Nested virt, enough CPU, no random steal. It worked. It also failed until I pinned the vCPU count.

If rr is flaky, your VM is flaky. Fix the VM.

I still keep a paper notebook for this kind of note. On «rr in a VM — the settings that did not lie»: Nested virt, enough CPU, no random steal. FakeNet that can reach the internet is not a simulator. I still have the snapshot named tool-265-pre.

Do not call people skids because they use Ghidra. Did this on ARM64 last week — same shape, different pain. You wrote «Nested virt, enough CPU, no random steal». That is the sentence I keep. Do not detonate in Docker. Shared kernel. VMs for samples, containers for tools. Same class as the March thread, different binary.

I want the listing, not the decompiler story. «rr in a VM — the settings that did not lie» — specifically Nested virt, enough CPU, no random steal. Transfer samples as a hashed read-only ISO. Not drag-drop. I will +rep a listing and −rep a vibe. That is the deal.

You are describing a live target. Stop. Patched class only. Agreed on the class, not on the tool. You wrote «Nested virt, enough CPU, no random steal». That is the sentence I keep. Name snapshots date plus hash plus pre/post. 'snapshot 12' loses a week. Did page heap see it, or only the sanitizer? I still have the snapshot named tool-265-pre.

Quietly the best note on this board this month. The load-bearing line: Nested virt, enough CPU, no random steal. FakeNet that can reach the internet is not a simulator. Pinned a comment at 0x140004750 in the listing.

Take the telegram pitch to the bin. Market listing or nothing. I disagree with the tone, not the bytes. On «rr in a VM — the settings that did not lie»: Nested virt, enough CPU, no random steal. Tools snapshot in 8 minutes or you will not restore it. I still have the snapshot named tool-265-pre.

Please keep the hashes and drop the mystery zips. On «rr in a VM — the settings that did not lie»: Nested virt, enough CPU, no random steal. Tools snapshot in 8 minutes or you will not restore it. Same class as the June thread, different binary.

Quote the bytes or sit down. Please keep the hashes and drop the mystery zips. «rr in a VM — the settings that did not lie» — specifically Nested virt, enough CPU, no random steal. Clipboard off on the detonation VM. I pasted a token once. Version in my shot: current lab snapshot, not last year's blog.

Good. Dated shot, version in the post. You wrote «Nested virt, enough CPU, no random steal». That is the sentence I keep. Do not detonate in Docker. Shared kernel. VMs for samples, containers for tools. After you did that, did the decompiler pick it up or did you dump? Version in my shot: current lab snapshot, not last year's blog.

You are treating a checksum as a signature again. Did this on ARM64 last week — same shape, different pain. You wrote «Nested virt, enough CPU, no random steal». That is the sentence I keep.

This is the kind of thread that should be a sticky and is not. On «rr in a VM — the settings that did not lie»: Nested virt, enough CPU, no random steal. PE-sieve is a lead. It is not a verdict. My note id for this: 109-10.

You skipped isolation and then asked why the box is dirty. That is on you. I reproduced it twice before I believed you. «rr in a VM — the settings that did not lie» — specifically Nested virt, enough CPU, no random steal. Profile YARA. One looping regex will eat a core. I wrote a 12-line script and then threw it away. The listing was enough.

This is the writeup I wanted when I was stuck. You wrote «Nested virt, enough CPU, no random steal». That is the sentence I keep. FakeNet that can reach the internet is not a simulator. I still have the snapshot named tool-265-pre.

I am not moving this to DMs so you can yell. Stay on the class. Quietly the best note on this board this month. «rr in a VM — the settings that did not lie» — specifically Nested virt, enough CPU, no random steal. FakeNet that can reach the internet is not a simulator. Which build of the tool? I got burned mixing notes across versions. Pinned a comment at 0x1400007ad in the listing.

Bookmarking this for the lab wiki. You wrote «Nested virt, enough CPU, no random steal». That is the sentence I keep. Do not detonate in Docker. Shared kernel. VMs for samples, containers for tools. Took me 8 hours the first time.
