Verdict:	Malicious activity
Threats:	Arkei is a stealer type malware capable of collecting passwords, autosaved forms, cryptocurrency wallet credentials, and files. Stealers are a group of malicious software that are intended for gaining unauthorized access to users’ information and transferring it to the attacker. The stealer malware category includes various types of programs that focus on their particular kind of data, including files, passwords, and cryptocurrency. Stealers are capable of spying on their targets by recording their keystrokes and taking screenshots. This type of malware is primarily distributed as part of phishing campaigns. 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. Vidar is a dangerous malware that steals information and cryptocurrency from infected users. It derives its name from the ancient Scandinavian god of Vengeance. This stealer has been terrorizing the internet since 2018. Malware Trends Tracker >>>
