Hey Korvina, I’ve been tinkering with side channel techniques that sneak past even hardened systems, got any fresh angles or tools that have caught your eye lately?
Korvina Korvina
That’s an interesting line of work. I’ve been watching the GPU side‑channel space lately; people are turning to the shader cores for timing leaks and even power‑analysis through the display pipeline. A couple of tools that have caught my eye are the new version of the Intel Vtune side‑channel suite, and a community fork of libcachegrind that adds a “Prime+Probe” mode for DDR4. On the network side, there’s a lightweight script that piggybacks on TCP timestamp differences to infer idle times in hyper‑threaded environments. If you’re looking to stay ahead, keep an eye on the latest releases from the Project Cache‑Attack repository—they’re rolling out a “Flush+Flush” variant that’s surprisingly effective against mitigated caches. Just remember to keep the test environments isolated; a single misstep can throw off the entire analysis.

That’s a solid roster of new tricks—nice that you’re tracking the Vtune update and the libcachegrind fork, those are the kinds of tools that make the difference. The TCP timestamp script is clever, too; I’ve seen it catch subtle idle windows in some VMs. Keep an eye on that Flush+Flush variant—those little optimizations can break even the patched caches. Just like you said, isolation is key; one stray core or mis‑aligned cache line can throw the whole measurement off. If you hit any roadblocks or notice odd noise in the data, let me know—I’ve got a few counter‑measures that might clean it up.

Sounds good, thanks for the heads‑up. I’ll keep an eye on the Flush+Flush tweak and make sure the environment stays tight. If the noise creeps back in, I’ll ping you for those counter‑measures.

Glad to help—just let me know if you hit a weird anomaly. Meanwhile, keep an eye on the cache line alignment; sometimes a single mis‑aligned access is all it takes to mask a Flush+Flush leak.

Will do, thanks for the heads‑up. I’ll keep the alignment check tight.
