Read the full Proactive Threat Detection explanation →

A SOC analyst is reviewing logs and finds that a server is attempting to connect to multiple external IPs on port 445. What is the most likely cause of this behavior, and what is the primary threat?

Trap 1: A misconfigured web application load balancer

Load balancers typically use load-balancing specific ports or 80/443.

Trap 2: Standard user traffic to a file share

User traffic is typically directed to a single known file server, not multiple IPs.

Trap 3: Normal background updates for the operating system

Windows updates generally use ports 80/443, not 445.

A
Lateral movement attempt using an automated exploit tool
Internal systems scanning for SMB are a primary indicator of spreading malware or lateral movement.
B
A misconfigured web application load balancer
Why wrong: Load balancers typically use load-balancing specific ports or 80/443.
C
Standard user traffic to a file share
Why wrong: User traffic is typically directed to a single known file server, not multiple IPs.
D
Normal background updates for the operating system
