physically available to someone he/she does not trust, by booting the encrypted operating system with TrueCrypt's Rescue Disk instead of booting it directly from the hard disk. With the rescue disk, the user can restore TrueCrypt's MBR to the hard disk. Trusted Platform Module The FAQ section of the TrueCrypt website states that the Trusted Platform Module (TPM) cannot be relied upon for security, because if the attacker has physical or administrative access to the computer and you use it afterwards, the computer could have been modified by the attacker e.g. a malicious component—such as a hardware keystroke logger—could have been used to capture the password or other sensitive information. Since the TPM does not prevent an attacker from maliciously modifying the computer, TrueCrypt will not support the TPM. Security audits In 2013 a graduate student at Concordia University published a detailed online report, in which he states that he has confirmed the integrity of the distributed Windows binaries of version 7.1a. A crowdfunding campaign attempting to conduct an independent security audit of TrueCrypt was successfully funded in October 2013. A non-profit organization called the Open Crypto Audit Project (OCAP) was formed, calling itself "a community-driven global initiative which grew out of the first comprehensive public audit and cryptanalysis of the widely used encryption software TrueCrypt". The organization established contact with TrueCrypt developers, who welcomed the audit. Phase I of the audit was successfully completed on 14 April 2014, finding "no evidence of backdoors or malicious code". Matthew D. Green, one of the auditors, added "I think it's good that we didn't find anything super critical." One day after TrueCrypt's end of life announcement, OCAP confirmed that the audit would continue as planned, with Phase II expected to begin in June 2014 and wrap up by the end of September. The Phase II audit was delayed, but was completed 2 April 2015 by NCC Cryptography Services. This audit "found no evidence of deliberate backdoors, or any severe design flaws that will make the software insecure in most instances." The French National Agency for the Security of Information Systems (ANSSI) stated that while TrueCrypt 6.0 and 7.1a have previously attained ANSSI certification, migration to an alternate certified product is recommended as a precautionary measure.
