Gigaset mobile devices are being infected with malware that’s being downloaded and installed through a pre-installed system update app. The Update app installs three different versions of a trojan that’s capable of sending SMS and WhatsApp messages, redirecting users to malicious game websites, and downloading additional malware-laced apps. The development was first reported by German author and blogger G..nter Born last week. While the issue seems to be mainly affecting older devices, devices from a handful of other manufacturers appear to be impacted.
