During routine control analyses we noticed that some older smartphones are having problems with malware. This finding was also confirmed by individual customers after enquiries were made. We immediately started investigating the incident intensely by working closely with IT forensic experts and the responsible authorities. In the meantime we were able to identify a solution to the problem.
Only older smartphone models of the GS100, GS160, GS170, GS180, GS270 (plus) and GS370 (plus) series are potentially affected.
Not affected by this incident are the smartphone models of the GS110, GS185, GS190, GS195, GS195LS, GS280, GS290, GX290, GX290plus, GX290 PRO, GS3 and GS4 series.
According to our latest information only some devices from the affected product lines were infected. Only devices on which the software updates provided by Gigaset in the past were not carried out by the user are affected. Malware was installed on these devices by a compromised server belonging to an external update service provider.
Gigaset took immediate action and contacted the update service provider. The update service provider also took immediate action and confirmed to Gigaset that the infection of smartphones could be stopped on 7 April.
Measures have been taken to automatically rid infected devices of the malware. In order for this to happen the devices must be connected to the internet (WLAN, WiFi or mobile data). We also recommend connecting the devices to their chargers. Affected devices should automatically be freed from the malware within 8 hours.
