This campaign was first identified at the end of 2021, with the attackers impersonating the legitimate cleaning service Maid4u. Distributed through Facebook ads, the campaign tempts potential victims to download Android malware from a malicious website. It is still ongoing as of the publication of this blogpost, with even more distribution domains registered after its discovery. In January 2022, MalwareHunterTeam shared three more malicious websites and Android trojans attributed to this campaign.

∗∗∗ SpringShell Detector - searches compiled code (JAR/WAR binaries) for potentially vulnerable web apps ∗∗∗
---------------------------------------------
The SpringShell vulnerability may affect some web applications using Spring Framework, but requires a number of conditions to be exploitable. One specific condition which may be rather rare (and therefore render most applications non-exploitable in practice) is the existence of Spring endpoints which bind request parameters to a non-primitive (Java Bean) type. This tool can be used to scan compiled code and verify whether such endpoints exist in the codebase.

Einen Schwachpunkt hat dieser Ansatz aber: Der Ausgangspunkt von einer BITB-Attacke ist eine Phishing-Website, die das OAuth-Anmeldeverfahren mit dem Fake-Fenster anbietet. Dahin müssen Betrüger Opfer erst mal locken, ohne dass Verdacht aufkommt.
