Verdict:	Malicious activity
Threats:	Pony is a malware with two main functions — stealing information and dropping other viruses with different tasks on infected machines. It has been around since 2011, and it still actively attacks users in Europe and America. 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.
