The Nexus Android banking trojan has been recently introduced as a malware-as-a-service (MaaS) on underground forums, with a pricing model of $3,000 per month for subscription. It is believed to have a connection to the Sova banking trojan and is primarily utilized for attacking banking and cryptocurrency accounts. Among its functionalities are SMS interception, data theft through credentials, and exploitation of Accessibility Services to extract sensitive data such as crypto-wallet information and Google Authenticator 2FA codes. The trojan is equipped with an automatic update mechanism and is potentially expanding to include encryption capabilities for either launching ransomware attacks or concealing malicious activities. Its operators have access to a central interface to monitor the status of the botnet and tailor individual samples.
This new trojan highlights the growing trend of cybercriminals taking advantage of the MaaS business model and the need for increased security measures to protect against such threats. Financial institutions should be aware of the Nexus trojan and take proactive steps to protect their customers. Additionally, users should be vigilant when downloading applications and should always ensure that their devices are up to date with the latest security patches.
