Keylogger definition
A keylogger is software or hardware used to record (log) the keys being pressed on a keyboard, often without the user’s knowledge. While the technology itself is legal, most keyloggers are installed through malware to steal passwords and confidential information.
Real keylogger examples
2007-present: DarkHotel targets people over unsecured hotel Wi-Fi, using false security certificates to prompt victims to “update” their systems with a keylogger.
2015: Hackers stole up to 80 million records from Anthem, a US healthcare insurance firm, after using phishing emails to lure employees into downloading keyloggers.
Stopping a keylogger
