Authorities in Germany and the U.S. dismantled the central infrastructure of Kratos, a phishing-as-a-service (PhaaS) platform with global reach, and its developer was arrested in Indonesia.

During the operation, authorities seized more than 200 servers, effectively disrupting the malicious service and rendering it inoperable.

The action was led by Frankfurt’s Prosecutor General Office (ZIT), Germany’s Federal police (BKA), which worked in collaboration with U.S. law enforcement agencies.

BKA’s announcement characterizes Kratos as “one of the world’s most widely used criminal phishing services,” with confirmed victims across 35 countries, particularly in Europe and the United States.

“Authorities believe that more than 1,800 criminal customers purchased Kratos and used it to conduct roughly 15,000 phishing campaigns per month,” BKA announced.
