A new Android banking Trojan has been found out in numerous destructive strategies all over the world. Dubbed ‘Nexus’ by Cleafy security researchers, the instrument is promoted as element of a Malware-as-a-Provider (MaaS) membership and offers attributes to conduct account takeover (ATO) attacks.
“In January 2023, a new Android banking Trojan appeared on a number of hacking discussion boards less than the identify of Nexus,” wrote the corporation in an advisory released on Tuesday. “However, [we] traced the to start with Nexus bacterial infections way in advance of the public announcement in June 2022.”
Analysing Nexus samples last yr, Cleafy found code similarities concerning the malware and SOVA, an Android banking trojan uncovered in mid-2021. At the time, the crew thought Nexus to be an up to date edition of SOVA.
“Despite the new MaaS system launched underneath the title Nexus, the authors may perhaps have reused some sections of SOVA internals to publish new options (and rewrite some of the current kinds),” explained Cleafy.
“Recently, the SOVA creator, who operates beneath the alias ‘sovenok,’ started sharing some insights on Nexus and its relationship with SOVA, calling out an affiliate who previously rented SOVA for stealing the overall source code of the task.”
Pertaining to capabilities facilitating ATO functions, Nexus delivers overlay assaults and keylogging things to do intended to steal victims’ credentials. It can also steal SMS messages (to obtain two-aspect authentication codes) and details from cryptocurrency wallets.

“Nexus is also geared up with a mechanism for autonomous updating,” Cleafy wrote. “A dedicated function asynchronously checks towards its C2 server for updates when the malware is operating.”
The malware also includes a module able of encryption, perhaps ransomware.
“This module would seem to be below progress thanks to the presence of debugging strings and the absence of usage references,” the corporation clarified.
Far more normally, Cleafy explained that the absence of a virtual network computing (VNC) module (that would permit for distant accessibility) at the moment boundaries the action range and abilities of Nexus.
“However, in accordance to the an infection level retrieved from multiple C2 panels, Nexus is a real threat that is capable of infecting hundreds of gadgets all over the environment,” the security staff warned. “Because of that, we can not exclude that it will be ready to take the stage in the upcoming number of months.”
