A new variant of the Emotet Trojan has appeared and is spreading over Wi-Fi networks.

Trojan’s mutation can use the wlanAPI interface to spread onto devices connected to the given Wi-Fi network. Emotet has the ability to collect data on all wireless networks, and even worse, is able to jump from one Wi-Fi network to another.

According to the Komputer Świat portal, Emotet uses a brute-force attack to enter selected network, after which it attempts to guess the password and gain access to the system disk. Trojan can steal the victim’s personal data or install ransomware.

Remember that a good password is essential in such cases.
