 The CRIME exploit was hypothesized by Adam Langley, and first demonstrated by the security researchers Juliano Rizzo and Thai Duong, who also created the BEAST exploit.The exploit was due to be revealed in full at the 2012 ekoparty security conference.Rizzo and Duong presented CRIME as a general attack that works effectively against a large number of protocols, including but not limited to SPDY (which always compresses request headers), TLS (which may compress records) and HTTP (which may compress responses).
