Exploit Detected

Detects vulnerability exploitation attempts in AhnLab EPP V3 malware alert logs.

Query

The AhnLab V3 antivirus engine detects exploit files using signatures such as Exploit/Win.CVE-2022-24521.C5317859, Exploit/Win.Generic.C4467937, etc. Therefore, alerts are extracted when the signature value begins with Exploit/. However, Exploit/Win.MagicLineX is excluded because it is detected for the purpose of removing vulnerable software, not as a malicious exploitation attempt.

| search signature == "Exploit/*" and signature != "Exploit/Win.MagicLineX"

Message

  • AhnLab EPP V3 Privilege Escalation Exploit Detected: Host $host_ip, Malware $signature

Field Order

  • _log_time, hostname, host_ip, emp_name, dept_name, signature, file_path, file_status, md5

Threat Analysis

  • The Exploit/ signature family refers to malicious code or exploit files that attempt to abuse vulnerabilities in the operating system or applications for privilege escalation.
  • The presence of this detection indicates that an attacker may have already attempted to elevate privileges within the system or that an exploit payload has been introduced.
  • Some exploits may lead to secondary malicious actions, such as installing additional malware, creating backdoors, or bypassing system protections, making immediate investigation and containment essential.

False Positives

  • Detections may occur when exploit files are legitimately used during vulnerability scanning, penetration testing, or internal red-team activities.
  • Aside from Exploit/Win.MagicLineX, vulnerable software associated with the Korea Internet & Security Agency (KISA) vulnerability cleaning service may also trigger detections.

Response Actions

  • Verify whether the detected file was actually executed, and analyze the file path and creation timestamp to determine if exploitation was successful.
  • Examine system event logs, process creation records, and any signs of privilege escalation to assess the scope of compromise.
  • Check whether similar exploitation attempts have occurred on other endpoints within the same network.
  • Apply the latest OS and application patches, and strengthen EDR/security configurations to block exploitation attempts.
