Emotet, the notorious trojan behind a number of botnet-driven spam campaigns and ransomware attacks, has found a new attack vector: using already infected devices to identify new victims that are connected to nearby Wi-Fi networks.

According to researchers at Binary Defense, the newly discovered Emotet sample leverages a "Wi-Fi spreader" module to scan Wi-Fi networks, and then attempts to infect devices that are connected to them.

How Does Emotet's Wi-Fi Spreader Module Work? The updated version of the malware works by leveraging an already compromised host to list all the nearby Wi-Fi networks.

Emotet: From Banking Trojan to Malware Loader Emotet, which was first identified in 2014, has morphed from its original roots as a banking Trojan to a "Swiss Army knife" that can serve as a downloader, information stealer, and spambot depending on how it's deployed.

"Emotet can use this loader-type to spread through nearby wireless networks if the networks use insecure passwords."
