There is a new malware looking for your information like tele conversation, chatting, called Regin. It is considered to be a mass surveillance and data collection tool. This tool target both companies and individuals. Experts believe that this program is the work of a nation-state.
This is an advanced spying tool, it displays a degree of technical competence rarely seen and has been used in spying operations against governments, infrastructure operators, businesses, researchers, and private individuals.
As outlined in a new technical whitepaper from Symantec, Backdoor.Regin is a multi-staged threat and each stage is hidden and encrypted, with the exception of the first stage. Executing the first stage starts a domino chain of decryption and loading of each subsequent stage for a total of five stages. Each individual stage provides little information on the complete package. Only by acquiring all five stages is it possible to analyze and understand the threat.
Regin infections have been observed in a variety of organizations between 2008 and 2011, after which it was abruptly withdrawn. A new version of the malware resurfaced from 2013 onwards. Targets include private companies, government entities and research institutes. Almost half of all infections targeted private individuals and small businesses. Attacks on telecoms companies appear to be designed to gain access to calls being routed through their infrastructure.
Regin’s developers put considerable effort into making it highly inconspicuous. Its low key nature means it can potentially be used in espionage campaigns lasting several years. Even when its presence is detected, it is very difficult to ascertain what it is doing. Symantec was only able to analyze the payloads after it decrypted sample files.
It has several “stealth” features. These include anti-forensics capabilities, a custom-built encrypted virtual file system (EVFS), and alternative encryption in the form of a variant of RC5, which isn’t commonly used. Regin uses multiple sophisticated means to covertly communicate with the attacker including via ICMP/ping, embedding commands in HTTP cookies, and custom TCP and UDP protocols.
Regin is a highly-complex threat which has been used in systematic data collection or intelligence gathering campaigns. The development and operation of this malware would have required a significant investment of time and resources, indicating that a nation state is responsible. Its design makes it highly suited for persistent, long term surveillance operations against targets.
The discovery of Regin highlights how significant investments continue to be made into the development of tools for use in intelligence gathering. Symantec believes that many components of Regin remain undiscovered and additional functionality and versions may exist. Additional analysis continues and Symantec will post any updates on future discoveries
