Key Croc overview for authorised physical assessments — hardware highlights, ethics, sourcing questions for Sri Lanka.

What it is
Key Croc is Hak5’s keyboard-inline pentest implant. It can log keys, match keywords, and trigger payloads — including network paths — when physical access is explicitly authorised.
What it is actually used for
- Physical red-team keyboard inline scenarios
- Demonstrating keyword-triggered escalation
- Detection labs around unexpected HID composites
Key specs and facts
- Quad-core ~1.2 GHz ARM and ~8 GB SSD (Hak5)
- 2.4 GHz Wi-Fi
- HID/Ethernet/serial/storage emulation as described by Hak5
- Text-file style configuration workflows
- Optional Cloud C2 in Hak5 ecosystem
Who it suits / who should pick something else
Only for engagements with physical-access clauses. Otherwise start with policy training, not implants.
Practical setup notes
- Photograph chain-of-custody
- Disable Wi-Fi when RF is out of scope
- Never leave devices after the window closes
How I talk about these tools locally
Most Sri Lankan companies I work with do not need a full Hak5 suitcase on day one. They need one or two devices tied to a written lesson or SOW, plus the discipline not to “just try it” on the office SSID. If you are building a teaching kit, write the learning outcome first (“show USB HID trust”, “show Ethernet dropbox risk”) and only then pick the SKU.
Legal and ethical use
Use these tools only on systems you own or systems covered by written authorisation. 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 the use case is unclear, pause and get counsel.
FAQ
Legal to own?
Use is the risk — authorisation required.
Internet needed?
Not for all local payloads.
Power?
USB inline — plan cabling.
Sourcing?
WhatsApp Dishan.
Interested in Sri Lanka?
ALFA does not currently stock this as a standard catalogue line, and I am not listing a local LKR price here. If you need it for authorised testing or training, message Dishan on WhatsApp at +94 75 255 0704 and ask about sourcing. Include a short note on the engagement or lab use case so the reply is useful.
Documentation habit
Whatever you buy, keep a folder with: purchase date, serial/MAC, firmware hash, and the engagement or class where it was last used. That habit matters more than owning every SKU on this list.
Field notes from teaching
I keep coming back to the same failure pattern: people buy the tool before they write the rule. If your team cannot explain, in one paragraph, which systems are in scope and who signed that scope, the device should stay in the cupboard. Sri Lankan SMEs especially benefit from small, boring kits — one radio, one HID trainer, one written lab SSID — used every month until the muscle memory sticks.
When you ask me about sourcing an item ALFA does not shelf as standard stock, say whether you need a single unit for a named test or a classroom set. Lead times and import paperwork differ. I will not invent a local VAT-inclusive price here for non-catalogue gear; we talk that through on WhatsApp with the vendor quote in hand.
Also budget time for detection. Every offensive demo should end with the control that would have made the demo fail: USB allow-listing, 802.1X on wall jacks, DHCP snooping, cable inventory, whatever fits. Tools without that closing loop turn into theatre.
