Zeeroq

In 2019 an open directory was discovered on the demo.zeeroq.com domain containing approximately 250 separate combolists. The incident involved the exposure of over 200 million records due to a misconfigured server or open catalog. The files consisted of vast collections of credentials aggregated from various sources and previous breaches. The data was stored in a simple cleartext format making it highly accessible to malicious actors for credential stuffing and account takeover attacks.
