Patent attributes
The disclosed techniques provide systems and methods for detecting coordinated attacks on social networking databases containing personal end-user data. More specifically, various advanced persistent threat (APT) detection procedures are described that explore the commonality between specific targets of various private data accesses. In one embodiment, a threat detection tool is configured to process various private data accesses initiated by a source user account in order to identify associated query structures. The tool then applies one or more filters to the private data accesses to identify a subset of the private data accesses that have query structures indicating specific targets and processes these specific targets to determine if an access pattern exists. The access pattern can indicate, for example, a measure of commonality among two or more of the specific targets. If an access pattern exists, the threat detection tool can trigger an alarm.
