The login credentials of some staff members of the World Health Organization were accessed by hackers in March 2020. The compromised passwords contained access to a lot of sensitive information about the pandemic. The attack was the result of a successful phishing attempt that forced the organization to switch the infrastructure as a future precautionary step.

The Ryuk ransomware gang, active between 2018 and mid-2020, targeted organizations across various sectors, including healthcare during the Covid pandemic. The gang was responsible for numerous attacks, causing significant disruptions and financial losses. The recent extradition of a 33-year-old member of the Ryuk operation to the United States highlights the continued efforts to bring cybercriminals to justice. The gang's rebranding to Conti and subsequent splintering into smaller groups underscores the evolving threat landscape.
