Data on Pastebin was exposed by the infamous black hat hacker CyberZeist, who gained access to the FBI website FBI.gov.
Account information, including names, SHA1 encrypted passwords, SHA1 salts, and emails, are contained in leaked documents.
While professionals at the FBI worked to resolve the issue, the expert provided more details about the attack.
The website administrators appear to have made some unfortunate mistakes. For instance, they left backup files on the same server, which allowed hackers to access them even if they chose not to publish them right away.
