The White House is hosting three dozen nations and the European Union over the next two days at the 2nd International Counter Ransomware Initiative.
The summit follows a series of high-profile attacks in recent weeks against the Los Angeles Unified School District and CommonSpirit Health.
A number of top administration officials are scheduled to attend, including FBI Director Christopher Wray, Deputy Secretary of State Wendy Sherman, Deputy Treasury Secretary Wally Adeyemo, national security advisor Jake Sherman and Anne Neuberger, deputy national security advisor for cyber and emerging technologies.
A number of major cybersecurity and technology companies are also set to attend, including Google Cloud's Mandiant, Microsoft, CrowdStrike, Palo Alto Networks, SAP, Siemens, and the Cyber Threat Alliance.
The confab is a followup to the virtual ransomware summit hosted by the White House in October 2021.
The Biden administration led the original gathering in an effort to foster international cooperation against the illicit use of money laundering and cryptocurrency trading, which has been the favored payment mechanism for ransomware gangs.
