Safety researchers from Cleafy noticed a brand new Android Banking Trojan within the wild earlier this month.

Dubbed “Revive” due to certainly one of its capacity to mechanically restart in case it stops working, the software reportedly belongs to a class of malware designed for persistent campaigns.

Writing in an advisory on Monday, Cleafy defined Revive was developed to focus on particular targets (at present, Spanish banks).

On the identical time, the researchers added that the assault methodologies behind Revive are much like different banking trojans for the reason that malware nonetheless exploits accessibility companies to carry out keylogging actions and intercept SMS messages of the sufferer.

Delivered via numerous social engineering methods, upon set up the Cleafy app would ask customers to simply accept permissions associated to SMS and telephone calls. 

As soon as the permissions have been granted, Revive would then redirect customers to a cloned web page (of the focused financial institution) and immediate them to insert their credentials.

These would then be despatched to the command and management infrastructure (C2) of the menace actors (TAs), alongside any two-factor authentication (2FA) or one-time password (OTP) codes despatched by way of SMS or telephone name by banks.

Lastly, Revive would redirect victims to a generic dwelling web page with hyperlinks to the reputable financial institution web site to keep away from alarming customers.

An preliminary evaluation of Revive’s code confirmed that each of the samples obtained by Cleafy at present have a really low detection charge by Antivirus options (AVs), probably as a result of they’re nonetheless underneath growth.

By way of similarities with current malware, the safety researchers mentioned the malicious actors behind Revive took inspiration from open-source spy ware known as ‘Teardroid’ since each instruments look like based mostly on FastAPI, a Internet framework for growing RESTful APIs in Python, and sections of the code of each malware cases appear to be comparable. 

Nonetheless, the menace actors behind Revive would have then modified it to carry out account takeover assaults (ATO). Due to this distinction, Cleafy categorised Revive as a banking trojan and never merely spy ware.

The invention of Revive comes days after Cleafy upgraded the classification of the BRATA Android malware group to superior persistent menace (APT).
