of attacks have occurred on healthcare organizations in recent weeks, including Parkview Medical Center, ExecuPharm, and Brandywine Counselling and Community Services. Many ransomware attacks are automated and start with a phishing email. Once ransomware is downloaded, it typically runs its encryption routine within an hour. Human-operated ransomware attacks are different. Access is gained to systems several weeks or months before ransomware is deployed. During that time, the attackers obtain credentials, move laterally, and collect and exfiltrate data before encrypting files with ransomware. The attackers can lay dormant in systems for several months before choosing their moment to deploy the ransomware to maximize the disruption caused. The COVID-19 pandemic is the ideal time for the deployment of ransomware on healthcare organizations and others involved in the response to COVID-19, as there is a higher probability that the ransom will be...
EFF Warns of Privacy and Security Risks with Google and Apple’s COVID-19 Contact Tracing Technology
The contact tracing technology being developed by Apple and Google to help track people who have come into close contact with individuals confirmed as having contracted COVID-19 could be invaluable in the fight against SARS-CoV-19; however, the Electronic Frontier Foundation (EFF) has warned that in its current form, the system could be abused by cybercriminals. Google and Apple are working together on the technology, which is expected to be fully rolled out next month. The system will allow app developers to build contact tracing apps to help identify individuals who may have been exposed to SARS-CoV-2. When a user downloads a contact tracing app, each time they come into contact with another person with the app installed on their phone, anonymous identifier beacons called rolling proximity identifiers (RPIDs) will be exchanged via Bluetooth Low Energy. How Does the Contact-Tracing System Work? RPIDs will be exchanged only if an individual moves within a predefined range – 6 feet – and stays in close contact for a set period of time. Range can be determined by strength of...
Ransomware Attackers Claim Three More Healthcare Victims
Parkview Medical Center in Pueblo, Colorado is recovering from a ransomware attack that started on April 21, 2020. The attack resulted in several IT systems being taken out of action, including its Meditech electronic medical record system, which has been rendered inoperable. The attack is currently being investigated and assistance is being provided by a third-party computer forensics firm. Parkview Medical Center is currently working around the clock to bring its systems back online and recover the encrypted data. In the meantime, medical services continue to be offered to patients, who remain the number one priority. Staff have switched to pen and paper to record patient information until systems can be brought back online. Despite not having access to important systems, the medical center says the level and quality of care provided to patients has not changed. A spokesperson for the medical center said, “While our medical staff continue to work around the clock in response to the ongoing global pandemic, we are doing everything in our power to bring our systems back online as...
CloudHealth Creates Optimization Desk to Help Customers During the COVID-19 Pandemic
The uncertainty caused by the COVID-19 pandemic has made optimizing cloud resources a challenge. During uncertain times it is difficult to determine what is required in terms of Reserved Instances or Savings Plans. Businesses that make too great a commitment will end up paying for resources that are not fully utilized and erring on the side of caution could result in having to pay for On-Demand resources at a much greater cost. The uncertainty has also been reflected in AWS spot instance market, which has been particularly volatile during the pandemic and seen large fluctuations in costs. The pandemic has also caused volatility in the currency markets which can also impact cloud bills and change reservation buying strategies. The changes in working practices that the pandemic has forced, has also seen a major rise in demand for remote productivity tools, which complicates cloud resource optimization further. To help customers optimize their cloud infrastructure correctly and keep their cloud costs down during these uncertain times, CloudHealth has launched a new Optimization Desk....
