  "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.",

Many variants incorporate proxy networks, domain fronting, or cloud services (such as Microsoft Graph API, Google Drive, or Telegram) to masquerade C2 channels, bypassing traditional signature-based egress filtering."
