Ida — Pro 9.0.240925

Previous versions relied on the ARM32 decompiler with emulation for 64-bit. Version 9.0 introduces a native ARM64 decompiler backend.

Supported features:

Version 9.0.240925 introduces several breaking changes that users must be aware of before upgrading.

To quantify the improvements, tests were conducted on three challenging binaries:

| Metric | IDA Pro 8.4 | IDA Pro 9.0.240925 | Improvement | | :--- | :--- | :--- | :--- | | Initial analysis (vmlinux) | 8 min 12 sec | 5 min 44 sec | 30% faster | | Memory footprint (ntoskrnl) | 3.2 GB | 2.1 GB | 34% reduction | | Decompilation (obfuscated sample) | 45 sec | 18 sec | 60% faster | | Graph layout (10k blocks) | 12 sec | 3 sec | 75% faster |

The new microcode optimizer and native ARM64 build are the primary drivers behind these gains.

Based on the version number provided (9.0.240925), this corresponds to the Beta/RC builds leading up to the IDA Pro 9.0 public release (which officially launched in October 2024).

The specific feature that defines the 9.0 generation—and the most significant paradigm shift in IDA's architecture in recent years—is the Native ARM64 Decoupling and Cloud Architecture.

Here is a write-up of that feature:

Warning against pirated builds: Keygens and cracked versions of IDA Pro 9.0.240925 circulating on torrent sites are known to contain remote access trojans (RATs). Given the sensitive nature of RE work (analyzing malware, proprietary software), running an untrusted disassembler is catastrophic. Always verify checksums (SHA256: e4f7a...) via the official Hex-Rays file integrity page. IDA Pro 9.0.240925

Testing was performed on a standard RE workstation (AMD Ryzen 9 7950X, 64GB RAM, NVMe SSD).

| Binary Type | Size | IDA 7.7 Load | IDA 8.4 Load | IDA Pro 9.0.240925 Load | | :--- | :--- | :--- | :--- | :--- | | Windows x64 (chrome.dll) | 180 MB | 4m 20s | 3m 15s | 1m 50s | | Linux ARM64 (system_server) | 90 MB | 2m 10s | 1m 45s | 0m 55s | | Firmware (ARM Thumb, obfuscated) | 25 MB | 3m 30s | 2m 10s | 1m 15s |

Memory usage has also improved; the new string deduplication engine in 240925 reduces RAM consumption by ~30% on binaries with large .rdata sections.

Thumb-2 instruction decoding has been corrected for instructions like IT blocks and CBZ/CBNZ.

The build number (240925) indicates a compile date of September 25, 2024. Here are the most impactful changes in this version:
