Abstract
The Home Depot data breach, which occurred in 2014, marked a significant turning point in the
cybersecurity landscape, drawing attention to the increasing prevalence of ransomware and
cyberattacks targeting large-scale retail organizations. This breach exposed the personal and
financial information of over 56 million customers and highlighted the vulnerabilities in the systems
used by major corporations. The attack was attributed to a sophisticated ransomware operation that
gained access through a third-party vendor’s compromised credentials, ultimately enabling
cybercriminals to infiltrate Home Depot’s network. This paper explores the Home Depot breach,
focusing on its relation to the rise of ransomware as a common cyber threat. It delves into the
tactics, techniques, and procedures (TTPs) employed by the attackers, the vulnerabilities exploited,
and the broader implications for the retail industry and cybersecurity at large. Additionally, the study
examines how ransomware has evolved from a relatively niche threat to a significant weapon in the
cybercriminal arsenal, affecting organizations across all sectors. By analyzing the breach and its
aftermath, this paper offers insights into best practices for cybersecurity resilience and incident
response strategies that can help mitigate future threats of similar magnitude.
