MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is detected as a dropper by ClamAV and exhibits characteristics of a phishing lure, including an image-only presentation with an embedded action trigger. The heuristic 'PDF_IMAGE_LURE' indicates that the document likely contains a screenshot designed to hide a clickable button. This button, when clicked, directs the user to the external URL https://stratawellbeing.co.uk/folder/document/DOCsignsecured/DOCsignsecured/dsign/, suggesting a phishing or malware distribution attempt.
