In our firmware extraction suite, we started searching patterns with Yara, but it was so slow we switched to Hyperscan: https://github.com/onekey-sec/unblob/blob/main/unblob/finder...

We are quite happy with the huge performance boost, never looking back :) Yara was even segfaulted when we tried to extract an Ubuntu ISO image with it, never had problems like that with Hyperscan.

The only problem with Hyperscan is that it only supports Intel CPUs (it has some hand-crafted assembly), so it doesn't work on Apple M1 Macs, but there is a fork called VectorScan, which is working on ARM: https://github.com/VectorCamp/vectorscan

We implemented a couple of small DSL classes in Python to be able to define YARA-like rules, it might be useful for you too, check it out here: https://github.com/onekey-sec/unblob/blob/cdd7a46667ffdfdfae...

There's also Vectorscan[1], which is a fork of Hyperscan that runs on more platforms.
