Description

'Identifies email attacks detected by Abnormal Security whose attack type maps to a high-risk category (credential phishing, Business Email Compromise, invoice/payment fraud, malware, extortion, sensitive-data phishing, internal account-takeover attacks, or scams). Lower-risk categories such as Spam, Graymail, and Reconnaissance are intentionally excluded. Use this to triage targeted email threats that reached a mailbox.'
