  "description": "TrojanDownloader:Win32/Gofot is a persistent, heavily obfuscated trojan designed to breach endpoint defenses and securely deliver secondary, high-severity payloads like ransomware, banking trojans, and botnet agents.<br><br><b>Understanding Gofot</b><br>To an end-user, a Gofot infection is typically invisible until the devastating secondary payload executes. For threat intelligence analysts, Gofot is a critical staging mechanism. It functions as an 'Initial Access Broker' tool. Its primary objective is to securely bypass endpoint defenses, profile the infected machine to ensure it is not a sandbox, and reach out to a Command-and-Control (C2) server to pull down the final, destructive payload.<br><br><b>Execution and Evasion Strategies</b><br>Gofot is commonly distributed via massive malspam campaigns containing weaponized attachments (like ZIP files or Office macros) or through exploit kits. Upon execution, it utilizes heavy packing and dynamic API resolution to evade static antivirus signatures. It drops a randomized executable into the <code>%Temp%</code> directory. It establishes persistence by creating a hidden scheduled task or modifying the Registry Run keys. Gofot frequently injects its downloading routine into legitimate system processes (like <code>explorer.exe</code> or <code>svchost.exe</code>) to mask its outbound network traffic.<br><br><b>Indicators of Compromise (IoCs)</b><br>Threat hunters should investigate EDR alerts related to 'Suspicious Process Injection' or 'Anomalous Child Process Spawning'. Network logs will often reveal Gofot reaching out to compromised domains using encrypted HTTPS traffic. The presence of unexpected, hidden scheduled tasks designed to execute randomly named, highly entropic binaries in the user's profile is a strong IoC. Memory analysis is necessary to extract the injected downloader modules and determine what payloads were requested.",

  "containment_steps": [
    "Isolate the endpoint immediately to prevent Gofot from downloading and executing its secondary payloads (e.g., ransomware).",
    "Audit the Windows Task Scheduler and Registry Run keys to identify and remove the Gofot persistence mechanisms.",
    "Review firewall and proxy logs to identify the C2 domains Gofot attempted to contact, and block them enterprise-wide.",
    "Capture a live memory image (RAM dump) to extract the injected Gofot modules and identify the secondary payloads."

  "what_to_avoid": [
    "Do not close an incident simply because the initial Gofot dropper was quarantined; always verify if secondary payloads were downloaded.",
    "Avoid relying solely on manual file deletion, as the injected processes will likely just recreate the dropped binaries."
