port 8383↗

command GET /glob1/↗

• → Detect abnormally long HTTP GET requests (≥3000 characters) sent to port 8383, indicative of the IMail web service buffer overflow exploit attempt. ↗
• → Monitor for connections to TCP port 8383 followed by oversized GET requests, which is the attack vector for crashing the IMail web server. ↗

• · The buffer overflow is triggered via the IMail web service (not SMTP/POP3); ensure port 8383 is specifically monitored or blocked at the perimeter if IMail web service is not required. ↗
