It began as a mini- game inside the [Nov 15] game “ 2”, but was such a big hit that it was released standalone through the Xbox Live Marketplace. Despite never being a boxed game sold on store shelves, it proved to be extremely popular, and demonstrated the viability of moving away from physical game discs towards downloads.

CrackStation Nov. 17-18, 2007 Security consultant Nick Breese described his “CrackStation” project at the Kiwicon hacker conference in New Zealand. The CrackStation's password cracking software employed six of the PlayStation 3’s [Nov 11] processors (out of 8) to perform 1.4 billion calculations per second to generate MD5 cryptographic hash functions [May 6]. This was a dramatic increase in speed over similar software running on Intel architectures, which could only manage a meager 10 - 15 million calculations per second. His announcement raised serious concerns over the safety of MD5 for encryption. In 2010, the CMU Software Engineering Institute stated that MD5 was “cryptographically broken and unsuitable for further use”. Most US government applications now require the SHA-2 family of hash functions.
