1111

1111, also known as Taiwan Job Bank 1111, is a major employment service platform headquartered in Taiwan that operates as a primary digital job bank connecting employers with job seekers. The organization facilitates the matching of labor supply and demand by maintaining extensive databases of candidate profiles, company listings, and job vacancies, serving as a central hub for Taiwan's workforce. Its platform allows individuals to create resumes, search for employment opportunities, and apply for positions, while businesses post openings and screen applicants. The scale of its operations is explicitly defined by a catastrophic data breach in October 2020, where hackers stole personal information belonging to nearly six million individuals, a figure representing approximately half of Taiwan's entire workforce at the time. This incident confirms the platform's massive user base and its integral role within the national employment ecosystem, handling sensitive personal data on a scale comparable to the size of the country's active labor market.

The organization's distinguishing attribute is its position as a dominant, high-volume intermediary in Taiwan's job market, a status underscored by its repeated targeting in significant cyberattacks. The 2020 breach, attributed to Chinese-linked actors who sold the stolen data on dark web forums, and a prior 2019 incident where approximately 200,000 member records were leaked on a hacker forum, collectively highlight the immense value of the data it aggregates and the persistent security challenges associated with that role. These events illustrate that 1111 processes and stores vast quantities of static personal identifiers—such as names, birthdates, contact information, and physical addresses—making it a lucrative target for cybercriminals seeking comprehensive datasets. While the provided context does not specify ownership structure or subsidiary relationships, the documented incidents firmly establish the organization as a critical infrastructure component for employment in Taiwan, whose operational success is intrinsically linked to its capacity to manage and protect a database of national workforce significance. The frequency and scale of the breaches serve as a de facto metric of its market penetration and the criticality of its data repository within the Taiwanese digital economy.
