23 Oct
Summary
- Microsoft partnered with Japan's police to disrupt cybercrime app stores.
- YAM Store, CoGUI, and Iron Man targeted over 150 countries.
- Illegal operations generated millions by scamming businesses and individuals.

Microsoft has announced a significant operational success alongside the Japanese National Police Agency, dismantling a network of Chinese-language cybercrime "app stores." These operations, known as YAM Store, CoGUI, and Iron Man, impacted over 75,000 organizations across more than 150 countries.
The criminal ecosystem provided pre-fabricated fake websites and scam messages, enabling cybercriminals to easily steal login and payment credentials. Some services employed sophisticated methods to evade security software. These illicit platforms generated millions of dollars for their operators.
Microsoft seized domains associated with the YAM Store, CoGUI, and Iron Man infrastructure. The company is continuing its work with law enforcement agencies globally to disrupt illegal operations that target both businesses and individuals worldwide.
