Kaspersky has warned users about the dangers of malicious WhatsApp knockoff apps YoWhatsApp and WhatsApp Plus. Although both appear to offer the same functionalities as the real WhatsApp, they are reported to be able to download the Triada Trojan to smartphones, and steal legitimate WhatsApp’s access keys, thereby giving attackers access to the user’s real WhatsApp account.
The advice is not to visit suspicious websites, and not to use unofficial clients for messaging apps, or to download hacked versions of programs via torrents.
