Data breach resulting in the theft of PII for approximately 900,000 customers. Exposure of personal and financial data, increasing the risk of identity theft and financial fraud. The breach originated from a third-party call center in the Philippines, illustrating the critical risk of supply chain vulnerabilities. While most affected users had partial data exposed, the leak of full bank accounts and government IDs for a subset of customers significantly increases the risk of financial fraud. This incident highlights the ongoing threat of ‘island hopping’ where attackers target weaker vendors to reach a larger target.
