Six indicators that a keylogger might be running on your system.
One. Keystroke lag. A keylogger sitting between the keyboard driver and your application adds latency you can feel.
Two. Inconsistent input — dropped characters, double-typed keys, or keystrokes arriving out of order.
Three. An unfamiliar process with a generic or system-looking name. Check the file path and the digital signature, not just the name. Many keyloggers impersonate svchost or other system services.
Four. Outbound network connections you cannot explain. Keyloggers have to exfiltrate captured data. Use Resource Monitor on Windows or lsof and netstat on Linux and macOS to inspect connections.
Five. Disk activity or CPU usage when the machine should be idle. Logging keystrokes and batching them for upload leaves a trace.
Six. Hijacked browser sessions or account logins from unfamiliar locations. By the time you see this, the keylogger has already done damage.
If you suspect a keylogger is present, do not type passwords into the suspect machine. Boot from clean media, scan from outside the running operating system, and rotate every credential from a device you trust.
