DefinitionSpyware (スパイウェア) is information-gathering malware that gets onto a device without the user knowing, quietly collects personal data and activity records, and sends them out.
ExplanationIt often arrives in ways the user does not notice, such as being bundled with free software or installed through a fake prompt. What it collects varies widely, including browsing history and the contacts stored on the device.
AnalogyIt is like a private detective hired to note someone's every move from the shadows and report back. The person being watched has no idea it is happening.
Memory hookA spy's job is not sabotage but bringing information home. Tie the name to that.
