ESET researchers have identified an active campaign targeting Android users, conducted by the Bahamut APT group. This campaign has been active since January 2022 and malicious apps are distributed through a fake SecureVPN website that provides only Android apps to download.
Note that although the malware employed throughout this campaign uses the name SecureVPN, it has no association whatsoever with the legitimate, multiplatform SecureVPN software and service.
ESET researchers discovered at least eight versions of the Bahamut spyware. The malware is distributed through a fake SecureVPN website as trojanized versions of two legitimate apps – SoftVPN and OpenVPN. These malicious apps were never available for download from Google Play.
The malware is able to exfiltrate sensitive data such as contacts, SMS messages, call logs, device location, and recorded phone calls. It can also actively spy on chat messages exchanged through very popular messaging apps including Signal, Viber, WhatsApp, Telegram, and Facebook Messenger; the data exfiltration is done via the keylogging functionality of the malware, which misuses accessibility services.
The campaign appears to be highly targeted, as we see no instances in our telemetry data.
