Industry observers say the unveiling of the Regin malware, which came after more than half a decade in the wild, highlights the need for better detection methods.
Symantec Inc.'s discovery of the Regin malware, part of a long-term nation-state-sponsored cyberespionage campaign, has already been compared to the likes of Stuxnet and Flame, two of the most sophisticated pieces of malware ever created. While the expertise needed to create Regin is unquestioned, security industry observers say Regin again proves that more organizations and vendors need to be focused on threat detection rather than prevention.
Symantec's technical analysis of Regin, released late last week, exposed a malware platform that is both powerful and highly customizable. The first version of Regin was used since at least 2008 until 2011, according to Symantec's analysis, while a second version was spotted in 2013.
As a modular malware platform, Regin contains a number of components that rely on each other to function. This design allows attackers to deploy a number of different payloads depending on specific targets and situations. Symantec said the multi-stage loading architecture, which is similar to that of Stuxnet and Duqu, made it difficult to analyze Regin as not all of the malware's components were available at the same time.
And unlike many other advanced persistent threats (APTs), which are typically focused on collecting valuable intellectual property, Symantec's paper indicates that Regin is unique because it is geared toward collecting a variety of nonspecific data and monitoring individuals or organizations for lengthy periods.

"Regin is a complex piece of malware whose structure displays a degree of technical competence rarely seen," wrote Symantec's security response team in a blog post. "It is likely that its development took months, if not years, to complete and its authors have gone to great lengths to cover its tracks."
