Hex-Rays just dropped a brand-new Python API that makes IDA scripting cleaner, shorter, and way more Pythonic.

See the difference in 5 seconds

OLD (IDAPython SDK):
ea = here()
func = get_func(ea)
name = get_func_name(func.start_ea)

NEW (IDA Domain API):
from ida_domain import Database
with Database() as db:
    print(db.functions.get_name(func))

Key points
• No more verbose IDAPython boilerplate
• Runs inside IDA or headless (batch automation)


Install:

 pip install ida-domain
 

Docs & examples: https://hex-rays.com/blog/introducing-the-ida-domain-api

SurfaceBlobKit — a dynamic loader for Android native-surface (.so) directly from memory.
• Loads API-specific blobs (Android 9–13)
• Resolves functions such as createNativeWindow
• Exposes a safe and unified API

multi-platform testing, integration in custom builds (e.g., kernel modules, device-specific surface handling).
