项目历史

The project grew out of NTA Monitor research into UDP retransmission backoff fingerprinting. Roy Hills' 2003 white paper explains the observation that many UDP services, including IKE, leave retransmission timing decisions to implementers, creating measurable patterns that can identify VPN products.

ike-scan v1.0 was the initial public release in the project's NEWS file. Subsequent releases expanded platform support, added Windows binaries, accumulated vendor ID and backoff fingerprints, and added psk-crack for aggressive-mode pre-shared-key material captured by ike-scan.

Version 1.9 marked a major feature expansion: IKEv2 packet support, NAT traversal, source IP spoofing on raw-socket systems, stdin dictionaries for psk-crack, Vendor ID fingerprinting, and improved pseudo-random packet generation. Version 1.9.4 moved development from an internal SVN repository to GitHub.

采用历史

ike-scan became a standard package for VPN assessment work because it targets the exposed UDP/500 and UDP/4500 surfaces that often sit at network borders. The input metadata shows packaging in Homebrew, Debian, Ubuntu, MacPorts, and Nix, and the README documents builds on Linux, BSDs, Solaris, macOS, Cygwin, and several older Unix systems.

使用方式

Operators use ike-scan to send IKE phase-1 probes to one or many targets, list responding hosts, inspect transform support, collect Vendor ID payloads, and optionally measure retransmission backoff with --showbackoff. In aggressive mode, --pskcrack output can feed psk-crack for dictionary or brute-force testing of captured pre-shared-key hashes.

为什么软件包爱好者会关心

The package is significant because it packages a specific security-research technique, not just a generic network scanner. Its data files, including ike-backoff-patterns and ike-vendor-ids, are part of the value: they turn timing behavior and vendor payloads into repeatable fingerprints that can be updated as products change.

• ike-scan sits beside packet tools such as tcpdump and broader scanners such as Nmap, but its closest related artifact is its own UDP backoff fingerprinting paper. Its psk-crack companion makes it part scanner and part focused IPsec assessment toolkit.
