Physical Theft or Loss: Data breaches can occur through the theft or loss of physical devices, such as laptops, smartphones, or portable storage media, that contain sensitive information. If these devices are not properly secured, encrypted, or adequately protected against physical access, unauthorized individuals can retrieve the data stored on them.

Remote Attacks: Attackers target remote access systems, such as virtual private networks (VPNs), remote desktop protocols (RDP), or cloud services, to gain unauthorized entry into an organization's network. They exploit weak or stolen credentials, vulnerabilities in remote access software, or insecure configurations to breach the network and access sensitive data.

Supply Chain Attacks: Attackers target third-party vendors or suppliers that have access to an organization's systems or data. By compromising the security of these external entities, attackers can gain unauthorized access to the organization's network, systems, or sensitive data.

Advanced Persistent Threats (APTs): APTs are sophisticated, prolonged attacks orchestrated by skilled adversaries. These attackers employ a combination of techniques, including advanced malware, zero-day exploits, social engineering, and stealthy tactics to gain persistent access to a target's network, exfiltrate sensitive data, or maintain long-term control.

Skimming: Identity thieves use devices to capture credit card or debit card information during legitimate transactions, such as at ATMs or point-of-sale terminals.

Insider Involvement: In some cases, skimming operations involve insiders, such as employees of businesses or financial institutions. Insiders may collude with criminals by providing access to card data or assisting in the installation of skimming devices in exchange for a share of the stolen information or monetary gain.
