Since the onset of the COVID-19 pandemic, hospitals, and healthcare facilities have dealt with a deluge of cyberattacks, and ransomware has been especially pernicious. According to the U.S. Cybersecurity and Infrastructure Security Agency (CISA), hackers infiltrated many of these organizations using stolen credentials obtained from a known vulnerability in their Pulse Secure VPN servers.
This threat was first identified in October 2019, with the CISA and the US Federal Bureau of Investigation both issuing subsequent alerts in January and April of 2020. Unfortunately, even after repairing the vulnerability, the agencies have seen examples of cybercriminals using compromised credentials to access company networks.
The incident is a reminder of the importance of acting swiftly to address cybersecurity vulnerabilities but also of maintaining insights into the Dark Web, where stolen login information can quickly circulate and create chaos for your IT infrastructure.
COVID-19 is creating a more perilous digital environment for companies, making now the right time to double-down on cybersecurity initiatives that can prevent a breach.
