Citi has stopped issuing visas to its Visa customer service representatives after a security breach that allowed a hacker to steal information from the systems of the financial institutions.
The hack was discovered after a cybersecurity researcher discovered that Citi had not properly implemented its software for a vulnerability in the company’s Visa Application Processing System (VAPS), according to a blog post on Citi’s website.
Citi said in a statement that it had begun reviewing all of its systems and systems management procedures, and that the company had implemented a security audit of its VAPS systems.
The breach, which Citi said was discovered in mid-October, resulted in the unauthorized access of data, including account and passport information, and resulted in Citi halting its VAPI operations.
Citi announced the suspension after discovering the breach and is currently working with the Department of Homeland Security to address the breach.
The company’s CTO said in the blog post that CITI’s VAPs are highly secured, and the company has implemented a comprehensive security audit program that includes testing, analysis and verification of all of the company, its vendors and its systems.
CITIs goal is to continue to make security a top priority, he added.CITI said in its blog post:We have initiated a comprehensive, multi-disciplinary security audit and will work with our vendors and customers to continue implementing appropriate security measures to address this vulnerability.
