US Patent 11856007 Defanging malicious electronic files based on trusted user reporting

A system and a method are disclosed for determining that a first electronic communication, received in a first private repository of a user, has been identified (e.g., flagged) as including a threat, and determining a probability that the first electronic communication includes the threat. In response to determining that the probability exceeds a threshold probability, the system monitors monitoring for a second electronic communication, received in a second private repository, that includes contents that match the contents of the first electronic communication. In response to, based on the monitoring, identification of the second electronic communication, the system generates a copy of the second electronic communication to an administrative private repository of an administrator, edits the copy to remove a portion that is likely to include the threat, inserts the copy of the second electronic communication to the second private repository, and deletes the second electronic communication from the second private repository.
