Data Breach Summary
In a recent and deeply unsettling revelation, the fortified digital walls of GREE.cn, a prominent Japanese technology company specializing in mobile applications and services, were compromised by a malevolent cyber actor known as “sumo.” This breach, detected by InsecureWeb on September 25, 2023, unleashed an unprecedented data heist, with a staggering 10.8 gigabytes of sensitive information falling into unauthorized hands.
Where and How?
This disconcerting breach unfolded in the concealed recesses of a dark web forum, specifically on the cryptic “cronos.li.” The perpetrator, sumo, demonstrated an alarming level of sophistication in bypassing GREE.cn’s security mechanisms, which are typically considered robust. As a result, a substantial database containing critical details, including IDs, classes, CIDs, types, content, operator information, and operator contact numbers, was exfiltrated.
This colossal leak of information raises concerns about the potential misuse of this trove of data, as it exposes the inner workings and sensitive details of GREE.cn’s operations.
