Card Breaches On Point of Sale(POS Malware):

Pos Malware is operated by actors ranging from fraudsters to Organized Crime Groups.Most POS malware codes are RAM scrapers that make their way into the target endpoint, focus on reading unencrypted card data in the random access memory (RAM) zone and steal data amassed through the days and weeks of the breach.

One of the most recent POS malware is MajikPOS. Attackers begin by penetrating the target organization’s systems to reach POS endpoints. Usually connected to the endpoint using remote access, either one that’s already installed or one they activate, such as virtual network connection (VNC) or remote desktop protocol (RDP) access.

The connection can be made by stealing or guessing the password.After gaining access, the attackers install the POS malware on the endpoint. From there, the malware executes and continually sends out the stolen data to the attacker’s server.

The United States is the last of the G20 nations to make the shift to more secure chip-based cards, chip-based cards are more expensive and difficult for cybercriminals to counterfeit.

But many financial institutions still not replacing traditional magnetic stripe cards with chip-based cards. According to Visa, 58 percent of the more than 421 million Visa cards issued by U.S. financial institutions were chip-based as of March 2017.
