Hak5 O.MG UnBlocker: USB charge-only teaching aid

Product photo: Hak5

What it is

O.MG UnBlocker sits on the defensive/utility side of the O.MG ecosystem: helping illustrate charge-only vs data-capable USB paths. Exact behaviour is SKU-specific — read the product page before teaching it as a control.

What it is actually used for

• Teaching why charge-only adapters matter on untrusted ports
• Travel hygiene demos for staff awareness
• Contrasting blockers with offensive cables in the same curriculum

Key specs and facts

• Compact USB utility form factor
• Intended as a privacy/utility accessory in the O.MG line
• Confirm electrical/data characteristics on the live listing

Who it suits / who should pick something else

Useful in awareness kits. Not an attack platform. Pair with policy, not superstition.

Practical setup notes

• Demo on a sacrificial USB killer? No — use safe lab ports
• Explain limitations honestly (blockers are not magic)

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

Replaces policy?

No.

vs Data Blocker from other brands?

Compare specs; do not assume identical.

Offensive use?

Wrong tool.

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.
