Point Of Sale System Vulnerabilities

A Point-of-Sale system is a way of doing business between a seller and a buyer. You can see POS machines where business transactions would occur. You can see POS machines in restaurants, at the grocery, and retail stores among others. These have weaknesses also known as a point of sale system vulnerabilities.

A POS data breach occurs when someone gets unauthorized access to sensitive data. This includes credit card numbers and bank account details. Cybercriminals would launch POS system attacks using various methods. They can perform man-in-the-middle attacks on the target POS system. Their malware would try to infect a POS system. Cybercriminals can use social engineering attacks as well.

A POS system is vulnerable to these attacks and other threats. One should look for these point of sale system vulnerabilities before cybercriminals do. You will know about the various point of sale system vulnerabilities and how to prevent them. You will also understand the importance of using SecureBox.

What Are The Different Point Of Sale System Vulnerabilities?

POS malware targets retail stores to steal sensitive data from customers. It works by scanning the memory of a POS system for sensitive data like credit card numbers. The attacker would then receive this data on their email. BlackPOS is an example of a notorious POS malware.

Here’s a sample POS malware list, according to Wikipedia:

  • Rdasrv
  • Alina
  • VSkimmer
  • Dexter
  • BlackPOS
  • Backoff
  • FastPOS
  • PunkeyPOS
  • Multigrain
  • CenterPOS
  • MalumPOS

Your POS system should have protection and prevention capabilities against various threats. Finding the point of sale system vulnerabilities before an attacker does is crucial.

Here are the different point of sale system vulnerabilities:

Outdated software

Outdated software is one of the point of sale system vulnerabilities. An attacker will exploit an existing weakness if it doesn't have any fix yet. A patch contains software fixes and upgrades.

Updating your POS system on a regular basis prevents some threats from happening. A good patch management software can automate this task for you.

Weak passwords

A lot of people use default and weak passwords for various accounts. Cybercriminals have tools that crack weak passwords without exerting any effort. Your password should be strong enough to withstand cracking attacks on it.

A strong password should at least be eight characters long. A strong password should contain alphanumeric characters. It should also contain two lowercase and two uppercase letters. It should also contain special characters. A strong password should not have any connection to you in any way.

Having a weak password is one of the point of sale system vulnerabilities.

No encryption

Data is useless if the attacker can’t make any sense of it in the first place. This is what you get from using encryption. A POS system should encrypt data all the time.

There are a lot of ways to do this. You can start by using end-to-end encryption or E2EE. The basic HTTP plus TLS or HTTPS is very much advisable as well.

HTTPS stands for Hyper Text Transfer Protocol Secure. This is a standard today and there’s a lock icon beside it in the URL of the browser.

SecureBox takes encryption to another level. It uses keystroke encryption technology. Every keystroke undergoes encryption process. This defeats keylogging programs as well. Having no encryption is one of the point of sale system vulnerabilities as well.

No malware protection

A POS system should have protection from various types of malware. The following threats fall under malware category:

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

This is one of the point of sale system vulnerabilities that need the most attention. Cybercriminals always use malware in performing POS system attacks.

They would inject their malware to your POS system in various ways. They could send you an email containing harmful links. Clicking these would install malware in your POS machine.

They can install malware on your POS machine when you are not looking by inserting a USB device. SecureBox is a great antimalware software. It prevents, detects, and removes malware. Say no more to keyloggers, memory scrapers, and phishing attacks!

No firewall protection

Having no firewall is also one of the point of sale system vulnerabilities. This is your first layer of defense against threats.

An attacker would try to infiltrate your POS system in many ways. Countering their infiltration methods thwart most attacks. A firewall does the job very fine.

SecureBox acts as a web application firewall or WAF. It watches your POS system for any sign of suspicious activity 24/7. SecureBox is also an award-winning intrusion detection and prevention software.

Using SecureBox for your POS system also thwarts zero-day attacks. This is one of the point of sale system vulnerabilities which is vital.
