The document describes the tracking of an anabolic steroid manufacturer who was being investigated by the Drug Enforcement Administration (DEA). The document alleges that the majority of those engaged in the trade in anabolic steroids use Hushmail to communicate.
The DEA agents received three CDs of decrypted emails which contained decrypted emails for the targets of the investigation that had been decrypted as part of a mutual legal assistance treaty between the United States and Canada.
The news will be embarrassing to the company, which has made much of its ability to ensure that emails are not read by the authorise, including the FBI's Carnivore email monitoring software.
"Hushmail's security cannot be broken or weakened by this government sponsored snooping software," the company states.
"The only way to decrypt or unscramble Hush messages is by using your passphrase when you open up your Hushmail account. Carnivore cannot decrypt your mail, and is therefore, powerless against messages sent between Hush users."
