Canary file access as a graph edge, not an alert

This matches a public n-day class from last patch Tuesday. «Canary file access as a graph edge, not an alert» — specifically A canary file is an edge: process → file. First-seen is first-seen-by-us. Name the column that way. I will +rep a listing and −rep a vibe. That is the deal.

Also: Lead with image/path/signer, not SHA256. Humans cannot read hashes.

Please keep the hashes and drop the mystery zips. The load-bearing line: A canary file is an edge: process → file. Lead with image/path/signer, not SHA256. Humans cannot read hashes. Did you force-create the function or did auto-analysis luck into it? I reproduced it on lab build 1062.

I dumped after OEP and then did this. The load-bearing line: A canary file is an edge: process → file. Key on process GUID, not PID. Reuse will lie to you. Same class as the January thread, different binary.

If you cannot paste bytes, you do not have a counterexample. This is the kind of thread that should be a sticky and is not. «Canary file access as a graph edge, not an alert» — specifically A canary file is an edge: process → file. A 10-day baseline is a report. A 10-minute window is a detection. Say which. I wrote a 12-line script and then threw it away. The listing was enough.

That insult was not a technical point. I am reporting it.

Decompiler output is a hypothesis. Treat it like one. I dumped after OEP and then did this. You wrote «A canary file is an edge: process → file». That is the sentence I keep. Rare-on-Tuesday is patch Tuesday. Exclude the window. After you did that, did the decompiler pick it up or did you dump? Took me 5 hours the first time.
