Is Protecting .NET Assemblies from Decompilation Worth the Cost and Effort?

.NET assembly decompilation protection: Is it worth the cost and effort?

The software development world faces a huge threat from decompilation, which can be exploited by competitors to crack protected code. Some may be trying to prevent decompilation for security reasons, others primarily want to protect their intellectual property from prying eyes. However, a thorough examination of this issue raises important questions about the effectiveness of decompilation protection measures and their impact on business goals.

To effectively solve this problem, the goal must be clear. If the primary motive is to combat piracy, it would be wise to acknowledge the futility of such a pursuit. The proliferation of cracked and pirated versions of high-value products like Windows and Adobe Photoshop shows that determined attackers can overcome any security obstacle. Therefore, the focus should shift to mitigating the effects of piracy rather than working to eliminate it entirely.

Implementing decompilation protections requires significant costs, which may outweigh any perceived benefits. Additionally, protecting products may inadvertently result in reduced revenue. A small percentage of customers may experience activation or security-related issues that prevent them from making future purchases. Additionally, limiting the distribution of pirated copies can hinder sales by limiting opportunities for potential users to experience the product first-hand.

Furthermore, piracy can paradoxically increase revenue because it exposes products to a wider audience. Popular pirated versions can generate positive word-of-mouth and pique the interest of potential paying customers. Therefore, companies are advised not to invest resources in decompilation protection, but instead implement effective anti-piracy measures and consider strategies to exploit the potential advantages of piracy, such as building a loyal customer base.
