The poisoned version of FMWhatsapp was found by researchers at Kaspersky. Triadatrojan plants seeds in any Android device it infects that allow the hackers to install other malware as well. Triadatrojan isn't harmful in and of itself but the hackers have seen fit to bundle the XHelper trojan with the malware.
In addition to providing the promised features, it also installs the Triadatrojan malware. It's somewhat hard to detect because the poisoned mod does what it promises. Hackers have hijacked this legitimate and helpful mod. It promises to improve the WhatsApp user experience by improving user privacy, giving access to custom chat themes, emoji packs from other social networking sites, app locking via a customizable PIN, and more. Are you a WhatsApp user? If you are you may have heard of the FMWhatsApp mod.
