An extortion feed is an online platform or website, often maintained by cybercriminal groups, where details about their victims are published to coerce payment. These feeds typically list companies or individuals who have refused to pay ransoms after a cyberattack, such as ransomware incidents. By publicizing sensitive data or threatening to release confidential information, attackers increase pressure on victims to comply with their demands. Extortion feeds are part of the 'double extortion' tactic, where criminals threaten both to encrypt data and to leak it publicly. Security teams monitor these feeds to assess exposure and respond to threats.
