SingTel, M1 and Starhub has warned Android smartphone users that a SMS with a link to a malware could mass-send messages to all contacts in the address book when the downloaded PhotoViewer.apk file installs.
Starhub has since blocked access to the link such that unsuspecting users would not fall prey whereas SingTel and M1 did not indicate if they have done the same. If you have recently seen this SMS and have installed a certain .apk file unknowingly, it is recommended to go through your installed apps and delete away suspicious ones. SingCERT has also provided instructions on how to uninstall the malware.
Although it has been reported that the malware sends SMS, we do not know if there are other damaging functions manifesting within it. If you have thousands of contacts and gotten infected, be prepared as you could be receiving a larger phone bill amount this month.
