Kportscan 3.0 Patched Today
Seamlessly processes large CIDR blocks (such as /16 or /8 networks) and accepts complex input lists of disparate IP ranges.
The interface is minimal, allowing the user to:
Both are GUI tools often used in tandem by ransomware gangs. Advanced Port Scanner is generally considered more modern and has better network discovery features, but KPortScan remains popular due to its smaller footprint and prevalence on hacking forums. kportscan 3.0
| Limitation | Impact | Mitigation | |------------|--------|-------------| | No TCP connect scan for localhost | Cannot bypass host firewall rules | Use --force-tcp-connect flag | | Requires root/admin for raw sockets | Not user-friendly | Provide capabilities/CAP_NET_RAW | | IPv6 full subnet scan impossible | User may attempt | Hard limit: abort if >1M targets | | UDP scanning unreliable | Packet loss high | Use retransmission with exponential backoff | | Cloud scanning may violate ToS | Legal risk | Warn user; require --cloud-compliance-ack | | eBPF requires kernel 5.8+ | Legacy systems unsupported | Fallback to raw socket mode |
Threat actors established initial access and uploaded web shells. They deployed to run internal network sweeps. The scan data exposed live servers running RDP. Seamlessly processes large CIDR blocks (such as /16
Run via command line: KPortScan3.exe --script nightly_scan.lua

Analyze traffic for unusual spikes in internal traffic, particularly RDP or SMB traffic originating from workstations or newly exploited web servers.
KPortScan 3.0 is a specialized network scanning utility designed to identify open ports and active services across massive IP address ranges. It belongs to the class of high-speed mass-scanning tools, engineered to process thousands of IP addresses per second.
