A Brief Overview of the Target Data Breach
The breach originated through a third-party vendor — a heating, ventilation, and air conditioning (HVAC) company. Attackers infiltrated Target’s internal network using stolen credentials from this vendor, exploiting wireless network vulnerabilities and weaknesses in Target’s supply chain security.
Once inside, the hackers deployed malware designed to harvest credit card data from point-of-sale (POS) systems. Within weeks, millions of credit and debit card numbers had been stolen and later sold on the dark web.

How Did the Attackers Gain Access?
Hackers targeted the HVAC vendor first because smaller companies often have weaker security. After gaining access to the vendor’s systems, attackers used stolen login credentials to remotely access Target’s corporate network.
This attack highlights the importance of penetration testing lab setup and training third-party vendors in cíber segurança best practices.

The Role of Poor Network Segmentation
Once the attackers accessed Target’s network, they found that different systems weren’t adequately segmented. This lack of segmentation allowed them to move laterally across the network, accessing sensitive customer information with relative ease.
Understanding the OSI model in network security e TCP/IP basics for hackers is crucial for spotting these kinds of flaws before hackers exploit them.

Malware Deployment on POS Systems
After navigating Target’s network, the hackers installed malware specifically designed to collect credit card information at the point of sale.
This malware captured data from the card’s magnetic stripe in real-time and transmitted it to external FTP servers controlled by the hackers.
