Security News > 2024 > April > New Wpeeper Android malware hides behind hacked WordPress sites
A new Android backdoor malware named 'Wpeeper' has been spotted in at least two unofficial app stores mimicking the Uptodown App Store, a popular third-party app store for Android devices with over 220 million downloads.
Wpeeper stands out for its novel use of compromised WordPress sites to act as relays for its actual command and control servers, acting as an evasion mechanism.
Abusing WordPress as a C2. Wpeeper's novel C2 communication system is structured to leverage compromised WordPress sites and intermediate relay points, obscuring the location and identity of its actual C2 servers.
Wpeeper can update its C2 servers dynamically through the reception of a related command, so if a WordPress site is cleaned, new relaying points on different sites can be sent out to the botnet.
Using multiple compromised sites across different hosts and locations adds resilience to the C2 mechanism, making it hard to shut down the operation or even disrupt the data exchange on a single infected Android device.
