ATstake, Inc. was a computer security professional services company in Cambridge, Massachusetts, United States. It was founded in 1999 by Battery Ventures (Tom Crotty, Sunil Dhaliwal, and Scott Tobin) and Ted Julian. Its initial core team of technologists included Dan Geer (Chief Technical Officer) and the east coast security team from Cambridge Technology Partners (including Dave Goldsmith). History In January 2000, @stake acquired L0pht Heavy Industries (who were known for their many hacker employees), bringing on Mudge as its Vice President of Research and Development. Its domain name was atstake.com. In July 2000, @stake acquired Cerberus Information Security Limited of London, England, from David and Mark Litchfield and Robert Stein-Rostaing, to be their launchpad into Europe, the Middle East and Africa. @stake was subsequently acquired by Symantec in 2004. In addition to Dan Geer and Mudge, @stake employed many famous security experts including Dildog, Window Snyder, Dave Aitel, Katie Moussouris, David Litchfield, Mark Kriegsman, Mike Schiffman, Chris Wysopal, Alex Stamos, Cris Thomas, and Joe Grand. In September 2000, an @stake recruiter contacted Mark Abene to recruit him for a security consultant position. The recruiter was apparently unaware of his past felony conviction since @stake had a policy of not hiring convicted hackers. Mark was informed by a company representative that @stake could not hire him, saying: "We ran a background check." This caused some debate regarding the role of convicted hackers working in the security business. @stake was primarily a consulting company, but also offered information security training through the @stake academy, and created a number of software security tools: LC 3, LC 4 and LC 5 were versions of a password auditing and recovery tool also known as L0phtCrack WebProxy was a security testing tool for Web applications SmartRisk Analyzer was an application security analysis tool The @stake Sleuth Kit (TASK) was an open source digital forensics tool (now called The Sleuth Kit). Symantec later stopped selling LC5 to new customers citing US Government export regulations, and discontinued support in December 2006. In January 2009, L0phtCrack was acquired by the original authors from Symantec; L0phtCrack 6 was announced at the SOURCE Boston Conference on March 11, 2009. The technology underlying SmartRisk Analyzer was extended, and eventually brought to market by the Symantec spinoff Veracode. Symantec announced its acquisition of @stake on September 16, 2004, and completed the transaction on October 9, 2004. Several members of @Stake left to form
