WASHINGTON, Oct 31 (Reuters) - The White House will host officials from 37 countries and 13 global companies in Washington this week to address the growing threat of ransomware and other cyber crime, including the illicit use of cryptocurrencies, a senior U.S. official said. The White House hopes the meeting will allow participating countries to "institute a set of cyber norms that are recognized across the globe to counter criminal ransomware threats and hold malicious actors accountable," the official said. One key topic for discussion will be how to disrupt such attacks, counter the illicit movement of cryptocurrencies and build resilience against such attacks, the official said. Top administration officials, including FBI Director Chris Wray, Deputy Treasury Secretary Wally Adeyemo, White House national security adviser Jake Sullivan and Deputy Secretary of State Wendy Sherman will address the meeting. Companies participating include Crowdstrike, Mandiant, Cyber Threat Alliance, Microsoft, Cybersecurity Coalition, Palo Alto, Flexxon, SAP, Institute for Security + Technology, Siemens, Internet 2.0, Tata – TCS, and Telefonica, the White House said.
