from "David". According to Barnhart, the main points of the email messages were that the TrueCrypt Foundation was "happy with the audit, it didn't spark anything", and that the reason for the announcement was that "there is no longer interest [in maintaining the project]." According to a study released 29 September 2015, TrueCrypt includes two vulnerabilities in the driver that TrueCrypt installs on Windows systems allowing an attacker arbitrary code execution and privilege escalation via DLL hijacking. In January 2016, the vulnerability was fixed in VeraCrypt, but it remains unpatched in TrueCrypt's unmaintained installers. Legal cases Operation Satyagraha In July 2008, several TrueCrypt-secured hard drives were seized from Brazilian banker Daniel Dantas, who was suspected of financial crimes. The Brazilian National Institute of Criminology (INC) tried unsuccessfully for five months to obtain access to his files on the TrueCrypt-protected disks. They enlisted the help of the FBI, who used dictionary attacks against Dantas' disks for over 12 months, but were still unable to decrypt them. United States v. John Doe In 2012 the United States 11th Circuit Court of Appeals ruled that a John Doe TrueCrypt user could not be compelled to decrypt several of his hard drives. The court's ruling noted that FBI forensic examiners were unable to get past TrueCrypt's encryption (and therefore were unable to access the data) unless Doe either decrypted the drives or gave the FBI the password, and the court then ruled that Doe's Fifth Amendment right to remain silent legally prevented the Government from making him or her do so. David Miranda On 18 August 2013 David Miranda, partner of journalist Glenn Greenwald, was detained at London's Heathrow Airport by Metropolitan Police while en route to Rio de Janeiro from Berlin. He was carrying with him an external hard drive said to be containing sensitive documents pertaining to the 2013 global surveillance disclosures sparked by Edward Snowden. Contents of the drive were encrypted by TrueCrypt, which authorities said "renders the material extremely difficult to access." Detective Superintendent Caroline Goode stated the hard drive contained around 60 gigabytes of data, "of which only 20 have been accessed to date." She further stated the process to decode the material was complex and "so far only 75 documents have been reconstructed since the property was initially received." Guardian contributor Naomi Colvin concluded the statements were misleading, stating that it was possible Goode was not even referring
