Start with visibility: Plunder Bug LAN tap for honest packet labs

Share

A calmer on-ramp to Ethernet capture with Hak5’s Plunder Bug — Wireshark classrooms, change tickets, and ALFA Network LK pricing in Sri Lanka.

Not every lesson needs a full MITM box

New analysts often jump straight to “evil” inline tools. Most first wins come from seeing traffic on a link they are allowed to touch. The Plunder Bug is Hak5’s pocket 10/100 LAN tap with USB-C convenience and scripts for Windows, Mac, and Linux — a calmer on-ramp into Wireshark.

ALFA Network LK price: LKR 66,500 (VAT inclusive).

Authorised scenario

To illustrate: a campus blue team in Moratuwa learns to capture a lab VoIP phone’s DHCP and DNS exchange through the Bug, then write a short findings note. No production core switches. No silent taps on lecturer laptops.

What Hak5 gives you to teach

Auto-negotiating Fast Ethernet, ASIX AX88772C chipset, USB-C tap/power, and cross-platform connection scripts for passive or active styles of work. It will not replace a proper SPAN port when the enterprise already offers one — and that honesty is part of the lesson.

Kit pairing

  • Packet Squirrel Mark II when payloads and MITM are in syllabus week two
  • Cheap spare patch cords so you are not borrowing the client’s last blue cable
  • A shared Wireshark profile for the class

Tips

  • Ticket before breaking any production patch
  • Keep captures short and purpose-bound
  • Name pcap files with date + port ID
  • Teach negotiation quirks on a lab switch first

FAQ

10/100 only?

Yes — Fast Ethernet class per Hak5. Plan accordingly on gig-only fantasies.

Active vs passive?

Hak5 describes both styles; start passive in class.

Why not always SPAN?

SPAN is great when you have it and permission. The Bug teaches copper-path thinking when you do not.

These tools belong in authorised assessments, lab practice, and training — not casual tinkering on networks that are not yours.

In Sri Lanka, unauthorised access to computer systems can engage the Computer Crimes Act No. 24 of 2007. This post is practical product guidance, not legal advice. If you are unsure whether a test is allowed, get written permission first and talk to counsel who knows local law.

Only use this gear on systems you own, or on systems where a named client has given you written authorisation that covers the methods you plan to run.
