What is the vulnerability being exploited in a USB switchblade?

Whilst USB has made using peripherals and removable storage trivially easy and convenient, there has recently been a discovery of a vulnerability with USB that makes every computer in the world vulnerable. It’s called BadUSB, and you need to know about it.

What can BadUSB do?

BadUSB is an attack that exploits an inherent vulnerability in USB firmware. Such an attack reprograms a USB device, causing it to act as a human interface device; once re-engineered, the USB device is used to discreetly execute commands or run malicious programs on the victim’s computer.

Why is USB bad?

Attackers can use USB drives to infect other computers with malware that can detect when the USB drive is plugged into a computer. The malware then downloads malicious code onto the drive. The most obvious security risk for USB drives, though, is that they are easily lost or stolen.

Why the security of USB is fundamentally broken?

Because BadUSB resides not in the flash memory storage of USB devices, but in the firmware that controls their basic functions, the attack code can remain hidden long after the contents of the device’s memory would appear to the average user to be deleted.

Can you get a virus from a USB port?

An infected computer can spread a virus to a clean USB thumb drive that is inserted. That USB drive will then be spreading the virus onto other computers if the operating system on those machines has an AutoRun-type feature enabled.

How do USB attacks work?

Malicious code — In the most basic of USB drop attacks, the user clicks on one of the files on the drive. This unleashes a malicious code that automatically activates upon viewing and can download further malware from the Internet.

Is my flash drive infected?

Right-click on the USB icon, then left-click Scan for viruses from the drop-down menu. When the Shell Scanner starts, ensure include subdirectory is ticked, and click the green start button (circled below). This will scan your USB drive for any viruses and produce a report like this, which you can then close.

What is a USB port blocker?

Port blockers are visual deterrents that seamlessly fit into a variety of environments and provide a physical barrier to unauthorised access. They are a scalable, easy-to install solution that meet the requirements of any environment, from the smallest businesses, to multinational corporations.

How do I know if my USB has malware?

Are USB ports secure?

A more effective approach uses encryption to protect the confidential information stored on portable devices. This ensures that the data in a flash drive or USB device remains safe in the event of theft or accidental loss. This is where USB encryption comes in.

How do I remove a virus from my USB port?

How to Get Rid of a Virus on Your USB Devices

1. Step 1: Plug the USB into a Computer.
2. Step 2: Run the Command Prompt.
3. Step 3: Find the Drive in the Command Prompt.
4. Step 4: Find Out What the Virus is.
5. Step 5: Disable the Infected Files.
6. Step 6: Delete the Files.
7. Step 7: Scan the USB with an Anti-Virus.

What can you do with a bad USB?

This allows us hackers to reprogram the microcontroller in them to act as a human interface device (HID), e.g., a keyboard, and perform custom keystrokes on our target machine. This scenario is often called an “HID Payload Attack,” since you have to hand over your script to the Bad USB for the execution (more on that later).

How to make your own bad USB flash drive?

It doesn’t require any installation. Just open the tool and hit the “Get USB Flash Drive Information” button while you have your USB inserted into your PC. If your drive uses the Phison 2303 (2251-03) controller, the output should look similar to this:

How can I get information about my USB?

Before starting, we want to make sure our USB uses the supported controller. We can use a program called Flash Drive Information Extractor to gather the required information about our USB. It doesn’t require any installation. Just open the tool and hit the “Get USB Flash Drive Information” button while you have your USB inserted into your PC.

Why are USB flash drives vulnerable to hackers?

Most common USB flash drives are exploitable due to the “BadUSB” vulnerability. This allows us hackers to reprogram the microcontroller in them to act as a human interface device (HID), e.g., a keyboard, and perform custom keystrokes on our target machine.
