POS Machines and keeping them safe


POS Machine is something that everyone has seen and knows for what purpose it is used. But not everyone has knowledge about how it works or how a malware or hackers can affect a POS Machine.

Point of Sale (POS) machines are used to process card payments at retail locations. These machines are very important from the retail payment point of view because without them it would have been very hard and slow of process the payments in retail places.

Generally, a POS machine process the payment through credit and debit cards in four steps:

Reading the information from the credit/debit card.

Checking whether he funds in the customer’s account are sufficient for the payment or not.

If sufficient funds re there then transferring the amount requested from customers account to the seller’s account.

Lastly recording he transaction details and then printing out a received with all those details.


What Reports says on


POS Malware and Hacking

In 2011 hackers were able to steal credit card data from 80,000 customers because of the POS configuration of Subway were disregarded by the Subway franchisees.

In June 2016, hundreds of Wendy's fast food restaurants had their POS system hacked by an illegally installed malware. Hackers made thousands of fraudulent purchases through the data they stole from various debit and credit cards.

These exploits by-hackers could-only be-made-possible because payment cards were processed through the POS system allowing the malware either to intercept the card data during processing or steal and transmit unencrypted card data that is stored in the system database.


POS Malware

POS Malware is specifically designed for POS terminals and systems with the intention of stealing the information from customer’s banks. When the payment is

being processed credit card data is decrypted in the random access memory (RAM)

of the system. Appears Malware is able to enter into the system through week

security systems and then attack the data-stored-in-the RAM of the system and

then send it an encrypted to the hackers.


Different types of malware

Black POS: this type of Malware is designed for Windows system and

the computers which run on Windows. These do not have offline data extraction

and the stolen data is uploaded to remote servers online.

How to prepare your system from POS

There are three mean ways by which retailers or POS machine manufacturers can and save the system from POS:

Code signing: Code signing is a kind of a cryptographic value assigned to a specific executables as a verifiable check against tempering. This insurance that the system is not tampered with, on the starting of the system.

White listing technology: this technology is used in determining any kind of unauthorized practices that are going on in the system and does stops POS Malware from harming the system. This type of Technology only allows some pre-authorized applications to run on the system.

Chip readers: the chipped cards allow customers to avoid swiping of credit or debit cards. The EMV system in the chipped cards use a kind of technology which changes the data information on every transaction and it becomes more difficult for the hackers to steal the information from credit or debit cards. In short it makes the replication of card data more hard as compared to the magnetic stripes.
