![]() The project also wants a legal review of the software's license and the creation of a deterministic build process to ensure that pre-compiled TrueCrypt binaries have not been altered. Phase two will consist of a formal cryptanalysis of the program's cryptographic functions. Security Audit Systems provide penetration testing services using the latest real world attack techniques, giving our clients the most in-depth and accurate information to help mitigate potential threats to their online assets. The source code review is just the first phase of the professional audit envisioned by the Open Crypto Audit Project. Cyber Security Solutions Penetration Testing Experts. Both uncovered a number of security flaws, the most serious being the use of Windows programming interface to. TrueCrypt's developers have remained anonymous over the years for privacy reasons, and even though the program's source code has been publicly available for anyone to look at, questions have been raised about the integrity of the build process, as most people download and use pre-compiled binaries of TrueCrypt. The audit, which was contracted out by the Germany Federal Office for Security in Information Technology, largely mirrors the conclusions reached in April, where a separate group of auditors provided the same conclusions on TrueCrypt. The project chose to focus on TrueCrypt because, despite being popular and important for a lot of people, the application has never been thoroughly analyzed from a security perspective. The Open Crypto Audit Project that contracted iSEC to perform the professional code review was created in October by Matthew Green, a cryptographer and research professor at Johns Hopkins University in Baltimore and Kenneth White, a security research and development engineer at Social & Scientific Systems, a clinical research and health consultancy. "This includes issues such as lack of comments, use of insecure or deprecated functions, inconsistent variable types and so forth." From a quality perspective, the source code for both the TrueCrypt bootloader and Windows kernel driver failed to meet expected standards for secure code, the iSEC auditors said in the report. We need help making it better and more secure. There's also room for improvement beyond resolving the identified issues. The TrueCrypt Audit People, businesses, and governments all over the world use TrueCrypt to protect their privacy. The auditors recommended that TrueCrypt's developers should make the PBKDF2 iteration count configurable to keep pace with advances in CPU and GPU performance that improve the feasibility of brute-force attacks or, in the longer term, switch to a different key derivation function called Scrypt that uses larger amounts of memory and requires more expensive hardware to attack via brute-force techniques. In both cases, this iteration count is too small to prevent password guessing attacks for even moderately complex passwords." "The iteration count used by TrueCrypt is either 1000 or 2000, depending on the hash function and use case. "Developers are responsible for specifying an iteration count that influences the computational cost of deriving a key from a password," the iSEC auditors wrote in the full technical report.
