Using the Hak5 Shark Jack Display for authorised Ethernet drop-box labs in Sri Lanka — OLED workflows, SharkLink ideas, and ALFA Network LK pricing.

The wall jack nobody documented
Imagine this: a university NOC in Peradeniya swears VLAN 40 is isolated. Your SOW lets you prove it from two labelled ports during a change window. The Shark Jack Display is built for that kind of short, honest Ethernet story — payloads and results on a tiny OLED, without unfolding a full laptop every time.
ALFA Network LK price: LKR 63,000 (VAT inclusive) for the Display model.
Why on-device UI helps
Hak5 ships interactive DuckyScript + Bash, Linux/SSH, Cloud C² options, built-in payloads, USB-C charging, and SharkLink™ exercises between two Displays. Juniors learn faster when the box itself shows the ping/scan outcome instead of hiding it in a terminal they are still afraid of.
Kit pairing
- Two Displays if you want SharkLink segmentation checks
- Packet Squirrel Mark II when you need true inline MITM between two cable faces
- Plunder Bug for simple tap-into-Wireshark homework
Tips
- Photograph the wall plate ID before and after
- Charge fully; 30-minute-class runtime means plan the window
- Exit attack mode cleanly — leaving scans running is how you earn angry tickets
- Keep a “ports in scope” printout in the bag
FAQ
Display vs Cable vs classic?
This ALFA listing is the Display model. Confirm if you specifically need Cable form factor.
Will it break production?
Any Ethernet tool can, if you ignore change process. Use maintenance windows.
Cloud C² mandatory?
No.

Legal and ethical use
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.
