In February 2025, Thai and Singaporean law enforcement officers arrested a 39-year-old hacker who was behind multiple global data breaches. His activities resulted in the breach of more than 70 large databases containing more than 13 terabytes of personal data. The hacker operated under several aliases, including ALTDOS, DESORDEN, GHOSTR, and 0mid16B, and carried out attacks targeting companies in sectors such as healthcare, finance, retail, and others.
The arrest was the result of a joint operation between law enforcement agencies in Singapore and Thailand, with the support of Group-IB. The hacker stole data and sold it on the black market, using it for blackmail. During his career, he hacked hundreds of large organizations around the world. The hacker also used psychological pressure tactics, directly contacting the companies’ customers and demanding money through threats of leaking information.
The exposure of this hacker was made possible thanks to the cooperation of various law enforcement agencies and cyber intelligence. His activities were significantly complicated by the constant change of aliases and hacking techniques, which made him difficult to track. During the arrest, not only electronic devices were confiscated, but also luxury goods such as Chanel bags and other expensive items, which were likely purchased with money from the sale of stolen data.
The arrest of the hacker demonstrates the importance of cooperation between international law enforcement agencies and cybersecurity firms in the fight against cybercrime. It also reminds us of the enormous risks that companies and users face in the digital world and emphasizes the need to strengthen the protection of personal data.
