In comparison to most anti-virus or anti-spyware software, the primary difference is that an anti-keylogger does not make a distinction between a legitimate keystroke-logging program and an illegitimate keystroke-logging program (such as malware); all keystroke-logging programs are flagged and optionally removed, whether they appear to be ...

This allows the malware to avoid HTTPS encryption. This method is more effective than keylogger software because it will acquire the user’s credentials even if they are input using virtual keyboard, auto-fill, or copy and paste.

Magic Lantern can reportedly be installed remotely, via an e-mail attachment or by exploiting common operating system vulnerabilities, unlike previous keystroke logger programs used by the FBI. [3] [4] It has been described as a virus and a Trojan horse. It is not known how the program might store or communicate the recorded keystrokes.
