Complex malware known as Regin is the suspected technology behind sophisticated cyberattacks conducted by U.S. and British intelligence agencies on the European Union and a Belgian telecommunications company, according to security industry sources and technical analysis conducted by The Intercept.
Regin was found on infected internal computer systems and email servers at Belgacom, a partly state-owned Belgian phone and internet provider, following reports last year that the company was targeted in a top-secret surveillance operation carried out by British spy agency Government Communications Headquarters, industry sources told The Intercept.
The malware, which steals data from infected systems and disguises itself as legitimate Microsoft software, has also been identified on the same European Union computer systems that were targeted for surveillance by the National Security Agency.
The hacking operations against Belgacom and the European Union were first revealed last year through documents leaked by NSA whistleblower Edward Snowden. The specific malware used in the attacks has never been disclosed, however.
The Regin malware, whose existence was first reported by the security firm Symantec on Sunday, is among the most sophisticated ever discovered by researchers. Symantec compared Regin to Stuxnet, a state-sponsored malware program developed by the U.S. and Israel to sabotage computers at an Iranian nuclear facility. Sources familiar with internal investigations at Belgacom and the European Union have confirmed to The Intercept that the Regin malware was found on their systems after they were compromised, linking the spy tool to the secret GCHQ and NSA operations.
Ronald Prins, a security expert whose company Fox IT was hired to remove the malware from Belgacom’s networks, told The Intercept that it was “the most sophisticated malware” he had ever studied.
“Having analyzed this malware and looked at the [previously published] Snowden documents,” Prins said, “I’m convinced Regin is used by British and American intelligence services.”
A spokesman for Belgacom declined to comment specifically about the Regin revelations, but said that the company had shared “every element about the attack” with a federal prosecutor in Belgium who is conducting a criminal investigation into the intrusion. “It’s impossible for us to comment on this,” said Jan Margot, a spokesman for Belgacom. “It’s always been clear to us the malware was highly sophisticated, but ever since the clean-up this whole story belongs to the past for us.”
In a hacking mission codenamed Operation Socialist, GCHQ gained access to Belgacom’s internal systems in 2010 by targeting engineers at the company. The agency secretly installed so-called malware “implants” on the employees’ computers by sending their internet connection to a fake LinkedIn page. The malicious LinkedIn page launched a malware attack, infecting the employees’ computers and giving the spies total control of their systems, allowing GCHQ to get deep inside Belgacom’s networks to steal data.
The implants allowed GCHQ to conduct surveillance of internal Belgacom company communications and gave British spies the ability to gather data from the company’s network and customers, which include the European Commission, the European Parliament, and the European Council. The software implants used in this case were part of the suite of malware now known as Regin.
One of the keys to Regin is its stealth: To avoid detection and frustrate analysis, malware used in such operations frequently adhere to a modular design. This involves the deployment of the malware in stages, making it more difficult to analyze and mitigating certain risks of being caught.
Based on an analysis of the malware samples, Regin appears to have been developed over the course of more than a decade; The Intercept has identified traces of its components dating back as far as 2003. Regin was mentioned at a recent Hack.lu conference in Luxembourg, and Symantec’s report on Sunday said the firm had identified Regin on infected systems operated by private companies, government entities, and research institutes in countries such as Russia, Saudi Arabia, Mexico, Ireland, Belgium, and Iran.
The use of hacking techniques and malware in state-sponsored espionage has been publicly documented over the last few years: China has been linked to extensive cyber espionage, and recently the Russian government was also alleged to have been behind a cyber attack on the White House. Regin further demonstrates that Western intelligence agencies are also involved in covert cyberespionage.
GCHQ declined to comment for this story. The agency issued its standard response to inquiries, saying that “it is longstanding policy that we do not comment on intelligence matters” and “all of GCHQ’s work is carried out in accordance with a strict legal and policy framework, which ensures that our activities are authorised, necessary and proportionate.”
The NSA said in a statement, “We are not going to comment on The Intercept’s speculation.”
The Intercept has obtained samples of the malware from sources in the security community and is making it available for public download in an effort to encourage further research and analysis. What follows is a brief technical analysis of Regin conducted by The Intercept’s computer security staff. Regin is an extremely complex, multi-faceted piece of work and this is by no means a definitive analysis.
In the coming weeks, The Intercept will publish more details about Regin and the infiltration of Belgacom as part of an investigation in partnership with Belgian and Dutch newspapers De Standaard and NRC Handelsblad.
