The FBI has published a (TLP:WHITE) FLASH message providing indicators associated with the Netwalker Ransomware. The FBI states it has received notifications of Netwalker ransomware attacks on U.S. and foreign government organizations and private companies, among other entities, by unidentified cyber actors. It notes Netwalker became widely recognized in March following intrusions into an Australian transportation and logistics company. The FBI observes that the cyber actors using Netwalker have since taken advantage of the COVID-19 pandemic to compromise an increasing number of unsuspecting victims. In addition to further describing this ransomware and providing technical indicators, this message also includes a list of recommended mitigation measures.
