Introduction To POS Systems

POS Attacks

What is the common thing you see when you go to a restaurant, a clothing shop, and a grocery store? The answer is a POS or point-of-sale machine. This records and facilitates the transaction between the seller and the buyer. This includes getting the credit card info from the buyer and charging it. This transaction system is prone to POS attacks.

You can see a POS machine anywhere a business transaction would occur. The security of these POS systems should always be a priority. What would happen if someone gets your credit card number and bank account details? They can pay for goods and services using your credit card number without your knowledge.

The list of malicious things that they can do is long. These cybercriminals are always on the lookout for any sign of weakness. They will exploit this weakness to their advantage. So how do you stop POS attacks and POS breaches from happening?

You will learn about the most common types of POS attacks. You will later learn how to counter these POS system attacks with the help of SecureBox.

The Threats To POS Systems

A POS data breach happens because of many reasons. One is a lack of awareness or knowledge about cybersecurity. Another factor is the poor implementation of security policies and procedures. You will fall victim to POS attacks if you don’t have any form of security in place.

Here are the three most common types of POS attacks:

1. Keystroke recorders

POS attacks are successful with the help of keystroke recorder programs. These are also known as keyloggers. This is a kind of spyware program that records every keystroke you make. Spyware also falls under the category of malware or malicious software.


The attacker will try to install a keylogger in the target POS system or machine. This is possible through email or inserting a USB on the POS machine. In either case, the goal is to inject the malware which is the keylogger into the target machine. Once the installation is successful, the keylogger records every user input. This includes the card swipes on the POS machine.

Credit card numbers and bank account details are then sent to the attacker’s email. Some keyloggers can even take screenshots of your system. All this malware activity happens before the sensitive data undergoes encryption process.

2. Memory dumpers

Successful POS attacks involve the use of memory dumpers as well. This is a kind of malware program that resides in a computer’s memory. When you swipe a credit card, the track data loads into memory.

This contains the cardholder’s name, account and credit card number, and card expiry date. The memory dumper steals this data before the payment application receives it.

3. Network sniffers

POS attacks also involve the use of network sniffer or network sniffing program. This examines the traffic on a network. This tool enables the monitoring and analysis of data packets in real-time.

Both black hat and ethical hackers use a network sniffing program. Network sniffing is like wiretapping in concept. A cybercriminal uses this to listen for any sensitive info like credit card numbers.

You might be wondering now how to counter these POS attacks? You will learn how to defend against these types of threats in the next section.

Protection Against POS Attacks

You have to take into consideration other threats aside from the three. To do this, you need a strong security solution. SecureBox handles various kinds of threats. SecureBox is an award-winning and all-in-one security software.

Here are the features of SecureBox that protects you from POS attacks:

  • SecureBox provides you with keylogger protection. SecureBox utilizes keystroke encryption technology. Every user input undergoes encryption. This is a very strong and reliable feature. The cybercriminal will have a hard time deciphering every encrypted keystroke.
  • SecureBox protects you from POS attacks using memory-scraping programs. Memory scrapers look for sensitive data in memory and steal it. An example of this is the memory dumper program. SecureBox uses application containerization technology. Programs inside this secure container are invulnerable to external threats.
  • SecureBox protects you from POS attacks using network sniffing methods. SecureBox watches over your POS system for any sign of suspicious activity 24/7. SecureBox is an award-winning intrusion detection and prevention program as well.
  • SecureBox not only protects you from POS attacks but it also protects you from the following:

    1. Viruses
    2. Trojans
    3. Worms
    4. Rootkits
    5. Spyware
    6. Adware
    7. Ransomware

SecureBox offers cloud-based malware prevention, detection, and removal.

  • SecureBox also scans your system for vulnerabilities. It has a cloud-based vulnerability scanning feature. This is a very important security feature. This allows you to scan your system for security holes or weaknesses. Cybercriminals love to exploit these security holes. Patching up these vulnerabilities should be a priority.

Those are some of the features of SecureBox that protect you against POS attacks.
