A malicious app disguised as the official account management portal for French telecom giant Orange S.A. is targeting customers of Chase, Wells Fargo, Bank of America, and Capital One, as well as almost 400 other financial institutions.
According to researchers, this is only the beginning.
Researchers at Lookout cautioned in a recent report that once downloaded, the malware - a version of banking trojan Anubis – collects the user's personal data and uses it to mislead them. And it's not just huge bank customers that are at risk, according to the researchers: Crypto wallets and virtual payment networks are also being targeted.
The Lookout report stated, “As a banking trojan malware, Anubis’ goal is to collect significant data about the victim from their mobile device for financial gain.”
“This is done by intercepting SMSs, keylogging, file exfiltration, screen monitoring, GPS data collection, and abuse of the device’s accessibility services.”
The malicious version of the Orange Telecom account management software was uploaded to the Google Play store in July 2021 and then removed, but analysts believe this was only a test of Google's antivirus defences and that it could reappear shortly.
The report added, “We found that obfuscation efforts were only partially implemented within the app and that there were additional developments still occurring with its command-and-control (C2) server. We expect more heavily obfuscated distributions will be submitted in the future.”
New Anubis Tricks
The malicious version of the Orange Telecom account management software was uploaded to the Google Play store in July 2021 and then removed, but analysts believe this was only a test of Google's antivirus defences and that it could reappear shortly.
The banking trojan connects to the command-and-control (C2) server after being downloaded on the device and downloads another application to start the SOCKS5 proxy.
“This proxy allows the attacker to enforce authentication for clients communicating with their server and mask communications between the client and C2. Once retrieved and decrypted, the APK is saved as ‘FR.apk’ in ‘/data/data/fr.orange.serviceapp/app_apk,'” the researchers stated.
The user is then prompted to disable Google Play Protect, giving the attacker complete control, according to the research.
Banks, reloadable card businesses, and cryptocurrency wallets are among the 394 apps targeted by fr.orange.serviceapp, according to the researchers.
The Anubis client was linked back to a half-completed crypto trading platform, according to the Lookout team.
Anubis, which was first discovered in 2016, is freely available as open-source code on underground forums, along with instructions for budding banking trojan criminals, according to the research.
According to Lookout, the basic banking trojan has added a credential stealer to the mix in this current edition of Anubis code, putting logins for cloud-based platforms like Microsoft 365 in danger.
As per Kristina Balaam, a security researcher with Lookout, the Lookout team was unable to discover any successful attacks linked to the Orange S.A. campaign.
“While we can’t be certain whether the app has been used in a successful attack, we do know they are targeting U.S. banks including Bank of America, U.S. Bank, Capital One, Chase, SunTrust and Wells Fargo,” Balaam stated.
