Vending machines are a prime target for hacking attempts, and while it may seem low-stakes to manufacturers if a hacker steals a soda, stealing a week's worth of transaction information is a much bigger problem. There is no universal method for hacking a vending machine, as it depends on the type of machine and what the hacker is after. Older machines may be susceptible to physical hacks, such as rocking the machine back and forth, or using a coin with tape wrapped around it to make it seem more valuable. Modern machines are often resistant to these types of hacks, but they may still be vulnerable to firmware mods or pass-through devices that can alter information sent through ethernet cables. Hackers may also disconnect the network cable during a transaction, preventing the machine from confirming that the payment card has any funds. While there are risks associated with hacking hospital vending machines, there are also potential rewards, such as free snacks or drinks, or even the card numbers and PINs of users.
Characteristics and Values Table for Hacking a Hospital Vending Machine:
| Characteristics | Values |
|---|---|
| Motivation | Free food and drinks, challenge, financial gain, or stealing sensitive data |
| Methods | Coin and tape trick, brute-force physical hacks, exploiting software vulnerabilities, disconnecting network cables, firmware mods, pass-through devices, credit card skimmers |
| Machine Types | Coin-operated, credit/debit card, contactless (RFID, NFC) |
| Security Measures | Bolting machines to the floor, using tipping sensors, securing cables, avoiding tubular pin locks |
| Risks | Stealing, financial loss, data misuse |

Exploiting software vulnerabilities
Another method is to use a rooted phone to dig for information. This can be done by making the *.apk debuggable by editing the AndroidManifest.xml file and adding the android: debuggable="true" property to the application
Vending machines with ID card payment options are also vulnerable to hacking. A hacker can swipe their ID card, disconnect the ethernet cable, and then make their snack choice, avoiding the charge as the machine cannot determine the price of the snack without the connection.
To prevent these types of hacks, vending machine manufacturers should work closely with cybersecurity experts to identify potential vulnerabilities and implement robust security measures. Regular maintenance and monitoring practices are also essential, including routine inspections for physical tampering or unauthorized modifications. Keeping firmware and software up-to-date and promptly addressing security patches can significantly reduce the vulnerability of vending machines to hacking attempts.

Using a coin and tape
Firstly, take a small coin and wrap layers of foil over it to make it seem bigger and more valuable. Alternatively, you can use electrical tape or clear tape instead of foil. This will make the machine think that you have inserted a larger coin, and it may give you change or a product in return.
Another method is to attach a piece of tape to a dollar bill. Insert the bill into the machine, and once the machine detects the bill and tries to pull it in, the tape will prevent it from being pulled in further. The machine will assume that payment has been made and will dispense your snack without taking your money.
A more advanced version of this hack is known as "stringing". Tie a piece of string or tape to a coin and insert it into the machine's slot. Gently tug on the string while simultaneously pressing the button for your desired snack. With a bit of luck, both the coin and the treat will be released at the same time.
These methods may not work on modern vending machines, which have become more sophisticated in fraud prevention. Older machines that still rely on physical coins rather than electronic payments may be more susceptible to these hacks.

Disconnecting network cables
To successfully execute this hack, it is essential to understand the vulnerabilities of the specific vending machine model. While modern machines have improved security measures, some older models may have easily accessible cables, making them susceptible to this type of hack.
When attempting to disconnect the network cable, it is crucial to act swiftly during the transaction. By unplugging the cable at the precise moment, the machine becomes unable to complete the payment verification process, resulting in the release of the selected item without deducting any money.
It is worth noting that this method may not work on all vending machines. Some machines might have security measures in place, such as locking ethernet cables or encrypting network traffic, making it challenging to simply disconnect the cable. Additionally, some machines might have backup systems or alternative verification methods that can detect and prevent such hacks.
To enhance security and prevent hacking, vending machine manufacturers should consider implementing robust measures. This includes securing cables to prevent easy access, using secure locks, and encrypting data transmitted over networks. Regular security audits and collaborations with cybersecurity experts can also help identify vulnerabilities and strengthen protection against hacking attempts.

Firmware mods
Vending machines are a prime target for hacking attempts as they are often left unattended for long periods of time. While hacking a hospital vending machine may seem like a low-stakes endeavour, a hacker could potentially steal sensitive financial data, such as credit card numbers and PINs.
To prevent firmware manipulation, it is important to regularly update firmware and software versions and promptly address any security patches or updates. Additionally, it is recommended to have a reputable security consultant audit the software to identify vulnerabilities before they can be exploited.
Another way to protect against firmware mods is to ensure that any cables entering the machine come up through the base rather than the back, where they can be easily accessed and manipulated. It is also crucial to choose card machine vendors with a long track record of no security issues and to get insurance against any potential failings.
While no vending machine is completely foolproof, implementing these security measures can significantly reduce the vulnerability of the machine to firmware mod attacks.

Brute-force physical hacks
Modern vending machines are constructed to be resistant to brute-force physical hacks. However, there are still ways to physically hack a vending machine. One way is to rock the machine back and forth to shake the goods loose. Another method is to smash into the machine, which is a more aggressive approach.
To prevent these types of hacks, vending machines should be bolted to the floor to prevent tipping. A good tipping sensor should not be able to be disabled by a magnet or other external device. Any cables entering the machine should come up through the base, not through the back where they can be easily accessed and manipulated.
In addition to these preventive measures, it is important to avoid using tubular pin locks as they are not very secure. It is also recommended to regularly inspect the machines for any signs of physical tampering or unauthorized modifications.
- Using a coin and a piece of tape or electrical tape to make it seem bigger and more valuable.
- Using a coin with layers of foil wrapped around it to make it seem bigger.
- Using a paper or cardboard coin, which is likely to only work on older vending machines.
- The old coin-and-string trick, where you stick tape to one end of a bill, insert it into the machine, and then pull it out after the machine has registered the dollar amount.
