'RedAlpha': This Chinese Cyberspy Group is Targeting Governments & Humanitarian Entities

 

RedAlpha, a Chinese state-sponsored cyberespionage group, has been observed targeting numerous government organisations, humanitarian organisations, and think tanks over the last three years. 

The advanced persistent threat (APT) actor, also known as Deepcliff and Red Dev 3, has been active since at least 2015, focusing on intelligence collection and surveillance of ethnic and religious minorities such as the Tibetan and Uyghur communities. 

According to cybersecurity firm Recorded Future, RedAlpha has registered hundreds of domains impersonating global government, think tank, and humanitarian organisations such as Amnesty International, the American Institute in Taiwan (AIT), the International Federation for Human Rights (FIDH), the Mercator Institute for China Studies (MERICS), and Radio Free Asia (RFA).

According to Recorded Future, the attacks are consistent with previous RedAlpha targeting of entities of interest to the Chinese Communist Party (CCP). Taiwanese organisations were also targeted, most likely for intelligence gathering. The campaign's goal has been to collect credentials from targeted individuals and organisations in order to gain access to their email and other communication accounts.

“RedAlpha’s humanitarian and human rights-linked targeting and spoofing of organizations such as Amnesty International and FIDH is particularly concerning given the CCP’s reported human rights abuses in relation to Uyghurs, Tibetans, and other ethnic and religious minority groups in China,” Recorded Future notes.

The cyberespionage group is known for using weaponized websites - which mimics well-known email service providers or specific organisations - as part of its credential-theft campaigns, but the APT registered more than 350 domains last year.

This activity was distinguished by the use of resellerclub[.]com nameservers, as well as the use of virtual private server (VPS) hosting provider Virtual Machine Solutions LLC (VirMach), overlapping WHOIS registrant information (including names, email addresses, and phone numbers), consistent domain naming conventions, and the use of specific server-side components.

About RedAlpha:

The group has recorded hundreds of domains typosquatting major email and storage service providers, including Yahoo (135 domains), Google (91 domains), and Microsoft (70), as well as domains typosquatting multiple countries' ministries of foreign affairs (MOFAs), Purdue University, Taiwan's Democratic Progressive Party, and the aforementioned and other global government, think tank, and humanitarian organisations.

The cyberespionage group registered at least 16 domains impersonating the Berlin-based non-profit organisation MERICS during the first half of 2021, which coincided with the Chinese MOFA sanctioning the think tank.

“In many cases, observed phishing pages mirrored legitimate email login portals for the specific organizations named above. We suspect that this means they were intended to target individuals directly affiliated with these organizations rather than simply imitating these organizations to target other third parties,” Recorded Future says.

RedAlpha has also shown a consistent focus on targeting Taiwanese entities over the last three years, including through multiple domains mimicking the American Institute in Taiwan (AIT), the de facto embassy of the United States of America. The hacking group was also noticed spreading its campaigns to target Brazilian, Portuguese, Taiwanese, and Vietnamese ministries of foreign affairs, as well as India's National Informatics Centre (NIC).

“We identified multiple overlaps with previous publicly reported RedAlpha campaigns that allowed us to assess this is very likely a continuation of the group’s activity. Of note, in at least 5 instances the group appeared to re-register previously owned domains after expiry,” Recorded Future notes.

The cybersecurity firm has discovered a connection between RedAlpha and a Chinese information security firm - email addresses used to register spoofing domains appear in job listings and other web pages associated with the organisation - and believes the threat actor is based in China.

“The group’s targeting closely aligns with the strategic interests of the Chinese government, such as the observed emphasis on China-focused think tanks, civil society organizations, and Taiwanese government and political entities. This targeting, coupled with the identification of likely China-based operators, indicates a likely Chinese state-nexus to RedAlpha activity,” Recorded Future concludes.
