New spamming campaign has been observed by TrendMicro that is targeting WhatsApp users. The spam is very similar to notifications been sent by WhatsApp that include link to the voice email recorded in case that some one wanted to leave a voice message for you. in order to play the recorded message victim needs to click on the “play” button which obviously leads to a malicious website.
The website directly alert visitors that they are using an outdated browser so they need to download and install updates. For windows users they are going to download browser_update_installer.jar a java application that is detected as J2ME_SMSSEND.AF while on Android recommended upgrade by cybercriminal is browser_update_installer.apk that is ANDROIDOS_OPFAKE.CTD malware.
