Banking Trojan Retefe is adopting new WannaCry tricks, adding an EternalBlue module to propagate the malware. The update makes Retefe the latest malware family to adopt the SMBv1 attack against a patched Windows vulnerability. Earlier this year, researchers at Flashpoint observed the TrickBot banking Trojan had added an Eternal blue module as well. Retefe has never reached the scale or reputation of similar Trojans such as Dridex or Zeus, but it is notable for its consistent regional focus in Austria, Sweden, Switzerland, Japan and more recently the United Kingdom.
