MSK Notice of Accellion Data Incident
Memorial Sloan Kettering Cancer Center (MSK) was recently notified by a third-party software vendor, Accellion, Inc., of a technical vulnerability in a document-sharing system used at MSK. MSK was one of many Accellion customers whose document-sharing systems were involved in this incident. After a full investigation, we discovered that an unauthorized party was able to access and copy a subset of electronic documents stored on the system.
