About the PH!SH framework
PH!SH is an open classification of phishing: how the attack works, what it pretends to be, and what it asks for. It comes out of the phishing that employees at Hoxhunt customers report: real emails that passed the email gateways and landed in inboxes. Every entry describes a pattern that recurs there.
Why phishing needs its own framework
MITRE ATT&CK® maps the whole intrusion lifecycle, and it compresses delivery into a small number of techniques. That’s the right level of detail for endpoint and network defense, but too coarse for the part of the attack a person actually sees.
ATT&CK does not describe the lure. PH!SH fills that gap and links back to ATT&CK, so an incident classified here still fits your existing reporting.
PH!SH does not classify the attacker’s objective. ATT&CK already names that layer, so the tactic columns on the ATT&CK view belong to ATT&CK rather than to PH!SH.
The three layers
How entries are numbered
Techniques use TE, themes TH, and calls to action CTA, each followed by a four-digit number. Sub-entries add a dotted suffix, so TE0005.3 is the PDF-file variant of malicious attachments.
IDs are stable. An ID keeps its meaning in every later release and is never reused for a different concept, so a report tagged today still reads correctly tomorrow.
Relationship to other frameworks
Each entry lists the ATT&CK techniques it relates to. A mapping points at related work rather than claiming the two entries mean the same thing. A PH!SH entry is often more specific, and it may touch several ATT&CK techniques and vice versa.
The ATT&CK view exports a Navigator layer, which you can open in ATT&CK Navigator next to your own layers.
