What your HDMI cable might be teaching attackers: Screen Crab labs

Share

Running Hak5 Screen Crab awareness and physical labs the right way — consent, loot hygiene, Cloud C² notes, and ALFA Network LK pricing.

The monitor cable nobody audits

Physical walkthroughs love locks and badges. They forget the HDMI lead behind the CFO’s monitor. The Screen Crab is Hak5’s inline HDMI capture implant — screenshots or MPEG4 to MicroSD, optional Wi-Fi/Cloud C² streaming, lag-free passthrough. Used wrong, it becomes a privacy incident. Used right, it upgrades cable hygiene overnight.

ALFA Network LK price: LKR 132,500 (VAT inclusive).

Authorised scenario

For example, an accounting firm in Colombo 07 asks for a desk audit demo on a spare monitor and lab PC. You seat the Crab, capture a benign spreadsheet, show how invisible the inline device is, then inventory every display cable in the executive area. Personal devices stay out of the exercise.

Why it hits harder than a slide

People understand “something sat between my PC and my screen.” Hak5’s Full HD class capture, config-via-text-file simplicity, and Cloud C² live view make the story concrete for managers who do not read PCAPs.

Kit pairing

  • Key Croc for keyboard-path contrast
  • Camera for before/after cable photos
  • Locked evidence pouch for MicroSD cards

Tips

  • Lab accounts only — never capture real client data “because it was handy”
  • Disable LED/button when asked
  • Encrypt and wipe media after reporting
  • Match cable seating to the room diagram on handback

FAQ

Does it work beyond 1080p?

Hak5 documents 1080p-class support with compatibility notes for other modes — verify on your display path in the lab first.

Is video mode always on?

Configurable — images by default in typical setups; confirm config.txt.

Can marketing film the demo?

Blur loot. No live customer screens.

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.
