Methods, systems, and techniques for facilitating identification of electronic data exfiltration. A message transmission log and screenshot metadata are obtained. A screenshot corresponding to the screenshot metadata is matched to a sent electronic message, such as an email, having a file attachment represented in the message transmission log to generate an event. The screenshot metadata indicates that the screenshot was captured prior to when the message transmission log indicates the electronic message was sent. An anomaly score is determined for the sent electronic message is determined by applying unsupervised machine learning, such as by applying an isolation forest, to score the sent electronic message relative to a baseline. The anomaly score meeting or exceeding an anomaly threshold is treated as potentially being indicative of electronic data exfiltration.
