How to Prevent Point of Sale Malware like that Which Happened at Target

Everyone remembers the Target point of sale malware situation that occurred in 2014. There was a massive data breach that exposed financial and personal information on over 110 million customers. It occurred because malicious software was found in the POS system at the checkout counters. POS security is a necessity and we at Comodo understand the difficulties that companies face. You don’t want to be in the news because of such a horrible problem. Just imagine all the legal issues and loss of customer loyalty from something like that.

What Happened?

Target POS systems were infected with a type of memory-scraping malware, which parses the data that’s briefly stored in the memory of POS devices. By doing so, the point of sale malware can steal the data stored on the magnetic stripe the moment it is swiped at the terminal before it can be encrypted and placed in the safety of the system memory.

The Target point of sale malware had been on the server for almost an entire year, but none of the antivirus tools that were employed by the company caught the virus or noticed that it was malicious. You see, hackers can customize their attacks to avoid detection by using regular antivirus or antimalware software.

What to Do

You have a few steps that you can take to prevent these attacks on your own company, including:

  • Review accounts and check password complexity. Change default and weak passwords and do so frequently.
  • Check firewalls and remote connection logs to see if foreign IP addresses logged in successfully. If there was no reason for the access, consider the activity to be suspicious.
  • Review running processes for malware by identifying the path and name.
