Verdict:	Malicious activity
Threats:	Agent Tesla is spyware that collects information about the actions of its victims by recording keystrokes and user interactions. It is falsely marketed as a legitimate software on the dedicated website where this malware is sold. Agent Tesla ist eine Spyware, die Informationen über die Aktionen ihrer Opfer sammelt, indem sie Tastatureingaben und Benutzerinteraktionen aufzeichnet. Sie wird auf der speziellen Website, auf der diese Malware verkauft wird, fälschlicherweise als legitime Software vermarktet. 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. Remote access trojans (RATs) are a type of malware that enables attackers to establish complete to partial control over infected computers. Such malicious programs often have a modular design, offering a wide range of functionalities for conducting illicit activities on compromised systems. Some of the most common features of RATs include access to the users’ data, webcam, and keystrokes. This malware is often distributed through phishing emails and links. 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.
