"title": "Suspicious execution of hidden file",
"description": "A hidden file has been launched. This activity could indicate a compromised host. Attackers often hide files associated with malicious tools to evade file system inspection and defenses.",
"recommendedActions": "Collect artifacts and determine scope\n�\tReview the machine timeline for suspicious activities that may have occurred before and after the time of the alert, and record additional related artifacts (files, IPs/URLs) \n�\tLook for the presence of relevant artifacts on other systems. Identify commonalities and differences between potentially compromised systems.\n�\tSubmit relevant files for deep analysis and review resulting detailed behavioral information.\n�\tSubmit undetected files to the MMPC malware portal\n\nInitiate containment & mitigation \n�\tContact the user to verify intent and initiate local remediation actions as needed.\n�\tUpdate AV signatures and run a full scan. The scan might reveal and remove previously-undetected malware components.\n�\tEnsure that the machine has the latest security updates. In particular, ensure that you have installed the latest software, web browser, and Operating System versions.\n�\tIf credential theft is suspected, reset all relevant users passwords.\n�\tBlock communication with relevant URLs or IPs at the organization�s perimeter.",
