Verdict:	Malicious activity
Threats:	Hawkeye often gets installed in a bundle with other malware. This is a Trojan and keylogger that is used to retrieve private information such as passwords and login credentials. This is an advanced malware that features strong anti-evasion functions. A keylogger is a type of spyware that infects a system and has the ability to record every keystroke made on the device. This lets attackers collect personal information of victims, which may include their online banking credentials, as well as personal conversations. The most widespread vector of attack leading to a keylogger infection begins with a phishing email or link. Keylogging is also often present in remote access trojans as part of an extended set of malicious tools. A loader is malicious software that infiltrates devices to deliver malicious payloads. This malware is capable of infecting victims’ computers, analyzing their system information, and installing other types of threats, such as trojans or stealers. Criminals usually deliver loaders through phishing emails and links by relying on social engineering to trick users into downloading and running their executables. Loaders employ advanced evasion and persistence tactics to avoid detection. 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.
