Cerberus banking Trojan disguised itself as a genuine app in order to access the banking details of unsuspecting users and is targeting users in Spain. It made to the google store as a ‘Genuine APP” posed as a Spanish currency converter called “Calculadora de Moneda”. The app did not show any signs of harm after being approved on the play store and after months of gaining trust of the users and downloads, the app then triggered dormant code that became a dropper for the Cerberus Trojan. Once executed, the APK dropped Cerberus, a relatively new Trojan that has been in circulation since June 2019.
The malware creates an overlay across existing banking and financial apps. Cerberus will lurk in the background, waiting for a user to input their account credentials, of which this information is then stolen and sent to the attacker’s C2. The app is sophisticated enogh to read one time password (OTP) as well as grab two-factor authentication (2FA) details. These security measures are intended to further protect our online banking sessions.
