Verdict:	Malicious activity
Threats:	Dridex is a very evasive and technically complex banking trojan. Despite being based on a relatively old malware code, it was substantially updated over the years and became capable of using very effective infiltration techniques that make this malware especially dangerous. Trojans are a group of malicious programs distinguished by their ability to masquerade as benign software. Depending on their type, trojans possess a variety of capabilities, ranging from maintaining full remote control over the victim’s machine to stealing data and files, as well as dropping other malware. At the same time, the main functionality of each trojan family can differ significantly depending on its type. The most common trojan infection chain starts with a phishing email.
