According to a new report, in 2020 2,400 U.S.-based healthcare facilities, local governments, schools, and other institutions were victims of ransomware—a form of cyber-attack in which a hacker holds a person's data hostage and demands a ransom to permit them to access it again. Ransomware has become such a problem that in October the U.S. State Department formed a new office to confront it, and in November the Treasury Department announced that it will partner with its Israeli counterpart on a joint task force to address this and other cybersecurity issues.

Israel, like America, is also confronted with problems in cyberspace. On this week's podcast, Annie Fixler, the deputy director of the Center on Cyber Technology and Innovation at the Foundation for Defense of Democracies, joins Mosaic editor Jonathan Silver to explain the threats that cyber warfare poses to American life, and the role that Israel could play in helping secure both countries from malicious attacks, whether they come from lone-wolf hackers or enemy nation-states.
