USB

How it works

• Memory sticks carry files and sometimes malware.
• Unknown sticks found in a car park are a classic trap.
• Some organisations block storage over USB entirely.
• Charging from public ports can expose a phone, so carry your own plug.

What can go wrong (example scenario)

A bookkeeper plugged in a branded memory stick left at a trade show. It carried malware that began stealing files from her computer.

How WILDCARD handles it

Workstation Defender watches for malicious behaviour on business computers, including what runs from a plugged-in stick.

• A clinic blocks personal memory sticks on reception computers.
• An office hands out encrypted drives for travel.
• A staff member hands an unknown stick to IT instead of using it.

A question owners ask

Can I use a memory stick someone gave me?

Treat it as unsafe. Ask your IT provider to scan it or use a shared link instead.
