  "description": "Spyware:Win32/Logicielsespions (French for 'Spyware') is a generic detection for malicious software designed to secretly monitor and collect information about a user, their computer, or their browsing habits, and send this data to a third party. This broad category can range from aggressive tracking adware to highly sophisticated keyloggers (`T1056.001`) and infostealers (`T1552`).<br><br><b>Understanding Logicielsespions (Spyware)</b><br>To an end-user, the infection is often invisible, though they may notice system slowdowns or unexpected network activity. For a SOC analyst, a spyware detection indicates a breach of confidentiality. The severity depends entirely on *what* the spyware is collecting—is it just tracking browsing habits for ad targeting, or is it stealing corporate VPN credentials and session cookies?<br><br><b>Execution and Data Capture Mechanics</b><br>Spyware often arrives bundled with freeware (`T1189`) or via deceptive phishing links (`T1566.002`). Once installed, it establishes persistence (usually via Registry Run keys or hidden scheduled tasks). It operates in the background, employing various techniques to harvest data: hooking APIs to log keystrokes (`T1056.001`), taking periodic screenshots (`T1113`), or directly accessing browser profile directories to extract `logins.json` and `Cookies.sqlite` (`T1552.001`). The stolen data is then exfiltrated via HTTP POST or SMTP to an attacker-controlled server (`T1041`).<br><br><b>Indicators of Compromise & Impact</b><br>The impact ranges from privacy violations to total credential compromise. Host-based IoCs include EDR alerts for suspicious API hooking (e.g., a non-standard process injecting into `explorer.exe`), unauthorized access to browser profile directories, and the presence of hidden, rapidly growing log files in `%Temp%`. Network IoCs involve regular, outbound HTTP/HTTPS or SMTP traffic to low-reputation domains, often containing encrypted or encoded payloads.",
