Ida Pro 7.5
Why would you leave IDA Pro 7.5?
But many reverse engineers keep IDA 7.5 as a secondary install because:
A patching plugin that lets you modify assembly directly within IDA. Perfect for binary patching exploits or removing anti-debug checks.
Hex-Rays sells subscriptions. As of 2024, IDA Pro 7.5 is considered "legacy." You can purchase a license for 7.5, but most new sales include a maintenance contract allowing upgrade to 8.x.
Important: Pirated copies of IDA Pro 7.5 exist on torrent sites. Running them is extremely dangerous — threat actors embed backdoors in cracked RE tools. If you are analyzing malware, a cracked IDA is itself malware. Always obtain from hex-rays.com.
No report is honest without criticism. IDA Pro 7.5 was also infamous for what it lacked:
| Issue | Impact | |-------|--------| | No native Apple Silicon support | RE on M1 Macs required Rosetta 2, causing slowdowns. | | Python 3 transition pains | IDA 7.5 supported Python 3, but many legacy scripts broke. The plugin ecosystem was chaotic for months. | | Ghidra’s collaboration features | Ghidra offered real-time co-reversing (like Google Docs). IDA 7.5 remained single-user. | | Price still high | Despite bundling the decompiler, a single license was ~$3,000+. Ghidra remained free. |
A must-have for decompiler users. It helps reconstruct virtual tables, identify function argument types, and rename structures efficiently.
IDA Pro 7.5 is not a revolutionary leap, but it solidifies Hex‑Rays’ position as the industry standard for interactive reverse engineering. The ARM64 decompiler and microcode API are standout features. For teams already on 7.x, the upgrade is worthwhile for Apple Silicon and improved performance. For open‑source alternatives, Ghidra 9.2+ now matches about 80% of IDA’s capability, except for the polished decompiler and debugger integration.
Final score: 8.5 / 10

IDA Pro 7.5, released in May 2020, introduced several transformative features that significantly streamlined the reverse engineering workflow, most notably the transition to hierarchical file organization and the expansion of its decompilation suite. Key Features and Breakthroughs
Tree-Like Folder Structure: For the first time, users could organize functions, names, imports, structures, and enums into a hierarchical folder system. This replaced flat lists and made navigating large, complex binaries substantially more efficient.
MIPS Decompiler: A dedicated decompiler for 32-bit MIPS was added, supporting all standard MIPS binaries, including compact encodings and transparently handling complex delay slots.
Lumina Expansion: The Lumina server, which stores function signatures to help identify known code, was expanded to include support for MIPS and PowerPC (PPC) architectures.
Python 3 Integration: This version solidified the shift toward Python 3 as the default scripting environment, though it caused compatibility issues for older Python 2 scripts like idb2pat.py. Major Platform Support and Service Packs
The release cycle for 7.5 was heavily influenced by major updates to Apple's ecosystem:
iOS 14 & macOS 11 (Big Sur): Service Packs (SP2 and SP3) were specifically released to support Apple Silicon and the new MH_FILESET kernelcache format. Debugger Enhancements : Added debugging support for the
processor and Bochs 2.6.10, along with improved multi-threaded program debugging in GDB.
C++ Support: Added support for C++20 operators, such as "spaceship" (<=>) and co_await, for both VC++ and GCC compilers. Security Warning ida pro 7.5
It is important to note that researchers have identified trojanized installers of IDA Pro 7.5 distributed by threat groups like Lazarus. These malicious versions contain DLLs (such as idahelp.dll) designed to deliver RATs (Remote Access Trojans) to the researcher's machine.

IDA Pro 7.5 remains a landmark release for reverse engineers, introducing several features that fundamentally changed the workflow for analyzing modern software. The Big Shift: Native Support and Speed
The headline of version 7.5 was undoubtedly the transition to native support for Apple Silicon (M1/M2 chips). This allowed macOS users to run IDA without the overhead of Rosetta 2, providing a massive boost in processing speed for large binaries. 🚀 Key Features in IDA Pro 7.5
Internal Decompiler Enhancements: Significant improvements to the MIPS and PPC decompilers, making the generated C-code much more readable.
Tree View in Structures: A new hierarchical view for structures and enums made navigating complex data types significantly easier.
Folder View: Users could finally organize functions and names into folders, a huge win for managing massive projects with thousands of subroutines.
Libcurl Integration: IDA started using libcurl for network operations, improving how it handles symbol server downloads.
Lumina Improvements: Enhanced the Lumina server functionality, allowing for better identification of well-known functions across different binaries. Why It Still Matters Today
While IDA has moved on to versions 8.x and beyond, 7.5 is often cited as one of the most stable "classic" versions. It solidified the Python 3 transition that began in 7.4, ensuring that scripts written today still have a high degree of compatibility with this specific release.
💡 Pro Tip: If you are working on modern macOS malware or iOS apps, the native ARM support introduced in this version is the bare minimum you need for a smooth experience.

The story of IDA Pro 7.5 is a major cautionary tale in the cybersecurity world, marked by a sophisticated attack where the "hunters became the hunted." While IDA Pro 7.5 (released by
) was a standard update for the industry-leading disassembler, it became infamous in late 2021 when the Lazarus Group
, a North Korea-linked APT (Advanced Persistent Threat), used it as bait to compromise cybersecurity researchers. The Lazarus Trojan Campaign In November 2021, ESET researchers discovered that hackers were distributing a trojanized, pirated version
of IDA Pro 7.5 online. The attack targeted security professionals who might attempt to use "cracked" software to avoid the high licensing costs of the tool. : A seemingly functional installer for IDA Pro 7.5. The Payload : The installer was bundled with two malicious DLLs: win_fw.dll idahelp.dll The Execution : During installation, win_fw.dll would run and set up a scheduled task to load idahelp.dll . This second component would then download the NukeSpeed RAT (Remote Access Trojan) from a remote server. The Result
: Once infected, the attackers could steal sensitive data, log keystrokes, take screenshots, and execute remote commands on the researcher's machine. Technical Context of Version 7.5
