4 actors on record using it
Every mark is an actor ATT&CK records using this technique. Red ones also exploit a CVE in CISA KEV.
Open T0865 on attack.mitre.orgAdversaries may use a spearphishing attachment, a variant of spearphishing, as a form of a social engineering attack against specific targets. Spearphishing attachments are different from other forms of spearphishing in that they employ malware attached to an email. All forms of spearphishing are electronically delivered and target a specific individual, company, or industry. In this scenario, adversaries attach a file to the spearphishing email and usually rely upon User Execution to gain execution and access.
